Sopro GD 749 primer reduces absorbency and evens out variable suction in substrate. It stabilizes friable surfaces, binds loose particles and improves adhesion. 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.
