Things to consider with grouting bathroom tiles

Grouting tiles is essentially the same job whether floor or wall tiles, you simply need to remove old grout, then get new grout into the joints to fill them completely. Grouting technique does not really matter as long as the joints are full and you do not damage the tiles while doing it! There are three main types of grout that are commonly sold in the UK: unsanded wall tile grout, sanded tile grout (usually used for floor tiles) and specialist epoxy grout. It is important to use the right type of tile grout as this will make the grouting last longer ad it may even be easier getting the grout into the gaps thereby reduce the work required.

Un-sanded grout doesn’t have sand added to it so can be pushed into tighter tile lines more easily, however, without the sand, it can experience more shrinkage which could mean some cracking when dry. As a rule of thumb, do not use unsanded grout in gaps greater than 3mm wide because of the potential shrinkage problem that can cause cracking. Sanded grout is used for gaps wider than 3mm, which in most cases will be large floor tiles.

Epoxy grouts are specialist grouts made from epoxy resins that can be used instead of sanded or unsanded grout as they do not suffer from shrinkage issues, are more flexible, plus are also normally waterproof so perfect for bathrooms. The other advantage of epoxy grouts is that they require relatively low levels of maintenance to keep them clean. Whichever grout you choose, you should always read the label and follow the manufacturer’s instructions carefully.

Doing it Yourself

Grouting bathroom tiles is a job that for some is easy, but others find it incredibly difficult to get right! What’s the difference? Well, a lot of it comes down to confidence and patience, but there does seem to be a knack to this job and some just don’t have it! Old grout can act as a breeding ground for mould or mildew in damp bathroom conditions and this can cause the seal between the tiles to be no longer waterproof. It is always worth getting a tiling professional in to deal with grout repairs as re-grouting is not a simple task for everyone. But if you have decent DIY skills and are keen to tackle this job on your own, then read on.

The best way to clean grout is to use either a steam cleaner or a special cleaning agent containing bleach. But if cleaning is not enough and re-grouting repairs are needed, then first clean the tiles and grout with a bleach solution and leave to dry before mixing the new grout and applying it to the tiled area. If much of the grout looks bad then you will have to remove it before re-grouting, rather than simply patching areas.

A drill can be a good tool to remove old grout as long as you are careful not to damage the actual tiles. But always wear safety goggles when using power tools to remove grout. Once you have removed most of the grout with the drill you can finish the job with a screwdriver or a Stanley knife blade then vacuum the surface to remove any dust and traces of old crumbling grout. When applying the new grout always remove any excess as you go along as this is much easier than cleaning hardened grout off the tiles later!

FAQ's

What are the reasons for removing the old grout from between the bathroom tiles?
The most common reasons for grout removal are if the grout is discoloured, cracked or crumbling.
Can you grout right after laying new tiles?
No, wait for 24 to 48 hours before grouting the tiles.
Can you go over old grout with new grout?
You can do this, but the results are usually less than satisfactory. You really should remove the old grout first for best results.
How long does it take for grout to dry?
You should allow the grout to dry overnight as a minimum, but preferably a full 24 hours. Before sealing your grout you need to wait even longer, maybe a few days to a week to ensure that all of the moisture has had time to be released.
Can you paint tile grout?
Yes, but you have to use paint specifically made for grout, which is more of an epoxy colourant than a traditional paint. Epoxy paint is available in many colours in major DIY/home improvement stores.
