How to Replace Grout In a Shower

Stains on shower tile grout can reach a point where cleaning no longer produces a bright and fresh appearance. You have an alternative to tearing out all of the tile. You can learn how to replace grout in a shower. Between removing old grout and letting new grout dry, the project takes two or three days to finish. New grout will result in a much more attractive shower, and the project is relatively affordable.

Before you get started learning how to replace grout in a shower, you need to choose a replacement grout. Grout comes in sanded and unsanded varieties. Gaps between tiles less than 1/8 inch require unsanded grout. Gaps greater than 1/8 inch need to be filled with sanded grout. You also have the option of using acrylic latex grout or epoxy grout. The acrylic product is the easiest to apply but needs a sealing product applied at the end. Epoxy grout is great for resisting future stains but more challenging to apply. However, you won’t have to add a sealant.
