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.

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.

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.
