Sealer Removal

Slate Floor Cleaning and Sealing Burwell

Restorative Cleaning and Sealing of a Slate Flooring in Burwell

A client from the village of Burwell near Cambridge had recently moved into a property with a Slate tiled floor and was unhappy with its condition as it never looked clean. After discussing the problem over the phone, it was clear to me that the sealed has worn off and dirt was now lodged deeply in the pores of the stone making it difficult to clean.

The tiles were installed throughout much of the ground floor so there were several areas including the kitchen and living room that needed attention. Apart from the ingrained dirt the Slate floor was in good shape and just needed a deep clean and fresh sealer applied to renovate it.

I created a quote for a restorative clean and seal which was accepted, and a date agreed for the work to begin which should take two days, one to clean and then one to seal.

Deep Cleaning the Slate Tiled Floor

The first step to restore the stone was to remove what was left of the existing sealer. This is necessary to achieve a consistent finish as the wear on a sealer is always uneven due as the busiest areas wearing down first. To do this I sprayed each area of flooring with a dilution of Tile Doctor Remove and Go which is a coatings remover that is ideal for removing sealers, it’s also a powerful cleaning agent.

The Remove and Go was left to soak into the Slate tile for ten minutes before being worked in with a rotary machine fitted with a black scrubbing pad. The grout lines were also scrubbed at this point, this needs to be done manually with a stiff grout brush as the pads struggle to reach into the recesses of the grout lines. The resultant slurry was then rinsed away and extracted with a wet vacuum.

Last step before finishing for the day was to give the floor an acid wash using Tile Doctor Grout Clean-up. This cleans up the tiles by removing old grout smears that happen during installation and further cleans the stone.

After a final rinse and extraction with the wet vacuum the floor was left overnight to dry off.

The next day I returned to apply a protective sealer checking first that the stone was dry using a moisture meter. We don’t recommend applying a sealer to a damp floor as this can lead to a patchy result.

Once satisfied the Slate was dry, multiple coats of Tile Doctor Seal and Go were applied. This is a water-based sealer (so no smell) that adds good stain protection and adds a nice subtle sheen to the tile which really enhanced the colours in the slate.

The Slate floor was completely transformed by the work and my client was so impressed with the result they asked me to return and work my magic on their Travertine tiled bathroom.

For aftercare cleaning of sealed Slate floors, I recommend the use of Tile Doctor Neutral Tile Cleaner which is a mild but effective tile cleaner. You need to be careful when choosing a cleaning product for sealed floors as many products are simply to strong and will erode the sealer prematurely.

Limestone Floor Polished in Fordham Cambridge

Honing Limestone Flooring Before House Sale in Fordham Village

A client from Fordham on the outskirts of Cambridge called us in to renovate their polished Limestone flooring that ran throughout the ground floor. Years of general wear had made the stone lose it lustre and the client wanted it looking its best as they were looking to sell the property.

Polished stone flooring does look incredible and gives any property a premium feel, however it does require regular maintenance if it’s to look its best. In fact, Tile Doctor offers a Maintenance Plan for floors like this one where we pop back once or twice a year to re-polish the stone with a high grit pad and top-up the sealer.

Without maintenance of this nature the polish will slowly wear down and eventually the sealer will fail allowing dirt to becoming ingrained in the stone and making it difficult to keep clean. The solution is to strip what’s left of the old sealer off the stone, bring up the polish using a set of diamond burnishing pads (Honing) and then re-seal and this is what I recommended for this Polished Limestone floor.

Cleaning and Honing a Polished Limestone Tiles

Before beginning the restoration, I took the usual precaution of covering the walls and kitchen units with thin blue plastic to protect them from exposure to any cleaning products or mess.

Working in the different areas one by one my first task was to give the Limestone a deep clean using a dilution of Tile Doctor Remove and Go, which is a coatings remover designed to break down any old sealant remaining on the tiles. This product is scrubbed in and then extracted, as well as removing the old sealer it also does a good job of cleaning the stone and grout. To extract the soils and clean the tiles afterwards I use a high-pressure hot water cleaning and extraction machine which is built into my van and keeps any mess to a minimum.

After completing the initial cleaning process, I moved on to honing the stone which slowly restores the polished appearance. This is done using a set of Diamond encrusted burnishing pads of different grits which slowly resurface the appearance of the Limestone tile removing scratches and other imperfections.

The process starts with the application of a coarse 400-grit pad, fitted to a rotary machine and is applied only with water to help lubricate the process. The resultant slurry is then rinsed away and the process repeated with a medium 800-grit pad again with water. At this point the polish on the stone starts to build and after another rinse and extraction is followed by a fine 1500-grit pad.

Finally, a very Fine 3000 grit pad is applied dry with only a little water sprayed onto the stone. The process of burnishing is a gradual but highly effective means of achieving this kind of finish.

After burnishing the tiles and to achieve a really hard wearing and high polish I covered the floor in Tile Doctor Shine Powder crystals and buffed them into the Limestone tiles using a White buffing pad. Then to give the floor extra protection I applied a couple of coats of Tile Doctor Ultra-Seal, which soaks into the pores of the stone to prevent dirt from becoming ingrained there.

Ultra-Seal was chosen because it’s an invisible sealer which won’t affect the appearance of the Limestone resulting in a very natural appearance. You won’t realise its there until you spill something on the floor and then you will notice it pooling on the tiles to form a bubble that can be easily wiped off.

It took some time, but once completed the Limestone looked great with a really deep high shine that the light bounced off.

Encaustic Tiled Hallway Floor Before After Restoration Waterbeach

Encaustic Tiled Hallway Cleaned and Sealed in Waterbeach

I was called out to renovate this Encaustic tiled hallway in the Cambridge suburb of Waterbeach. It’s difficult to appreciate from the photographs but the floor was showing signs that the sealant had failed, and no amount of cleaning would get it too look as clean as it used to. Sealers prevent dirt from becoming ingrained into the pores of the tile which leads to a dulling of the overall appearance. My customer was keen to have the floor renovated and asked if I could give it a deep clean and seal.

Traditional Encaustic tiles resemble ceramic tiles but are in fact made from multiple layers of compressed cement and usually feature intricate geometric shapes and patterns which are hydraulically pressed into the surface. The process first appeared in medieval times and these tiles can often be found in very old buildings.

Modern production methods have seen a resurgence and you can now find these popular patterns reproduced with ceramic tiles. Ceramic tiles don’t usually need sealing and are therefore very low maintenance. Encaustic tiles however being cement based do need sealing and when used as a floor tile you will need the sealer replacing every three to five years depending on wear. If you like the look of these tiles and live in the local area its worth giving Cambridge CTD Tiles a visit as their local showroom stock several similar styles in Ceramic.

Removing Old Sealers from Encaustic Cement Tiles

After protecting the skirting boards with tape, I set about getting the floor clean and free of what was left of the old sealer. Removing old sealers first is important as to apply new sealer on top of the old will result in different thicknesses and the floor looking patchy. To do this I applied a strong dilution of Tile Doctor Remove and Go which is a coatings remover and cleaner. It’s sprayed onto the floor, left for ten minutes and then scrubbed in with a rotary machine fitted with a black scrubbing pad. The floor was then rinsed with water and the soil extracted.

To bring up the appearance of the encaustic tiles I polished the floor with an 800-grit and then 1500-grit diamond burnishing pads using a little water to help lubricate the process. I rinsed the floor with a little more water and extracted the fine slurry generated after each pad was applied. The floor looked much better already.

Sealing Encaustic Floor Tiles

I gave the stone a few hours to dry off and due to the warm conditions, I was able to apply two coats of Tile Doctor Colour Grow impregnating sealer on the same day. Each coat was left to dry off before applying the next. Tile Doctor Colour Grow is a colour intensifying impregnating sealer that provides durable protection by occupying the pores in the tile so dirt can’t become ingrained there.

Before leaving I finished off the floor by removing any excess sealer residue with a 3000-grit polishing pad.

The client was very happy with the floor restoration once completed. I discussed with them the best aftercare and recommended they should use Tile Doctor Neutral Tile Cleaner which is pH neutral so will maintain the integrity of the newly applied seal and will ensure the floor is protected for some time to come. It is suitable for regular use, has a nice fresh fragrance and a small amount goes a long way.
