Details below of a job I completed earlier in the summer in the Berkshire town of Thatcham which is just east of Newbury. The customer had a lovely Slate Patio installed the year before which had not been sealed by the builder and it had since become dull, light grey and unpleasing to the eye. Additionally there was a haze on tiles from sand and cement that had been used to point between the paving which the customer couldn’t remove.
Cleaning Slate Patio Paving
On my return the first job was to tackle the sand and cement haze that was covering much of the slate patio. Fortunately for me the builder had not sealed the tiles so this was just a straightforward case of applying a solution of Tile Doctor Grout Clean-Up, leaving it to dwell for ten minutes and then scrubbing it into the paving with a mechanical scrubbing machine to release the sandy haze as well as breaking down the soils on the tiles.
You should be aware that Grout Clean-Up is an acid based product and Slate like most natural stone is acid sensitive so it’s important to remove it as soon as its done its job and rinse down the stone with water soon after.
To rinse the slate patio I used our specialist truck mounted systems which gently blasts the soils from the stone with hot pressurised water whilst simultaneously recapturing the waste back into a tank on the van. This action also neutralises the stones which is important before applying sealer. The Slate pavers were then allowed to dry and being a very hot day this only took a couple of hours.
Sealing a Slate Patio
After a long lunch I returned to find the Slate was dry but still looking rather grey so to restore the natural dark colours to the stone I applied a coating of Tile Doctor Stone Oil then after approximately 1 hour any excess stone oil was buffed off the tiles leaving it to fully dry off overnight.
The following day I returned to apply two liberal coats of Tile Doctor Ultra Seal which is a solvent based no-sheen, natural-look penetrating sealer that will provide the needed protection from the elements and make it easier to clean in future.
“I had my patio and path cleaned and sealed. The service from the whole team has been exemplary from start to finish and I am delighted with the work that has been carried out. My particular thanks to Dennis who was friendly, helpful and exceptionally professional. He explained everything he was going to do and why, kept me informed throughout and worked really hard to produce a fantastic finish on my patio and path. I’m really grateful and will most definitely be recommending to friends. Thank you”
