It is also not entirely waterproof.

How do I stop my shower grout from cracking?

What happens if you use tile adhesive instead of grout?

Tile adhesive is made specifically to bond tiles to the subfloor or the walls. Grout is used specifically to fill in the space between the tiles and further seal the spaces from water, bacteria, and dust. Though some of the ingredients may be shared between the two compounds, they are not interchangeable in any way.

Is there such a thing as flexible grout?

Flexible grout is urethane-based, which means it does not stain and does not ever need to be sealed. For repairs due to improper underlayment, flexible grout is less expensive than replacing the entire floor. Flexible grout is much easier to install than epoxy grout.

Where can I use caulk instead of grout?

Grout is only used to fill the joints between tiles, while caulk can seal seams in many spots—along baseboards and crown molding, on windows to stop leaks and drafts, and anywhere two construction materials meet, even on outdoor concrete. This makes caulk the more versatile of the two products.

When too much water is added, it begins to create an issue with the bonding of the substance.

Can water cause grout to crack?

Too Much Water or Polymer Additive
