LEVL Top Cor — corundum topping for concrete floors
Dry hardening mix with corundum and quartz sand for workshops, warehouses and car parks; compressive strength at least 80 MPa.

LEVL Coat 103 epoxy primer is used to treat concrete and other mineral substrates before LEVL epoxy and polyurethane floors are laid. It is applied with a flat trowel crosswise in two coats, if necessary filled 1:1 with quartz sand and broadcast. With sand the material becomes a filler and a compound for skirtings and coves, and neat it is used to inject voids in concrete. Adhesion to concrete is at least 2.5 MPa, substrate moisture no more than 5 %, shelf life 18 months.
