slate patio grout cracking problem?
Could I be just too picky? I don't do cement work and don't know but in between the stones I can see lots of hairline cracks, the guy doing the job says it is normal for the hairline cracks, do you know of this problem or is it even a problem. I don't want to be a problem unless i know about the cracking on a job like this??? Thank You very much in advance for your time with my question,
