Which Type of Grout Should I Use?

Being in the tile business for 30+ years, naturally, we’ve learned quite a bit about the installation process. Installing tile correctly is crucial for a number of reasons. For one, if the tiles are glued crookedly or spaced unevenly, it will not be aesthetically pleasing. We all want our floors or backsplash tiles to make the rooms look better, not worse! Also, improperly installed tile is prone to cracking and can even become a tripping hazard. It’s not just gluing the tiles perfectly, though. The grouting process is just as important! Using the wrong kind of grout (a bonding material that goes into the spaces between tiles) can be just as detrimental as gluing the tile incorrectly would be. If you choose a grout that is too coarse or not coarse enough, or if you pick the wrong kind, it’s a recipe for disaster. So, what is the easy (and best) solution to installing that new ceramic tile flooring in your Palm Bay kitchen? Call Island Tile & Marble of Melbourne, FL! Our professional team can have the installation process done quickly, efficiently, and correctly so you don’t have to worry about wonky-looking tiles or cracking grout in your Viera bathroom. But, if you do choose to install your porcelain tile floor or wall surface yourself, here is a breakdown of some of the main types of grout so you know which one to use.


Unsanded grout is used for closely grouped tiles with gaps less than 1/8 of an inch wide. Unsanded grout is much smoother than sanded grout, which allows it to fit into very small spaces. But, if unsanded grout is used in areas larger than 1/8 of an inch wide, it cracks easily since it doesn’t have as strong of a bond as sanded grout does.


Sanded grout, like the name suggests, is coarser and grittier than unsanded, and is generally used in grout seams 1/8 to  5/8 of an inch wide. It can come in a powder form that would need to be mixed with water, or it comes pre-mixed. Both sanded and unsanded grout also comes in a variety of colors, and both of these cement-based materials need to be sealed to prevent staining and water absorption.


This is different from the other two types of grout and is made from epoxy resin and hardener. It’s much stronger than traditional cement-based grouts, it’s more water-resistant, and it doesn’t stain easily. It is generally used for countertops and in showers and it hardens much faster than other types of grout. Epoxy is more difficult to work with compared to cement-based grout, though, so if you’re planning to use epoxy do your research or hire a professional tile installer at Island Tile.
