Replacing a Failed Sealer on a Riven Slate Tiled Flooring in Boston
The pictures below are of a Riven Slate Tiled floor in the Kitchen and adjacent Dinning area at a property in Boston. The customer was very unhappy with the state of the Slate flooring and was at the point of taking the tiles up as they couldn’t keep it clean.
I paid a visit to the property so that I could understand all the issues and work out a quote for restoring its appearance. Whilst there I was able to confirm that the existing sealer had worn away so much and was now letting dirt into the stone. The Slate also looked dull and permanently dirty.

The solution would be to remove the old sealer, deep clean the floor and then apply a fresh sealer that would give the desired finish. The new sealer will prevent dirt from becoming ingrained in the stone, keeping it on the surface where it can be easily cleaned away.
Happy with the plan and quote the work was booked in.
Removing a Failed Sealer from Multi-Coloured Riven Slate Tiling
To remove what was left of the old sealer a strong dilution of Tile Doctor Pro-Clean was applied to the tile and grout and then left to soak in for ten minutes. We find this gives the product time to break down the old sealer and soils and makes the cleaning easier.
The floor was then scrubbed with a Black scrubbing pad fitted to a rotary machine working it into every part of the floor several times. The grout was also scrubbed by hand with a stiff brush and more Pro-Clean. The floor was then rinsed with water and extracted with an industrial wet vacuum.
With the soiling removed from the floor, the Slate and Grout was inspected and then the process repeated as needed until I was satisfied all the old sealer and dirt had been removed.
Once the cleaning was done I setup a Turbo Dryer so speed up drying times and left the floor to dry off overnight.
Sealing Multicoloured Riven Slate Floor Tiles
The following day I used a damp meter to test the slate and confirm it was dry before applying the sealer. The results indicated the Turbo Dryer had done its work and the floor was ready for sealing.
The sealer chosen for this floor was Tile Doctor Seal and Go, it works well on Slate and results in a very attractive deep shine. The area was a busy kitchen dining space so I applied enough sealer to ensure it was fully sealed making use of the Turbo Dryer to speed up the drying time. The sealer didn’t let us down and added a durable finish that brightened the whole area brought out the natural tones in the slate.

My customer was delighted with the results and before leaving I took time to discuss floor maintenance. I explained that with the fresh sealer in place it should only need a quick mop to keep the tiles clean. I also explained that its important to use a PH neutral cleaner when cleaning a sealed floor as anything overly strong will strip the sealer from the floor.

The property owner couldn’t figure out the best way to improve the situation and so called me in to see what could be done. Upon inspecting the tiles first hand I decided that the best course of action would be a very deep clean and the application of a fresh sealant to offer long-term protection against ingrained dirt.
Satisfied that the floor had been cleaned as throughly as possible, I then installed several turbo dryers to thoroughly dry the flooring, allowing it to be ready for sealing the next day. Efficient drying was especially important here due to the amount of water used in the cleaning process; many tiled floor owners will already know that sealant cannot be applied if any moisture remains.
Looking at the photos of the floor before and after my work you can really get an idea of the transformation achieved in a short space of time. What a difference! The property owners were very pleased with the results, especially now that they are aware of the best way to keep their lovely Riven Slate tiles clean and protected.



My choice of sealer was
My client was delighted with the results and I think you will agree the floor looks transformed and much more appealing. Additionally the sealer is now protecting the stone from staining and liquids form puddles on the surface of the tile instead of soaking into its pores.



To extract the now soiled cleaning solution the floor was rinsed using water which was then extracted using our wet pick up system. Once the floor was clear we were able to see where more work was required and the process was repeated until we were happy the floor was thoroughly clean and free of any remaining sealer.
The customer was delighted with the results and left an excellent review which you can read below:
