I had someone help me diy remodel a bathroom, and the grout job has some issues. Mainly there are tile spacers sticking through the grout in a few spots. They were the leave in kind, but some weren't deep enough.
I have a multi tool with a diamond blade, so I can remove the grout. My question is can I just do the section of joint where this issue is? Its 2x6 subway tile. Is new grout in small secrions going to adhere ok? #home source
