High Build is a 100% Acrylic Render, filled with lightweight insulating aggregates. The product is used in place of traditional sand/cement render for the levelling of flush jointed block work, Hebel® and raked brick prior to the application of an acrylic texture. The product can be applied at a thickness of up to 15 mm in one single application without the normal shrinkage cracks and soft corners associated with traditional sand and cement renders.
