Grouting Tiles

DIY Projects - Grouting tiles

Grout is a paste that is used to fill the gaps between the tiles. Grout comes either ready mixed or in powdered form. The powdered form is cheaper but you must make sure the manufacturers instructions are followed regarding the amount of water needed for mixing it into a paste. The most common colour for grout is white but it is available in a range of colours.

When grouting around areas that are exposed to water such as a shower or around a bath, use a waterproof grout.

When all the tiles are in place including any cut tiles and the adhesive has had time to set (check the adhesive manufacturers instructions), normally at least 24 hours, you are ready to begin grouting.

Spread grout Use a grout spreader to apply grout to the joints, drag the loaded spreader across the face of the tiles and make sure all the gaps are completely filled.
Remove excess grout Allow the grout to dry for about 15 minuites before cleaning off the excess. Use a sponge dampened with clean water to clean the tile surface, wipeing diagonally to the grout lines. Rinse the sponge out frequently with clean water.
Smooth joints When the grout has begun to harden usually after approx. 2 hours, use a grout stick or similar to smooth the joints and give a neat professional finish. Allow the grout to harden fully then polish the tiles with a dry cloth to remove any remaining grout.


DIY Projects - Grouting quarry tiles

Grouting quarry tiles can differ from ceramic tiles as mortar is usually used as a grout. Make up the mortar mix using one part cement and three parts sand, once the sand and cement are mixed together add water and mix until a smooth consistency is achieved.

TipUse thinned linseed oil as a tile sealer.

Seal tiles Quarry tiles are unglazed so are prone to staining. Before grouting it is wise to protect the surface of the tile with tile sealer or a grout release, this will stop the surface of the tile being stained by the grout.

Polish and seal tiles When the grout has dried remove any traces of grout from the face of the tiles, using a damp cloth, allow the tiles to completely dry and apply a coat of tile sealer.
