Elakor-PU Grunt-2K/50 — two-component deep-penetrating primer
Two-component polyurethane primer for dense concretes, magnesia floors and substrates with a moisture content of up to 6 %.

This coating of specified hardness — Shore D from 35 to 45 — is designed for impacts and vibration, so it is used in sports halls, at stadiums and outdoor sports grounds, in medical institutions, industrial premises with vibration loads, and on the floors of vans and trailers. The substrate may be rubber crumb, concrete, sand concrete, wood or metal. Elongation at break is 60 %, compressive strength 42 MPa, fire hazard class KM2.
