Epoxy sealer for concrete floors

GEMCOAT EFS is low viscosity, two pot epoxy sealer for porous substrates such as concrete floors. It is formulated at low viscosity to allow penetration into porous surfaces. GEMCOAT EFS can then be overcoated with GEMCOAT EFC epoxy floor coating. It has low temperature cure and will tolerate damp surfaces and less than perfect surface preparation. It can be used for waterproofing concrete and is suitable for total immersion. It can be used for bonding new concrete to old concrete.
