How is it used?

When hand mixing it should be mixed with clean tap water (6-7 litres per bag) using an electric whisk to a smooth creamy consistency and applied by hand with a steel trowel. Each backing coat must be a minimum of 10mm and should be applied at a minimum of 20mm ( 2 x 10mm coats) for sulphate and chloride contamination or 30mm (2 x 15mm coats) for nitrate contamination.
Baumit StarTex mesh should be incorporated into the outer third of the base coat if the substrate is damp or made of dissimilar materials and the base coat should be finished with a plasterers comb or stiff brush to create a suitable key for decorative topcoat renders.
