Smith’s Poly-FLEX is a Heavy-Duty, 2-Component, Moisture Tolerant, Semi-Rigid Polyurethane Flowable Resurfacing Compound with good elongation characteristics to aid in suppressing minor cracks from telegraphing through yet rigid enough for traditional applications. Walkable in roughly 2 ½ hours and accepts subsequent layers/systems in as little as 4 hours.  Applies from a minimum of 30 mils up to 5 inches in a single lift.  Tenaciously bonds to a variety of substrates.

Smith’s Poly-FLEX is freeze/thaw stable allowing for use as a base for interior and exterior resinous or cement overlay (with a sand broadcast) systems.  Also suitable over radiant floor heating systems.  Smith’s Poly-FLEX suppresses up to 15 lbs. (ASTM F-1869) or 90% RH (ASTM F-2170) of osmotic moisture vapor transmission with up to 14 pH on concrete slabs when properly mechanically prepared.
