STAUF - EHS 265 HYDRO-SEAL EPOXY PRIMER, 2.5 GALLON

Supplier SKU: EHS-265-2G60
East Bay Supply SKU: STFEHS2652G

STAUF EHS-265 Hydro-Seal is a two-component, hybrid-epoxy resin based primer for subfloor preparation prior to installation of urethane-based leveling compounds. Unlike water or urethane-based primer, EHS-265 is not affected by elevated subfloor moisture. It will not foam up or get weaker because of water present in the subfloor. It also has a higher penetration of the concrete compared to traditional 100% solid epoxies which creates a stronger bond. It does however NOT create a moisture barrier but merely reduces the amount of vapor penetration.
