I want to know where I can purchase the glass mosaic tile that I saw on one of your shows that needed no adhesive. My sister used joint compund to make a back splash for me, now I am very tired of it and want to put up glass tiles. Would I have to sand off the joint comppund? I hope not, the glass tile would really give the kitchen a touch of class. thanks Debbie. firstname.lastname@example.org is how you can reach me.
