Tile Mount

[Larry01]

Hi Everyone,
I know there are loads of threads on this but I have some questions about using particular materials and am concerned about bowing and off-gassing.

I’m planning on mounting 7mm H ceramic tiles (no grout) to an 8mm marine ply, backing panel using E6000, then framing under AR70 glass in a 27mm deep moulding. Customer wants a window mat cut with a 45mm boarder which I will have to glue to the ply backing (thoughts on best adheasive for this?)

Tile area is 740 x 445mm, backing panel 830 x 534mm. Boxed tiles were 3.9kg, so estimating finished piece around 3–4kg. It will hang from Wall Buddies attached to the backing, not the frame.

I’m considering 8mm marine ply, sealed front/back/edges with a water-based polyurethane before adhesion. Has anyone used 8–9mm ply at this size/weight long term without bowing? The gold frames my customer likes are around 27mm H and I need to allow for a spacer so there's not much depth to play with.

Any concerns about adhesive or sealer off-gassing behind AR glass once fully cured? The glued down matboard lifting off the ply backing is also a bit of a worry.

If needed, I can move to a deeper moulding — was just hoping I could keep with their frame preference.

The WCAF framing conference was this weekend, so it might be Monday or Tuesday, before some framers in the US see this.
Glad you posted, as I'm also curious about it.

When I have mounted tiles in the past, I have used Acrylpro Tile Adhesive, or Roberts 5900 Ceramic Tile Adhesive. I have never had a complaint about off-gassing, though the majority have been done without glass.
I am not sure how well E6000 would work.
8-9 mm marine ply should be fine. Marine plywood tends to be strong in my limited experience.
If the matting is being attached directly to the plywood, wood glue and weights, or sat in a mounting press over night would work well.
I would mount the mat, then the tile, and wait a few days before installing into the frame.
If any off-gassing occurs over time, you can always open the project and clean the glass.
