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 applying 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 than ever before. Cement render has been used for so long and it can definitely be classed as a cost-effective option when deciding to render your home. Though some of the disadvantages of sand cement render can become apparent when it comes to flexibility as acrylic render can withstand wall movement to a larger degree than cement render. Though overall traditional sand cement render is a great product that has stood the test of time, it hides imperfections of old and/or bad brickwork and creates an extra layer of protection to fight erosion.
Cement render is used for more reasons than one. Homeowners can use render to increase the life span of their retaining walls while also making them look great. Cement render thickness can vary and it will depend on factors such as the brickwork and how much render is needed to be applied so that the wall will be straight and smooth.
Cement render is usually painted and sealed. Cement Render can be painted after 28 days.
