Elakor-PU Lak Universal — polyurethane varnish-impregnation for concrete and wood
Colourless polyurethane varnish for impregnating concrete floors and screeds, priming under coloured floors and tinting with pigment paste.

This solvent-free primer with 100 % non-volatiles closes the pores of concrete, sand concrete, cement self-levelling floors, tile, stone and brick before epoxy and polyurethane coatings are applied. With sand it becomes a filler, and with sand and a special additive — a compound for skirtings and reveals. Adhesive strength to M750 concrete is 6.7 MPa with failure in concrete; the film withstands exposure to water and xylene for at least 48 hours.
