What Is the Difference Between Sanded and Un-Sanded Grout?
Grout is not only essential for holding tiles in place. It also improves the aesthetic appearance of your tiles. However, use the wrong type of grout, and you will be replacing tiles left, right, and center in no time. Picking the suitable grout for your tiles is as essential as the type of tiles you use.
Grout is the binding agent that holds tiles together and prevents moisture from leeching beneath the tile, causing them to become dislodged. So which type of grout should you use when tiling your bathroom or kitchen?
This is depended on the type of tile as wells as the area usage. But first, lets us learn why each type of grout is best for specific applications.
Difference between sanded and unsanded grout
The main difference between the sanded and unsanded grout is pretty much in the name – sand. Sanded grout has sand in it, while unsanded grout does not contain sand. (No someone didn’t use a sander on it)
Unsanded grout contains cement, water, and color pigments; sanded grout has cement, sand, coloring, and water.
There are also sanded and unsanded epoxy grouts.
Epoxy grout is typically made from resin and hardeners. Sanded epoxy grout also contains sanded while the unsanded one does not have sand. Epoxy-based grout is generally used for applications where tiles will be exposed to harsh chemicals such as acid.
Applications for sanded grout
Sanded grout is resistant to shrinking as it tends to be thick inconsistency. It is best used for floor and wall tile joints that are thick. Ideally, anything over 1/8 of an inch should be grouted using a sanded grout. For extremely wide joints, use heavily sanded grout.
You should be able to find different sanded grout consistencies for different joint widths at any local hardware or flooring store. Lastly, you can use sanded grout in smaller joints. But you may end up with pinholes, and the grout is increasingly challenging to use on limited spacing.
Applications for unsanded grout
Unsanded grout is best used for narrow joints that are less than 1/8-inch-wide. It is mainly used for grouting ceramic wall tiles. It tends to cling well to vertical surfaces, and its smooth texture makes it ideal for use in tiles that are easily scratched, such as marble, glass, and metal tiles.
It is not advisable to use unsanded grout on foot tiles as it will crack when stepped on, causing your tiles to dislodge.
