Should there be a gap between tile and wall?

Use caulk to fill a gap between tile and wall. In fact, where a tile floor meets a wall, there should be a 1/8 inch (6 mm) gap between the tile and the wall. This helps account for heat expansion and your house settling. If your tile is flush against the wall, a settling house can crack tiles or grout.

What should I put between drywall and tile?

The best product to use under tile in wet areas is cement board. This is similar to drywall in that it comes in sheets, but cement board will not develop mold or deteriorate when exposed to water.

Do you caulk where tile meets wall?

Caulk performs well in angled seams.

Grout is generally the best choice for filling joints between tiles in showers or elsewhere. but where two tiled shower walls meet, or where a shower wall meets the floor (called “change of plane”), waterproof silicone caulk (view example on Amazon) comes in mighty handy.

Can I use sanded caulk instead of grout?

Yes, there is a caulk that looks like grout. They are referred to as “sanded caulk.” They are, however, not supposed to replace the grout. You can only use sanded caulk in areas where grout may crack because it is not flexible but also if you need something that looks like grout.

Can you use caulk instead of grout between tiles?

Should you use grout or caulk in the corners?

It’s essential to use caulk, not grout, in shower corners. Grout does not hold up well in corners and is prone to cracking and falling out. This is because the tiles on the two perpendicular walls expand and contract with temperature changes.

What happens if you put grout on top of grout?

Benefits of Putting New Grout Over Old Grout

Putting new grout over old grout is not as complicated as a complete re-grout as it does not require the removal of the old grout. It can also strengthen the surface to increase water resistance and make it less susceptible to impurities.

Can I use silicone instead of grout?

Grout is a hardwearing emulsion but should only be used between joints of the same plane. This means any corners or bends that your tiles and fittings encounter should be handled with silicone instead. This is because grout is not flexible enough to withstand any structural movement. It is also not entirely waterproof.
