Product Features

EP 72 is a moisture tolerant epoxy primer. It can be used in new and old buildings as a primer, scratch coat, or levelling mortar. It has a medium viscosity and is formulated to penetrate the substrate to give a high strength base for subsequent coatings.

It increases the adhesive tensile strength on substrates with inadequate strength.

We strongly recommend that EP 72 be the starting point of our systems if moisture or vapour pressure is present in the substrate.

Furthermore EP72 can be applied to damp or wet surfaces (but not standing water) to displace water resulting in an excellent bond.
