TRUBUILD PRIMESURE EPMI is a two-component, epoxy-based, solvent-free and moisture-insensitive primer developed to improve adhesion and surface preparation before applying advanced waterproofing systems. It is specifically designed as a primer for PU, polyurea and PU hybrid waterproofing coatings, creating a strong bond between the substrate and the waterproofing membrane.

Its low-viscosity formulation allows deep penetration into concrete pores, helping strengthen the interface and improve coating performance. The product is formulated to tolerate substrate moisture levels up to 5%, reducing the risk of adhesion failures caused by residual moisture.

TRUBUILD PRIMESURE EPMI is designed for easy on-site application through brush or roller, offering good brushability and uniform substrate coverage. Since it is solvent-free, it supports cleaner application while maintaining excellent mechanical bonding characteristics.

This primer is recommended wherever long-term waterproofing durability depends on strong substrate bonding and proper surface conditioning, particularly on prepared concrete surfaces before PU-based coating systems.
