Smith’s SKM is a 2-Component, Fast Setting, Moisture Tolerant, 100% Solids Polyurethane Light Gray Skim-Coat and Patching compound with good elongation to aid in suppressing minor cracks from telegraphing through yet rigid enough for traditional substrate surface repairs. Walkable in roughly 2 ½ hours to accept subsequent layers/systems as well as sanding with an orbital floor machine. Smith’s SKM contains no sand, applies from a feather edge (0”) to 5” in a single lift and may be extended with an appropriate dry aggregate such as pea stone or quartz sand if desired in deeper fill applications. Sold as a light grey but may be tinted with Smith’s ISC Industrial Solid Color Packs (white is not attainable with Smith’s SKM).
For use interior or exterior under most resinous coatings or polymer modified cementitious overlays, to include but not limited to Smith’s CPR products in thermal shock environments.
