Hi, I am a total novice and have tiled a shower enclosure using the following tiles
They are extremely textured and layered 1cm high marble strips layed directly on eachother so I cant grout between each mosaic piece, there was a plastic sheet on the back. I covered the plasterboard in a thin layer of grout, let it dry and then used more grout to stick the tiles on.
I'm not sure which sealers to use, after reading many posts I think an impregnator - Lithofin or HG. I am going to silicone the corner joint, and around the shower base and cubicle. I was unsure what to use between the small tile joints (on the verticles where the edges of tiles meet - they are all laid directly on eachother so no grouting on horizontal tile joints), some recomend unsanded grouts, others epoxy, some latex, silicone caulk etc.
the more I have read the more I am confused!
