A polymer-modified, protein-free cementitious smoothing compound formulated for levelling uneven internal subfloors prior to installing decorative floor coverings. \u003cbr\u003e\u003cbr\u003eWhen mixed with approximately 4 litres of clean water, it produces a free-flowing slurry that rapidly finds its own level, eliminating ridges and hollows to create a uniform surface. The compound remains workable for 15-20 minutes at 20 °C and accepts light foot traffic within 2-4 hours, with most floor coverings suitable for installation after around 16 hours. \u003cbr\u003e\u003cbr\u003eIts protein-free composition prevents bacterial growth, ensuring suitability for hygiene-critical environments such as hospitals, food-processing zones, and commercial kitchens. \u003cbr\u003e\u003cbr\u003eDesigned exclusively for dry, internal use on concrete, sand\/cement screeds, stone, or firmly bonded unglazed ceramic tiles, it must always be overlaid with a decorative finish and is not suitable for calcium-sulphate screeds, adhesive residues, underfloor heating, or use as a wearing surface.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp;
