If your rendering requirement is not listed above then please feel free to contact us to discuss your requirements. All of our rendering services are carried out to the highest industry standards using trade quality materials. By working in a professional and controlled way we aim to minimize disruption during the time work is taking place. When the external walls of a building have been constructed from concrete blocks, it is standard practice to protect the block from the weather and give them a smooth finish by applying coats of render. Traditionally renders have been made from sand, cement and waterproofer mix and finished whilst still wet. The sand and cement render has then traditionally been painted to give it a more attractive color and to further protect it from the elements.
