What is Grouting?
Grout is a paste like material that is used to fill in the gaps between tiles once they have been affixed to the wall or floor. You can get grout ready mixed if you prefer or you can buy it in powdered form. The powder is the cheaper option but the ready mix is the easiest as no preparation is necessary. You will mostly find that grout is white but it is available in a variety of different colours if you require it.
A couple of basic things you need to remember before choosing your grout are where it will be and when the tiles were placed. If your grouting will be used in areas where they are likely to be exposed to water you should ensure you purchase a waterproof grout. Secondly, you need to ensure the tiles have had proper time to set before you begin grouting. When all tiles have been laid, wait at least 24 hours before you begin grouting. Check the instructions of your adhesive product for a more specific waiting time.
Wall and Floor Tiles
Use a Grout Spreader to apply the mixture. Drag the grout loaded spreader across the tiles and ensure that all gaps are completely filled. Do not worry about the thin layer of grout that will cover the face of your tiles.
Allow the grout to dry for approximately 15 minutes and then clean off the excess using a damp sponge. Wipe carefully and diagonally to the grout lines to avoid cleaning out the grout in the grooves between the tiles. Remember to rinse the sponge frequently with clean water.
After approximately two hours the grout will have begun to properly harden. Use a grout stick to smooth out the joints and provide the ultimate professional finish.
Once the grout has fully hardened polish the tiles with a dry cloth for a neat and clean finish.
Quarry Tiles
Grouting quarry tiles requires mortar instead of grout in most cases. This is a mixture of one part cement and three parts sand. Mix thoroughly and add a little water until the mixture is smooth.
Quarry tiles are also prone to staining because they are unglazed so it is a good idea to protect the tiles before you begin grouting. Use a tile sealer or grout release to stop the grout damaging the quarry tiles and permanently staining them.
