MuscleBlock Moisture Barrier, also known as “Original” or “MuscleBlock 2K”, is a 100% solids, two-component, high-performance epoxy primer uniquely formulated to effectively reduce moisture vapor emission rates (MVER) through a concrete slab to levels that allow subsequent installation of nonpermeable floor finishes. It is to be installed as a neat coating directly to properly prepared concrete substrates where moisture vapor drive is suspected or has been identified through testing procedures. MuscleBlock Moisture Barrier deeply penetrates and bonds into concrete slabs to help lock down moisture and prevent moisture vapor drive from causing blistering or delamination in the floor finish. It is the best primer for most polymer flooring systems, but can also be used to reduce MVER to levels that allow other floor finishes such as VCT, PVC sheet-goods, carpet tiles, rubber matting, etc. to be installed.

• 100% solids water clear
