Sand & Cement Render
Before acrylic render there was cement render which is now considered old school. Builders who are meticulous in their finished product still prefer cement render as it will achieve 100% straightness. There are finishes that can only be achieved in cement render, for example oxide finish which gives a heritage look and that is mainly used in inner suburbs to match existing render when extending old houses.
Some of the finishes associated with cement render are stucco (rough cast) and oxide finish.
Application of Cement Render
To apply cement render successfully there are various additives that need to be used like waterproofing and adhesive chemicals. On old or smooth brickwork a splash coat with cement and best bond is required as cement render alone will not adhere properly to the surface. As cement render is a European technology it is best used with bessa blocks or cement blocks more commonly. Another crucial part of cement render is it requires a coat of sealer on the base coat before any acrylic texture can be applied to optimise water proofing and adhesion. If a coat of sealer is required anyway in certain circumstances one coat of sealer on top of the texture is sufficient.
