Material preparation 

• Stir well.
• Do not thin.
• Apply only to clean, dry surfaces.
• Ensure that all surfaces are free of all wax, grease, oil, dirt, rust, mold and other surface contaminants.
• Weathered wood substrates need to be sanded down to a sound surface.
• On painted surfaces, remove all flaking, loose or chalking material.
• Sand all glossy painted surfaces using 220-grit sandpaper to roughen the entire area.

Application

• Apply evenly to wooden surfaces at the rate of 250 – 450 sq. Ft./gal. (6.1 – 11.0 m2 /l) until a uniform film remains on the surface.
• It can be used at higher coverages on hard, non-porous surfaces of up to 600 sq. Ft./gal. (14.7 m2 /l) such as tile, metal or finished concrete.
• Spraying or brushing will give the smoothest surfaces.
• For optimum performance, maintain uniform recommended coverage.
• To assure the appearance meets expectations, apply product to a small test area prior to complete application.
