grout flakes out of tile/granit joint

sheilajoyce_gwSeptember 4, 2008

We have black granite counter tops in the kitchen and white tile backsplash. The contractor put white grout under the first run of the tile where it meets the granite counter. I am assuming he did not put anything under or behind the granite counter against the wall and under the tile to hold the grout. Anyhow, that line of grout keeps flaking off at the lightest touch. I saw something on a tv remodel show where it looked like they mixed powdered grout with a silicone caulk for that joint. Is that the answer to my problem? If so, how do I do it and what products do I use?

No grout will stay in this joint.
It should be caulked, not grouted.

Is there a special kind of caulk for using on tile and granite?

Acrylic latex, 'Siliconized' acrylic, or silicone, just NOT butyl.

Also, grout companies offer sanded caulks that match the grout color and texture for just this purpose.

I have existing granite countertops with backsplash of the the same granite. The joint was grouted when installed and the grout continually comes out and looks bad. Can I caulk over the old grout instead of regrouting or do I have to remove all of the old grout before doing anything.

You need to remove at least enough of the old grout to get a decent bead of caulk into the joint.

Change in plane that involve different support structures should be caulked.
The supporting structures are very likely to move differently, and grout cannot absorb any relative movement without failing.
