Our client had previously employed another company to tackle this large Slate floor in Walton on Thames but they hadn’t managed to remove the old sealer due to it being an old varnish seal. Varnish was used as a traditional way of sealing stone but can be damaged by scratching and it does little to improve the look of the stone. Varnish is also very difficult to break down which is a problem as it’s important to remove the old sealant before applying new, applying a new sealer onto Varnish simply wouldn’t work.
I visited the property to survey the floor and work out which combination of products and methods would work best and after some testing and I was able to confirm that not only could the old varnish be removed but once re-sealed with a modern sealer the slate would be transformed.
The client was over the moon to hear this news as they had thought there was nothing, they could do to improve the floor.
Removing Varnish and Deep Cleaning Slate Floor Tiles
With a price and schedule agreed I returned to the property at a later date and started by tackling the varnish. The method I used was to apply Tile Doctor Remove and Go, let it soak into the floor for ten minutes and then work it in with a heavy rotary scrubbing machine fitted with a black pad. The soil was then rinsed with water and extracted off the floor with a wet vacuum.
The floor was then inspected, and each tile checked to ensure the varnish was completely gone, any stubborn areas were then spot treated and scrubbed by hand. Once I was satisfied, I set about giving the stone a deep clean by repeating the same process with Tile Doctor Pro-Clean. As before all the soil and cleaning products were then low pressure rinsed off the stone and vacuumed away. The floor was then left to dry overnight.
Sealing a Slate Tiled Kitchen Floor
I returned the following day to apply a new modern sealer. First, I tested the floor was dry using the moisture meter. It was in the acceptable readings range, so I was able to start applying the sealer straight away.
For this floor I chose to apply Tile Doctor Seal and Go, it works really well on Slate tiles and as you can see from the photographs it completely transformed the appearance of the stone. Seal and Go is a water-based blend of acrylic polymers that provides both a stain resistant surface seal and a durable low-sheen finish, being water based it has the added advantage of not giving off any odour as it dries. The client had specified earlier that they didn’t want the floor to look shiny to the resultant silky appearance was the perfect solution. Thee coats were applied, and my client was very pleased with the finish.
