Limestone tiled floor Damaged by Citric Acid Restored in a Wokingham

The photographs on this page show the spot restoration of an acid damaged newly installed Limestone tiled floor at a medieval cottage in the historic town on Wokingham, Berkshire. It seems the customer accidentally spilled lime cordial on honed surface leaving dull stain spots on about six to eight tiles.

After attempting to remove the damage themselves using a variation of different sealers the customer accepted defeat and contacted Tile Doctor to see if the issue could be resolved. If not, they were considering replacing the floor.

Being the local Tile Doctor for the area I was asked to take a look and advise the customer. I explained that the dull spots had appeared because the surface tension of the limestone had been damaged from the citric acidic in the cordial. The affected tiles would essentially need to be re-polished; the customer was eager to see if I could resolve the issue and get all the tiles to be as uniform as possible.

Spot Polishing a Limestone tiled floor

My first task was to identify which tiles needed re-polishing with burnishing pads as once I got going it would be tricky to spot them; I did this by simply leaving post it notes on the affected areas.

To restore the appearance of the Limestone tiles I started with a 400 grit 3-inch pad fitted to a handheld flex machine. You can’t actually buy these 3 inch pads, they are found in the centre of the large 17 inch floor pads. The 400-grit pad is quite abrasive and needs to be applied with water to lubricate. I then followed the 4-stage burnishing process increasing the surface tension with each pad used this to leave the tile with a good sheen and most importantly a uniform appearance with the surrounding tiles.

The Burnishing pads are actually loaded with industrial diamonds and you apply them in sequence starting with the coarse 400 grit pad before moving onto the medium 800 grit pad, fine 1,500 grit pad and then finally the super fine 3,000 grit pad which really brings up the shine. You have to rinse with water between each pad to remove the slurry that is generated. The final 3,000 grit pad is applied with very little water and so the floor is dry when completed.

Spot Sealing a Limestone Tiled Floor

The last step was to carefully re-seal the tiles that had been burnished so they would blend in with the rest of the floor. I decided on Tile Doctor Ultra-Seal for this, it’s an impregnating sealer that doesn’t alter the colour of the stone leaving them with a natural look.

The process went well and was completed in around four hours, my customer was very happy with the result and left the following testimonial on the Tile Doctor feedback system

“We felt very comfortable with the recommended course of action and Mr Buckland inspired confidence so we were happy to let him get on with the remedy.”

Travertine Floor Re-polish in Hook

Photographs below of a Travertine tiled floor we were asked to re-polish in the kitchen of a house in the village of Hook in Hampshire. The main problem was the floor had been sealed very badly and made worse when the tiler tried to rectify the problem leaving a dull and stained floor.

Stripping and Re-Polishing Travertine

To strip the sealer from the floor and get it back to the original condition we used a set of diamond encrusted Burnishing Pads fitted to a rotary machine. You start with a Red stripper pad with water to remove the sealer, moving onto the White, Yellow and Green pads which polish the floor. Once the surface was restored we applied two coats of Tile Doctor Pro-Seal which is a premium, no-sheen, natural look, water based, penetrating sealer formulated to provide maximum stain protection to the Travertine and the Grout.

The customer was over the moon at the finish and I’m sure the tiler breathed a big sigh of relief as well.
