This produces a light gray block with a fine surface texture and a high compressive strength. A
Cement render Wikipedia
Cement render consists of 6 parts clean sharp fine sand, 1 part cement, and 1 part lime. The lime makes the render more workable and reduces cracking when the render dries. Any general purpose cement can be used. Various additives can be added to the mix to increase adhesion. Coarser sand is used in the base layer and slightly finer sand in the
