Why soft wash, not pressure wash, on render
Render — especially K-Rend and other modern silicone renders — is not a surface that takes pressure. Hit it with a normal pressure washer and you’ll strip the texture, force water in behind the render, and end up with a worse problem six months later when the algae is back. Soft wash is the only correct method. Low pressure, biocide, dwell, rinse. The biocide does the killing, not the water.
- Plants and garden protected before we start
- Specialist soft-wash biocide application
- Low-pressure rinse from top down
- Algae killed at root — not just knocked off
- Honest assessment if anything won’t come up
- Final clear-up and rinse-down of paths
Render types we clean
K-Rend & modern silicone render
The most common new-build render in Surrey, and the one most often ruined by the wrong cleaning method. Soft wash is manufacturer-recommended. We clean to spec.
Pebbledash
The tricky one — lots of texture for algae and lichen to sit in. Biocide gets right into the dimples in a way pressure can’t. Comes up beautifully.
Painted render & sand-cement
Older Surrey homes. Same soft wash method. Won’t lift sound paint, will not strip the render itself.
Acrylic & through-coloured render
Soft wash safe. Colour comes back to original. No risk of streaking or lifting.
