How to Grout Tiles – Step-by-Step Guide and Video

Once you’ve fixed the bathroom tiles to the wall, they will need grouting to finish them off, which is an easy DIY job, even for a beginner. In this handy step-by-step guide and video we show you how to grout tiles.

For this task you will require a tub of grout/adhesive, plastic spreader or a squeegee, sponge, bucket, cloth, pliers and a scraper.

Step 1 – Remove the plastic spacers

Once the tile adhesive is dry, wipe off any excess adhesive and leave to completely set. You can then remove the plastic tile spacers with the pliers. The scraper can be used to remove any tile adhesive that’s set flush or proud of the surface of the tiles.

Step 2 – Spread the grout

Take a lump of grout, roughly the same size as a golf ball, and spread it over the tile surface with either a grout spreader or a squeegee. Use the tool at a 45 degree angle, and work diagonally across the tiles forcing the mix into the gaps.

Step 3 – Work the grout into the tile gaps

Cover approximately one square metre and work the grout into the tiles gaps. Make sure to check the drying time on the packaging. With a damp sponge wipe off the excess grout ensuring to rinse it often in clean water. At right angles, pull the sponge lightly across each tile joint.

Step 4 – Clean up excess grout

Continue grouting the tiled area and wipe off the excess as you go. If you don’t wipe off the excess grout straight away, the grouting will be really difficult to remove from the tile surface when it’s dried. Once the surface has dried you can polish with a dry cloth.

If the new tiling meets a worktop, window ledge, bath or basin, you will need to run a bead of waterproof sealant around the base of the tiles or into the gaps.

Grouting tips…

New grouting provides an affordable way to transform old tiling and freshen up your bathroom. Powered grout removers, available at hire shops, make removing old, dirt-stained grout easier. To reduce the chances of black mould growing, ensure the new grout contains a fungicide.

Grout is a fine compound that’s either sold as a powder or ready-mixed, but whichever you choose make sure it’s waterproof for long lasting durability.

Avoid adding more water to the grout to make it spread more easily, as this will only weaken the grouting.

To make a neater job of wider grout lines use a piece of dowel, (a solid cylindrical rod usually made from wood, plastic or metal) and drag it along the grout before it sets.

If you have opted for a powder mix, make up enough grout to cover an entire wall, and don’t mix old and new grout.

Some natural stone tiles will need sealing before they are laid, otherwise the grout and adhesive will be absorbed into the porous surfaces, which makes it almost impossible to remove.
