Replace grubby grout in the shower

2016-03-03 06:00

NO matter how hard you scrub, bathroom and kitchen grout often becomes discoloured and unsightly. This is usually caused by unsealed cementitious grout which is porous and easily stained.

Regular cleaning with a soapy substance can leave a sticky film that attracts dirt which, over time, will be absorbed into the grout, causing discolouration.

Apart from the discolouration, moisture and humidity in bathrooms and kitchens creates an environment conducive to mould and mildew. It is difficult to remove these stains, as they are rooted deep in the grout. Often the best solution is to regrout and seal the area.

TAL shares a useful step-by-step guide to removing and replacing grout in a shower.

You will need

TAL 2kg wall and floor grout in the colour of choice

Rubber gloves

Goggles and dusk mask (if mould is present)

Knee pads (when working on floor tiles)

Grout rake

Small chisel and hammer

Mixing bucket and mechanical mixer

Sponge with rounded edges

Grout squeegee

Cloths for cleaning

Grout sealer

Good to know

You may also want to have a vacuum cleaner on hand to clean up the mess.

It may not be possible to find an exact match to your existing grout and if this is the case, it is advisable to re-grout the entire area. It is also important to allow sufficient time to complete this project. Over and above the preparation time, allow for at least 24 to 48 hours for the products to cure sufficiently.

Here’s how

• Remove the grout with a grout rake, which is available at your local Builders or tiling retailer. Rub the toothed edge of the blade back and forth in the middle of the grout joint until it is worn all the way to the substrate.

Using a small chisel and hammer, clean up the edges of the tiles by chipping out any remaining grout.

Take extra care not to damage or chip the edges of the adjacent tiles.

• Use a vacuum cleaner to remove any dust left in the grout joints before moving on to the next step.

• Follow the instructions on the grout packaging for the correct mix ratio. It is important to use the correct amount of liquid in the grout mix. Too much water in the mix causes colour variations and also affects the integrity of the grout, resulting in a soft and powdery product. Add the grout to the stipulated amount of clean, cool water while mixing.
