Sealer Removal

Cleaning and Sealing Riven Slate Floor Tiles in Horsforth

The pictures below are of a Riven Slate floor at a house in in the Leeds suburb of Horsforth which had been laid ten years prior. It’s probably difficult to appreciate from the images but the sealer on this floor was well worn through in the high traffic areas making it patchy in places. Without the protection of the sealer dirt was now ingrained in the pores of the stone leaving it looking dull. Riven slate is always tricky to clean thoroughly due to the rough surface and that combined with the ingrained dirt was making it very difficult to keep clean.

The floor now needed to be stripped of old sealer and then resealed and although I can provide a price for this over the phone my preference is to visit the property and survey the floor. In the case the owner had sent me some photographs via email however they were not too clear and so I felt it would be best if I paid the customer a visit to ensure I could give them an accurate price.

The floor was indeed overdue a clean and seal, as suspected dirt was ingrained into the areas where the seal had worn off. The house was home to a very busy family, so the area was subject to the significant traffic. I carried out a test clean on a small area and they were surprised by the results, when you live with a floor for so long you don’t notice the very slow decline in its appearance. They agreed to my quote and we arranged a time to return and carry the deep clean out.

When I arrived, I started off by protecting the skirting and surrounding woodwork. Given the rough surface of the floor I first applied Tile Doctor Wax Away which is a very effective coatings remover that is designed for removing wax but works very well in these situations. The product was left to dwell for a round ten minutes so it could get to work breaking down the old sealer and then scrubbed in using a black scrubbing pad fitted to a rotary machine.

This process removed most of the dirt and old sealer, but some stubborn patches remained. To treat these, I replaced the black pad with a coarse 200-grit burnishing pad and finally some handheld diamond burnishing blocks for the edges and corners where more intricate work was required, and the circular pads struggle to reach.

I gave the floor a rinse, and extracted the soil with a wet vacuum, the floor was then left to dry off overnight.

The next day I returned, first the slate floor was checked for moisture using the moisture meter. Once I was happy it was within the correct parameters, I then sealed with four coats of Tile Doctor Seal and Go. This is a modern water-based blend of acrylic polymers that provides both a stain resistant surface seal and a durable low-sheen finish also being water based there’s no smell as it dries.

The sealer really brought the stone to back to life and the lovely colours in the natural stones were now evident. The patchy appearance of the floor was gone, and the customer was happy.

I discussed with them how they should maintain the floor and advised them to use Tile Doctor Neutral Tile Cleaner. This is pH neutral cleaner that won’t prematurely erode the new sealer like the stronger products you find in Supermarkets which are only for use on Vinyl and Ceramic floors.

Kitchen Slate Floor with Inlaid Granite Renovated in Harrogate

I was recently asked to survey an unusual stone floor at a house in in Harrogate comprising of Slate inlaid with Granite. The client advised that it had not been cleaned properly for 20 years and wanted it renovating! It was now definitely overdue a deep clean and professional attention. Fortunately, having worked on these floors for many years I knew I could make a substantial impact and transform its appearance. Fossilized slate is a beautiful stone when cleaned and sealed correctly.

The owner confessed they had actually been sealing the floor every two years but without a deep clean first, so they were effectively sealing in the dirt each time. I discussed with them the process I would use to clean and re-seal the floor and we agreed a price to carry to out the work.

To remove the layers of old sealer and dirt used a set of Tile Doctor Diamond Burnishing pads. The pads are attached to a rotary floor machine starting with the coarse 400-grit pad which was lubricated with a dilution of Tile Doctor Remove and Go to help strip the floor of dirt and layers of sealer. After rinsing and extracting the soil I worked through the different grades of pads in sequence finishing with the 1500-grit and this time using just water for lubrication.

A set of diamond handheld burnishing blocks were then used to clean up the edges and corners where the large 17” pads struggle to reach. This ensures all areas are treated and free of dirt and old sealer.

The floor was then rinsed and extracted again to remove the remaining soil. I find a wet vacuum is an invaluable tool for this. The floor was then left to dry out overnight ready for sealing the next day.

I returned the next day to seal the floor, first checking with a damp meter that the floor was dry, and the moisture reading was below the acceptable level. These results were fine, so I had a green light to continue and seal the stone.

The customer wanted a shine on the floor so rather than apply a satin sealer which I felt wouldn’t adhere to the stone properly I decided to polish the floor further with a the last of the four burnishing pads which is a very fine 3000-grit pad. You don’t need to use a lot of water with this last pad just a small amount sprayed onto the floor using a technique we refer to as a ‘Spray Burnish’.

To seal the floor, two coats of Tile Doctor Colour Grow were applied. This is an impregnating matt sealer which intensifies the natural colours of this beautiful stone and provides long lasting durable protection.

Even I was impressed with the finished result but more importantly the client was over the moon. To keep the floor looking its best I recommended they use Tile Doctor Stone Soap which is pH neutral. You should always read the label in detail when choosing a floor cleaning product as many are too strong and not recommended for sealed stone surfaces as they will prematurely erode the sealer.
