I was asked to take a look at restoring a Victorian Tiled Floor in the Cumbrian town of Barrow in Furness where the floor had been covered in black bitumen; the bitumen was so thick it was difficult to gauge the condition of the floor underneath. I did a test clean which came out well but I had to explain there could be tile damage and other hidden problems so very difficult to quote for however we agreed a date and price and I came back a couple of weeks later to do the job.
Removing Bitumen form Victorian Tiles
Removing the bitumen from the floor without damaging the tiles underneath was a slow process involving spraying on a strong solution of Tile Doctor Remove and Go, letting it soak in, applying steam and then carefully scraping off the bitumen. The floor was treated in this manner a small area at a time and a wet vacuum was used to rinse and remove the resulting slurry. This process took up the whole day and was completely successful at removing the bitumen, before finishing I gave the floor a thorough rinse with clean water and used the wet vacuum to dry the floor was much as possible before leaving.
Sealing a Victorian Tiled Floor
I had used a lot of water cleaning the floor so I agreed with the owner to leave the floor for a few days before sealing it so it could thoroughly dry out. When I did return I used Tile Doctor Colour Grow to seal the tiles, the customer had wanted a satin finish but having weighed up the options including the fact that there was a damp problem in the house I felt Colour Grow which is a penetrating and breathable sealer would have the best longevity.
The customers were very happy with the results and before leaving we discussed aftercare cleaning, with sealed surfaces you have to be careful not to use acidic products as this can reduce the life of the sealer.
