Germoteks — polyurethane sealant for concrete floor joints

Other floor materials

Germoteks fills movement joints, cracks and junctions in concrete floors and slabs, including those exposed to vibration and deformation; it is also used to repair joints in road surfaces and bridges. The compound is poured or applied with a gun, and porous substrates are first primed with PS-Grunt. The sealant is resistant to oils, petrol, metalworking fluids and alkalis and shows minimal shrinkage; relative elongation 75 %, adhesive strength 1.5 MPa.
