Fixing Cracked Grout Lines along the Backsplash

Recently I noticed this ugly little crack along the counter top and backsplash. When we had our house built, we saved baggies of left over grout for this type of problem.

It was an easy fix. I just taped off the quartz as to not get any on the countertop, mixed the sanded grout with a little bit of water, put on a disposable glove and resealed all of those ugly cracks. Those cracks not only look ugly but they can also allow water or liquid intrusion, and nobody has time for that. 

I have seen different ways to remedy this, however, I believe using the matching grout to fill the crack is the best solution instead of using a silicone “Dap” style filler and here’s why:

• Dap may be used for a painted wall/countertop edge but not backsplash/countertop edge

• Dap may not bead smoothly over the existing grout

• The white dap will stand out like a sore thumb

• It looks cheap. (There, I said it.)

It is important to maintain little things like this. When you go to sell your home, you don’t want people working about intrusion, cracks or the appearance of deferred maintenance. If they can see a crack, they may say “what’s behind the crack that I cannot see?
