X-Tra Seal

The photos below are of a Black Slate floor that was installed in the Conservatory and Kitchen of a property in Clifton Bristol. Overall, the floor was not in a bad condition, however the grout had become loose, and was missing in areas. It had been several years since the floor had been sealed, and therefore our customer felt it would be best to tackle the grout, clean the floor and reseal it all together.

I attended the property to conduct a survey and chose a small inconspicuous area to perform a test clean. I like to do a test clean as it determines which products have the most impact and shows the customer the result that can be achieved. I took measurements and worked out a detailed breakdown of the costs including grout replacement and grout colouring where required. This was gladly accepted, and we scheduled the dates.

Deep Cleaning a Natural Black Slate Tiled Conservatory Floor

Upon my arrival, all the furniture had been removed and the floor was clear so I was able to make a start on the loose grouting. This must be done carefully to avoid damaging the Slate tiles. With the grouting removed and cleared away I prepared the new grout which and applied it to the areas where it was required.

Once the grout has set attention moved to cleaning the floor with a strong solution of Tile Doctor Pro-Clean. This was applied to the surface and left to soak in so it could get to work breaking down the dirt and old sealer. After about ten minutes the solution was scrubbed into the floor using a black pad fitted to a rotary buffer. The grout was then scrubbed using more Pro-Clean and a grout brush, then once done the soiling was extracted using a wet vac.

The customer wanted some shine to her floor, so I had suggested honing the stone with burnishing pads to add a deep polish. To do this three burnishing pads were run over the floor starting with a coarse 400-grit, then 800-grit and finishing with a 1500-grit. The pads are applied using the buffing machine using only water for lubrication. After each pad the floor is rinsed and the soiling extracted with the wet vacuum as before.

Once done the floor was inspected and after reviewing the grout lines it was decided that grout colouring would be needed to achieve a consistent appearance.

The floor was allowed to dry off overnight and word resumed the next day starting with sealing the Slate. To achieve the best result for the Slate two Tile Doctor sealers namely X-Tra Seal and Colour Grow were mixed together and applied to the floor. This combination wors well on Black Slate and really enhances the deep dark colouring in the stone. Two coats were applied left to soak into the stone and then the excess polished off by hand.

Once the sealer had dried, I set about applying the Grout Colourant using a Tile Doctor colourant in light grey. The colourant is basically painted onto the grout with a small brush and any excess wiped off the tile. This grout colourant gives the grout a uniform appearance and adds an impenetrable barrier over the grout sealing it in and keeping it safe from further staining.

The customer was delighted with the results and said we had transformed their kitchen.

For aftercare cleaning I recommend the use of Tile Doctor Neutral Tile Cleaner which is a gentle but effective cleaner that won’t harm the sealer. Many of the floor cleaning products you find in supermarkets etc are not for use on sealed stone, they contain strong chemicals such as bleach etc which will strip off the sealer prematurely so best avoided.
