When render needs restoring, not replacing
Most older render is still well bonded to the wall. What’s failed is the surface: the paint has chalked and faded, mould and dirt have stained it, and fine cracks have opened up. Stripping and re-rendering a wall like that is expensive and unnecessary. Restoring it gives you a finish that looks new and is better protected than it was.
Signs your render is ready for a recoat
- A chalky residue comes off on your hand when you rub the wall
- Faded, patchy or uneven colour, especially on sunny elevations
- Dark staining, mould or algae on shaded walls
- Fine cracks across the surface, or old patches that show through the paint
- Flaking or peeling paint over otherwise sound render
How we restore render
- Inspect and tap-test to confirm the render is sound and mark any drummy or cracked areas.
- Clean the walls and treat mould and algae so the new coating bonds to a clean surface.
- Repair cracks and replace loose or drummy sections. See render crack repairs for how we deal with the cause.
- Prepare and prime with the primer the coating system calls for.
- Apply a membrane texture coating, a thick, flexible coating that seals the render, bridges fine cracks and gives an even, durable colour.
Texture coating or paint?
Membrane texture coating
- Much thicker film than paint
- Flexible, so it bridges fine cracks
- Evens out old patches and texture
- Can carry a manufacturer’s system warranty
Exterior paint
- Thinner, mainly a colour layer
- Fine cracks can show through again
- Old repairs often remain visible
- Suits render that’s already in good shape
Changing colour? A restoration is a good time to update the look of your home. A recoat in a new colour can completely change a facade without touching the render underneath.
If your render is drummy across large areas or coming away from the wall, restoration won’t be enough, and re-rendering is the better option. We’ll tell you which one your walls need.
