BIRSS Overlak / Overlak semi-matt — epoxy floor sealer
This solvent-free finishing varnish seals Akvapol and Multipol epoxy systems, floors with decorative chips or bare concrete. It comes in two versions — colourless gloss and semi-matt — and the resulting surface is wear-resistant and non-slip. The varnish resists neutral salt solutions and fuels and lubricants, bond to concrete is at least 2 MPa; owing to its limited UV resistance it is used indoors only.
