Every marble texture failure we are shown traces back to the surface, not the material. The finish itself is stone; what fails is the layer it was asked to sit on. Preparing the wall properly costs a fraction of redoing the job, so this is the part to be slow about.
What a wall must be before texture goes on
- Cured. Fresh plaster holds water and alkali. Texture laid on uncured plaster can discolour or debond. Give new plaster its full curing time before decorating.
- Dry. Not surface-dry after a wet week — dry through. Moisture behind a fresh finish is the single most common cause of early failure.
- Sound. Tap the wall. Hollow-sounding patches are plaster that has separated from the masonry, and they come off and get redone now, not after the texture hides them.
- Clean. No dust, no oil, no curing compound, no chalking old paint. The binder grips what it touches.
- Even enough. Texture forgives small undulations — that is one of its virtues — but it does not straighten a genuinely uneven wall.
The sequence that works
1. Inspect and repair
Rake out and fill cracks, cut away hollow plaster and re-do it, and deal with any damp source before anything decorative happens. Damp is a plumbing or waterproofing problem wearing a paint disguise — if you can see patches, salts or peeling, start with a proper diagnosis, not a finish.
2. Clean down
Wire-brush loose material, wash off dust, and let the wall dry. On previously painted walls, remove anything flaking; sound old paint can stay but must be scuffed so the primer keys in.
3. Prime
Primer evens out suction and gives the binder chemical a consistent surface to grip. Skipping primer to save a coat is how you get patchy adhesion that shows up a season later.
4. Only then, texture
With the wall cured, dry, sound, clean and primed, the dana can go on — the application itself is covered in our step-by-step guide.
Signs to stop and ask
- White salt bloom (efflorescence) — moisture is moving through the wall
- Damp patches that return after drying
- Paint that peels in sheets — the layer below is failing
- Cracks wider than a hairline, or ones that keep growing
Any of these means the wall is telling you about a problem underneath. Photograph it and send it to us before spending on material.
Frequently asked questions
Can texture hide cracks?
It hides hairlines visually, but a moving crack reopens through any finish. Fill and stabilise first.
Does an old distempered wall need stripping?
Distemper is weakly bound and comes off with washing — it must be removed, because nothing durable can anchor to it.
How long after plastering can I apply texture?
After the plaster's full cure. It varies with weather and plaster type, so follow the plaster's curing guidance rather than a fixed number of days from us.
