Primer for bottom paint is not necessary. However, if you use Tuff Stuffmarine epoxy primer on the bare fiberglass, it will provide protection against blisters and any moisture. It will also improve adhesion to the hull. Tuff Stuff marine epoxy primer will last for many years. It cannot be applied over paint, it must be applied on gel coat (bare fiberglass). It only needs to be applied once, while bottom paint should be applied every season or two depending on your conditions.
If you decide to useTuff Stuff, here is the link. You should apply at least two coats.
Marine Epoxy systems on the bottom of bare fiberglass is the best way to protect your boat against blisters. It also provides added adhesion of the bottom paint to the hull. Here are the steps that you need to take for proper application of a marine epoxy primer (barrier coat system) to the bottom of a boat.
Clean When painting a bare fiberglass / gel coat hull for the first time, it is extremely important that all contaminants such as grease, oil, wax, salt, or other foreign material are completed removed prior to sanding or application of a Sea Hawk System. Scrub the surface with a detergent soap and stiff bristle brush.
A. Clean and de-wax fiberglass hull with S-80 Wax N’ Grease Killersolvent based dewax. Saturate cheeseclothrag and wipe thoroughly to remove any cleaner and contaminants. Be sure to remove any residue before it dries and change rags frequently to insure contaminants are completely removed.
B. Apply S-90 De-Wax Etch & Cleanerwith a maroon 3M Scotch-Brite® padscrubbing thoroughly. Do not allow cleaner to dry on the surface and remove by flushing with water.Rinse entire surface with water and check for any beadingon the surface which will indicate that wax is still present. If necessary repeat step 2 again until the surface is contaminant-free. Choose your system below.
Apply Marine Epoxy Primer Seal the surface with 2-3 coats of Tuff Stuff Epoxy Primer. Apply the first coat of marine epoxy primer and allow the surface to dry to become tacky. Temperature and humidity affect the dry time, but you will know when to apply your next coat of marine epoxy primer once the paint film becomes “tacky”. You should be able to firmly press your thumb into the paint film and leave a thumbprint without any high build marine epoxy primer coming off the surface. You should use this method in between coats of marine epoxy primer and your first coat of bottom paint.
Tip: When applying marine epoxy primer over multiple days, it is always best to go overnight between coats of marine epoxy primer instead going overnight between the final coat of marine epoxy primer and the first coat of bottom paint. When over coating Tuff Stuff Epoxy Primer it is important to meet the required over coating times in order to achieve the best adhesion because temperature and humidity control dry times. It is hard to give exact times of cure. An easier rule in epoxies is when the coating is dry to the touch, yet still has some tack, it is ready to be over coated. However, if the coating is completely cured (after 24 hours) it needs to be thoroughly sanded with 80 grit sand paper to remove shine. If the marine epoxy primer is not sanded after full cure, bottom paint will not adhere.
Apply Bottom Paint to Marine Epoxy Primer Apply minimum of two coats of bottom paint. Allow 3 to 6 hours between coats and a minimum overnight dry. See the specific Technical Data Sheet for bottom paint being used. Some bottom paint may require more than 2 coats.
Below you will find a detailed gel coat preparation guide on how to apply gelcoat to your boat, RV or other surface. The secret to a good finish is to apply gel coat properly. The application of gelcoat and by pretty straight forward when you follow this guide.
Determine the Existing Surface: First thing you want to do is look at the surface on which you want gelcoat applied. If the surface is already coated with gelcoat, or if the surface is a fiberglass or polyester resin, then the application of gelcoat is a snap. If the surface is paint then the paint should be removed before the gelcoat is applied.
Prepping the Surface: Remove rails, cleats, louvers, snaps, striping tape, etc. Duct tape off adjacent gunwale molding, and deck fittings you are unable to remove. **NOTE** Duct tape is recommended over masking tape because it provides better protection. Remove seals from the edges of parts or fittings when doing a repair around that part or fitting. Take steps to cover and protect the rest of the boat before starting. When working on the deck or cabin, tarp off the adjacent areas. 3M and UV tapes , and masking papers are recommended.
Sanding Existing Gel Coat: You want to sand the surface to make a mechanical bond to the gel coat. Our technicians suggest the use of Dyekum Steel Blue Dye to be really thorough. Steel Blue is a dye you’re going to wipe on or you can use the blue dye spray. If you don’t see the blue dye again, you know you’ve sanded it all properly. Start by sanding the surface with 150 grit or sandpaper. The heavier fast-cut grits (40/80/100) are used to feather sand and ground out a routed area prior to filling. Also, they are used for the first sanding of gouges, dock dings, scratches, and blisters. When sanding areas that have been filled with putty we suggest using 40 or 80 grit sandpaper, depending on how large the repair is. Once the fill area is level or contoured to the desired shape, sand with 100 grit paper to remove the course scratches from 40 or 80 grit. You should also feather the surrounding area of the gel coat repair with 220/330. At this point, the repair is ready to prep and spray/brush with gel coat. Use 3M Abrasivesfor best results.
Preparing the Surface for Application: Next, you’re going to have to clean the surface. We encourage the use of Acetone, because it does not leave the residue and evaporates easily. When the surface is clean, you want to get moving fairly quickly; if the surface is sitting for some amount of time, you want to re-clean the surface. Dust and dirt particles are your enemy here, so make sure you clean the surface thoroughly. Determine whether you need one or two gel coat coats. If you change colors, it will require at least two gel coat coats. If this is going over a patch, at least 2 coats are recommended to get a uniform surface. Otherwise, there’ll be only one coat.
Method of Application: Next, determine if you are going to brush, roll or spray your gelcoat so you can prepare the gelcoat for application. You may either roll the gelcoat on, like paint, or spray it on, to apply the gelcoat. A Brushable Gel coat that can be applied with a brush and does not need any other additives except MEKP that is included with your Brushable Gelcoat. If you want to roll on a gelcoat, be sure to use a 1/8 “or 1⁄4” solvent-resistant nap. Be sure not to use foam rollers because they tend to leave the bubbles. If you brush on the gel coat, make sure to use a solvent-resistant brush.
Wax Additive: Add up to 4 oz of Wax Additive per gallon 1 oz per quart for tack free surface on the final coat, or if applying one coat a recommended film thickness. The Exterior Gelcoats that recommend a wax additive are included with purchase at Bottom Paint Store. (A wax additive is NOT used with Brushable Gel Coat.) You should only use a wax additive in the final application coat or if you are planning on only one coat.
Partall Film #10 PVA Surfacing Agent For Gel Coat Use this product as a surfacing agent when using Gel Coat without wax additive and typically larger spray applications. Partall Film #10 is a polyvinyl alcohol (PVA) water/alcohol solution of water-soluble, film-forming materials. This parting film is particularly recommended as a parting agent for separation between polyester or epoxy resins and various mold surfaces. It is not recommended for use with resins containing water or giving off water during cure (i.e., phenolics) or with automotive finishes, as damage may occur. Partall Film #10 will not shrink and pull away from corners or curved surfaces. After resin has dried, the film parts easily from the mold and is readily dissolved from the molded parts with water. An occasional coating of Partall Paste #2 is required on most mold surfaces before application of Partall Film #10. May be applied over gel coat as a surface cure agent.
Sea Hawk Patch Aid 8185:To be used in Sea Hawk Gelcoat only. Add 25-33% Sea Hawk Patch Aid 8185 when applying gelcoat for small repairs, to improve the working properties of traditional gel coat spray patches. Patch Aid is an additive that significantly improves the application, appearance and longevity of Sea Hawk Gel Coat patches, and also gives a faster cure, harder patch, superior gloss, consistent cold weather performance, superior color match, and less halo. Patch Aid also eliminates the need to thin, or add wax to gel coats prior to patching. Do NOT combine with Sea Hawk 8140. Use either one (8140,8145) but NOT both!
Catalyzing Gelcoat with MEKP: All gelcoat MUST be catalyzed with MEKP to cure. This should be added after all other additives just prior to application. Gelcoat requires Methyl Ethyl Ketone Peroxide or MEKP to enable the process of hardening. It’s a very small number. We suggest 1-1/4% to 1-1/2% by volume, i.e. 13-15 cc per quart. Darker colors need a little more catalyst for the same reaction, so you can catalyze up to 2%. All Gel Coats from Bottom Paint Store come with MEKP with each gelcoat purchase. Refer to the catalyst chart located on the product page for the gelcoat you are using or follow the label guidelines. As a general rule: The catalyst level (MEKP) should not exceed 3.0% or fall below 1.2 for proper cure. Ideal range is 1.8% @ 77°F. Gel time at 1.8% MEKP is 10-17 minutes. This time element is dependent on material temperature, room temperature, humidity, air movement, and catalyst concentration. Gelcoat should not be used when temperature conditions are below 60°F, as curing may be adversely affected. Be sure to have a good strategy when applying your gelcoat. Once you mix and catalyze, you have about 15 minutes to apply the gelcoat before it starts getting hard or starts to “gel.” The actual working time depends on the amount of catalyst and how hot the working conditions are. Anything below 60 degrees, and your gelcoat will not cure, but as you get warmer and warmer, your working time will decrease rapidly. At 70 degrees, you get 15 minutes, but at 90 degrees, you only get 5 minutes. If you need more time to work, be sure to sit the can in some cold ice water to cool it down to 60 degrees to allow you a little more working time.
1 ML = 1 CC
If using wood mixing stick, place stick in resin before adding catalyst so wood doesn’t absorb catalyst
Only catalyze slightly more than needed. Resin that cures still in the mixing pot is unusable. Mix small batches at a time since too much MEPK will result in hardening of the gelcoat way too fast! Refer to the catalyst chart located on the product page for the gelcoat you are using or follow the label guidelines.
Measure catalyst accurately. Under or over catalyzation retards curing and causes fading and chalking
All Gelcoats from the Bottom Paint Store come with the MEKPcatalyst but additional amounts can be purchased.
Applying Gelcoat by Brush or Roller – (Use a Brushable Gelcoat) : When applying gelcoat by brush or roller, we recommend the Ultra Plus Brushable Gelcoat. (other Gelcoats are best applied by Spray) The Ultra Plus Brushable Gelcoat is designed to self-leveling and is much easier application. It allows for a much smoother finish and less time finishing the gelcoat. It is easy to use for the “do it your selfers’! Choose a good pure (natural) resin resistant bristle brush with tapered ends. Avoid brushes that are either too stiff or too soft. For most work, a 3″ or 4″ wide brush will suffice. If there is a trim color, you should have a narrow trim brush on hand. Our Brushable Gelcoat comes with MEKPhardener with every purchase, but you may need more which you can purchase as an option depending on the application, temperature and other environmental factors. Please refer the to Catalyzation chart on the Brushable Gelcoat page or on the label. Gelcoat needs to be applied evenly. We suggest a thickness of 18-20 mils to properly cure. The thickness of the matchbook cover is approximately 18 mils. If you’re not sure how thick it is, pick up a mil gauge. This is a simple, easy way to see the thickness of your gelcoat. Gelcoat needs to be applied evenly. We suggest a thickness of 18-20 mils to properly cure. The thickness of the matchbook cover is approximately 18 mils. If you’re not sure how thick it is, pick up a mil gauge. This is a simple, easy way to see the thickness of your gelcoat.
Initially spray a cover coat as smooth and evenly as you can to cover your repair. This coat should be mostly in the repair area, and may be repeated. Sanding between coats is not necessary unless a surfacing agent has been added to your gel coat. Once your repair is covered, feather a ‘flow’ or sanding coat on the masked-off area making layered passes to avoid a buildup of gel coat in any one area. Each of these coats of gelcoat may involve several passes. Be even and consistent in your gun movement, overlapping each previous pass slightly and not hesitating on the ends. When spraying to a radius, flow the gelcoat to the tape. In open flat areas, layer passes. Final thickness should be 16-20 mils minimum or the gelcoat may not fully cure. Gelcoat needs to be applied evenly. We suggest a thickness of 18-20 mils to properly cure. The thickness of the matchbook cover is approximately 18 mils. If you’re not sure how thick it is, pick up a mil gauge. This is a simple, easy way to see the thickness of your gelcoat. As soon as you are done spraying, clean your sprayer fully with acetone. Most re-sprayed gel coat will cure in 2-4 hours, although overnight cures are ideal.
Finishing your Gelcoat Application: If you’re using our Professional Grade Exterior Gelcoat, you’ll be ready to sand and buff your freshly gelcoated surface after about 1- 3 hours. If you’re using our Brushable Gel Coat, you’ll want to let it cure overnight to make sure it’s completely cured. Begin wet sanding with the finest grit that will remove orange peel in the re-sprayed area. This will avoid unnecessary sanding scratches. Usually 320 or 400 grit wet paper is sufficient for the initial sanding. Going up to 400, then 600, and eventually 800 grit sandpaper. You can use an 800 grit compound for the gelcoat at this stage. You want to use a buffer that turns 1600-3000 RPM. The car polishers won’t work if they’re spinning too slowly, so you want to check the speed of the spin. It’s best to do a 4 foot by 4 foot area at a time. Every 10 feet or so, you’re going to want to clean your pad with a spur or some air to make sure the contaminants don’t scratch your surface. If you want a perfect, glossy shine, use a machine glaze and then two wax coats, and you’ll have a stunning, glossy professional finish.
DO NOT WORK IN DIRECT SUNLIGHT -Choose a shady location or an overcast day. You should catalyze your material so that it cures as quickly as possible within your working time. Generally mix one-pint batches. A good practice is to pour the mixed gel coat from the mixing container into another container used for application. This further assures that no uncatalyzed material is clinging to the sides of the pot. “Lay on” the gel coat in a heavy thickness (about 10 mils) using horizontal strokes, and working from top to bottom. Avoid re-brushing as this could remove the waxy surface additive. Remember to always lap wet. Generally, one heavy coat is sufficient. However, if you have opacity problems two coats may be necessary with a light sanding between coats. Once the coating (gelcoat) has cured, it should be block sanded using a 250 wet grit paper to remove all brush marks and high spots. Following this, it should be wet sanded with 320, 400 and 600 wet grit paper, buffed, polished and waxed.
Clean repair area and all tools with acetone prior to application
Pot life (amount of time for application of the product) shortens dramatically as you mix larger batch sizes. Keep in mind that you have a limited time to apply what you have mixed (usually between 5-15 minutes).
Measure catalyst accurately. Under- or over-catalyzed gel coat will cure slower and look faded or chalky.
Use the recommend thinners / addtives only which are listed on the gelcoats’ product page. (No Thinning Necessary for the Ultra Plus Brushable Gelcoat)
Gel coat will not fully cure without adding a surfacing agent or over spraying with PVA
Check color thoroughly before applying. Gelcoat will not darken or change colors when it dries. The color wet is the color when dry.
Store gel coat in a cool, dry place
Gel coat should be applied in temperatures of 60ºF to 80ºF
Always use eye and hand protection
Gelcoat should not be applied over paint, wood, metal or concrete. It usually will not adhere to these surfaces.
Gelcoat will not fully cure without adding a surfacing agent or wax additive sanding aid. You can over-spray with PVA before gel coal reaches its gel stage (5-10 min.), or adding 1oz per quart/ 4 oz oer gallon of wax additive sanding aid.
Read all warnings on product labels and only use additives recommended as described per each product.
There are two Evercoat gelcoat repair kits available: Large Gelcoat Repair Kit, which contains 4 oz. of polyester gelcoat paste with liquid hardener, coloring agents, cleaning solvents, mixing cup and stick and Mylar film for smoothing the repair surface. Small Gel Coat Repair Kit, which contains 1 oz. of polyester gelcoat paste and all the same components as the larger kit above, except for the cleaning solvent.
Make sure damaged areas are clean and free of dirt, grease and wax, etc.
Enough Gelcoat paste should be added to a plastic mixing cup to make all repairs. One of the six basic colors may match the gelcoat. If so, mix approximately 1 part pigment to 20 parts gel paste (in other words, fill the cup 1/4in and add approximately 1-2 inch bead of pigment from the tube). The pigments can be intermixed to achieve various shades. Please refer to the color match chart for mixing suggestions. NOTE: Exact color match will be difficult, but weathering will blend in slight color differences.
After the color has been matched, take enough of the pigmented gel paste to fix a damaged area. Place it on a clean piece of cardboard and mix with several drops of liquid hardener. NOTE: adding liquid hardener will darken the color slightly! Four drops of hardener in 1 teaspoon of gelcoat paste will give approximately 15 minutes of working time before the material begins to gel. Mix the liquid hardener thoroughly into the gelcoat paste.
Apply catalyzed gelcoat paste to the damaged area, working in into the area with a spatula or plastic spreader. Squeeze off the excess material.
For greater smoothness and higher gloss, this repair should be covered with a piece of the enclosed clear plastic release film, and left to cure.
After approximately one hour, remove the plastic film and clean the repaired area with the enclosed solvent and a clean cloth (applicable to 100668 large kit only )
Deep damaged areas may require several applications.
In order to have a form from which to develop your mold, you must either build the article from scratch using wood, plaster, polyester putty, formica, sheet metal, etc. or you must have on hand a completed article which you wish to duplicate. The latter is of course the fastest method. The plug is generally a male model exactly like the item you wish to fabricate in every detail. If the plug does not have draft (taper) then you will have difficulty getting parts off. If the plug has reverse bends, like many canoes, then you will need to make a split mold which can be spread or taken apart.
If the plug contains soft materials on its surface such as plaster, wood, or putty, then it will have to be sealed with lacquer orresinto fill the pores. If plaster is used, it must be oven dried and then sealed.
To prevent your mold from sticking to the plug, the plug must be coated with plastic film known as “PVA.” This is a plastic dissolved in alcohol and has a green color. It can be brushed or sprayed on, but the best system is to spray on three thin coats, the first being a “mist coat.” The appearance will then be green. Each coat must dry half an hour or so and there must be no pools or drips to blemish your mold surface. For the easiest possible parting, before applying the PVA, apply a soft wax (TR Mold Release) formulated for use with PVA. After the third coat ofPVA has dried, a coating of this wax can be gently applied over it for easy parting.
The first step is to apply a gelcoat which will be the mold surface. The gelcoat must be “exterior gelcoat” (wax free). If many parts are to be taken off the mold, it is desirable to use a “tooling gelcoat” which is designed to give longer life in mold use. The gelcoat should be in contrasting color to the surface of the part you will make. Since most parts are light colored, black gelcoatis commonly used. This facilitates spraying up a uniform thickness of light colored gelcoat since the black will show through thin spots.
If the gelcoat is to be brushed on, two coats must be applied, and the first coat must cure several hours before the second coat is applied. The best means of gelcoat application is a simple gelcoat gundesigned for the purpose and easy to clean. Air pressure of 80 to 90 pounds is desirable. Gelcoat must be applied at least 15 mils thick, or a quart to every 25 square feet of surface. If the plug was rough so that considerable sanding of the gelcoat will be necessary, then double the application. Before applying the gelcoat, it must of course, be catalyzed with MEKp peroxide hardener, using from one to two percent. All gelcoats from the Bottom Paint Store include the MEKp.
When the gelcoat has cured so that it cannot be scratched off with the fingernail at the edge of the mold, which takes from 2 to 4 hours to overnight in cool or humid weather, you are ready for the “skin coat.” This is a layer of ¾ or 1oz. fiberglass mat, thin enough so you can see and remove all air bubbles entrapped by the resin when you “wet-out” the mat. The resinshould be applied with a mohair roller or brush until no white fibers remain. Any air bubbles are then eliminated with a grooved plastic or metal laminating roller. The polyester resin used should be “lay-up resin,” which is wax-free. Be careful not to over-catalyze when laying up the glass. Above 75°F one 10-15 cc of hardener to the quart will generally suffice. Below 70°F, 20 cc per quart. Do not work below 65°F.
In laying up a fiberglass mold, warping can be avoided by allowing each layer to “kick” or gel before proceeding with the next layer. For a large mold, it is good to apply just one layer per day. After the “skin coat,” you can use 1½ oz. fiberglass mat for a faster build-up. Generally, woven roving is not used in molds because the pattern transfers through the mold to the gelcoat. If it is necessary to use woven roving fiberglass for strength in a large mold, it is applied after a thickness of 3 or 4 layers of mat has cured hard. The thickness required in a mold depends upon size and shape and the number of parts to be taken off. For a dinghy mold to be used only a few times, four layers of mat might be adequate.
Removing mold from the plug
Allow mold to cure several days if possible so it will hold its shape. The first step is to trim the excess laminate back to the molded edge. This is easily done with a saber saw and a metal-cutting blade. The edges are sanded carefully until the line between the mold and plug is exposed. Then a sharpened “tongue stick” is forced between mold and plug to separate the edges. The stick is then pulled clear around the plug until all edges are free and no bridges remain. Avoid using metal tools for this purpose as they will scratch the mold surface. Then the mold should pull free of the plug. If not, the parts can be flexed or pounded gently with a rubber mallet. If necessary, air or water can be forced under pressure between plug and mold. A hole can be drilled through the interface for this purpose. PVA is water soluble, which facilitates parting with water pressure.
Polishing the mold
Depending upon the condition of the mold surface, it may have to be sanded with 220 grit working up to 600 grit wet or dry. The surface is then compounded with regular and fine finish compound formulated for fiberglass work. Best results can be achieved by using special compounds such as 3M Finesse-It Marine Paste Compound to bring out a mirror finish.
Before using a mold, it should be allowed to cure a week or more if possible. Be sure to use PVA parting film and soft wax for the first 3 or 4 parts, after which a carnauba wax can be used.
Outdrives are difficult to keep free of growth. The main reason for this is that traditional copper-based bottom paints cannot be used on an aluminum outdrive. Doing so will result in serious corrosion from the aluminum reacting to the copper in the paint.
When painting an aluminum outdrive you must use a copper-free bottom paint. There are a couple of different brands out there. Interlux Trilux 33 (The most popular) , and Sea Hawk Smart Solution (The best). Trilux is the most popular and easy to find at your local West Marine. However, the results are not as impressive as Sea Hawk Smart Solution (available in pint size black as Outdrive Paint) that uses the newest metal free technology. You will get the best possible results with Smart Solution, and is becoming more and more popluar as the best solution for painting an outdrive. It is also the best priced of the two, but is yet not available in an aerosol spray. You can get a quart and brush it on, or you can spray it with a conventional spray gun.
Typically there is less growth in fresh water than in salt water. For that reason, bottom paint used in fresh water usually have less active ingredients (copper, zinc, etc.) to prevent growth. Most bottom paint for salt water can be used in fresh water. However, there are some exception, such as, Interlux Micron 66. This paint is limited to salt water only. Using Micron 66 bottom paint in fresh water, or where there is a lot of fresh water run off, will result in failure of the coating.
Consider using a bottom paint that is good in both fresh water and salt water. All of Sea Hawk Paints , Blue Water, Pettit or Interlux bottom paints are good for either types of waters and are considered both fresh water bottom paint and salt water bottom paint. You never know where you might travel that will have significant fresh water run off!
Preparation is key when painting on any surface. Applying bottom paint is not the cleanest of jobs, but it is really simple to do. Below you will find the exact steps to insure a good bottom paint job, whether you have a new boat, or a boat that has existing bottom paint on it.
Preparation for Bare Fiberglass When painting a bare fiberglass gel coat hull for the first time, it is extremely important that all contaminants such as grease, oil, wax, salt, or other foreign material are completed removed prior to sanding or application of a Sea Hawk System. Scrub the surface with a detergent soap and stiff bristle brush.
Clean your boat following options A or B
A. Clean and de-wax fiberglass hull withS-80 Wax N’ Grease Killer solvent based dewax. Saturate cheeseclothrag and wipe thoroughly to remove any cleaner and contaminants. Be sure to remove any residue before it dries and change rags frequently to insure contaminants are completely removed.
B. Apply S-90 De-Wax Etch & Cleaner with a maroon 3M Scotch-Brite® pad scrubbing thoroughly. Do not allow cleaner to dry on the surface and remove by flushing with water.Rinse entire surface with water and check for any beadingon the surface which will indicate that wax is still present. If necessary repeat step 2 again until the surface is contaminant-free. Choose your system below.
Apply Bottom Paint Apply a minimum of two coats of Sea Hawk bottom paint. Allow 3 to 6 hours between coats and a minimum overnight dry before launching. See the specific Technical Data Sheet for the bottom paint you are using. Some bottom paint may require more than 2 coats.
Tip: Epoxy systems on the bottom of bare fiberglass is the best way to protect your boat against blisters. It also provides added adhesion of the bottom paint to the hull.
Preparation Over Existing Bottom Paint
Clean the boat Clean the existing boat bottom paint with a pressure washing. If you have excess build up of growth, you can remove this by scraping and/or using muratic acid. Try to get all growth residue off the existing old bottom paint so that you have good adhesion of the new bottom paint.
Scuff Sand the surface
Scuff sand to a dull looking surface with 80-100 grit (no finer) sandpaper, then rinse with water and allow to dry. If your old bottom paint is really chalky, consider giving it a more agressive sanding to insure proper adhesion of the new bottom paint.
Apply Bottom Paint Apply minimum of two coats of Sea Hawk bottom paint. Allow 3 to 6 hours between coats and a minimum overnight dry before launching. See the specific Technical Data Sheet for bottom paint being used. Some bottom paint may require more than 2 coats.
If you do not have any coatings at all on the bottom of the boat, we suggest to sand the hull with 80 grit and then apply Tuff Stuff High Build Epoxy. It is a water tight barrier coat designed for use under the waterline and with aluminum hulls. Use 2 coats. You can apply the 2nd coat within a couple of hours of the first coat. (up to 6 days)
After you apply Tuff Stuff marine epoxy primeron hull, be sure to use an aluminum safe bottom paint. The bottom paint needs to be applied the same day as the Tuff Stuff marine epoxy primer. Bottom paints in general are designed to repel hard growth. Smart Solution is an excellent bottom paint for aluminum hulls when in salt water. We recommend Mission Bayfor fresh water. I have listed links below to the products described above. These can be brushed, sprayed, or rolled. If you already have coating(s) on the hull, pressure wash, sand with 80 grit, and then apply Smart Solution.
As you haul your boat out of storage you may want to get the gelcoat shining once again. Use the steps below as needed:
Which Products To Use: If your boat is new and the finish is still in good condition with little to no oxidation, you can use a one-step clean-and-wax product that combines washing and waxing in one step. We recommend using the 3M Marine Cleaner and Wax.
If your boat has light gelcoat oxidation use the least aggressive method, if possible, to prolong the life of gelcoat. We recommend cleaning with marine boat soap and buffing with the 3M Imperial Compound. Avoid direct sunlight and room temperature is best for application.
Note: An easy way to determine if gelcoat is oxidized is by wiping your hand across the surface. If any chalk wipes off on your hand, the gelcoat is oxidized and you will need to wash and buff the surface before polishing.
Follow these three simple steps to polish your gelcoat:
Step 1: Once you know which polish to use we recommend using a high-quality microfiber towel to apply the product. Avoid low-quality towels because they will shed fibers and leave streaks and residue on the boat.
Step 2: Wet the microfiber rag, remove any excess and apply a tablespoon of polish to the rag. This amount of polish will work for a few square feet. Remember, you want to work in small areas in order to cover the entire surface correctly.
Before buffing, spread the polish evenly across the boat’s gelcoat. You will get the best results when working the polish into the surface with circular motions.
Step 3: Once the polish dries into a haze you can remove it with a clean dry rag. Make sure you get in all the nooks and cracks for a smooth beautiful finish.
If your boat has been in contact with the elements over long periods of time (10-15 years), the process of restoring the appearance of the gelcoat will take some additional steps.
Step 1: Clean the surface. For boats that need a more aggressive cleaning just wash the surface and remove any loose contaminants. You can use a non-abrasive light detergent (marine boat soap) to remove all surface dirt and all previously applied coatings. If you need something stronger to remove surface rust, oil, tar, algae discoloration, black streaks caused from water runoff, exhaust and waterline scum, or other stains we recommend using an acid-based stain remover like Hammerhead Hull Cleaner. It is important to completely remove all stains before waxing, or you’ll seal in the stain.
Step 2: Select your compound. If your boat is a bit more oxidized a rubbing compound (liquid abrasive which “sands” your hull) is needed, but do so carefully as you can run through the gelcoat. The more faded your hull the more compounding you’ll need. The 3M Imperial Compound usually applied with a polisher if possible and compatible 3M pads, like the white 100% wool pad, recommended by 3M. Keep product off bottom paint, if applicable, by taping off as it can spatter. If the compound isn’t strong enough for your level of oxidation and scratches, then you may need to “pretreat” with a 1200 (or 800) grit as needed prior to the compound.
Note: When buffing, you should work on small sections of the hull (3-5ft sections is recommended). It is important to keep the wool pad damp. If you notice the pad is dry and the wool looks ‘matted’ after working the material into one area, just rake the wool back into form with a pad spur and re-wet the pad to continue with the application.
