Field Of Application
Sopro GD 749 primer reduces absorbency and evens out variable suction in substrates. It stabilises friable surfaces and binds loose particles. Sopro GD 749 improves adhesion. Sopro GD 749 prevents bubbling where overcoated by surface fillers and waterproof membranes; premature water loss is prevented where thin-bed tile adhesives and waterproof membranes are subsequently applied.
Suitable Substrates
Absorbent substrates such as cement render, lime/cement render, gypsum plaster, renders made from masonry cement, masonry, concrete, aerated concrete, paperless gypsum panels, gypsum plasterboard and gypsum fibreboard, cement screeds, calcium sulphate screeds, magnesium oxychloride (magnesite) screeds.
Yield
100 – 200 g/m² depending on substrate absorption.
Tools/Cleaning
Lambswool roller, foam roller, brush, block brush. Once dried, the primer is difficult to remove, thus care should be taken to clean tools quickly before the primer dries. Wash tools with water immediately after use.
Packaging: 25kg, 10kg, or 5kg canisters and 1kg bottle.
