Putting New Life Into Industrial Yorkstone Flagstones

For this job, I had the pleasure of visiting the historic Salts Mill, a former textile mill turned art gallery, shopping centre, and restaurant complex near Bingley, West Yorkshire. It was built in 1853 by the famous manufacturer and philanthropist, Sir Titus Salt, and was at one point the largest industrial building in the world by total floor area.

As you can imagine, a lot of the rooms at Salts Mill are over a century and a half old. Most of them also contained stone flooring made from Yorkstone - a type of Sandstone unique to Yorkshire, and easily distinguishable due to its rich, natural yellow colouring. Unfortunately, one such floor in the Salts Mill was in quite a bad state. It has completely lost its vibrance - appearing more grey than yellow - and was evidentially in need of a very deep clean and fresh seal.

Cleaning an Old Yorkstone Floor

I started the Yorkstone tile restoration by soaking the floor in a strong dilution of our reliable alkaline-based tile cleaner, Tile Doctor Pro Clean, and scrubbing it in using a rotary machine fitted with a scrubbing pad. This quickly removed the initial layers of muck and, in the process, revealed oil-based paint and glue stains all over the floor.


To break down the oil and paint I applied Tile Doctor Remove & Go, which is our heavy duty stripper, remover and degreaser. This quickly ate through the paint and glue, and I followed by giving the floor another thorough clean with Pro Clean. Finally, I rinsed the floor with clean water before leaving it to dry for a full two days due to the amount of chemical cleaning product and water applied.

Sealing an Old Yorkstone Floor

Upon my return to the Salts Mill two days later, I ran some quick damp tests to check for any excess moisture which could've prevented me from sealing the floor. Thankfully, the floor was dry and ready to be sealed, but it is always recommended, especially with older floors, to be aware of damp issues as these can be very troublesome.


My choice of sealer was Tile Doctor Seal and Go, a topical sealer which provides a robust, stain resistant seal and a durable low sheen finish all in one product. Multiple coats of Seal and Go were applied, bringing the life and character back to these classic tiles.
