Acid Wash

Large Slate Patio Renovated in Wantage

These photos of a Slate Patio were taken in 2019 at a property in Wantage. It’s an excellent example of the transformation that can be achieved with stone patios and given the current situation something we would like to do more of.

Although structurally sound the stone looked bleached by the weather and the owner of the property wanted the patio to look like it did when it had been first laid with the colour and character of the Slate restored.

I called in to do site visit to take a closer look. The patio was situated in a sunny spot, so had indeed been bleached by the weather. I discussed what we could do to restore the tiles and they were very happy to go ahead with my quote. We booked to return the following week weather permitting.

Incidentally Wantage is an historic market town that was part of Berkshire, but it has been administered as part of the Vale of White Horse district of Oxfordshire since 1974. The town is situated around 8 miles from Abingdon, with Reading, Newbury and Oxford nearby.

Deep Cleaning a Slate Patio in Wantage

It was a large patio, so I did the work in sections starting with the application of a strong dilution of Tile Doctor Pro-Clean which was left to soak in for ten minutes. This is a concentrated, multi-purpose high-alkaline cleaner, stripper and degreaser that can be diluted at varying strengths, its effective on mildew and algae in areas that have been neglected or subjected to heavy use. Tile Doctor have numerous products that could have been used to renovate stone patio including a dedicated Patio Cleaner which is something I considered using if I needed extra cleaning power.

After ten minutes the solution was scrubbed into the patio with a rotary floor scrubber fitted with a black scrubbing pad. This action lifted the dirt and previous coatings out of the stone turning the cleaning solution into a dark slurry. The slurry was rinsed off and extracted with a wet vacuum.

I then gave the patio an Acid Wash using Tile Doctor Grout Clean-Up to further clean up the stone and disperse any residues, after another rinse with water the patio was dried with a wet vacuum. This product is a cleaner designed to penetrate below the surface to remove light grout smears (grout haze), mineral deposits, rust stains and efflorescence. We also use this product for the removal of most hard water stains, lime deposits and soap scum, it is very effective especially when used in conjunction with Tile Doctor Pro-Clean. Our client had not realised quite how dirty the patio had been!

To apply the sealer, I had to wait for a weather window when it would be dry for a few days. I know from experience that applying a sealer to damp stone results can lead to an inconsistent result that customers are rarely happy with.

After returning, I started the sealing process with the application of a pre-sealer called Tile Doctor Stone Oil which soaks into the stone and adds the deep colour the slate really needed. Once this was dry, I applied a single coat of Tile Doctor Ultra Seal to lock in the Stone Oil and add protection.

The Slate patio was completely transformed and needless to say, the owner of the property was very pleased with the result. They were looking forward to using the space and entertaining friends and family.

Quarry Tiled Hallway Floor Renovated in Didcot

This quarry tiled hallway at a house in Didcot had not been renovated for many years and any sealer that was once present on the tiles had long since worn off leaving it vulnerable to dirt which then became ingrained in the tile.

I went over to the property in Didcot to survey the floor and could see that although the floor was in good physical condition it was now long overdue a deep clean. The floor had a lovely black and white border around the terracotta coloured tiles and I was confident that this floor would look really good once fully cleaned and resealed.

Deep Cleaning a Quarry Tiled Hallway Floor

The first process was to scrub the floor with Tile Doctor Pro-Clean using a rotary machine fitted with a silicon carbide brush. This is a multi-purpose cleaner which is high-alkaline, it acts as a stripper and degreaser too so is perfect for this situation. The highly concentrated solution is left to dwell on the floor for a short time which helps it to work on the stubborn dirt. Once the floor had been scrubbed the residue was rinsed off with clean water. Finally removing the slurry produced with a wet vacuum.

To counter the strong alkaline products used on the floor and further clean the tile the floor was given an Acid Wash using Tile Doctor Grout Clean-Up. It was scrubbed into the tile and grout using a soft brush and then rinsed off with water. I then scrubbed the floor with Tile Doctor Neutral Tile Cleaner to neutralise and remove the acidic cleaner again using a wet vac to remove all the liquids from the floor. Once, I was satisfied that the floor was as clean as possible I left the floor to dry overnight.

Sealing a Quarry Tiled Hallway Floor

On day two I returned to seal the floor. The first job of the day was to test it with a damp meter first to make sure it was dry. We don’t recommend applying a sealer if the floor isn’t dry as we know from experience that the results can be patchy. Happy that we were good to go ahead I sealed the floor with several coats of Tile Doctor Seal & Go. This is a specially formulated water-based blend of acrylic polymers that provides both a stain resistant seal and a gives the floor a durable attractive low-sheen finish.

The customer was very happy with the results and left the following feedback:

“Barry was brilliant! Has made a lovely job of our hall. We had one small problem (our fault) which he rectified promptly. Would happily recommend him.”

Before leaving I discussed with the client the best way to maintain the floor going forward. Many homeowners don’t realise this but many of the tile cleaning products sold in supermarkets are designed for cleaning Ceramic or Vinyl tiles and are not recommended for use on a sealed surface as they will prematurely erode the sealer away over time. We recommended using the Tile Doctor concentrated Neutral Tile and Stone cleaner. It has been especially formulated for the regular cleaning of sealed tile and stone surfaces.
