Renovating a Black Limestone Patio in Walgrave


The following photos show a large black limestone patio that had been installed at a house in the village of <b Walgrave by a local builder who had sealed the stone before cleaning it first. Doing so trapped the dirt and grout smears (ka grout haze) underneath the sealer which resulted in a hazy appearance that could never be cleaned off.

Spring is an ideal time to work on patios which tend to get stained most from leaves and other detritus during the windy autumn and then ravaged by the winter frosts. If you want to seal the stone though its best to wait until a spell of continuous hot weather for the best results.

Cleaning a Black Limestone Patio

To clean the stone, I would first need to remove the builder’s sealer, so I started by applying Tile Doctor Remove & Go which is a strong product designed to safely remove coatings such as sealers and paint from stone and tile. A strong dilution of Remove and Go was applied to the floor and left to soak in for about ten minutes before being worked into the Limestone using a black scrubbing pad fitted to a rotary floor scrubbing machine. The soiled cleaning solution was then rinsed off the patio with water and extracted using a wet vacuum.

With the sealer removed along with the dirt then next task was to tackle the smears of grout that had been left on the surface of the stone. To do this I applied a specially developed product called Tile Doctor Acid Gel which is left to dwell on the surface of the stone just long enough to weaken the unwanted grout which can be then scrubbed off. The solution is then rinsed off the patio and extracted as before. This process was done in sections worked across the length of the patio and then when finished it was given a through rinse.

I would need the limestone patio to be dry before sealing so I left it fully dry out over the course of a few days before coming back to finish off, fortunately the weather was good, and it wasn’t long before I returned.

My sealer of choice for Black Limestone is Tile Doctor Colour Grow, it’s an impregnating sealer the penetrates the pores of the stone protecting it from within and simultaneously enhancing the natural colours in the stone. This product is also fully breathable which makes it ideal for external use or damp areas where moisture needs to rise through the stone and evaporate. Two coats of Colour Grow were all that was required to fully seal the stone.

The work was a huge improvement to the look of the patio which is now vibrant, inviting and fully transformed by the process.

Acid damaged black limestone patio tiles in Bromsgrove


A local company in Bromsgrove were commissioned to lay a stunning and expensive Black Limestone patio for a customer who was renovating their property. Unfortunately, the company tried to clean the finished patio with brick acid, and because limestone is generally very porous and acid sensitive this discoloured the tiles to a rather unsightly, dull grey – a far cry from what their customer was expecting!

The company facing a large bill contacted Tile Doctor for expert advice to see if the beautiful tiles could be restored. If Tile Doctor couldn’t come to the rescue, then the company would have no choice other than to replace them at their own expense.

Black limestone paving has become incredibly popular over the last few years as its dark tones suit the current trend for a monochrome palette. It is also hard wearing and readily available.

Tile Doctor specialise in the restoration of all types of tile and stone and as their local agent, I was asked to go over and see what could be done. I realised that the brick acid will have damaged the surface of the stone so to restore it I first tried applying a coarse 200 grit diamond burnishing pad. The pad successfully demonstrated that the appearance could be restored and impressed with the difference the site foreman booked me in to complete the whole patio. Luckily the weather forecast was set fair for a few days, which would be needed to clean and seal the patio.

Made with industrial diamonds and available in different sizes and grits, burnishing pads are ideal for restoring the appearance of polished stone floors. The first step was to work on the tiles with a course 200 grit diamond pad fitted to a weighted rotary machine and lubricated with water. This took off a layer of the limestone, bringing back the original black appearance of the tiles.

Next the patio was worked on with 400 grit diamond pads followed by 800 grit pads – the first stage of polishing – and each application was cleaned off with water. Because the property was being renovated there was a lot of dirt on the tiles and grout from construction, so I scrubbed in medium dilution of Tile Doctor Pro-Clean using a CRB (counter rotating brush) machine. Once done I rinsed down the area with more water and left it to dry. As you can see from the pictures it was a large area, so this work took two days to complete.

Sealing Limestone Patio Tiles to Restore Colour

I returned the next day to start the sealing process beginning with the application of Tile Doctor Stone-Oil which restores the deep black colour and texture to the limestone, it’s also an impregnating sealer that adds protection and improves mechanical strength once cured.

I allowed this to dry for 24 hours and then applied a coat of Ultra-Seal, a no-sheen natural-looking sealer formulated to provide maximum stain protection.

The customer was very happy with the results. The patio tiles were fully restored to their original glory and their customer was delighted. More importantly, the company had been saved from making an insurance claim. They left the following feedback on completion:

“Great job by Kieron after the wrong cleaning solution was used on a patio we installed. Came up better than new!”

Unearthed Tiles Exchanged for Pavement Cleaning in Eastbourne


So, I had an enquiry from a very nice lady in Eastbourne who wanted to know if I could use some old tiles she had dug up from her garden. It seems her house was the last one to be built in the street many years ago and the builders threw all the tiles into her garden. Since then some were recovered to make a mosaic front pathway but there were four buckets of tiles she couldn’t use.

I’m based in Eastbourne, so it was no trouble to go around and take a look. I popped round and in my profession you never know when they might come in handy so I bought them off her for £20 which was a bargain really. Well I was very grateful to her and after seeing her front pathway and garden I offered to clean the paving and tiles up for free.

There were two sections of paving that needed cleaning including the mosaic tiles and with my van being parked right in front of the house I was able to reach them with my van mounted high-pressure cleaning system.

Cleaning Dirty Paving

The first job was to use low pressure jet wash to the paving to remove surface dirt and then apply a medium dilution of Tile Doctor Pro-Clean and let it soak into the tile for about ten minutes. The solution was then scrubbed into the tile using a stiff brush to release the ingrained dirt.

The last step was to finish the process using our high-powered state of the art truck mount extraction system. These machines are a big investment but well worth the cost in the amount of time they save. They work by applying hot water under pressure to the surface via a special spinner tool whilst simultaneously extracting the soiled water back to a collection tank on the van. You can set the pressure of the machine and in the case of paving I use a lower pressure to ensure the mortar between the paving isn’t dislodged.

The paving came out remarkably well as you can see from the photographs.

Thank you Joy for your enthusiasm in the finished product, for the opportunity to reveal your lovely pathway, for the buckets of tiles you recovered and for the copious amounts of tea you served to me.

Restoring a Riven Slate Patio Suffering from Grout Haze in Wollaston


This customer, who lives in Wollaston, a small village in Northamptonshire, called me to look at the unfortunate condition of her Riven Slate tiled patio. She had hired a builder to install it, but he had neglected to remove the grout haze which had occurred quickly enough, allowing it to set. He was subsequently unable to remove the haze because he had already sealed over it. This had left it looking very unsightly, as you can see in the photo below.

The customer initially contacted me back in December 2016. At that time, I did explain to the customer that the Winter wouldn’t be an ideal time to restore the patio, and that it would be best to carry out the work in the Spring. However, she was so unhappy with the appearance of the patio and – knowing she had guests coming over for Christmas – wanted something to be done to improve the condition of the tiles as soon as possible.

It was agreed that I would immediately carry out the removal of the old sealer and the grout haze beneath, but leave the re-sealing until the Spring of the following year when the weather was dry. The customer understood that when I returned in the Spring, the patio would require another light clean and brush to prepare it for sealing.

To put the customer’s mind at rest somewhat, I carried out a test clean on one slab of the patio using Tile Doctor impregnating, colour intensifying sealer, known as Colour Grow. This darkened the tile and provided a natural look finish, which was preferred by the customer. I also returned to the property several days later to carry out a water repellency test, but as you can see from the photo below, the rain beat me to it. Thankfully, the repellency test had positive results.

I was then able to begin the cleaning process.

Cleaning and Sealing a Riven Slate Tiled Patio

To begin, I removed the old sealer using a strong mix of Tile Doctor Remove & Go, which is a stripper and cleaner. This product was scrubbed into the tiles with a rotary brush machine. Net, I rinsed away the resulting slurry and soaked up the water with a wet vax machine.

This initial clean exposed the true extent of the grout haze – it was over all every tile! My next course of action was therefore to remove this using Tile Doctor Acid Gel, which is a gel cleaner specially formulated to neutralise grout haze. This was allowed to dwell for a short period before I brushed it in.

Following this, I gave the whole area a second brush with a small amount of water, before using a wet vax machine once again to make sure all cleaning chemicals were removed. I used the customer’s hosepipe to rinse down the entire patio as there was good drainage.

I allowed the tiles to dry out naturally, before waited for a dry day in April this year to return to the property. During this day, I sealed the entire area with Tile Doctor Colour Grow sealer to really deepen the colour in the stone and provide the whole patio long-lasting protection against the elements.
