his is one of the most common questions we get at ACR Plastering Ltd. The short answer is — yes, in many cases you can, but it depends on the condition of the existing surface.

If the current render is solid, not blown, and properly bonded to the wall, a new thin coat silicone render system can often be applied over the top. This saves time, labour, and reduces waste removal costs

When Is It Suitable to Render Over Existing Render?

Rendering over existing surfaces is possible when:

• The render is not hollow or blown
• There are no major cracks or structural movement
• The wall is dry and stable
• The surface can be properly prepared and primed

At ACR Plastering, we always carry out a full inspection before recommending this approach.

When Should Old Render Be Removed?

In some cases, removing the old render is the better option:

• Large areas of blown render
• Damp issues behind the surface
• Structural cracks
• Poor previous workmanship

Trying to render over a bad surface will only lead to failure later.
