    Field of Application

    Sopro GD 749 primer reduces absorbency and evens out variable suction in the substrate. It stabilizes friable surfaces, binds loose particles and improves adhesion. Sopro GD 749 primer prevents pin-holes when self-levelling compounds are used thus premature water loss is prevented where thin-bed tile adhesives are subsequently applied.


    Suitable Substrates

    Absorbent substrates such as cement render, lime/cement render, gypsum plaster, renders made from masonry cement, concrete, aerated concrete, paperless gypsum panels, gypsum plasterboard and gypsum fibreboard, cement screeds, calcium sulphate-based screeds, magnesium oxychloride (magnesite) screeds.
