Hi. I'm building a fire surround using fire resist MDF. I know I can't tile direct onto the MDF, so I 'primed' it first with contact adhesive, let it dry for 2 days and then set the tiles. I'm using universal adhesive/grout (not good I know) and 6x3 wall tiles. Trouble is that I've tried twice to tile the surround and each time it looks like the adhesive has not set. I left the tiles for 4 days before trying to lift them but the adhesive is still 'wet' and easy to scrape off. Do I have to wait longer for the adhesive to set? Would a coating of PVA over the contact adhesive before tiling help? Cheers Brad
