I'm having problems with my grout
You would think by now , I would have learned everything there is from all the experts here .... but this is an on going problem I have to ask about.
When I grout ,I see teeny "air holes" in the grout lines. I fill them in by swirling the grout , so it gets in there on every angle. What causes this ? Is my grout too thin ?
Then -- I have the problem of my grout sinking - it's not even with the glass . Am I wiping it off too soon ? The grout lines seem caved in . What am I doing wrong ?
( I'm using Mapei ) It's aggravating !!!
