BIRSS 59 S1 M600 Moroz — flowable R4 mix for repairing pavements in frost
Non-shrink flowable mortar for roads, airfields, bridges, floors and equipment foundations, placed from −15 to +5 °C.

Grunt P prepares concrete substrates and cement-sand screeds for pouring self-levelling cement and polymer-cement floors. The compound contains no solvents and can be used indoors and outdoors at +5…+35 °C. The primer dries to degree 3 in no more than 1 h, and the self-levelling layer is laid after 12 h; it is supplied in 10 l polyethylene canisters.
