Getting the Best from Slate Patio Pavers in Berkshire

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.

I first went round there to take a look at the job and work out a price; we often get asked to quote over the phone but it’s really difficult to do that without look at the job as you never know how things are going to work out unless you do a test clean. In this case I was able to demonstrate the process to the customer on one of the paving tiles which you can easily pick out in the photographs below.

Happy with the demonstration I was given the job to do the whole patio so I arranged to a date to come back and do the work.

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.

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.

My customer was very pleased with the final results and left the following feedback on the Tile Doctor feedback system.

“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”

Maitaining a slate wet room

This bathroom in Richmond, Surrey was tiled in Slate on the walls and floor to create a wet room effect. Overtime the old sealer had perished allowing soiling and shower products to stain tile and grout there was also evidence of heavy Limescale deposits.

Cleaning the Slate Tiled Floor

We decided to give the tile and grout a deep cleaning using a strong mixture of Tile Doctor Pro-Clean combined 50/50 with Nanotech Ultra Clean to make it more effective. To get the cleaning solution to stick to the wall tile and grout it was decanted into a spray bottle and sprayed on to the tile, this combines it with air making it lighter and allowing it to dwell on the vertical surface.

The solution was then worked into the Slate tile and grout by hand using a stiff scrubbing brush and then washed off using clean water, this process had to be repeated a number of times until we were happy that the tile and the grout were clean again. Pro-Clean is also an effective sealer stripper so will have removed any remaining sealer from the surface, this is important as the new sealer may not have been compatible with the old.

There were a number of areas that had stubborn Limescale deposits so we treated them with Tile Doctor Remove and Go which is a very strong product that as the name suggests will pretty much remove anything but is safe to use on Tile and Grout. Once this process was complete the whole area was given a thorough wash down with water a number of times to remove any remaining chemical and neutralise the surface ready for sealing.

We left the floor to dry off overnight and came back the next day to re-seal the tile and grout. We choose to do this with Tile Doctor Colour Grow which is an impregnating sealer that will sit in the pores of the tile and grout rather than on the surface and help protect it for longer, it’s also a great product to use on natural stone such as Slate as it really brings out the natural colours in the stone.
