Pettit Protect White High Build Epoxy Barrier Primer Coat

Pettit Protect White High Build Epoxy Barrier Primer Coat

Pettit Protect Epoxy Primer is a heavy-duty, dual component epoxy coating best used where maximum resistance to fresh or salt water is a necessity. By reducing water absorption in fiberglass hulls, it’s an excellent choice for the prevention of osmotic blisters. Pettit Protect’s high-solids formula allows for a speedy application by requiring fewer coats for effective hull protection. An additional application of Pettit Protect Epoxy Primer is providing dependable corrosion protection on steel, aluminum, and any other underwater metals. It is perfectly suited for both commercial and pleasure craft applications and is engineered for excellent durability. Pettit Protect has renowned durability in exterior exposures. However, as with most epoxies, it will chalk if there isn’t a proper top coating.

 Features:

• Reduces water absorption in fiberglass hulls and prevents osmotic blistering.
• High film build for maximum protection with fewer coats.
• Excellent water and chemical resistance.
• Exceptional protection for steel, aluminum, and other metals.
• High Performance System for Underwater Running Gear.

Why Pettit Protect?

Pettit Protect utilizes Mica Shield Technology. Pettit Protect Mica is incorporated into the epoxy resin while in sheet form, where as other competitors use Mica in a ground form. The differences between the types of mica used in epoxy primers is the ratio of the mica particle length to its width. Pettit Protect uses a high aspect ratio mica whereas other competitors use a low aspect ratio mica. The sheets with high aspect ratio Mica are forced to overlay each other creating an impenetrable layer of epoxy. 

Pettit Protect high-solids formula saves time and money because it allows for quicker and easier application with fewer coats necessary for effective protection. When compared to competitive products, Pettit Protect’s high-build formula allows for application of heavier coats without it running or sagging while still providing a smooth finish for antifouling paint. Pettit Protect uses less solvent than competition and this reduces solvent smell. Together this results in less labor and less product needed to obtain the Dry Film Thickness (DFT) necessary for the ultimate in protection.

Frequently Asked Questions

What is Pettit Protect White High Build Epoxy Barrier Primer Coat used for?

Pettit Protect White High Build Epoxy Barrier Primer Coat is a two-part, high-solids epoxy coating designed to provide water and chemical resistance. It is used on fiberglass hulls to reduce water absorption and help prevent osmotic blistering, as well as on steel, aluminum, and other underwater metals for corrosion protection.

Can Pettit Protect epoxy primer be used on fiberglass hulls?

Yes. Pettit Protect can be applied to bare fiberglass hulls after thorough cleaning, de-waxing, and surface preparation. Depending on the application system, it can be used as a one-coat, no-sand priming system or applied in a minimum of two coats over sanded fiberglass. Follow the specified preparation and drying instructions for the selected system.

Is Pettit Protect suitable for aluminum and steel surfaces?

Yes. Pettit Protect is specified for bare aluminum and steel surfaces. Bare aluminum should be sandblasted or disc sanded to clean, bright metal before applying Pettit 6455 Metal Primer, while bare steel requires appropriate surface preparation and either direct application of Pettit Protect or use of Pettit 6980 Rustlok Steel Primer first.

How do you mix and apply Pettit Protect epoxy primer?

Mix 3 parts Part A with 1 part Part B by volume and stir thoroughly. Pettit Protect can be applied by brush, roller, airless spray, or conventional spray. An induction period of 15 minutes at 70°F is specified. Thinning is generally not required, but up to 10% Pettit 97 Epoxy Thinner may be used when needed to ease application in adverse weather conditions.

How many coats of Pettit Protect should be applied?

The standard application calls for a minimum of three coats, with a dry film thickness of 4 mils per coat. Specific systems can differ: for example, one coat may be used on properly prepared bare fiberglass as a no-sand priming system, while severely blistered fiberglass calls for three coats. Follow the applicable surface-preparation and coating instructions.

What are the application temperature and drying requirements for Pettit Protect?

Pettit Protect should be applied between 50°F and 90°F. At 70°F, the specified recoat window is 3 hours to 14 days, with a minimum launch time of 72 hours and 5-8 hours before applying bottom paint. If the maximum recoat interval is exceeded, the surface must be thoroughly sanded with 80 grit sandpaper before recoating or applying bottom paint.
