APF VaporSolve LP | 99% RH Moisture Mitigation Epoxy APF VaporSolve LP (Low Perm) is a specialized, 100% solids epoxy coating engineered to isolate moisture-sensitive flooring systems from concrete with high moisture levels. It acts as a high-performance moisture mitigation layer, designed to prevent the devastating flooring failures caused by excessive moisture vapor transmission through the slab. VaporSolve LP is suitable for concrete substrates showing up to 99% Relative Humidity (RH) when measured in accordance with ASTM F2170. It is part of the proven APF VaporSolve system, formulated for low viscosity and superior substrate wetting to promote deep penetration and a permanent bond, even to damp concrete.
