LEVL Top Corund — corundum topping for heavily loaded floors
Hardening dry mix with corundum for concrete floors under very significant mechanical loads; compressive strength at least 90 MPa.

Porous dusting concrete is strengthened with LEVL Coat 111 two-component epoxy impregnation. It is used as a stand-alone hardening system or as substrate preparation under polymer coatings: after curing it can be primed with epoxy, polyurethane and acrylate compounds. The impregnation is applied with a roller, brush or smooth trowel until saturation, allowing 6–12 hours between coats. Adhesion to concrete is over 4.0 MPa; abrasion (wear) of M300 concrete after treatment no more than 0.55 g/cm².
