DIYer Question on glass tile over marble Fireplace surround
I found this forum and think it's great that there are professionals and experianced DIYers out there willing to share thier knowledge and experiance to the rest of use! Let me say think you in advance for any help you all can provide! We just bought a new house just south of Richmond Va, and I'm wanting to change the black marble(?) surround around the gas fireplace to a glass mosaic tile. None for the mosiac will overlap or touch the metal so I don't think I'll have a problem there with heat.
A few preliminary questions that I have are
1) can I tile over this marble (it's a stone that is slick as glass- but it's not glass) without using a backer board
2) What product would work best for this kind of application (ie thinset vs mortar and sanded vs unsanded vs epoxy grout)?
3) Would it be better to rip the black marble out first and install backer board in its place?
I've done simple bathroom and foyer installs but I've never worked with mosiac or glass tile before- uncharted territory for me. I've been trying to read other posts and am learning alot but hoped this could help cut through days worrth of reading.
The glass tile will go up the sides and across the top while the floor will be either a ceramic or maybe a stone- not exactly sure what would look best for the floor. Any recommendations would be really appreciated as to what might look good for the floor. There is an access panel for the pilot light beneath the fire box so building up from the floor isn't really an option.
