KRASKO

Tistrom — wear-resistant polyurethane varnish for concrete

Sealers and topcoats

Tistrom cures with air moisture and forms a gloss amber film that protects concrete from spalling and thermal cracking. The varnish is resistant to petrol, oils, petroleum products and alkalis and has high impact resistance; wear per ASTM D 4060 is 70 mg. It is used to coat floors in garages, car services, car parks and warehouses, as well as paving slabs, setts, stone and thin-layer polymer floors; service range −50…+100 °C.
