we are installing kitchen countertop 12" granite and trying to decide between epoxy grout or polyurethane based quartz grout in a 1/32" groutline (by Star Quartz). Which would hold up the best for our application? Question 2..could expansion and contraction an issue? thank you

 

Dear Norma:

I never even heard of that particular grouting material by Star Quartz before, and therefore I can't make any comment.

Epoxy grout is not exactly what I would call a user-friendly product, though once done is indeed an excellent material for the purpose.

An excellent product for grouting kitchen countertops and that's user-friendly, is color-matching latex-based caulk. It has the same advantages of epoxy (stainless and shiny) but it is much easier to apply and to clean.

Now remember, it's never too early to think about the proper maintenance of your stone. The issue of what you'll be doing day in and day out to your stone is – as it should be intuitive – vastly more important than its sealing (if and when possible and/or advisable) and it's all too often neglected. As you can tell by reading many of this site's postings, you're not likely to get good information about routine care from your dealer or installer. Don't become another statistic!
