Marble Question.

[Shack]

I just got about 200 square feet of Italian 7/8th inch thick white polished marble (with grey squiggly though out it). It came to me in 6 4’x4’ slabs and some other sized pieces. Its very nice stuff and I am planning on using it to build a nice serving area, bar next to family room down stairs. The thing is, it has ¾” plywood on back side. By the looks of it, some type of epoxy is plopped down every square foot on back. It does create a slight air gap on back side of slab and plywood.

My question is, (with out knowing what the glue is) what could be applied as far a solvent to remove glue and plywood. If you try to pray apart, marble will crack. This is some tough stuff. What I can see of it, the glue is yellow in color.

I could work around this plywood , but would like a fresh back side to work with. I also plan on cutting pieces to the size I need with the water jet we have at my work. The wood could be an issue when cutting on the water jet.

I am finishing the last of my basement and am about a week or so out before I would need to set Marble.

Does anyone know how much marble goes for a square foot like this?

Thanks

I would start with chisel and hammer to get most of plywood and glue off, that may be good enough to work with then. Other wise just try different solvents to soften and peel off the glue. I haven't found a solvent yet that will take off glue ( the kind you are working with ) with out having to scrape it also.

A heat gun could work also.

Thanks for the info.

I am still wondering what solvent (name) could be used. The glue is old. From between 20'-40's was when it was applied. I was talking with a buddy this morning and he brought up an idea which would involve the longest Saws all blade made and from the other post in another forum area I found I could use a router to cut out the loosen chunks. I would still have to remove old glue after.

I also have thought about just leaving wood on and working around it.

Shack back then most adheasives were animal based products,some were needsfoot,linseed oilbased like linoleum,so then If ya have to, something that will breakdown proteins may work???

But I'd still go with my original post in exp.info
