Elakor-PTs Grunt — polyurethane-cement primer for Elakor-PTs systems

Floor primers

The primer is mandatory before laying the polyurethane-cement floors of the series and closes the pores of concrete and sand-concrete screeds of grade not lower than M350 in 1–2 coats. Substrate moisture, air humidity and dew point are not limited for it; the only requirement is the absence of puddles. According to the technical data sheet, the main layer is laid at +20 °C not earlier than 24 and not later than 36 hours afterwards; the coating itself is dark grey and semi-matt, fire hazard class KM2.
