This is 1st coat of Min Wax floor varnish on top off Annie Sloan Chalk paint on top of ceramic tiles. Only place peeling is in certain grout lines. Tile portion is fine. Did I leave to much residue varnish in grout lines and it dried and cracked? It's not everywhere just around these X joints mostly. Fix? Light sand and apply thinner coat of varnish 2nd coat?
Annie Sloan has a site go to it and show them.
I would say the chalk paint reacted with the grout. Sealing with varnish just caused the reaction to crack through the varnish
Did you let the floor dry completely before painting?
Problem was corrected by switching to Min Wax Oil Modified Water based Varnish after a light sanding. Worked great! Thanks all for the suggestions
I would guess there was a sealer applied to the grout which did not work well with your new finish. Not sure how to correct??
