Sealing Bathroom Tiles to Prevent Staining and Mould

Having mould in your bathroom is never a desirable situation, especially in a family home with young children. Additionally, severe mould can cause a range of health issues, including respiratory problems, nasal congestion, and throat irritation, so it’s important to remove it as soon as possible.

I mention this as I was recently called out to a family home in Bedford recently because the parents were getting worried about the mould developing in the Ceramic tiled bathroom, especially on the lower tiles and silicon around the bath. Naturally, they wanted it to be removed as they didn’t want to expose their children to it, so a quote was issued and the work to restore the tiles was booked in for the following week.

Cleaning and Sealing a Mouldy Ceramic Tiled Bathroom

Before starting the work, I covered the bathtub with dust sheets and towels to prevent any chemical spillages. Then, to begin, I applied Tile Doctor Mould Away which is specially formulated to removing mould and black spots from grout and silicone. This is quite a potent product, so it is advisable to wear protective gloves and goggles.
I sprayed the Mould Away on the entire area around the bath and shower unit, as well as the pedestal wash hand basin, before scrubbing it in by hand using a stiff brush. I left this to dwell while I started to cut out the old silicon from around the bath, and once this had been done, I rinsed the product off the tiles.

Next, I diluted a solution of Tile Doctor Grout Clean Up with water, this product contains concentrated phosphoric acid and is designed to remove grout haze, mineral deposits, and other smears. This solution was sprayed onto the worst-affected areas of the grout to remove any remaining soil deposits. I also gave the tiles a second rinse and, while the grout was drying, I finished cutting out and removing the old silicon.

Following this, I lightly dried all areas with a heat gun and sealed the grout with Tile Doctor Ultra-Seal, which is a natural-look, penetrating sealer deigned to provide maximum stain protection. Finally, I installed a fresh mould-resistant silicone sealant between the tile and bath to replace the old, mouldy silicone.

Within a short day of work, I had managed to completely transform the appearance of this Ceramic tiled bathroom. The customer was extremely pleased with the result.

Mould problems are extremely common in small bathrooms with inadequate ventilation. Whilst the regular application of Tile Doctor Mould Away will keep the problem in check you can also improve the ventilation by leaving the bathroom door and a window open for a while after use.

Refreshing the Appearance of Grout in Bedfordshire

The grout lines on this Porcelain floor in a Luton Kitchen was excessively stained and even with the application of the heavy duty cleaning products we have at our disposal it was very unlikely that it could be restored to its former standard. The best option therefore was to colour the grout using a Tile Doctor Grout Colouring kit.

Choosing a Grout Colour

The customer wasn’t completely sure which colour would suit best so I was able to test the effect of various colours within the Tile Doctor range by applying a small amount to the grout colourant in different colours to the floor and then wiping it off before it had chance to harden. This helped and the sandstone colourant was decided upon, the range includes a number of popular colours so it can be a tricky decision; I’ve included a table of the range below so you can see for yourself.

Light Grey Limestone Natural Grey Sandstone White
(Colors are displayed as accurately as possible. Some colors below may not represent exact grout colors. They may appear differently on computer monitors with different resolutions).

Colouring Grout

Before applying the colourant the grout needs to be clean and free of any debris; you can a strong dilution of Tile Doctor Pro-Clean for this Tile Doctor however do sell a special Pre-Treater product that is recommended for this, its mildly acidic which etches the grout to provide a better bond. The Pre-Treater is safe to use on Porcelain tiles but for natural stone such as Marble or Travertine I would go with Pro-Clean.

Once the floor was dry I started with the application of the white colourant using a tooth brush to paint it onto the grout, pressing down firmly to make sure it is keyed into the original grout. Once the whole floor had been covered and all the grout lines coloured, we let it dry for several hours returning to clean up the tiles. Once all the excess colourant had been removed we used a polishing pad to buff the floor back to a polishes state.

Apologies for the photographs which are not my best but I think you can see the improvement.

Dealing with Mould and Mildew on Grout

The before and after photograph below is from a job we did in a Shower Cubicle tiled with small square Mosaic tiles at a house in Bedford. As you can see from the photograph the grout had become stained with mould and mildew growth which had become quite bad and moved onto the surface of the tile.

Cleaning Mosaic Tiles

To resolve the problem a strong dilution of Tile Doctor Pro-Clean was scrubbed into the tile and grout by hand using a stiff brush. It’s best to let the Pro-Clean soak into the tile and grout for ten minutes before working in and to help the solution stick on vertical surfaces it’s best to decant the Pro-Clean into a spray bottle and spray it onto the surface of the tile, this allows it to mix with air making it lighter and enabling it to stick to the surface instead of running off.

The mould and mildew had become quite ingrained and had managed to get quite a foothold in the grout which due to its cementitious nature is actually porous near the surface. As a result the tiles were proving very had to get clean and so working in sections the process was repeated numerous times requiring a lot of physical effort and Pro-Clean before we were happy with the results.

Dirty Grout Problems Resolved

This Ceramic tiled family bathroom with shower was installed at house in Leighton Buzzard and was in need of rejuvenation. You can see from the photograph below that the tiles were in reasonable condition but the grout had become ingrained with dirt which is not unknown as the top layer of grout is porous and will discolour over time if not protected.

Cleaning Ceramic Tile and Grout

The Ceramic tiles and grout were treated using a strong 2:1 dilution of Tile Doctor Pro-Clean mixed 50/50 with Nanotech Ultraclean which combines a highly powerful Tile and Grout cleaning product with tiny abrasive particles. For vertical tiled surfaces I recommend the mixture is decanted into a bottle with a trigger spray attachment which when sprayed onto the wall allows the cleaner to mix with air making it lighter and allowing it to stick better. The solution was then worked in using a stiff scrubbing brush by hand before being rinsed off with water; this process was repeated a number of times until we had managed to clean all the areas and then left to dry.

Sealing Grout

The grout was dried and the sealed with a couple of coats of Tile Doctor Grout Sealer which forms a protective barrier over the porous grout and keeps it looking good for longer. Most sealers can be used on grout (check the label to confirm) but for best results use a spray bottle as mixing the sealer with air improves its ability to stick to a vertical surface.
