How Grouting the Tiles?

Choose a grout. There are two main types of grout: sanded and unsanded grout. Sanded grout is used when the gaps between light color tiles are larger than 3mm. Unsanded grout is used when the gaps between wood tiles are smaller than that. Measure the gaps between your tiles to find out which grout is best for your project.

Glass tiles almost always come in sheets these days and these sheets tend to have very small gaps between the marble tiles, meaning you will probably want unsanded grout. It is important to choose the right grout for your project because not doing so will cause cracks (and all the problems that come with them) in your tiles. There is also technically epoxy grout, which you can use, but it is more expensive and difficult to apply if you do not have experience applying grout.

Mix your grout. Mix your grout according to the instructions on the packaging, making sure to also mix in any additives you want. It should have a consistency like smooth peanut butter. Make sure that you mix no more than what you can spread in 20 minutes. This will keep the grout from drying out. You should only work on small areas at a time, finishing one section before continuing on to the next, so plan on mixing many small batches of grout.

You can get grout additives that make it more mold resistant or water resistant, as well as additives that do things like giving the grout a color. Spread your grout. Grab a grout float and get ready to spread! Working in only a small area at a time (again, what you can cover in 20 minutes), spread the grout onto the wall tiles. Hold the float at a 45 degree angle and criss-cross the gaps between the tiles. You do not want to move the float parallel or perpendicular to any tiles, since this will push the grout out of the gaps.

Let the grout cure for 20 minutes. Use the float to remove the major excess grout and then let the grout begin to cure. Wait roughly 20 minutes, or whatever time is recommended in the instructions for your specific product, so that the majority of the grout can set enough for you to remove the excess that is on the tiles.
