Elakor-PU Grunt-2K/50 — two-component deep-penetrating primer
ELAKOR

Elakor-PU Grunt-2K/50 — two-component deep-penetrating primer

Floor primers

This primer of two components mixed 1:1 by volume is designed for dense low-porosity substrates: concrete of grade M350 and above, concrete tile, magnesia concrete, stone and slate. On concretes below M350 it works as a deep hardening impregnation, and the permissible substrate moisture is up to 6 % by weight, so it also suits damp but not wet concrete. The mix has a pot life of at least 90 minutes, the film elongates by at least 70 %, adhesion to concrete is 6.4 MPa; according to the technical data sheet, the material is approved for food and pharmaceutical plants.
