DO: 1. Wash the surface regularly with Awlwash (73234) or Awlwash 2.0 (73235) and water. 2. Use only mild solvents to remove stubborn stains. Awlprep T0008, mineral spirits and xylene are acceptable for use on Awlgrip HDT. Do not allow solvent to dry on the surface or puddle and soak into the surface. Wash these areas with Awlwash and water to remove solvent residue. 3. Always thoroughly rinse surfaces with fresh water after cleaning with Awlwash or solvents. 4. Use distilled white vinegar and hot water to remove stubborn salt stains. Washing with Awlwash after use of vinegar is recommended. 5. Use Awlcare (73240) by hand only to remove mild diesel soot stains. Protecting the surface with Awlcare will help maintain the gloss of Awlgrip HDT. Awlcare is a hand applied, non-abrasive, synthetic polymer. It will remove mild stains, water spots and diesel soot while increasing resistance to attack from acid rain and other pollutants, when applied regularly.
DO NOT: 1. Do not use traditional waxes. Awlgrip has developed Awlcare Protective Polymer Sealer for those who want to enhance their finish and need the additional cleaning power of a hand applied, dry wash product. 2. Do not use abrasives, scratch pads or polishing compounds. Scratching the surface gives dirt a place to cling while wearing out the resin layer. Using abrasives of any kind will reduce the overall life of the finish and voids the Awlgrip Limited Warranty. 3. Do not allow contact between the Awlgrip HDT and teak cleaners. 4. Do not allow metal polishes to dry on the surface of Awlgrip HDT. Metal polishes may discolor and stain the painted surface. 5. Do not use strong solvents (eg. lacquer thinner, M.E.K., acetone) to clean Awlgrip HDT. 6. Do not allow wet equipment (e.g. seat cushions, coils of line, sails, sail covers, coolers) to trap and hold moisture against Awlgrip HDT. 7. Do not ‘shrink wrap’ or tightly bind Awlgrip HDT surfaces with plastic wrappings. The cover system, whether synthetic or natural fiber, should be ventilated to allow the coating system to ‘breathe’.
The surface preparation advice provided, and equipment suggestions, can be used as a guide. Preparation techniques and results will vary according to individual conditions, equipment choice/condition and other factors. Testing on a non-critical area should be carried out prior to full-scale preparation. Awlgrip HDT should be applied over Awlgrip 545 Epoxy Primer or previous Awlgrip Topcoat/Awlgrip HDT/Awlcraft 2000. Over Awlgrip Topcoat/Awlgrip HDT/Awlcraft 2000 topcoat sand topcoat with P400 to remove the gloss and clean with surface cleaner T0170 (US) or T0340 (EU) using the two cloth wipe down method. Avoid painting in direct sunlight. Do not apply paint materials to surfaces less than 5°F (3°C) above dew point, or to surfaces warmer than 105°F (41°C). Ambient temperature should be minimum 55°F (13°C) and maximum 105°F (41°C). At standard conditions (77˚F (25˚C), 50% R.H.), avoid applying topcoats when the temperature could drop below the dew point within 6–8 hours after the application.
Mixing & Reductionof Awlgrip HDT Mixing and reduction requirements will vary according to individual conditions, climate, equipment choice/condition and other factors. Mixing and application of a small sample before full-scale application is recommended. Mix Ratio (by volume) – 1:1:0.25 (Base : Curing Solution : Activator) (eg 1 Gallon:1 Gallon:1 Quart or 100:100:25ml). Induction time = 15 minutes. Mix to a smooth, homogenous mixture Awlgrip HDT is designed for spray application only. Correct choice of activator must be made according to the application conditions and project size. General guideline: 15-23ºC OA0020 20-30 ºC OA0015 (US only) >30ºC OA0010
1. Mix all 3 components of Awlgrip HDT thoroughly, especially the base. Mix by volume to a homogeneous mixture:
For example, mix 100ml OC series, 100ml OC0010 & 25ml OA0020 (or 32 ounces OC series, 32 ounces OC0010 & 8 ounces OA0020). Keeo in mind that adding more activator into the mix may compromise pot life and could affect the flow of the product. 2. Once the product is mixed, ensure at least 15 minutes induction time. If the induction time is not followed, the product may down gloss / haze once cured. 3. Initial spray viscosity should be 14-20 seconds (DIN4 or equivalent) and varies with the application conditions. The best choice of activator will depend on application conditions and boat size.
As a general guideline (see below):
Application & Conditionsfor Awlgrip HDT
4. Application equipment: Gravity or pressure feed, air atomized spray or electrostatic spray 5. The primed surface must be clean and dry. 6. Apply 2 coats of Awlgrip HDT, this should be sufficient to achieve the correct DFT of 50-75 microns (3mils) DFT. However, some colours may require additional coats to achieve full hide / opacity and colour development. Application of the first coat should be approximately 75 microns (3 mils) WFT and application of the second coat should be approximately 100 microns (3.9mils) WFT. The surface may not become completely ‘tack free’ in between coats, however it is recommended to wait at least 30 minutes between coats (this time will vary depending on activator selection, temperature and humidity and air flow) 7. Awlgrip HDT has a relatively short pot life compared to Awlgrip topcoat, so for optimal performance prepare a fresh mix for each application. Don’t mix the new & old paint together as this may compromise the final finish. 8. The Awlgrip HDT activators can be blended together to suit not only environmental conditions but also project complexity. For a good starting point use a 50/50 OA0010/ OA0020 blend (or OA0015) then adjust to your preference. 8.1 To achieve a longer pot life or longer wet edge, the blend of A0010 and A0020 should be adjusted to include more A0010. 8.2 Similarly, for small areas or where drying time needs to be reduced, the proportion of A0020 should be increased.
9. Even if temperature has a greater effect on the cure and the potlife, humidity to some extend can also have an influence on the flow and performance of the product. 9.1 In cooler humid conditions it is suggested to either use only OA0020 or a blend of OA0020 and OA0010 with a higher proportion of OA0020 to OA0010. Example 75/25 OA0020/OA0010. 9.2 In hot humid conditions it may be necessary to increase the proportion of OA0010 and decrease the proportion of OA0020. Example, 75/25 OA0010/OA0020. Even in hot humid conditions, it is not recommended to solely use OA0010 due to the risk of moisture causing down glossing. 10. When first using Awlgrip HDT, it can apply differently to other topcoats currently in use. To help with this, up to 12.5% of T0002, T0001, T0003, T0005 or T0031 can be added to help with wetting out of the surface. Using extra reducer may require an additional coat to be applied and will mean the product is no longer ‘VOC compliant’. Once applicators are used to the behaviour of HDT on application, a similar quality of finish can be achieved without the addition of extra reducer. It is recommended to mix separately the Activator (OA0010, OA0015, OA0020) in equal amounts to the chosen reducer. This mix can then be added to the 1:1 base & curing solution at 25%. This mix will contain 12.5% Activator (as recommended) with 12.5% reducer; from a painters perspective this gives a 1:1:0.5 overall mix ratio. 11. Thanks to the activator/ reducer choice based on temperature, Awlgrip HDT has been proven to be a very adaptable product. The chart on page 1 is to be used as a guide only. In low temperatures, the standard paint mix with fast activator works very well. On larger surfaces, the addition of standard solvents helps to carry a wet edge if the applicator is struggling. For hot weather, OA0015 activator works well. If the applicator is struggling with wet edge, the addition of solvents helps. It is recommended when blending the activators to use the two extremes OA0010 Slow) and OA0020 (Fast) this allows more control. In low temperatures, we recommend T0001 or T0002; in medium temperatures T0003 and in hot temperatures T0005. In hot to very hot weather T0031. Start with the addition of 5% solvent. It is recommended for larger applications that a pre-shoot on panels is to be carried out, “to enable applicator to choose” the best optimization for the size project and conditions. DRYING TIMES & REPAIRS for Awlgrip HDT 12. If environmental conditions require that the product dries faster (cooler more humid conditions), add slightly more OA0020 into the mix. Keep in mind this may compromise pot life and could affect the flow of the product. Also, in that case the product is no longer VOC compliant. 13. Awlgrip HDT has a new repair process compared to the standard Awlgrip repair. See the Repair & maintenance brochure for further info. 14. Awlgrip HDT can be harder to polish therefore we only recommend this for repairs and to remove localised defects. If working in an environment where you know you’re going to polish the whole boat, Awlcraft 2000 is the best choice. 15. Polishing Awlgrip HDT : Always test a small, low visibility area (or a sample panel) first before proceeding. Certain color shades may not be suitable for polishing. The tone of the color may be affected during sanding or aggressive polishing. Multi-stage sanding & polishing systems can also be used. You should contact your local supplier for further information.

Application equipment and parameters are given as a guide. Actual equipment choices will vary according to application conditions, equipment condition and other factors. Testing on a non-critical area should be carried out prior to full-scale application. Contact your local technical service representative for further advice if necessary. To ensure optimal adhesion between coats Awlgrip HDT should be applied according to the overcoating intervals as described in the Recoatability & Drying Times section. Apply a full coat of Awlgrip HDT to the surface. Allow tack coat to “flash off” 30-45 minutes depending on application conditions. Apply a slightly heavy second coat. A third coat can be applied to reach DFT if needed.

Sea Hawk Aluma Hawk Paint Reviews
Seahawk aluminum boat paint is perfect. No primer required. I’ve used this paint for two years with excellent results. – William E.
Great product. – Kody L.
Very impress with the paint covering, 1 1/2 half gallon for my 20 feet pontoon.- Cristian V.
Adhesion seems better than most paints even when not fully cured. Liking what I see so far. – Mark L.
Great paint and easy to use. Took a little bit longer to dry than expected, but that was mostly a humidity issue on my end. Looks great and it will buy it again if I need some more for anything.- Eddie C.
Haven’t used it yet but I ordered it because of its good reviews on YouTube.- Jesse H. Great product. Bruce D.
Excellent product for my Jon Boat- Dennis E.
Looks great! Sam B.
I learned several things about this paint; 1. Make sure you apply it soon after you receive it. If it’s going to sit for a couple of weeks, you will need to stir it very well to break up chunks in the bottom of the can. 2. Two quarts are not enough to paint the bottom hull of a 14-foot aluminum Jon boat. It will take at least 3 quarts for 1 coat. 3. Wear gloves. If you get this on your hands, it will take longer to get off than regular paints. 4. It takes a week to cure. It says so on the can and I can see that. Even though the paint appears dry after a few hours, it’s still tacky. So, you will need to have some patience. Seriously, this is not like painting other objects like wood. Read all the directions and act accordingly. Keep in mind that this is for boats that will routinely be out of the water. It has no anti-fouling properties, and that’s OK if you’re not going to leave it in the water. Personally, I live in a desert area of Arizona, so not an issue for me. – Kevin P.
The best product for aluminum boats.- Robert D.
Purchased an older small used pontoon for our no motor lake. The bottom crud was like cement and I eventually used a sand blaster wand attachment to my power washer to clean of this crud (unreal). Chose Aluma Hawk paint for the sand blasted pontoons and it worked great. This paint needs to be used in a WELL ventilated area!!! I was outdoors painting with a roller on a calm morning and decided to wait till the wind picked up to finish. Tough durable and easy to use. The green makes it look like its from the military surplus! Love it. Certainly the fish will be confused. LOL.- Keith B.
Smooth application.- Brad H.
Very good paint. – Chris T.
I used a roller went on smooth. – Roger C.
The paint match was pretty close to what the previous owner said he put it on the boat… I only did the transom and some touch up on the sides. Good quality paint for an aluminum boat.- Rich H.
I purchased the Aluma Hawk 7031 lite gray – 1 gallon, which gave me 2 coats on the bottom & 1 coat inside. The factory didn’t recommend spraying the paint, so i rolled it & brushed it on. The paint dries quickly, so you have to work fast to maintain a wet edge. I did small sections at a time to make sure I got even coverage. – Russell S.
Haven’t used it yet. – Joe S.
Love this paint. I painted my jon boat years ago with this stuff. It holds up, doesn’t fall off or fade. Added pods to my boat and had to get another quart. The color matched really well.- Steve K.
Great paint, just needs to be shaken before shipping.- Greg M.
This paint if fantastic! It adhered to my boat very well and it only needed one coat to cover evenly. – Arnold B.
Met all my expectations for painting exterior of houseboat. I strongly recommend!- Marsha M.
Best I ever used on alum!!!!!!!!!!!!!!!!!!!! – Herman B.
The Value is in the Lasting Performance so I shall see. Putting it on, one NEEDS to KNOW what they are dealing with BEFOREHAND as far as Application, in knowing this project should come out perfect. Price of this product should be determined by it’s worthiness over time. Clean Up be SURE to use right Measures and Tools.- Jerry H. Works good, dries well, one quart did a first and second coat on our jonboat.- Lindsey M.
Anticipating the paint will be great- Paul M.
Great products. – D. Mendez
Great product. Best bottom paint I have used yet. Good ventilation required. -Jon B. Awesome- Todd Z.
Paint was as advertised. Very pleased with product. Would highly recommend.- Jerry R. Easy to apply and dried quick, didn’t even really need a second coat but put one on anyway. -Sarah L.
Applying the product now and appears to be coating and covering as described. The painting (job) isn’t complete yet so I can’t comment on life longevity or wearing but satisfied so far. – Jason K.
This appears to be a good quality product but is not real user friendly for DIY due to the fumes and the fact that MEK is needed for clean up. – Douglas L.
So far pretty good, it’s been about six months now since application. I recommend reading the directions very well, it tells you exactly how to thin and apply with the exception of what type of roller to use, I used a 1/4 nap roller but seemed to go on pretty thick. I had to thin it a bit more than what it said in order make it a bit easier, it recommends rolling as best method but I believe spraying would be better. A 16 foot long 5 foot wide vhull took about a gallon and a half to paint but I believe it is because it was going on pretty thick, to spray it says can be thinned 50% but for roller or brush only 10% which seemed to thick and not much coverage, either way you have to move pretty quick because it will flash pretty fast. It dried to touch pretty quick but due to the thickness from rolling it seemed to take forever to fully dry and or cure during which time it was still pretty soft and easily scratched off. After being left to sit and fully cure/harden I will say the stuff seems pretty hard and tough as nails. I used the sand color and if an when the time comes to paint the boat again I would use it again only spray it . I initially bought a gallon and a quart but soon realized it was going to be enough so I bought another gallon and still have about half of it left, I applied two coats to the entire boat both inside and out.- David P.
Great- Todd Z.
The paint went on as expected will have to wait and see how it holds up.- Howard B.
I thought the value was great even though I haven’t used it yet due to my marina being backed up with haul outs so Ill probably get hauled out after hurricane season is over, plus it will be cooler then as well.- Michael W.
The quart I bought was surprisingly heavy but instructions were clear and it was easy to apply. Certainly recommend gloves and a disposable brush. – Peter S.
Boat had never been painted and I prepped and applied 2 coats below the waterline and 3 coats on the waterline . Held up for 2 years in coastal NC waters . Very little growth to remove . Pressure washer blew most of it off . I would call Sea Hawk Cukote a very good product. – D. Bordeaux
After more than 40 years experimenting with different bottom paints on many boats, I’d have to say Sea Hawk paints are the best (least fouling, longest-lasting) ablative paints I have found. – Stephen P.
Quick delivery good pricing. – Robert S.
I kept my sailboat on the Chesapeake in an area with warm brackish water very conducive to barnacle growth. Cukote worked better. – Robert P.
Excellent product. Alfred L.
IMO, this is the best bottom paint. Only requires one coat. – Gerald D.
It is on our boat now and we needed some touch up. – Carol S.
Great product to use on boat bottoms. – Jeffrey R.
Cleaned the surface, highly recommend a fan or 2 when using. Does have strong odor like any reducer or thinner. – Peter P.
A high quality epoxy paint. I will order it again. – Edward O.
Applied well, pretty happy so far! – Sam B.
Love it. Easy to work with and tough when cured ! Easy to wet sand also in prep for color coats ! – James W.
Very easy to use, just follow the directions. I have not put the boat in the water yet, but I don’t forsee any problems. – Sharon T.
The Sea Hawk Tuff Stuff was very easy to work with and the 1:1 ratio made mixing easy and error free. It went on easily and dried quickly so that I could apply 2 coats plus bottom paint In one day on a 46ft. Motor Yacht. The Sea Hawk Tropicoat was also easy to go on ( I recommend thinning as the paint is extremely heavy with copper). It dries quickly and have a hard service in 15 minutes. I am very happy with both products. – George M.
