You may have finally whittled down your choice of tiles and with our help, you may now know how to adhere those tiles to your surface. But what about grout? Do you choose a rapid setting or standard? Should you go with a light colour or a dark? With so many choices available, it’s understandable that there maybe still be some confusion as to the best type of grout to use for your particular project.
Some things you might want to keep in mind…
Powder based adhesives come in both grey and white, and rapid or standard setting variants. The decision to use white over grey is determined by the type and colour of tiles chosen as well as the colour of the grout. Lighter colour materials are ideally suited to white adhesives.
The choice of rapid setting adhesive over standard setting is really up to the person installing and their proficiency in execution. The only time a rapid setting should be considered as a must is when installing natural/agglomerated stone.
Things to bear in mind if the floor has an under-tile (electric) or under-floor (water) heating system…
In these instances, flexible adhesives and grout should be used. When installing natural stone, an anti-fracture membrane should be installed to comply with the code of practice for electrical systems. If the room has wetted areas, then a tanking membrane should be used to protect your backgrounds from any possible water damage. These are essential in wet rooms.
Grouts can almost follow suit, however, these days a flexible grout with anti-mould is the standard choice. Grouts can be smooth or coarse and you can determine which one to use by the type of material being fixed and size of grout joint width to be used. For example, for a soft tile material such as high gloss black ceramic, you’ll want to use a fine powder grout for a narrow joint grout (1-4mm).
For a truly impervious grouted joint, the use of an epoxy grout is recommended, giving you high stain, abrasion and chemical resistance.
