The blocks on the Spring Head Parkway site had been finished using a modern silicon-based render. While this type of render is good for weather-proofing and protecting buildings, it is prone to particularly stubborn staining. This is because discolouration works its way into the pores of the render, staining the surface deep inside and making it difficult to clean.
Because the staining was within the pores of the render, deep cleaning was required. As both jet washing and power washing could potentially damage the surface of the silicon-based render – and as soft washing would not have been effective – we used our patented super-heated steam treatment. This targeted treatment removes heavy stains like rust, without damaging the surface of the render.
Our patented P.A.S.T. cleaning process has 4 stages:
P. – Preparing the render and the area
A. – Applying the biocide to the render
S. – Steam cleaning the render at 150 degrees Celsius
T. – Targeting treatment at any stains remaining on the surface.
When these four stages are used together, they’re incredibly effective at removing stains and cleaning modern render.
In order to ensure the treatments are applied correctly, our operatives receive COSH training. This covers the application of biocide — the chemical that kills algae and prevents regrowth. One of the most important stages of the process, the biocide helps to leave the property looking its very best.
In order to get the best results from façade cleaning and restoration, we 3D print our tools and equipment for each job we do. This helps us to give each property a deep, thorough clean and get the render looking as good as new.
On the Spring Head Parkway site, we were able to use our patented equipment to clean 95% of the blocks. Using these techniques allows us to operate from the safety of the ground, using rope access wherever necessary. As this approach means we don’t need scaffolding, it saves the client a huge amount on access costs.
