Granite Slab

[Fredo]

I've decided to try to take two slabs of granite 3/4 thick and laminate them together. I'm thinking that "IF" i can get a good tight seal I should be able to use it as a tooling table-top without craking it. I'll build a strudy

suport table to make sure noting flexes. I'm going to frame the perimeter in so they can't slide on each other. 3/4 granite can always be found cheap on craigslist. For instance I'm heading out to pick up a piece that 42x 36 for $25. I'm going to cut that in half and glue the two halves together.

What type of adhesive would you use? I'm thinking I'll go with a construction adhesive like liquid nails.

Your input is appreciated

FWIW: I would use a good epoxy type of adhesive. Mike

Mike, I thought about that but feel once epoxy sets it becomes brittle. Wouldnt that allow for easier cracking?

If you bond two thicknesses together and do not get your adhesive to "connect" on both pieces of stone completely, you will get the same effect as though you used one piece of 3/4".

I would look into maybe the mortor they use for laying tiles and such. Or if anything the glue you use for tiles that are glued to walls and such. I think if the granite is layed rough to rough this may work.

Keep it simple, use contact cement. CC has some flexibility even when dry, and it can easily be spread thin , and evenly. I would think with a grout type material that it might eventually start crumbling out of the seam.

Contact Cement, BRILIANT!!

Hi Fredo,

There are several products designed to do just what you are needing. If used correctly, the stone will break before the adhesive will seperate. These adhesives remain slightly flexable, unlike some epoxies, which get very brittle. Here are a couple types to look for,,, they should have them at Lowes, or Home Depot. http://www.itwtacc.com/products/index.cfm?product=Mason Bond&subapp=Masonry%20Adhesives http://www.brickstopcorporation.com/brick_html/brickstik.htm

Hope this helps,,, Ed the"BearMan"

You guys are dreaming if you think contact cement will hold the stone together on the rough side. It needs a smooth surface to make the bond.

I say this since I have bonded thousands of feet of laminate and wood plus many other substrates. I used to build Commercial Cabinetry.
