Elakor-PU Grunt-2K/40 — maximum-depth polyurethane impregnation
Two-component polyurethane primer with 40 % solids content for hardening weak and porous concretes under polymer floors.

This thixotropic binder with increased UV resistance bonds quartz sand, pebbles, gravel, granite and marble screenings into a “stone carpet” for paths, paved areas, decorative coatings and products. For large volumes the adhesive is mixed with the filler in a concrete mixer and spread over the substrate immediately. The substrate is concrete or sand-cement screed of at least M200, at least 28 days old, primed with “Elakor-ED” epoxy primer; permissible working temperature from +5 to +22 °C, fire hazard class KM2.
