What are acceptable levels of relative humidity?


The type of flooring product to be installed determines the acceptable level of relative humidity. Different RH specifications apply to different materials such as adhesive, resilient flooring, wood, or epoxy coatings.

RH Threshold is a term that refers to amount of RH a concrete slab must be at before flooring is laid. Check with the floor-covering installation guide for a relative humidity specification.
