What is grouting?

Tiling grout is the material that fills the spaces between the tiles on your wall or floor.

Grout comes in several different forms from cement based to epoxy. Grout is available in a vast array of colours to compliment the tiles that you have selected from your home. Whichever option you choose, follow the manufacturer's instructions on how to mix and apply the grout.

Step One: Mix the Grout

When mixing the grout, add the water first and then the powder to ensure a thorough mix with no lumps. Follow the instructions on your packet and mix to a thick paste-like consistency.

Step Two: Apply the Grout

How to apply grout to tiles using a grouter or grout float.

Push the grout into the joints and compress by wiping over at an angle across the joints. Do not apply grout to the corners where walls meet floors and where two walls meet. You will need to apply silicone here. See photos on how to grout wall tiles.

Step Three: Clean the Tiles

How long after tiling can you grout?

Always allow the grout to dry and for a film to set on the face of the tiles. Dry times vary dependant on weather conditions. Then remove the excess grout.

Clean up with a slightly damp sponge. Don’t wash the floor or get it overly wet. The trick here is to lift the film off the tiles without wetting the actual grouted joint.

Keep rinsing your sponge as you go and change your water regularly.

Step Four: Time to dry buff!

After most of the grout has been removed from the tiles, give them another once-over with the damp sponge. Only when the grout is completely dry buff over the tiles with clean, dry cloth or sponge. If there is still dried grout present, a cement residue remover may be needed.

Once the grout is completely dry after 48 hours, we recommend applying a grout sealer.

How To Grout & Silicone

Grout – those thin lines you see between each tile on your walls or floor is a vital part of any well-done tiling job.

While tiles themselves are impervious to water, moisture would still be able to make its way under or behind them unless the gaps between tiles are sealed with the right grout. Grouting your tiles also helps to strengthen the whole installation.

Luckily, grouting is one of the simplest parts of DIY tiling. There’s no secret to learning how to grout: you just need to be prepared to work a little hard.
