mosaics on curved wall

I'd think Kerdiboard may run into a problem with some glass tiles unless you choose to use a modified thinset. John B? what do you think.

If you prefer a bendable cement board, why not something like PermabaseFlex? Cement board with those foam beads, and it bends like a hose.

The big word here is SCHOOL
When ever I have been on school projects the specks have gone beyond what is necessary . It is something I would never try without the blessing of a architect or engineer . You will have to propose a bulletproof plain to get approval .
To deal with spacing the radius is not that strong but a work table can easily be built to reflect the curve .

Your feedback is just what I was looking for.

One thing I am curious about, does it matter so much if the installation is concave vs convex? In this case it is the concave side of the curve, but I'd like to understand if there is a difference WHY. And with an 8' diameter, the curve should be gradual enough.

I think the point about a sprinkler system going off is valid and yes, this project needs to last.

I'll call the permabase flex company, and will also give a call to Henry Rothberg on Monday and see what he thinks.

Not to overdo it, but this forum is just the BEST!

Hi Cindy,
Were I in your position, I would lightly sand the area to be tiled and then remove the dust with vacuum and a damp towel. I would then skim the area using Laticrete 254 white modified thinset, mixed thin and spread with a drywall knife for a smooth and durable bondable surface. I'd then use either Laticrete's 4XLT or their new Glass Tile Adhesive for the bonding bed.
