All4Walls Cleaning render & Stone Cladding Removal

Recently self-coloured cement and silicone-acrylic renders have become very popular for both new build and refurbishment projects. Renders such as K rend, Weber, Parex have replaced the so-called “made on site” sand and cement render.

Having a factory made or proprietary render installed can have big advantages.

However, Installers and manufacturers claims that coloured render systems are maintenance free or that the  render is self-cleaning should be taken with a generous “pinch of salt” Coloured renders and wall coatings can quickly lose their kerb appeal

The picture of this K Rend (often called k render) was taken after about 5 years after being finished

 This cream self-coloured render was applied to a new build concrete (blockwork). We did not install this render, although we did provide an estimate for a 10mm base coat (2X5mm) with mesh reinforcement) and a final finish of 1.5mm textured silicone render. This would have been a much better finish as it would have kept much cleaner and had no pattern staining (blockwork outlines showing through).

The finish is  K- Rend self-coloured render, often believed to be maintenance free by many architects.Close proximity to trees has made this new coloured render shabby in no time. You will also note the shape and pattern of the blockwork showing through this is due to the render being applied too thinly. These pigmented or self-coloured renders can minimise the need to paint for many years but mother nature can quickly discolour and break down these renders. What was once an attractive weatherproof façade can quickly be turned into a shabby looking building. Even renders incorporating so-called self-cleaning Nanotechnology can quickly become soiled with dirt and organic growth. Often architectural details such as cornices,  window sills, defective copings stones and rainwater goods can cast water down the façade. This can exacerbate the effects of discolouration. Self-coloured renders and wall coatings can quickly succumb to discolouration if trees are close by. Render and wall coatings or paints can also get dirty by the effects of pollution, acid rain and bird droppings etc.
