I`ve seen glass mirror tiles plastered over coated with PVA thick .left to dry, coated again thinner, next day and multi finish trowelled onto the still tacky glue.........T`was done by an old plasterer....I`ll let you make up your own mind

i know someone who plastered over tiles,lol,still up,i wouldnt try that though.

well i got a grinder on it and roughed up,put 3.1 pva on,left to dry and multi finish tomorrow,

someone has done it before,the plaster was still on,but not very good,was put on the smooth finish,i think the previous job was not prepared very well,
