This customer from Farnham called me with three requests. First, can you clean and seal our Black Limestone patio? Secondly can you remove some scratches? and finally, can you make it less slippery as my children have slipped a couple of times in the wet.
After discussing the problems over the phone, we agreed a convenient date and I went along to the property to have a look. I could certainly do the first and second but not the third. There are products on the market but most Anti-slip products I’ve come across contain acids which etch and roughen the surface. Her patio was made of dark limestone which is acid sensitive and applying an acidic product would ruin the look of the stone leaving it looking washed out. I discussed with her the options and the process and we agreed a price, booking the work in for later in the month.
Cleaning a Black Limestone Tiled Patio Floor
First, I cleaned the grout lines with Tile Doctor Pro Clean which was left to soak in for about ten minutes before being scrubbed with a nylon brush and being careful not to further scratch the stone.
The next step was to clean the stone with a series of burnishing pads starting with a coarse 400-grit lubricated with water then moving onto increasingly finer pads of 800 and 1500 grit. It’s important to rinse and extract the slurry after applying each pad. This process removes the existing sealer and slightly mills the tiles firstly opening the pores then slowly closing them as the process continues. I avoided the dark area in the picture where the table was situated as it had been protected from the weather, sun and small children. My aim was to get the same consistent colour across the whole patio.
Once I had used the three pads, I completed a final rinse and extraction with a wet vacuum. I then checked surveyed the floor looking for any areas that needed more work and to verify that the scratched had been removed as part of the process. The work went well, and I was happy to see that the scratches had been lifted and the appearance of the stone looked much better and more even.
Sealing a Black Limestone Tiled Patio Floor
It was a warm day, so it wasn’t long before the stone had dried and were dry enough to be sealed. I talked through the customers options for sealing and recommended the application of Tile Doctor Colour Grow as it contains a colour enhancer which would return the dark colour to the stone and match the original colour under the table. Colour Grow is also rated for external use.
Two coats of Colour Grow were applied, and this made a big improvement to the appearance of the stone resulting in a stunning transformation. The customer was over the moon and with the patio now ready for the summer she could not wait to get the patio furniture in place and enjoy the space.
