Germoteks — polyurethane sealant for concrete floor joints
Elastic two-component polyurethane sealant for movement joints, cracks and junctions in floors; elongation at break 75 %.

Polibetol-Grunt cures with air moisture and serves as an intermediate coat under Polibetol-2 “COMFORT”, Polibetol and Polibetol-Ultra enamels. It seals pores, dustproofs concrete and improves adhesion of the finish coat, and when left uncovered it works as a strengthening coating. It has almost no odour, so priming is done without stopping production; application is possible at −5 °C, and the finish coat goes on after one day.
