how long to wait for grout to dry
Do I need to wait 21 days for grout to dry before using my shower? Hi, I&#39;m currently tiling my bathtub/shower surround with 12x12 porcelain tiles. I&#39;m using Mapei Keracolor S Sanded grout with Polymer for my grout. I picked it up from my local Lowes hardware store. My main question is how long do I have to wait for my Mapei Keracolor S Sanded grout... Source(s): wait 21 days grout dry shower: https://biturl.im/qfwPs.
