What are Specialist Renders Like?
When looking at rendering your home, you will more than likely come across the term Silicone/scratch render.
While both cement-based and lime renders are traditionally mixed on site with sand, and applied in two or more coats, Silicone/Scratch come already supplied in bags/Tubs ready for mixing with water and can be applied in the traditional way with a trowel.
Implications of Damaged Render
The most common cause of cracking and bulging, however, tends to be frost action on moisture trapped between the render and the wall. This is why small hairline cracks should be sealed when they first develop, otherwise water penetrating through can freeze and expand, blowing the render surface loose — resulting in even larger cracks.
In some cases, missing lumps of render are also simply down to physical damage. Either way, once damp becomes trapped behind the surface it can penetrate through solid walls
Eroded or Damaged Brick or Stone
Signs of ageing can sometimes be a good thing, conferring what is known as ‘period charm’. On the other hand, they may be indicators of trouble ahead.
Evidence of weathering in the form of minor erosion to old brick or stone is fairly common and needn’t be a concern where it only impacts on a few localised areas. But in cases where erosion has become excessive, the damaged masonry will need to be repaired or replaced.
Signs to look out for include crumbling and spalling to the face of brick or stone, and damp penetrating the wall which can sometimes leave white salts on the surface. Walls in exposed areas like roof parapets are especially vulnerable to erosion.
