Removing Grout Smears from Textured Porcelain Kitchen Tiles in Newcastle

This request came from a client who lives in the Newcastle district of Jesmond who was unhappy with the appearance of their Textured Porcelain floor tiles. The problem was that the Porcelain Tiles were grouted in whilst the underfloor heating was switched on. This resulted in the grout drying out quicker than expected and the tiler struggled to get the excess grout off the tiles. To rectify the problem, the tiler tried to get the dried grout off with acid, but it didn’t work, and the floor was left looking dark and dull. Unable to rectify the problem the client was left with a disappointing pale floor and had searched around the internet for a solution.

Normally grout smears like these (aka Grout Haze) can be removed with an acidic product and Tile Doctor sell Grout Clean-up specially for this purpose. However, some grouts contain acid resistant polymers which need to broken down first. Fortunately, we have a solution for everything tile related and the system we use does not affect the main grout lines only the excess grout. I called in to do a site visit and having surveyed the problem I was confident it could resolved, I gave them a price for the work and agreed a date to return to do the job.

Cleaning a Textured Porcelain Tiled Kitchen Floor

My first task was to spray the tiles with Tile Doctor Remove and Go, this was left to soak into the tile for around ten minutes before being scrubbed in. Remove and Go is a coatings remover that is safe to use on tile and grout; normally we use it to remove old sealers but in this case I applied it to break down the polymers. To work the product into the tile I use a buffing machine fitted with a black scrubbing pad, the mechanical advantage this gives makes the job a lot quicker. Then the slurry generated is rinsed off with water and removed with a wet vacuum. The floor was then left to dry for 30 minutes.

We were then able to remove the excess grout which was done by applying Tile Doctor Grout Clean-Up which I mentioned earlier. The process was the same, i.e. using the buffing machine and a wet vacuum to scrub the floor and extract the soil. The floor was rinsed with water to remove any trace of the products used and dried as much as possible using the wet vacuum. The underfloor heating really helped at this point to dry out the floor.

Sealing a Textured Porcelain Tiled Kitchen Floor

Once the floor was fully dry including the grout lines a single thin coat of Tile Doctor Colour Grow sealer was applied. The tiles were textured porcelain, so the dirt gets trapped into the textured surface if it is not sealed. We usually find one coat of Tile Doctor Colour Grow is more than enough for this, anything that hadn’t soaked in after three to five minutes was then polished off with clean dry cloths.

The client was very happy with the floor and pleased that the excess grout had been cleaned up and the floor looked as it should. Before leaving I recommended the use a pH Neutral tile cleaner for general cleaning such as Tile Doctor Neutral Tile Cleaner. There is no point sealing the tiles only to have it stripped off later with the use of a bleach based cleaner.

Renovating Grubby Shower Grout with a Grout Colourant in Manchester

We were contacted by the client in Chorlton suburb of Manchester to look at restoring the appearance of a Ceramic tiled shower cubicle. The grout was very dirty and severely discoloured, despite trying multiple products nothing the client did could resolve the problem. Having given up on their own efforts they were considering having the shower re-grouted as a final option and contacted Tile Doctor.

I went over to the property to look at the shower cubicle and could see that although the Ceramic tiles were holding some dirt it was the grout that was the main issue. The cementitious and rough nature of the grout was holding onto the dirt and was developing mould in some places. What was once a nice crisp white shower grout had turned black and was now very uninviting.

Although we have had a lot of success using grout cleaning products such as Tile Doctor Oxy-Gel and Duo Clean, I knew from experience that it would be very difficult to remove the deep staining completely. When the grout is this badly discoloured the best solution is to clean the grout as much as possible and then use a Tile Doctor Grout Colourant to restore the colour. I discussed with them the process and they were happy with my price and gave me the go ahead.

Cleaning and Restoring a Ceramic Tiled Shower Cubicle

I set about cleaning the grout using the Tile Doctor Grout Colourant Pre-Treatment spray which not only cleans the grout lines it is also slightly acidic, so it etches the surface of the grout enabling a superior bond with the colourant which is applied later. This was sprayed onto the tile and scrubbed by hand with a stiff brush. I also used a steam cleaner with a special grout nozzle to focus the steam and draw out as much of the ingrained dirt as possible.

Once I was happy with the grout, I turned my attention to the ceramic shower tiles which were scrubbed with Tile Doctor Oxy-Gel. I then rinsed the tiles and grout with water to remove the soil that had been released. Ceramic tiles are glazed so they don’t attract dirt as easily as grout which was the main problem with this shower. The shower tiles and grout were then wiped with a cloth and gentry dried with a heat gun.

Once the grout was dry, I applied Tile Doctor Grout Colourant in white, this is simply brushed on with a small brush and any excess that gets onto the adjacent tile is wiped off before it dries, one bottle was enough to complete the job. The Grout Colourant comes in ten different colours and there is also a pack available which includes everything you need. Whilst the grout colourant was drying, I removed the old silicone sealer between the tile and shower tray and replaced with new.

The transformation was instantaneous and resulted in the shower looking like new, my client was really happy with the improvement.

It’s worth noting that the Tile Doctor Grout Colourant adds a protective barrier over the grout giving it some protection which unlike the grout itself makes it very easy to keep clean. For aftercare I left the client with a bottle of Tile Doctor Aqua Pro which is formulated for the regular cleaning of shower cubicles and will help them to keep the tiles and grout clean.
