Comparison: National Pool Finishes VS Other Brands

How do National Pool Finishes Swimming Pool Paints measure up when compared with other brands? To answer that question and help you make a good decision when looking for a pool paint, we have compiled some information about some popular swimming pool paints.

1) How does National Pool Finishes Pool Guard EHB epoxy pool paint compare with Olympic Epoxy Coatings swimming pool paint?*

Both of these brands produce a high build epoxy pool paint that provide a long service life. Olympic ZERON should last up to 8 years and Olympic Poxolon II will last up to 5 years.  National Paint Industries says their Pool Guard EHB will last 10 years. When using Olympic Epoxy Coatings, you need a primer on most bare surfaces. National Paint Industries products are self priming on Gunite, Concrete, and Plaster. What about coverage? Pool Guard EHB swimming pool paint will cover about 250 sq.ft per Gallon. ZERON has a heavier body and covers 125 – 150 sq.ft per Gallon. Poxolon II covers about the same square footage as Pool Guard EHB.

2) How does National Pool Finishes Pool Shield CRX chlorinated rubber pool paint compare with Benjamin Moore’s INSL-X Chlorinated Rubber Based Pool Paint?**

This comparison is drawn between two similar type products: Chlorinated Rubber Pool Paint. When applying to bare surfaces neither coating requires a primer. Both are suitable for chlorinated or salt water pool systems. Which is more durable? Pool Shield CRX contains UV additives and Silicone that will help it withstand the sun’s rays for longer. INSL-X covers about 200 – 250 sq.ft. per Gallon whereas Pool Shield covers about 400 sq.ft. per Gallon. In addition the manufacturer recommends not thinning down the INSL-X. Pool Shield CRX rubber pool paint is available in over 90 colors and INSL-X offers only 6 color options.

3) How does National Pool Finishes AquaKote Water-based Acrylic pool paint compare with RAMUC DS Acrylic swimming pool paint?

Both National Pool Finishes and RAMUC manufacture a water based acrylic pool paint. Water based Acrylic swimming pool paints are ideal when the painting window is very short. It only needs a 3 day cure time. Also, both of these coatings can be applied to cool, damp surfaces without priming. Which offers the best value? The answer is up to you because they are so similar.

RAMUC has 7 color options. AquaKote has over 90. RAMUC offers slightly less coverage on previously painted surfaces: 350 – 400 sq.ft. AquaKote offers 400 sq.ft. per gallon (depending on the porosity of the surface.) How about price? Most online retailers offer DS Acrylic from $62.00 up to $90.00. The Bottom Paint Store has National Pool Finishes AquaKote  available for about 1/2 the cost and FREE SHIPPING.

PropOne Vs. PropGlide

It is widely accepted that a build up of marine life on the surface of a boat’s propeller and drive shaft negatively impacts engine efficiency and performance. Even if the prop has a thin layer of growth on it’s surface area, fuel efficiency is reduced by a significant amount. To counter this problem, engineers have turned to developing “super-slick” coatings. When the drive is engaged, and the prop begins to move, any organisms attempting to adhere to the prop simply slide right off! No chemicals are used to poison or kill the organisms in the environment.

How do PropOne* and PropGlide compare?

Which coating gives you the most bang for your buck?

PropGlide is much newer to the market than PropOne, but has been in development for over ten years. Being new to the slick coating market, PropGlide appears to be able to avoid slipping into the same ruts that their competitors have. The biggest obstacle for PropOne is the cost. Comparing the two products at price point, PropGlide is about 30% less expensive and offers 25% more product. That’s 2 strikes for PropOne right off the bat. PropOne is available in the following sizes: 1000mL, 500mL, and 250mL. On the other hand PropGlide offers a size larger than PropOne’s 1000mL and still manages a lower cost. Also PropGlide offers a size smaller than PropOne’s 250mL for sailboat owners who don’t need the larger quantities of product. (For more information on choosing the right size of PropGlide, see this Coverage Chart.)

In terms of performance, both slick coatings are equally good. They do the job and do it well. It is too early to say which product will outlast the other in the minds of consumers. But for right now, we recommend PropGlide as opposed to PropOne. The savings alone makes PropGlide worth every penny.





*PropOne was formerly known as PropGold. It is essentially the same product, just a different brand name.

Which Non-Antifouling Paint is Recommended for Wood?

sailboat-1149519_640Painting a wooden boat on your own can be a daunting task. The amount of information about the correct way to paint a boat is staggering! First time boat owners may be at a loss when trying to make a plan for their first project. The Bottom Paint Store’s aim is to make this process as stress-free as possible so you can enjoy working on your boat and ultimately, enjoy the fruits of your labor!

If you have a boat that sits in the water for long periods of time, but don’t have a problem with fouling in your area, you will need a durable topside boat paint that can be submerged. (Fouling refers to the buildup of slime, algae, barnacles, and other organisms that adhere to the hull of a boat.) To determine what paint is best for your boat, ask yourself these questions:

1. Will my wooden-hulled boat be submerged long-term?

Constant submersion will require a more durable, 2 part coating. The protection that a 2 part coating can provide is superior to almost all single stage paints. Primer is also very important. It provides a surface for the paint to bond with and it also protects the wood from water seepage. Here are 2 good options:

150-epoxy-primerRecommended Primer: Supermarine Formula 150 Epoxy Primer (SM-7390) Sand the Bare Wood Hull smooth with 80 grit sandpaper. For the 1st coat of primer, thin the primer down 10-15% with MEK and apply to the bare wood. This increases the absorption of the primer into the wood, and locks out the air and moisture. Apply the 2nd coat of primer without thinning. Apply your choice of 2 part topcoat.

 Recommended Paint Option 1: Supreme Urethane (SM-266) The most durable, “rough and tough” coating. Ironside can be brushed, sprayed, or rolled. Unless you are experienced with spray equipment the best way for the “do-it-yourself-er” to apply it is the “roll and tip” method. Traditionally, one person rolls a thin coat of paint onto the prepared surface while a second person follows the roller with a brush. Using just the tip of the brush, smooth out the coating in long sweeping strokes. Tipping removes bubbles created by the roller. Supreme Urethane PaintThis product sets up quickly so speedy application and proper thinning will help prevent brush or roller drag. Spraying offers the best film thickness control, however, rolling is often the best way to achieve the recommended maximum Wet Film Thickness which is 4 mils. The recommended DFT (Dry Film Thickness) is 4 mils minimum. Applications applied too thickly may not adhere or level properly, run, sag take longer to cure or result in unwanted amber resin color. Always adhere to the manufacturers recommended WFT and DFT (Dry Film Thickness) for best results. Theoretical coverage is 300 sq.ft/GL. Ironside has a mixing ratio of 7:1 with a 10 minute induction time. Be very careful to mix the paint correctly to avoid problems with curing. Apply 2 or 3 coats to the hull. For best results, recoat within 4 hours or after 24 hours. Sand between coats after 48 hours have elapsed. Recommended minimum cure time is 5 days under most conditions.

2-part-epoxyRecommended Paint Option 2: Supermarine 2 Part Epoxy (SM-6000) – the Supermarine workhorse product. 2 Part Epoxy is a polyester-epoxy, high performance, two component, catalyst-cured coating with excellent chemical resistance and hardness. 2 Part Epoxy comes in a 2 Gallon Kit. Simply combine 1 GL of Part A with Part B in equal amounts for a total of 2 GL’s usable product. Let stand for 30 minutes before applying. Mix only enough for each day’s use.  Thinning is not typically required. Use only with factory recommended thinner, SM-605 Thinner. One gallon covers 300 square feet. Dry to the touch in one hour, tack free in 8 hours, recoat in 24 hours. Pot life is 8 hours @ 70 degrees F. The manufacturer recommends applying two or more coats to achieve a minimum DFT of 4 mils.

2. Will my wooden-hulled boat be hauled out after use?

If the boat will be hauled out after use then a 2 part epoxy coating is not absolutely necessary. A less expensive epoxy coating can be used and the wooden hull will still have protection.

Recommended Primer: Supermarine Etching Primer (SM-664) This primer creates a virtually unbreakable chemical bond to whatever it has been applied to which allows it to be used almost anywhere and most any application! Sand the Bare Wood Hull smooth with 80 grit sandpaper. For the 1st coat of primer, thin the primer down 10-15% with SM-605 Synthetic Thinner and apply to Esthing Primer 664Dthe bare wood. Etching Primer will fill the grain of the wood and create a smooth easy to adhere to surface for the paint. It has an unusually high amount of solid material, sands beautifully and locks our air and moisture. Apply the 2nd coat of primer without thinning. Dries to the touch in 30 minutes, tack free in 1 hour, recoatable in 2 hours, dries hard in 4 hours. Recommend waiting until 4 hours have passed before recoating with primer or paint. Coverage is approximately 250 sq.ft/GL, depending on the texture and porosity of the surface. Apply by brush, roller or spray. Next, Apply your choice of 1 part Epoxy topcoat.

Recommended Paint: Mono-Epoxy Paint Single stage epoxy formula – less hassle than a 2 part epoxy. Mono-Epoxy is highly water-resistant, resistant to chalking, fading & chipping, resists peeling & cracking, weather-resistant, submersible long term. Recommended DFT: 5 mils. Coverage is approximately 250-300 sq. ft. per gallon @ 3 mils wet. For best results recoat within 24-48 hours or sand between applications. Allow top coat film to cure thoroughly before allowing it to enter full service duty. The recommended minimum cure time is 5-7 days under most conditions. DO NOT allow newly applied paint to get wet for a minimum of 48 hours. The dry cured film may be wet sanded and buffed to remove runs and blemishes. See the Mono-Epoxy product data page for more application tips.

Note: Both Supreme Urethane (SM-266) and Supermarine 2 Part Epoxy (SM-6000) are compatible with Etching Primer (SM-664). If your boat will not be in the water constantly and you would still like top of the line performance, you can apply a 2 part primer and a 2 part Epoxy Topcoat. There are no hard and fast rules for painting your own boat. That being said, you could also apply a single stage primer like SM-664 and go with a durable 2 part topcoat. Just be sure to follow all manufacturer recommendations for priming, mixing, and thinning to avoid problems with curing.

3. Does the wood hull have a coating on it now?

If the wood hull has a coating on it currently, the suggestions for Question 2 should be followed. There will a few different steps in the prep stage of the project, but everything else will be the same.

Prep: Sand the existing coating with 80-120 grit sandpaper. Wipe down with a clean tack rag. All surfaces must be thoroughly clean and dry before the application of any primer. You don’t have to totally remove all the previous coating. Just try to get rid of all loose paint and be sure that the surface is sound.

Recommended Primer: Etching Primer (SM-664) When applying primer, do not thin it down like you would for bare wood surfaces unless you are spray applying. Some thinner may be used to run the primer through the spray gun. Apply a minimum of 2 coats of primer. Etching Primer should be allowed to dry a minimum of two to three hours before recoating with subsequent primers or marine finish coatings. It should be applied to a dry film thickness between 0.3-0.5 mil.

Recommended Paint: Mono-Epoxy or similar coating listed here. Follow all manufacturer guidelines for each product.

Other Paint Products for Single Day Use

Here are some other products that are not recommended for long-term submersion but can be applied to wood-hulled boats. These products are much less expensive, but are also not as durable and long-lasting as the products mentioned above.

Fairing is process of smoothing out and restoring the damaged surface of the hull. A fairing compound such as Epoxy resin can be used to fill in divots or gouges and then be sanded to a smooth finish. This restores the surface to its original shape and also prepares it for painting.

Note: Before attempting a repair by yourself, get a professional opinion. Always wears Personal Protective Equipment when sanding or working with chemical compounds!

Here are some guidelines to fairing out imperfections in your hull:

  1. Sand all loose surface debris and hard edges.f5-filler-large-may-2014
  2. Rid surface of debris with clean cloth.
  3. Wet out surface with Hawk Epoxy.
  4. Mix another batch of Hawk Epoxy with F5 Light Density Filler and apply to repair area.
  5. Use long strokes to spread out filler compound over the damaged hull. Apply until the mixture is slightly raised above the hull surface. Make sure the compound extends beyond the repair area.
  6. Let cure 6 hours.
  7. Add skim coat of F5 Filler / Epoxy compound to achieve a very smooth surface. Let cure.
  8. Sand the repair to the desired shape with 80 grit sandpaper.

Which Bottom Paint is Best for Freshwater Lakes?

algaeMost Antifouling Bottom Paint is marketed toward the harsh conditions of the Caribbean. But which Antifouling Bottom Paint will work best in Freshwater Lakes?

The short answer is this: Antifouling Bottom Paint that works well in the harsh conditions of the Caribbean will be more than enough protection for boats in freshwater lakes. The real trick is choosing the paint that will fit your situation the best. Choosing a bottom paint with more biocide (usually cuprous oxide) will be more potent and fight off growth more successfully. Sometimes you don’t need to purchase the strongest and the greatest. A paint with just the right amount of biocide will do nicely and can also save a few bucks.

Here are some basic guidelines to help you decide which paint is best for your boat.

boat-trailer-360If the boat comes out of the water periodically, such as on a lift or trailer, Ablative Bottom Paint is the correct choice. Cukote is a very popular and potent Sea Hawk Ablative Paint. Also check out, Sea Hawk’s AF-33 and Blue Water Marine’s New England Copper.

If the boat never comes out of the water except to be repainted, a Hard Epoxy Bottom Paint will keep away the algae. Sea Hawk Sharkskin is a mid strength Hard Bottom Paint. Though there are stronger paints too; Sea Hawk Tropikote, and Pettit Trinidad. Copper Shield 35 Hard is a great Hard bottom paint that fits a tighter budget.

What about Bottom Paint Additives?

Sea Hawk produces a paint additive called Bio Cop TF to help fight against algae and soft growth. This product will boost the effectiveness of your paint’s ability to keep the hull free of growth. **NOTE: Biocop TF Pint may only be used as a bottom paint additive in the following products: AF-33, Cukote, Sharkskin, Talon, and Tropikote.

Can Aluma Hawk Paint be used with Tuff Stuff Epoxy Primer?

The direct answer is Yes.

Sea Hawk Tuff Stuff Epoxy Primeraluma-hawk-boat-paint-by-sea-hawk-paints-28288-1000x1078 is an effective water barrier and universal primer. When applied to metal hulled boats it can serve as corrosion protection below the waterline. Therefore many boaters want to have that sort of protection on their Jon boat, and apply Aluma Hawk Boat Paint on top.

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 have a direct impact on dry times. QUICK and EASY RULE: When the coating is dry to the touch, yet still has some tack, it is ready to be over coated. Your thumb will leave a print without lifting any epoxy. This is called hot-coating. However, if the coating is completely cured (or after 24 hours) it needs to be thoroughly sanded with 80 grit sand paper to remove the shine, or you must apply another coat of Tuff Stuff within 6 days. Then you have an additional 24 hour maximum window to overcoat with paint.

Tuff Stuff Marine Epoxy Primer

These two products are great on their own, but they can do so much more when working in conjunction with each other.
