The pictures below testify to the amazing difference we were able to make to these Semi Riven Brazilian Slate tiles on the floor in the kitchen of a house in Greater Manchester where the tiles had become dull and the grout stained
Cleaning Brazilian Slate Tiles
The first step was to strip any remaining sealer from the slate and give the tiles and grout a really good clean. For this we used a strong dilution of Tile Doctor Pro-Clean which makes an effective stripper in conjunction with a buffing machine fitted with a black scrubbing pad. For best results we left the solution to dwell and gave the grout lines a good scrub with a grout brush. This does involve getting down on your knees and using a lot of elbow grease but most machines struggle to get between the tiles so it’s really the only effective way of getting the job done. We rinsed the floor down three times with clean water to remove any remaining cleaning solution and neutralise the floor ready for sealing, a wet vacuum machine comes in very handy at this point.
Sealing Brazilian Slate Tiles
We left the floor to dry overnight and came back the next day to seal. There are a number of sealers we could have chosen from for this purpose and in this case we went with Tile Doctor High Shine sealer which is recommended for Slate floors and does exactly what it says on the bottle offering stain resistance whilst leaving a deep shine. We applied four coats leaving enough time between each coat to dry; the pictures really speak for themselves and I’m happy to say the customer was very pleased with the finish.
For after care we advise the use of Tile Doctor Neutral Cleaner, some cleaners are slightly acidic and this can erode the sealer, Neutral Clean however has a neutral PH formula which won’t damage the sealer allowing the floor to keep its looks longer.
