GLIMS® PRO CRT-20 — thixotropic R2 mortar for non-structural repair
Thixotropic R2 mortar with fibre for filling voids, caulking joints, repairing manholes and tanks; compressive strength from 20 MPa at 28 days, W8.

TOP 450 is a corundum topping for the heaviest duty: open and closed warehouses, car parks, workshops, car service stations, production halls and retail areas. The cement-bound mix is trowelled into freshly laid concrete with power trowels, together with GLIMS Cure-A curing compound where necessary. Compressive strength after 28 days is at least 60 MPa, abrasion to GOST 13087 is 0.5 g/cm², service range −50…+120 °C.
