RH-100
MOISTURE VAPOR REDUCER

A 100% solids epoxy coating specially formulated for interior use over concrete with high moisture and/or pH levels.

USG Durock™ Brand RH-100™ Moisture Vapor Reducer manages moisture and alkalinity in concrete subfloors from negatively affecting underlayments and floor coverings for interior use.

Features and Benefits

USG Durock™ Brand RH-100™ Moisture Vapor Reducer is formulated for use on new or existing concrete slabs with up to 100% relative humidity by reducing vapor transmission to acceptable levels prior to the installation of an approved underlayment system.  USG Durock RH-100 Moisture Vapor Reducer:

  • Reduces the inherent alkalinity in high-moisture areas that can effectively break down your flooring adhesives and lead to failure
  • Has low viscosity, which promotes superior penetration and adhesion
  • Has a moisture tolerant formulation that makes it suitable for concrete subfloors up to 100% RH
