We often get asked to do a combination of jobs at Tile Doctor so we have to be prepared for the unexpected, like getting asked to clean an old Sandstone fireplace whilst your cleaning a Victorian tiled floor at a house in Preston. We normally charge extra for these types of jobs but it depends how much cleaning is required.
This Fireplace had been in use for a number of years and due to its grainy texture was hard to keep clean, dirt and soot had built up on its surface and there was no sealer visible, either that or it had worn off with the heat.
Cleaning and Sealing a Sandstone Fireplace
To clean the uprights and Hearth I applied Tile Doctor Oxy-Gel which being in Gel form and not a liquid, stays in place increasing dwell times and doesn’t drip where it shouldn’t. In this case I let it soak into the stone for about forty minutes before scrubbing it in with a stiff hand brush and steam. Some marks were still visible after this process so we opted for using handheld Diamond blocks in 50.100.200 and then 400 grit to grind off the staining and restore the surface finish. Using these small handheld blocks takes off some of the heavier texture as well as cleaning the stone at the same time, but is really useful to use where chemicals alone struggle to get the results required. Once fully clean the fireplace was rinsed with water a couple of times and the slurry removed using a wet vacuum. After speed drying the stone with a heat gun it was ready for a couple of coats of Tile Doctor Colour Grow, even we were impressed with the results.
Cleaning and Sealing a Victorian Tiled Floor
The Red and Black Victorian Tiles were cleaned with a strong dilution of Tile Doctor Pro-Clean which is very similar to Oxy-Gel only in a liquid form. The product was left to soak into the tiles for about ten minutes before being scrubbed in with a black buffing pad attached to a slow speed buffing machine. I used the wet vacuum again to soak up the residue and stubborn stains were retreated until I was satisfied.
Old Victorian floors rarely have a damp proof membrane installed and so it’s not uncommon for damp to rise-up through the ground and tile resulting in white salt deposits being left on the surface. To prevent this process, which is commonly referred to as Efflorescence, Tile Doctor Acid Gel was applied. The solution is scrubbed into the tiles and then rinsed off with clean water and removed with a wet vacuum ready for sealing.
Victorian Tiles can take a while to dry and in this case I left it two days before returning to apply a breathable sealer to protect the tiles from ingrained dirt and staining. In this case a couple of coats of Tile Doctor Colour Grow were applied. If you recall this was the same sealer we used on the fireplace as the customer wished to bring out the colour and have a Matt finish.
