Moisture barrier (two layers necessary) up to a residual moisture content ≤ 5 CM % in the substrate of cement screeds, on underfloor heatings up to a residual moisture content ≤ 3 CM %.
For priming prior to the application of floor levellers/fairing coats and subsequently gluing parquet flooring.
For priming on substrates with residues of dispersion adhesive, reaction resin adhesive, water-soluble adhesive (e.g. sulphite liquor adhesives) and bituminous adhesive.
