Overview

Humidity Primer is a two-component water-based epoxy primer, used to prime and seal porous substrates including highly porous asphalt, concrete and wooden surfaces, prior to the application of Fibrecoat.

The Humidity Primer is made up of both resin & hardener; once both components are mixed the primer will change to a white liquid. Designed to seal any pores within the surface of the substrate, the Humidity primer is compatible with moisture contents on the concrete surface up to 6%.
