Cleaning before painting or re-rendering

Owner or decorator preparing a surface for coating.

Masonry paint does not fail because it was the wrong paint. It fails because it was applied over a living, damp surface, and the growth simply carried on underneath it.

Kill, then coat

A pre-decoration clean has to remove growth and treat what is left, not just rinse the wall. Anything living under a new coating will push it off within a couple of seasons.

This guide sits under our Wall Cleaning & Softwash work, covering 20-mile radius of Plymouth.

Drying time

Render holds water for longer than it looks. We build in drying time between clean and coat and will tell your decorator what we would want to see before they start.

Working with the decorator

We are happy to sequence around a decorator's dates. It usually saves them a day of preparation and gives them a sound surface to work onto.

Questions we get on this

How long between cleaning and painting?
It depends on the substrate and weather. We give a realistic window rather than a fixed number.
Do you paint as well?
No - we clean and prepare. That keeps the responsibility clear for both trades.
Will the clean damage the old coating?
Softwash will loosen already-failing paint. That is a benefit, not a fault, before recoating.
