Mosaic glass tiles should be grouted with care using exactly the right equipment otherwise you can end up with a DIY disaster on your hands. A lot of beginners make the mistake of spending days on such jobs only to find that the tiles do not stick to the floor properly when it comes to grouting them. Some grout is of such low quality that it does not do a satisfactory job as well, crumbling when the surface is walked on. Sealant is very important because it helps to protect the surface and keep it all together. It also stops any dirt or moisture getting in between the tiles and eventually causing damage to the surface.

Step 1: Preparations to Make

To do a proper job of grouting the tiles, you will need to make sure that the tiles are installed correctly in the first place. You should always test the adhesive first and make sure that you purchase quality supplies from reputable manufacturers. The last thing you want is to find out that the tiles simply start falling away when you disturb them to place the grouting. The grouting should also be applied only to clean and dry surfaces. Be sure that everything is clean and prepared for grouting before starting. If not, you will likely make yourself an enormous amount of extra work.

Step 2: Applying the Sealant

First, make sure that you have the appropriate sealant for the job. It should clearly state on the packaging exactly what it is supposed to be used for. The sealant will likely come with a sealant gun which you can use to make it easier to apply the sealant between the cracks without getting it into places where it shouldn’t be.

To begin with, apply the grout using a scraper at a 45-degree angle to spread it out once you have used the sealant gun to put it in place. The distribution of the grouting needs to be evenly distributed across the gaps between the mosaic glass tiles. When you have done this, leave it to dry for 15 to 20 minutes.

Step 3: Removing Excess Grout

When the grout has been left for some time to set, you should then remove any excess which has been left behind. To do this, use a dry rag or paper towel to carefully wipe the surfaces of the tiles where there is excess sealant. This must be done fairly quickly because once the grout has completely set; it will not be possible to remove it without risking damage to the tiles.

Do not use the surface for at least two days as this time will be needed for the grout to cure. If the flooring is not avoidable and must be walked on, a plywood panel should be placed on top of it as a walkway. Even this should be used with care and minimal use at that.
