Dealing with Mould on Grout

A common problem with bathroom and shower cubicle tiles is the appearance of mould on the tile, grout and silicone which if not tackled on a regular basis will spread and threaten to severely damage the appearance of the tiles, along with the silicone. This problem is usually due to inadequate ventilation however the good news is that with early intervention with Tile Doctor Mould Away spray the problem can be reversed.

The two photos below show a bad case of this very problem at a property in Northampton, where you can see that the grout and silicone sealant had become black with mould.

Cleaning and Repairing Damaged Shower Cubicle Grout

Firstly, I decided to cut out the damaged grout with a hand held disc cutter and remove all the silicone at the base of the shower. To treat the less invasive mould in the rest of the cubicle I sprayed it with Tile Doctor Mould Away, which is specifically designed to remove mould from silicone and grout.

I sprayed the product onto the affected areas and left it to dwell for five minutes, before scrubbing it in with a stiff grout brush, resulting in a good clean. The area was then rinsed with plain water. Finally, I replaced the grout and the silicone that I had removed earlier with a flexible grout and a white silicone, both of which include a mould inhibitor.

The photographs above show the end result. The customer was very happy with her refreshed tiles, and left the following feedback:

“Phil was brilliant – both when he came to look at the job and then when he returned to actually make the grout repairs. Most importantly he explained what was (and wasn’t possible) and did exactly what he said he would do. My shower area now looks brilliant and I’m no longer showering in fear of the tiles falling off the wall! Honest, clean, timely and totally professional. A tremendous job well done. Thank you.”

I left the customer with a bottle of Tile Doctor Aqua Pro to aid with regular cleaning. If used once or twice a week, this product will help maintain the condition of the grout. I also advised the customer that it is good practice to rinse the tiles down with plain water using the shower head after each shower to remove any soapy residue which can slowly discolour and stain grout over time.

Dealing With Blackened Grout on Travertine Kitchen Tiles

Earlier this month I was in the town of Northampton, to see a client who had reported a problem with her Travertine kitchen tiles. Basically the grout between the tiles was badly stained, to the point of appearing almost black.

The Travertine tiles were also in need of some maintenance, and so I was commissioned to provide a clean, polish and a fresh seal. Travertine is a popular choice for kitchen flooring due to its relatively high durability and distinct features. My task was to get this floor back to looking its best.

Cleaning badly stained grout

My priority was to address the badly stained grout so I cleaned the grout lines by hand using a combination of hand brushes and Tile Doctor Grout Clean-Up. The surface was pre-wet with water, before a solution of Grout-Clean Up and clean water was applied to the surface. The brushes were then used to agitate the solution. Grout Clean-Up contains a mix of concentrated phosphoric acid and cleaner designed to penetrate below the surface of the grout to remove grout stains, smears and mineral deposits.

As you can see from the photos, Grout Clean-Up made an immediate difference to the appearance of the tiles. This product is suitable for use on masonry and acid resistant surfaces. After completing the clean, I gave the floor a thorough rinse to neutralise the floor after cleaning and removed as much of the water as possible using a wet vacuum.

Burnishing Travertine tiles

Following this, I paid attention to the tiles themselves, cleaning them to achieve a polished effect by using a system of burnishing pads. Tile Doctor burnishing pads comprise a set of four pads varying in grit type, from Coarse and Medium to Fine and Very Fine. I applied all four pads in turn to the floor, stopping to rinse the floor in between each. The result was a high quality polished finish.

I then left the floor to dry completely overnight, before commencing the seal the next day. My choice of sealing product was Tile Doctor Colour Grow which is a colour intensifying sealer that both enhances the natural appearance of the stone and provides a durable surface seal.

My client was very pleased with the finished product, and left the following comment on the Tile Doctor feedback system: “efficiently done”, yielding “good results”.
