You can see the sample patch we did last year ( lower middle on chimney breast ) This won us the job – render cleaning in Leeds. We left it over winter to see how it performed compared to the rest of the untreated wall. As you can see – we are about long term results.
So the homeowner arranged for us to treat the whole house to kill, remove and deter regrowth of the algae.
First, we wash down the walls with pressured water flow, especially under sills and lintels, in the window reveals, etc . Corners can be a breeding ground for spiders and the like. Once clean, the treatment begins. We make sure the plants are moved, covered, watered down. We check the surroundings for any potential problems if overspray occurs.
Then we apply the product, at the correct strength and flow the algae will die off very quickly. With today’s selected method we got an ‘instant ‘ clean.
After the chemical has worked it’s important to wash down the walls thoroughly, to remove the dead growth leftover. Then to finish the job off we wash the windows, leaving them to smear free.
The customer had gone out before we started- when she returned we had transformed the overall appearance of her property. She was delighted with the results.
If you are debating whether to clean your house or to paint your house. Firstly, research – what is the finish on the walls? Is it a through colour render? They should not be painted, just treated and cleaned. Check with a professional
Maybe it’s a sand and cement or plaster render that is suitable for painting. Clean it – because it’s the ideal preparation for the decorator. You should never paint over biological growth.
Get it cleaned then see how it looks. You may be surprised to find it doesn’t need painting after all! If you need a render clean in Leeds -Contact us here
