A different grout question
I think I have mentioned that I am doing some mosaics on old fence wood that I nail together in different shapes.
Anyway, I was thinking I would do some "painting" sort of with grout to get some texture and just for something diffent.
Should I use grout or thinset on the wood to do this.
The wood is not sealed, but it could be painted either with acrylic or enamel.
Sorry I have not posted pictures, my camera is camping out at my son's!
