Foster 40-51 Mold Resistant Clear Coat has a low viscosity, which allows it to be easily applied by hand or with virtually any type of airless spray system.
It works well on a wide variety of surfaces: wood, painted surfaces, wall board, masonry surfaces, metal.
Foster 40-51 appears white when wet, but dries to a clear finish, allowing the original surface to be visible beneath the coating.
The inconspicuous nature of the finish offers benefits beyond simple aesthetics. Because the original condition of the surface is visible and not hidden behind a coating, industrial hygienists, consultants and building owners will be able to confirm that surfaces were clean prior to inspection. Ideal for a variety of applications: industrial, commercial, residential, hospitals, schools, food processing plants.
Over time, Foster 40-51 Sheer Defense will be highly resistant to staining caused by chemicals, mold or mildew. The formulation is based upon a durable acrylic polymer and contains blocking agents to help protect it from UV degradation. It also has excellent water resistance and will not blush once fully cured.

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 aesthetic appearance, apply product to a small test area prior to complete application. Not recommended for use on floors in high traffic areas.
Foster Sheer Defense (40-51) can be applied with virtually any type of airless spray equipment on the market today.
Reversible cleaning 0.015” to 0.017” spray tips are recommended for optimum application. Average viscosity range 1,200-1,800 cps.
