Cheap Bath Mats

I try to get the look polished pebbles "cheap" but thought the grout would add some authenticity while keeping the head lighter than using real stones.

Sounds cool. How about using a clear silicone adhesive?

I think so ........ MDF is probably already sealed so that the rest is to find a job right glue for all hands and feet pushing :)........ luck.

Unless you use an epoxy grout, which is a bit of a turn, you are able to wear certain pieces of grout morning because it loosens and splinters off.
