Bleach-Damaged Slate Poolhouse Tiles Restored in Oundle

This very nice house in a village near Oundle in Northamptonshire features something we don’t see too often in residential property – an indoor swimming pool. The pool is surrounded by some very complementary and rustic looking Slate tiles which act as the flooring in the poolhouse.

However, over the years, the Slate tiles had been badly damaged by the chlorine bleach which is used to sterilise the pool water. The cumulative effect of people splashing water onto the tiles or walking around wet on the floor had caused the sealant to break down and the bleach had left a white blotchiness on the stone. I was asked to rectify the situation by deep cleaning the tiles, resurfacing some of the damaged stone, and applying a fresh sealant.

Cleaning Bleach-Damaged Slate Tiles

My first course of action in restoring these tiles was to clean the entire floor using Tile Doctor Pro-Clean, which is a strong alkaline-based cleaner for most types of natural stone. This product was scrubbed into the tiles using a stiff brush fitted to a rotary machine. After cleaning, I rinsed the floor with fresh water and used a wet vacuum to soak up the resulting slurry. Although the pool was protected with a cover I had to take care not to allow any of my cleaning water to contaminate the pool.

The process was effective in removing most of the white calcium deposits caused by the bleach, but not all of them. I tackled the more embedded stains with Tile Doctor Acid Gel, which is a blend of phosphoric and hydrochloric acids which treats stubborn smears such as these. The gel was brushed onto the tiles and left to dwell for 15 minutes, and then agitated using a black stripping pad fitted to a rotary machine.

After rinsing the floor again, I found that there were yet still stubborn stains remaining that didn’t respond to chemical cleaning. I decided that removing these would necessitate a more aggressive approach, and so used a set of diamond-encrusted burnishing pads to literally remove the damaged layer of stone and resurface the face of some of the badly damaged tiles.

Sealing Slate Tiles

The tiles were left to dry overnight after being cleaned and repaired. The next day, I returned to the property to applying the fresh sealant. For this I used Tile Doctor Colour Grow, a sealant which impregnates the stone to provide maximum protection and enhances its natural colours.

The customer was very impressed with the result and was very much keen to make sure the tiles remained in such good condition, so I made sure to provide the groundsman with instructions on routine maintenance.

I informed him that each time the pool is used the entire area needs to be hosed and brushed down as no sealer can withstand continuous exposure to chlorine bleach. I also left a complementary tin of Colour Grow sealant with him for periodic top-ups, as well as information on the yearly maintenance plan we offer at Tile Doctor.

Cleaning and Sealing Kitchen Slate Tiles in Towcester

These photographs of a Slate tiled floor were taken in the Kitchen of a house in Towcester where the slate was looking rather dull and had lost its appeal. This does happen with natural stone floor where the sealer which can add a shine to the stone becomes worn down and ineffective.

We removed the kickboards from the kitchen units and lined the skirting boards with green Frog tape in order to protect them from cleaning fluids. The next step was to soak the floor in a dilution of Tile Doctor Pro-Clean which we let soak into the tile for 10-15 minutes before scrubbing it in with a rotary machine fitted with a black pad and then using a stiff grout brush to clean out the grout lines.

The floor was then thoroughly rinsed using clean water which was then removed using a wet vacuum. The floor was now free of sealers etc. and this showed up a few stubborn areas that needed to be retreated and washed down again. It’s important to give the floor a good rinse to ensure it’s free of any cleaning products as they can upset the sealer.

Sealing the Slate Tiled Floor

The floor was left to dry and we came back the next day to seal the slate using five coats of Tile Doctor Seal and Go applied using a paint pad applicator. I usually use Seal and Go for slate tiles as it provides good stain protection with adds a nice sheen finish that adds to the look of the floor.

The job took two days and the floor now looks much better and much easier to clean, certainly the customer was very pleased and left the following message on our feedback system.

Phil is extremely professional and provided excellent customer service. He explained the process in detail and did a thorough job and worked extremely hard. The job was completed in the time proposed with a brilliant result. We have no hesitation in recommending Phil to others. Thank you.
