Wall after damp proof plastering

Not sure which one you've got?

Rising, penetrating and condensation look similar and need completely different fixes. Jack will tell you which it is, free.

Elevation finished in flexible wall coating

Cracked render, stained walls

A flexible coating bridges hairline cracks and sheds water while letting the wall breathe. Ten to fifteen year finishes.

A flexible, breathable finish over the whole elevation. It bridges hairline cracks, sheds rainwater, lets the wall breathe — and makes a tired house look after itself again.

Why coat a wall at all

Two jobs at once: weatherproof and presentable.

Render cracks. It's what render does — buildings move, temperatures swing, and hairline cracking appears across an elevation over a couple of decades. Each crack is a route for rainwater to get behind the render, where it can't easily evaporate back out.

A flexible coating is applied over the existing render and moves with the building rather than cracking alongside it. It bridges those hairline cracks, sheds water off the surface, and — critically — stays vapour-permeable so moisture already in the wall can still escape.

That last point matters. Sealing a wall completely with the wrong product traps moisture inside it and makes damp worse rather than better.

When a wall is ready for it

  • Hairline cracking across the render
  • Green or black algae staining down the elevation
  • Paint flaking or blistering off the outside wall
  • Damp patches inside that worsen after rain
  • Render that has been patched in several colours
  • A house that simply looks tired from the road

Blown or hollow render has to come off and be made good first — coating over loose render just fails with it.

Our work

Full elevations, not patches

A side wall with widespread cracking, repaired and coated. We coat whole elevations so you don't end up looking at a visible repair for the next fifteen years.

How we do it

Preparation is most of the job.

The coating itself goes on quickly. What determines whether it lasts fifteen years or two is everything that happens before it.

So we don't coat over anything loose, damp or moving.

  1. 01

    Survey the elevations

    Which walls, what condition, what access. Anything above single storey needs scaffold, and that's in the quote rather than added later.

  2. 02

    Repair and make good

    Cracks cut out and filled, blown render removed and re-rendered, and any gutter or flashing issue sorted first.

  3. 03

    Clean down

    Algae, dirt and loose material washed off so the coating bonds to sound material.

  4. 04

    Mask and protect

    Windows, doors, paths and planting sheeted before anything is applied.

  5. 05

    Apply and inspect

    Coats applied to the specified thickness across the full elevation, then walked round with you before the scaffold comes down.

Send us a photo of the elevation.

A wide shot plus a close-up of the worst area is usually enough for us to tell you what's involved.

Exterior wall coating questions

How long does a wall coating last?
On sound, properly prepared render, well over a decade — typically in the ten to fifteen year range. The ones that fail early almost always went onto blown render or a wall that was still wet.
Will it stop my damp problem?
If the damp is penetrating damp caused by water coming through the wall, that's exactly what it's for. If it's rising damp or condensation, a coating won't touch it — which is why we survey before quoting.
Doesn't sealing the wall trap moisture?
It would with a non-breathable product, which is why we don't use one. The coatings we fit let moisture vapour out while stopping liquid water getting in.
Can you coat over cracked render?
Over hairline cracking, yes — bridging it is one of the things a flexible coating is designed to do. Over blown or hollow render, no. That comes off first.
What colours can I have?
A wide range, and we'll get you a colour reference to look at properly rather than choosing off a screen. Most people go a shade or two off brilliant white, which stays looking clean longer.
