All you need to know about re-grouting the tiles in a bathroom including costs of materials, labour and time frames.
There are a number of reasons why people decide to clean, remove and replace grouting in the bathroom. Probably the most common reason is simply that's the grout colour has faded and looks dirty so needs changing. The next most common reason is that the grout is cracked, crumbling or missing out of the joints, this can happen if the grouting was not done properly in the first place or it could simply be due to the age of the grout. If the grout is simply stained or black and mouldy, then usually it can simply be cleaned using some sort of bleach preparation to remove the mould. Removing and replacing the grout can transform your bathroom tiling and make it look brand new again, but this won't last if you have a mould problem and you do not address the root cause. If the mould is brown in colour this can often mean water is getting behind the wall tiles and soaking through the joints. In this case there is no point re-grouting until you have found and fixed the leak.
To remove the old grout a drill is perhaps the ideal tool as you can go over the surface of the grout removing as much as possible without damaging the actual tiles. When using power tools to remove grout, always wear safety goggles as flying debris could possibly injure your eyes. Once you have removed as much grout as possible with power tools you can finish the job with a screwdriver or a Stanley knife blade then going over the surface with a vacuum cleaner to remove any last traces.
There are many different types of grout for tiles, some of which are designed for floor tiles and some for walls. There are ready-mixed grout products and others you have to mix yourself, but if you are replacing your grout due to mould problems then some grout products have built-in bacterial and antifungal protection which may be useful. The ready-mix grouts on sale are far easier to use and are highly recommended.
To grout your tiles you need a special tool called a grout float, a tool to mix the grout if you do not buy the ready-mixed variety plus a scraper to get rid of any excess grout as you work. You should always clean off any excess grout as you go along as this is easier than cleaning the tiles later when the grout is dry. Once you have grouted all of the titles you can then use a damp sponge to remove any excess grout then leave the grout to dry according to the manufacturer's recommendations.
Before you start removing the grout it is always worth seeing if it is possible to perhaps salvage some of the grout by cleaning it and perhaps using a mould treatment. There are also some great tile revival systems on sale which can clean and colour your tiles, in many cases avoiding the labour intensive job of completely re-grouting the tiles. Sometimes you can simply make your own cleaning solution using bleach and baking soda to make a paste which can be applied to the old grout using a toothbrush. But please remember if you're using bleach always wear goggles and gloves with old clothes. Home-made grout cleaners will work but not in all cases, however, they are so cheap to use it is always worth giving them a try. But the fact that you're reading this article probably means you have already tried cleaning the grout and have found that replacing the grout is now your only real option.
Be careful when removing grout as it is possible you could chip or crack the bathroom tiles which will mean increased time and costs replacing broken and cracked tiles ( Assuming, of course, you can even find tiles to match!). If you do damage the tiles you need to remove the grout from around the damaged tile then use a chisel to remove the tile itself full stop then apply adhesive to the back of the new tile and position the tile using spacers to maintain proper grout gaps. When the grout is dry simply remove the spacers and grout the joints.
