PRODUCT DESCRIPTION

Pettit Protect Gray High Build Epoxy Barrier Primer Coat

Pettit Protect High Build Epoxy Primer is a heavy duty, two component epoxy coating for use where maximum resistance to fresh or salt water is required. It reduces water absorption in fiberglass hulls, making it an excellent choice for the prevention and repair of osmotic blisters. Pettit Protect’s high-solids formula allows for quicker and easier application with fewer coats necessary for effective protection. Pettit Protect also provides dependable corrosion protection on steel, aluminum, and all other underwater metals. It is ideally suited for commercial and pleasure craft applications and has excellent durability. Pettit Protect has excellent durability in exterior exposures, although, like most epoxies, it will chalk if not top coated.

 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.

Specifications:

  • Finish: Low luster
  • Coverage: 225 sq. ft/gal. with 3/8" nap roller
  • Mix Ratio (A/B): 3 to 1 (by volume)
  • VOC: 340 grams/liter - Parts A & B

Associated Products:

Pettit Epoxy Thinner: Thinning is not usually needed, but for slow drying in hot weather or windy conditions, small amounts may be added.

 Pettit Brushing Thinner: For cleaning the surface during preparation.

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.


How To Apply Pettit Protect Epoxy Primer

Pettit Protect can be easily applied by brush, roller, or spray. Use a high quality bristle brush or 3/8" nap roller made for epoxy paints. Thinning is generally not required, but in adverse weather conditions, Pettit Protect may be thinned up to 10% with Pettit 97 Epoxy Thinner to ease application. Stir or shake contents thoroughly to remix any settled material. Mix 3 parts Part A with 1 part Part B by volume and stir thoroughly.
