## Questions & Answers

**Q: How do I pick between sanded and unsanded? The spaces are 1/8”**
A: General rule of thumb- sanded for gaps over 1/8”, unsanded for gaps under 1/8”

**Q: matte finish or shiny?**
A: My experience:  goes on shiny and dries to more of a matte finish.  I also found the color (frost) caulk was a good match with the frost colored grout when dry, i.e. the grout does get a shade darker when wet... but dries to match the caulk (caulk seems to have the  same 'darkness' level when wet or dry.
