Preparing the Surface

The joints are cleaned and prepared before replacement material is applied.

Applying Suitable Grout

The appropriate grout is selected based on the location, tile type, moisture exposure, and specific requirements of the surface.

Proper preparation helps create a cleaner and more durable result.
