Advice required please!
Covering a fiber glass sculpture in circular mirror mosaic tiles for an outdoor art trail. I was advised to use mirror adhesive to prevent mirror backing degrading and began applying tiles by individually applying adhesive tile by tile as the surface is uneven and some needed more adhesive to level out with the surrounding tiles....now I discover that the cement in grouts can degrade the mirror backing and some of the tiles that went on first aren't completely coated with adhesive. Are there any grouts/epoxy mixes that are less likely to affect the mirror backing (mercury coated) I have tried contacting two different grout manufacturers but getting mixed messages. As the sculpture needs also water/frost resistant grout and the joints are between 2-10mm because I'm using varying sized circular tiles. Any advice appreciated as I need to find the solution asap!
I have seen the acid resistant Epoxy grouts used by Mapei but due to joint widths they weren't advised and the Ultra colour was recommended though that's a grittier mixture and cement based I believe but doesn't cause efflorescence..I'm not sure which of these causes long term mirror backing degradation?
Had I known the grout risk I would have covered each tile back fully with adhesive as I have done with all subsequent tiles since I found this out.
