I just watched a Hometime episode where they installed a full granite backsplash. They used dabs of silicone to attach it to the wall.

We have a full granite backsplash. The installer used silicone to attach it. Although, when they were installing it they didn't use enough initially and one portion of the backsplash fell and crashed onto the countertop. Make sure they put enough on the wall to hold it.

Really!? Just silicone to hold all that weight? Is this 2cm or 3cm stone?

Fori - we are doing the same but several months away still. Can you post a pic when they're done? My DH has fears of being crushed some morning while making scrambled eggs :)

Yeah...umm...EEEEK!

I don't know if I want that thing held up by PAINT, which is all the silicone can stick to. I have tall cabinets on either side and can stick up a few decorative doodads to keep it from flopping forward but I'd rather not!

So um...it's going up in a few hours. Can you promise me it won't fall? I guess I should be extracting that promise from the installer.

Wish me luck?

I have a full sheet of quartz going up behind my range hood tomorrow and will watch this space to see if I need to be (more) worried than I already am!

MY KD suggested a piece running from the back of the cooktop to the crown molding. This would be attached to a wood wall. A plywood extention that the cabinet company installed to extend a wall. I, too, was worried about what would securely hold the granite slab on the wall. I'd hate for me OR my induction cooktop to be smashed by a falling slab.

Is there any trim moulding where the full-height backsplash meets the sides of the cabinets (assuming you have cabinets on that wall). If so, and if that trim is securely attached to the cabinets (pin nailed, stapled, etc.), it should hold the backsplash slab in place - especially if it's "glued" to the wall as well. It just needs to be kept from falling forward. If there's moulding along the sides of the cabinets, they probably overlap the backsplash slab by 1/4" - 1/2". I would think that would do the trick.

Here is my full height granite backsplash held with silicone on the wall behind it. It's been there about 2 years with no problem and no extra supports. It sits on the granite counter with a bead of silicone to prevent any moisture going down behind if I should spill something.
It reads a little greenish, which it isn't (not a very good picture).

This is a beautiful kitchen! is your backsplash granite 3cm thick? We recently installed full size quartz backsplash and was a bit worried about the weight of backsplash plus countertops on our kitchen floor (about 130sqft with total 80sqft 3cm quartz). Did you have any extra support on the floor? Thanks!

The silicone doesn't hold it up, it rests on the coutertop below. The glue only has to keep it from flopping forward, and there's no stress on it that would make it do that. It will be fine.

most of the backsplash still sit on the edge of countertop because of the non flat wall. The contractor needs to maintain the level between two slab so there is even a few thin wood plate behind the backsplash (so it push the slab forward and level with another slab)so silicon wouldn’t work at all.
My concern on the weight is because we notice a little spot buckle on the hardwood floor (at the corner where two slab meet) after the full size backsplash installed, the total backsplash is about 19in high running about 22ft long. Not sure if the buckling exists before the backsplash slab was installed. We check the joints and subfloor from basement, no visible seam or gap was found.
We are planning to have a structural engineer come to check but are still struggling finding one in our neighborhood…
