Cement Additives iscosa

RT Polymer is a chemical additive that ensures that colour pigment is uniform across the tile, yielding brighter colours. The product is a specially formulated co-polymer that induces plasticity into the cementitious mix, accelerates the hydration of the cement and sequesters the soluble salts that cause efflorescence and scumming on the tile surface.
