Cracked Render Repair
Spray cork is flexible enough to bridge hairline cracks up to 2 mm — repair, waterproof and refinish your render in one job.

The problem
Why this matters
Cracked render lets water in, ruins insulation and looks tired. Replacing render means scaffolding, mess, weeks of disruption and £8,000–£20,000.
Our solution
How we fix it
Where the existing render is sound, we patch the cracks, prime, and spray a flexible 3–6 mm cork coat over the top. The coating moves with the substrate, so cracks don't telegraph through.
What you get
- Bridges cracks up to 2 mm
- Waterproofs the entire wall surface
- Avoids the cost and mess of re-rendering
- 25-year warranty on the finish
- Choose any of 28 standard colours

Inspect
Tap-test the render, identify hollow or failed sections.
- Step 02

Two cross-coats of cork for a uniform finish.
Common questions
People often ask
- What if the render is blown / hollow?
- We patch hollow areas with sand-and-cement during prep. If 30%+ of the render has failed, we'd recommend partial replacement first.
- How big a crack can it bridge?
- Up to 2 mm reliably. Structural cracks need investigation first.
