Best caulk for backsplash(limestone) / countertop(granite) joint?

mratnerOctober 20, 2011

In their infinite wisdom, the contractors who were putting in the limestone tile backsplash used the same (sanded) grout for the inner corner joint with the granite countertop.

That grout is now falling out, presumably because it is not designed to bond to granite.

I read somewhere yesterday that they should have used caulk instead of grout - is that correct? In your experience, what is the best material to use for such a joint? Specific product names would be appreciated.

Thank you!

The best caulk to use is the sanded caulk that matches the grout that they used from the same manufacturer. Caulk should be applied at any change of plane, such as the corners and where the tile meets the counters. Apply a thin bead of that after you scrape all of the grout out of the joint. Never apply caulk over the grout.

Home Depot has a pretty good selection its not with caulk its with the grout, usually. Look at the big ends of the tube usually some has smeared and dried, there you can get a good idea of the final color. You should be able to get something that will go nicely. To keep it from smearing into the grout on the wall i put a strip of blue painters tape along the wall about 1/8 " away from the joint. I prefer thinner caulk lines you could go a little further away if you wanted a wider line.
