Ruined Slate Patio Beautifully Restored in Pembury

Our client in the villager of Pembury was feeling really deflated after having a Slate Patio laid adjacent to the full length of her house, however the builder had not applied the sealer correctly creating a mess which ruined the appearance of the stone.

Unfortunately, it is not that unusual to be contacted about this sort of situation, applying a sealer is not as easy as manufactures make out. There are lots of factors to consider, choosing the right sealer, is the stone damp, how do you know if you have applied too much, and it often catches tradesmen out. I was able to reassure them that with the right combination of products and equipment the problem could be rectified.

The first job was to strip off the old sealer which was done using a product called Tile Doctor Remove and Go. The name of this product pretty much says it all and once applied to the stone it is left to soak in for ten to twenty minutes before being scrubbed in with a rotary machine fitted with an abrasive burnishing pad.

Tile Doctor Remove and Go is a multi-purpose stripper which will remove most coatings and sealers, including epoxy grout haze which is another common problem we encounter when tradesmen have not cleaned up properly after grouting. It is also good for removing heavy build ups of grease. I used several burnishing pads of different grits going from coarse to smooth on this patio, rinsing and extracting the soil after each pad.

It was a large area, so this process took up most of the day on its own, fortunately I use a van mounted high pressure cleaning and extraction system to remove the soil which is very efficient and leaves the stone bright clean and reasonably dry afterwards. This ensures the process can be carried out with minimal mess.

It was a nice warm summers day and although cloudy we didn’t get any rain overnight, so after checking the forecast I was able to return the next day and apply a fresh sealer to the Slate.

My client wanted a natural look, so I used Tile Doctor Ultra Seal. This product is a no-sheen, natural-look, impregnating sealer which is formulated to provide maximum stain protection. These impregnating sealers work by penetrating the stone, occupying its pores, and thus preventing dirt from residing there.

The client was so happy and relieved to see the results on what a very expensive patio and commented she was eager to get the first barbecue of the season underway.

We recommended that a regular with the jet wash should keep the patio in good condition and in a few years time we could return to reapply the sealer for them.

Deep Clean and Seal of a Multi-Coloured Slate Kitchen floor in Hythe

This Multi-Coloured Slate floor looks nice in the Kitchen of this property in Hythe, however due to the riven surface of the tile and the deep grout lines my customer had struggled to keep it clean. Additionally, the Slate has lost all of its lustre over the years since it had been installed and it was now due a deep clean and reseal.

The combination of durability and price makes Slate a popular choice for floor covering, it is also available in a number of colours, ranging from plain black to a more diverse array of shades. Like any natural stone floor though it need sealing to keep the dirt out of the pores of the stone however sealers wear off with use

Hythe by the way is a lovely medieval coastal market town with its own beach on the edge of Romney Marsh and close to Folkestone.

Deep Cleaning Multicoloured Slate Tiles

Before starting I removed the kickboards underneath the kitchen units and protected the exposed woodwork with a thin film. To deep clean the Slate floor and remove any remaining sealer I applied Tile Doctor Remove and Go and left it to soak in for ten minutes before scrubbing it in with a light carbide brush. As well as removing the old sealer this process releases the dirt from the pores of the stone and brings it to the surface where it can be extracted.

I have probably mentioned this before, but I’ve invested in a powerful van mounted pressure extraction system for removing the dirt, old sealer and emulsified soils released from the stone. The system works by applying water at high pressure on the floor via a spinner tool and then simultaneously extracts the waste under suction back to a grey water tank on the van. From the customers point of view, it makes light work of cleaning the floor and more importantly leaves the floor dry and leaves no mess.

Having a dry floor at this stage is important as it means I can usually seal the floor on the same day. Its not a good idea to apply a sealer to damp floor as it will affect the way it cures and lead to an undesirable finish. The way to make sure the floor its dry is to use a moisture meter and take readings in several places around the floor. You can use an air mover to improve drying times however older floors can take a very long time to dry and for those I tend to book another day to apply the sealer.

Sealing Multicoloured Slate Tiles

With the floor dry I set about applying the first of two coats of Tile Doctor X-Tra Seal which provides both a hardwearing sheen to the slate as well as enhancing its natural colourings. It has strong water repellency characteristics which makes it ideal for use in a kitchen where spillages are quite common.

This was quite a small kitchen, so the work was completed in one day. My client was amazed at the transformation and grateful for our advice on continued maintenance which for this floor I recommended the use of Tile Doctor Stone Soap for daily cleaning.
