Caulking over grout is only a temporary fix because caulk forms a poor bond with the more porous grout. Whether it takes a few months or a couple of years, the caulk will start to peel off the grout. Caulk over grout will peel off over time because caulk will not bond well with grout.

Should I seal or grout first?

Seal Before Grouting

What happens when you caulk over grout?

Is it better to caulk or grout around tub?

Since you are joining two different materials together, you should use caulk in the space where the floor tile and tub meet. Grout is not flexible, so it's not the best material for the job, while caulk allows for movement and also provides a better sealant.

Is caulk better than 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.

What happens if grout sealer dries on tile?

Can I use silicone to seal 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.

Should you caulk between tile and shower pan?

A shower or tub and surrounding walls need to be caulked to prevent excess moisture from creating damage. A caulked shower should be watertight, display limited mildew, mold, and prevent water damage when done correctly.

Do you caulk 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 happens if you don't caulk your tub?

If the tub/tile connection is caulked the water cannot wick out through the bottom grout joint and moisture builds up and is able to feed the mold that eventually develops. I am sure you have all seen that grey discolored staining of the caulk that you would swear is “behind” the caulk—-where it cannot be cleaned off?

What grout does not need to be sealed?

Why does the grout keep cracking?

Too much water or polymer additive in the grout mix is a common problem. Cracked grout is frequently the result of weak grout structure. The liquid in the grout mixture inevitably evaporates, as it was designed to do, but excessive evaporation can leave pinholes that will leave it vulnerable to cracking.

How many coats of grout sealer is needed?

(Generally speaking, it takes one to three coats of sealer to achieve adequate protection.) After the second coat dries, test the surface with a few drops of water. The liquid should bead up into droplets; if not, apply a third coat to ensure quality results. Finally, let your tiled space dry completely.
