Cement Render is a combination of sand, cement and clay or lime. Cement render can be applied to brick, cement, stone and painted walls (undercoat must be applied first so render does not fall off) when going onto painted walls. In cases where render is to go onto painted walls acrylic render is recommended over traditional cement render.
Cement render is a great option for rendering your home, even though acrylic render materials are being used more often then ever before.

With that being said although decreasing in popularity some people do decide to go with a cement render and oxide finish.
This applied on your cement render after about a month, it is longer lasting and 20 times thicker than paint giving it durability. Coloured acrylic render comes in every single colour your paint comes in and a lot of different textures.

Coloured Acrylic Render cannot be applied directly to a wall without an undercoat.
