How to Renovate Old Flagstone Flooring

I was contacted by the owner of this property in Leeds about renovating their old Flagstone floor. The couple who owned the house both worked long hours so after discussing the floor at length over the phone and after reviewing several photographs they emailed me to ask me to go ahead and start work. I normally prefer to do a site visit beforehand so I can provide an accurate quote, clearly however this wasn’t going to possible in this case.

The owner had arranged for his father in law to let me into the property so I could start work. I was aware from the phone calls we had that there was an issue with the pointing, and I was prepared for this, but it was worse than I had anticipated with most of the grout missing or loose. Interestingly the stone was quite yellow and so probably came from the Salts Mill area near Leeds. Sir Titus Salt was a 19th century industrialist and philanthropist built a large textile mill out of the stone. The mill is now a centre for art, dining and shopping and well worth a visit if your passing.

Cleaning and restoring a Flagstone Tiled Kitchen Floor

I decided to deal with the floor cleaning first and began by scrubbing the flagstones with a strong dilution of Tile Doctor Pro Clean using a rotary floor machine fitted with a scrubbing pad. The soil was then extracted using a wet vacuum and flagstones re-inspected. The remaining stubborn stains were spot treated using a repeat of the previous process until I was happy they were as clean as they could be. As the floor dried I took out all the loose pointing and re grouted the whole floor with a mid grey grout which matched the old flagstones quite well. The floor was now looking vastly improved. The floor was then left to dry fully overnight to ensure the seal could be applied.

Sealing a Flagstone Tiled Kitchen Floor

I returned the following morning and tested the floor with the moisture meter, I was satisfied the floor was within the accepted parameters and we could now apply the sealant. I selected to use a couple of coats of Tile Doctor Colour Grow, allowing each coat to dry before applying the next one. This product enhances the colour but leaves a matt finish. It will form a durable protective seal to the floor which will ensure the floor is easier to maintain.

I heard from the later that they were over the moon with the result and as part of the conversation we discussed the best way to maintain the floor going forward. Basically, this involves being careful with what you use to clean it as strong products can weaker the sealer. I recommend they use Tile Doctor Neutral Tile Cleaner which is pH neural and designed for the regular cleaning of sealed tiles.
