GENERAL DESCRIPTION

 

Pruett-Schaffer’s #50-13344-1  is an air drying, solvent based, oil modified asphaltic varnish.  It may be applied by brush, spray or roller.  It exhibits good surface wetting properties for difficult to clean substrates and corrosion & water resistance. It provides a cost effective alternative to toxic coal tar based compounds for protecting steel , aluminum or concrete from normal environmental conditions.

 

RECOMMENDED USES

 

This product is recommended for general maintenance on steel or concrete structures wherever normal interior or exterior atmospheric conditions exist. It is designed for use as a corrosion preventative & waterproofing compound over concrete & metal substrates, both above & below grade, exposed to humidity, salt water, oil, weak acids & alkali. The coating is not normally topcoated & is not recommended for exposure to solvents, gasoline or other fuels. This formula complies in raw materials specifications & coating performance to Military Specification TT-V-51f.

 

 

 

SURFACE PREPARATION

For best performance, new metal substrates should be clean, dry, & free of oil/grease. Concrete should have all form release oils, curing membranes & dirt removed. This coating is very tolerant of

less than perfect surface preparation. Feather all rough or sharp edges.

 

THINNING

 

Under normal conditions no thinning is necessary.  Adding thinner to this product will cause the product to be non-voc compliant by state law.

 

APPLICATION EQUIPMENT
