SHARKSKIN ADHESION PRIMER 3.70L

Surface preparation:

All Surfaces

Surface preparation is important. All surfaces must be smooth, clean, dry, and free of mildew, grease, soap film, sanding dust, or other contaminants. Remove all loose or peeling material from previously painted surfaces. Wash all surfaces with a solution of 3 tablespoons of phosphate-free TSP in a gallon of warm water. Rinse thoroughly, allow to dry, and then scuff sand using 80–120 grit sandpaper on a hand sander. Remove all sanding dust. Do not apply at temperatures below 10°C (50°F).

WARNING! If you scrape, sand, or remove old lead paint from any surface, you may release lead dust. LEAD IS TOXIC. Exposure to lead dust can cause serious illness, such as brain damage, especially in children. Pregnant women should also avoid exposure. Wear a NIOSH-approved respirator to control lead exposure. Carefully clean up with a wet mop or HEPA vacuum.

General Preparation & Application Tips for Decks

Painting your wood deck can be one of the most challenging painting projects around the home. Construction lumber is an unstable substrate at the best of times. When laid parallel to the ground, with extreme hot and cold exposure on the top surface and high moisture generation on the bottom side, proper preparation becomes critical. Deck coatings must withstand the sun’s intense UV radiation, ponding water, ice, salt, hot tub chemicals, abrasive grit, snow shovels and scrapers, high-pressure washers, mildew, and algae growth. All of this protection is demanded from only a few thousandths of an inch of coating thickness.

Surface Preparation for Existing Decks

• Existing decks must be thoroughly cleaned prior to repainting. Mildew and algae must be cleaned and neutralized using a solution of 1 part bleach to 4 parts water. This solution must remain in contact with the mildew or algae for at least 15 minutes, then be rinsed. Protect plants and water sources.
• Loose or popping nail heads should be pulled and replaced with galvanized nails of a larger size. Nail or screw heads should be countersunk to prevent tripping hazards. Fill all nail heads with a suitable exterior filler. All cracks, checks, or gaps where moisture could penetrate into the lumber should be filled with a caulking material.

Important Notes

• Sharkskin Elastomeric Primer/Sealer does not stop rot. The intended use of this product is to prolong the life of existing structures.
• Severely damaged or decaying surfaces should be replaced prior to applying a coating system.
• This product does not increase the adhesion of existing coatings to the substrate.

General Deck Preparation Tips

• Stay tuned to short- and long-term weather forecasts. Do not apply stain in direct sunlight or within 6 hours before or after rainfall. Surface temperatures of the wood should be below 35°C (95°F).
• Application conditions should be between 10–30°C (50°–86°F). Apply using a synthetic brush and a 10–20mm (3/8–3/4") roller sleeve, maintaining full, even coats and a consistent wet edge.
• Purchase enough stain to complete the entire project. If disposal is necessary, give leftover product to someone who can use it, or contact your municipality or visit www.productcare.org for recycling options in your area.
