Cement Rendering Process and Finish Explained For The Rookies

Posted on

Cement rendering is a popular finishing technique applicable to most masonry. However, it is often used on bricks to enhance their aesthetic and functional appeal. The rendering material has three primary components: sand, lime, and cement. The purpose of the lime to ensure that the finish retains its structural integrity at all stages. It keeps the render from cracking, especially when it cures and hardens.

On the other hand, cement acts as a binder and finisher that determines the colour of the render. Light coloured cement will give you a light shade and so forth. If you want to learn more about cement rendering, here is a discussion that shades more light.

The Preparation Process

The preparation process is key to getting the most of your cement render finish. It starts by cleaning the concrete or brick surface to remove dust, dirt, and grease clinging on to it. You also need to get rid of any silicone sealants and friable particles. If you have smooth, dense surfaces like metal window frames and concrete, consider their low absorption rates. Such surface requires a dash coat to provide a suitable base for the cement render.

Dash coats are a mix of water and cement flicked over the surface to provide an ideal surface for the cement render.

The Benefits of Cement Rendering

Cement rendering has several benefits over other finishing techniques. It allows you to go for smooth finishes or adventurous, textured touches on your surfaces. Additionally, you can change the outlook of the surface by painting to a preferred shade. The render doesn't tie you down to one look for years to come.

The Primary Use

Cement rendering is a great way to finish concrete surfaces. However, the predominant use of the rendering process is to protect brickwork, which is susceptible to damage if left exposed. Rendering ensures that the sun doesn't hit the bricks directly. It also keeps rain from pouring over and penetrating the brickwork. Without the render, your bricks can easily develop mould when sunrays combine with the moisture from the rain.

The Finishing Options

Cement rendering allows you to finish your surface in several ways. These include:

  • Bagged or patterned finish – a bagged or patterned finish is the result of rubbing a damp hessian ball into the rendered surface to produce unique patterns. Your rubbing style will determine the pattern.
  • Trowel finish – if you want a trowel finish, use a wooden float to skim the rendered surface. The result is a smooth, dense surface.
