Question on Indirect mosaics grouting and WIP
I'm working on my first big indirect mosaic , using Cinca porcelain tile and gluing it to kraft paper. I'm ready for grouting now but have a question for any one who has done indirect's before.
One set of instructions says pregrout before you glue the tile to the substrate. Then after it is firmly in place, grout a second time. Another set says just grout the regular way, after it is glued to the substrate. So, I am confused of which way is best..
Here's a pix of where I'm at
