Mastertop P 621 

Mastertop P 621 is a low viscosity, solvent free, two component epoxy resin based primer. It has a high tolerance to concrete with a damp surface.

Mastertop P 621 is designed for use as a primer on mineral substrates such as concrete and cementitious screeds. It is primarily intended for use in bridge deck waterprooing applications under torch applied bitumen sheet and including the applications to early age concrete.

It can also be used to other applications where the concrete suface is damp.
