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

Epolast is poured in a single layer over Epoksol-2MS epoxy primer and spread with a notched trowel or squeegee, followed by rolling with a spiked roller. The compound is odourless, retains high chemical and abrasion resistance even at elevated humidity and withstands water, petrol, 40 % NaOH, 10 % sulphuric and 37 % hydrochloric acid for at least 72 h. It can be laid on concrete as well as on rigid metal and timber structures; service properties develop within 10 days.
