Environmentally friendly ablative contains the most effective concentration of copper-free biocide available, combined with slime-fighting zinc for superior antifouling protection against barnacles, mussels, slime, and weeds. Use on properly prepared aluminum, fiberglass, wood, or steel boats in fresh and salt water. Krypton is also ideal for outdrives, trim tabs, and other underwater metals.

High performance, copper-free, and safer for marine ecosystems

Krypton’s potent, copper-free, biodegradable biocide has cuprous oxide bottom paint’s power to defeat and shed bottom-hugging barnacles and zebra mussels bent on destruction – but it does so without harming the environment. For complete fouling protection, Krypton also contains a zinc biocide that effectively deters formation of algae and slime at and under your waterline. Your bottom stays cleaner, as do the waters beneath it. No foul, no harm.

Compatible with aluminum and underwater metals

Because there’s no copper in Krypton, it’s great for coating aluminum hulls and underwater metals like props and outdrives, without inducing galvanic corrosion. No copper also means a Krypton bottom coating weighs less and creates less work for the engine, so you shell out less for fuel.

Durable, stable, and colorful

There’s even more to like about Krypton aside from great antifouling protection. Tired of flat, lifeless-looking bottom paint? Krypton contains no copper so its five available colors are brighter, cleaner, and longer-lasting. If your boat sits idle for a period of time, unlike other antifoulings, Krypton doesn’t require scuffing to reactivate the antifouling agent before splashing the boat.

Frequently Asked Questions

Can this paint be used on aluminum and underwater metals?

Yes. Because there’s no copper in Krypton, it’s great for aluminum hulls and underwater metals like props and outdrives, without any risk of galvanic corrosion. Aluminum should be primed with TotalBoat Aluminum Boat Barrier Coat primer.

Is Krypton a multi-season or single-season antifouling paint?

For Krypton to provide multi-season protection, it generally needs 1 coat applied of paint per season, and in harsh climates and waters, sometimes more than 1 coat per season is necessary.

Can I use Krypton above the waterline?

No, Krypton is meant to be used below the waterline only. It does not contain UV resistance and is an ablative finish designed to wear away with use, constantly exposing fresh biocide.

Can this paint be used in freshwater?

Yes. You can use it on prepared aluminum, fiberglass, wood, iron, and steel in fresh, salt, and brackish waters.

Can TotalBoat Krypton be applied over other paints?

Yes, Krypton can be applied over nearly all existing bottom paints (aside from tin, vinyl or paints containing Teflon®), as long as they are in good condition. Remove any loose, flaking paint, sand with 80 grit, wipe the surface with TotalBoat Special Brushing Thinner 100, and apply paint. Paints in poor condition should be removed completely.

What primer do you recommend with Totalboat Krypton?

On unpainted gelcoat, use TotalBoat TotalProtect barrier coat and follow instructions. On a wooden boat, thin the first coat of Krypton on bare wood 5 to 10%. For aluminum, use TotalBoat Aluminum Boat Barrier Coat.

Can this paint be thinned?

TotalBoat Krypton should not require thinning, but if desired, it can be thinned with solvent up to 10% (12 oz. per gallon) with TotalBoat Special Brushing Thinner 100, or Xylene for spraying.

What is the best way to apply Krypton?

We strongly recommend a 3/16” nap or foam solvent-safe roller cover. For brushing, use a high-quality, natural bristle brush.

What is the coverage of this paint?

500 sq. ft. per gallon or 125 sq. ft. per quart at 2 mils wet.

How much paint do I need for my boat?

The best way to estimate how much paint you’ll need is to calculate the approximate surface area of the hull below the waterline, in square feet. Multiply boat length X beam X 0.85.

How soon after painting should I launch my boat?

Before launching, allow drying for the specified time based upon temperature: 2 hours at 90ºF, 4 hours at 70ºF, or 8 hours at 50ºF. There is no maximum amount of time that the boat can be launched after painting.

What is the dry time before launching?

Dry time to launch will be dependent on temperature: 2 hours at 90ºF, 4 hours at 70ºF, or 8 hours at 50ºF. There is no maximum time to launch. You can paint your boat with Krypton in the fall and launch in the spring.

Do boats painted with Krypton need to be repainted prior to launch once hauled?

No. Boats painted with Krypton can be hauled and launched with no loss of antifouling effectiveness.
