Acid Etched Limestone Tiled Bath Panel Restoration The Angel

Limestone bathroom tiles in The Angel Islington

Here we have a luxury bathroom tiled in Limestone at an apartment in The Angel in Islington. I was contacted by the letting agent who discovered the damage when the tenant moved out, although they were unsure of the cause I immediately recognised it as acid damage from the use of acidic limescale removers. These products are simply too strong for use on limestone which is acid sensitive and results in etching as shown in the photos.

The agent had new tenant’s looking to move in, but they wanted to sort the acid damage out beforehand. The etching can be difficult to remove so to make sure a good result could be achieved I did a test clean on one tile of the bath panels. The result was great, so I gave a quote which was accepted.

Given the fast nature of the London rental market there was very limited time between the old tenants moving out and the new in. However, I was able to collect the keys from the agent allowing me to squeeze the job in around my other projects.

Removing Acid Etching from Limestone Tiling

To remove the etching I had to burnish and literally resurface the limestone tiles using a set of diamond encrusted burnishing pads. Naturally I can’t use large floor pads on wall tiling however Tile Doctor also do these pads in 6-inch which fit a handheld polishing machine.

Work started with the application of a coarse 400-grit pad using water for lubrication, the soiling is then wiped away and the process repeated with an 800 and 1500 grit pads using the same process. These pads remove the etching and build up the polish on the Limestone.

Some of the staining was very deep and so to get a good result I had to use coarser 120 and 200 grit diamond blocks first. These are small hand-held blocks available in different grits that can get into awkward spaces. Once all of this was done, I rinsed the tiles down and dried them.

The last step in the burnishing process was to apply a final polish with an extra fine 3000-grit pad which adds a nice subtle polish to the stone.

Sealing Limestone Bathroom Tiling

To finish, the Limestone was sealed using Tile Doctor X-Tra Seal which is a modern oil-based impregnating sealer that enhances the colour of dark limestone and will make cleaning easier going forward.

For aftercare cleaning I recommended supplying any future tenant with Tile Doctor Aqua-Pro which is a day-to-day spray cleaner which can be used in the shower to prevent the build-up of limescale.

Victorian Tiled Hallway Restoration Muswell Hill N10

Damaged Victorian Tiled Hallway Rescued in Muswell Hill

This client bought a house in Muswell Hill N10 with a neglected Victorian tiled floor in the hallway. They planned to completely refurbish the property including adding extensions.

Prior to starting work they called me to look at the floor and see if it was salvageable. At this time, it only had the damage where a pipe had been previously laid. However, over a year later they called me back as the building project was coming to an end and unfortunately during the process of changing the layout of the downstairs the entire final meter and a half of the hallway had been damaged and broken.

Luckily, I am used to restoration projects of this nature, so I was able to provide a quote to rescue the whole floor including rebuilding the now larger section at the end of the hallway.

The quote was revised in line with the extended work that was now required to get the floor back to its original condition and submitted for approval. It was accepted and we booked it for a few months’ later to allow all other trades to finish. However, for ease of tiling and to make a neat finish I advised them not to fit the skirting board until I had completed the work. Also, I needed time to source matching replacement tiles through various specialist suppliers before the work could start.

Repairing a Damaged Victorian Tiled Hallway in Muswell Hill

Due to the scale of the tiling work, we started with the repairs rather than the cleaning. As the hallway had been widened from its original layout, we had to cut away a little more of the original pattern so we could turn a corner in the border further back and re design. This made the pattern fit more sympathetically in the new space.

Once we were finished planning everything out, we filled new concrete to the damaged subfloor paying attention to the levels so that the tiling met at even height to the new flooring in adjoining rooms.

Once the subfloor had set tiling could start which involved cutting and shaping a lot of replacement tiles to match the original pattern and dry fitting them into place. Once I was happy with the pattern the tiles were stuck into place and grouted. It was meticulous work, and the repair took a week to complete.

Deep Cleaning a Victorian Tiled Hallway in Muswell Hill

The floor was left to set over the weekend before returning to do a deep clean with Tile Doctor Remove and Go scrubbed into the tiles with a black pad fitted to a rotary machine. The floor was then rinsed with water and the slurry extracted with a wet vacuum. This product as its name suggests is a coatings remover and tile cleaner that does a good job of removing old sealers and dirt.

Next the floor was given an acid wash using Tile Doctor Acid Gel which was pasted onto the tiles and then scrubbed in, this time with a coarse 200-grit diamond pad. The diamond pad does a nice job of cleaning up the old tiles and the Acid Gel helps to counter any salts that may be lying dormant in the floor; salts are a common problem with floors of this age that don’t have a damp-proof membrane.

After this the floor was rinsed and wet vacuumed to remove as much moisture as possible. Once done the floor was left to dry overnight with assistance from several fans.

The following day work began with vacuuming dust and generally checking the tiles had dried sufficiently overnight. We know from experience it’s not a good idea to apply sealer to a damp floor as it can result in a patchy appearance.

The checks were fine and so the floor was sealed with two coats of Tile Doctor X-Tra Seal which is a fully breathable oil-based impregnator that’s ideal for old floors like this one. Impregnators work by soaking into tile, occupying the pores and thereby preventing dirt from residing there. This keeps dirt on the surface where it can be easily cleaned away.

Once done the work completely transformed the hallway and really give the house back its wow factor. Only thing left to do was to fit the skirting boards.

For aftercare I recommended Tile Doctor Neutral Tile Cleaner which un-like many of the stronger products you find in supermarkets won’t impact the sealer and reduce its life.

Victorian Tiled Hallway Restoration Belsize Park

Communal Victorian Tiled Hallway Restored in Belsize Park NW3

Details below of the recent restoration of a small Victorian Tiled Hallway at a property in Belsize Park NW3. The hallway provided access to several flats and had previously been covered in carpet. The carpet has been secured to the tiles with gripper rod that had been glued to the tiles and there was a section of broken tiles in front of the staircase that had been removed leaving an obvious hole in the floor.

I carried out a survey of the floor to determine the main issues and took numerous photographs and measurements so I could locate suitable replacements. I knew that locating replacements wouldn’t be difficult as there are a few companies that specialise in this sort of thing and I know several members of the Tile Doctor network who have built up quite a collection. Once I was armed with all the costs, I email over a quote to the managing agent which was accepted and a date scheduled for the work to start.

Repair and Cleaning of a Victorian Tiled Hallway Floor in Belsize Park

Work started by carefully removing the gripper rod and cleaning up the areas where I would need to fit replacement tiles. Tiles were then cut to fit the existing pattern and colours and dry fitted into place making small adjustments along the way until I was satisfied that I had replicated the pattern exactly. Only then were the replacements fixed into place with fresh adhesive. This type of tile restoration work is quite meticulous and the whole of the first day was spent with repairs alone.

I returned on day two to deep clean the whole floor using a strong dilution of Tile Doctor Remove and Go. This product is designed for removing old sealers but is also good at softening adhesives and other contaminates so they can be scrubbed off. I follow the recommended process of spraying the solution onto the surface and then letting it sit for ten minutes so it has time to breakdown the contaminates before being worked in with a 200-grit diamond pad. Once done it was rinsed off with water and the resultant soiling extracted with a wet vacuum.

The next step was to neutralise the floor and counter any efflorescent salts that may have built up in the tiles whilst it was covered in carpet. Old floors like these don’t have the benefit of a damp proof membrane and shouldn’t be covered as it can prevent moisture from rising through the tile and evaporating at the surface. With the carpet gone the floor can breathe again and this can lead to trapped efflorescence salts appearing. We guard against this by giving the floor an acid wash using Tile Doctor Acid Gel and then rinsing off with water and extracting as before.

I left the floor to dry out overnight and returned on day three to apply the sealer which will protect it from dirt becoming ingrained in the tile and improve the appearance.

I used Tile Doctor X-Tra seal for this which is an oil-based sealer that’s full breathable and will allow for moisture to rise through the tiles un-impeded. The oil in the sealer has the added advantage of restoring the colours in the tiles and certainly in this case put the life back in the floor.

Once done the original floor which must have been at least 100-years old was completely transformed and the tiled floor added a bit of class to the entrance to the property.
