Can someone advise on what adhesive I need for sticking a steel fire trim to fireproof render? This will be the only means of securing the trim in place; I'm not looking for something that's only a sealant.
Someone recommended Everflex Heat Mate sealant, but I don't think this is the right thing, given that it's marketed as a sealant and more importantly the manufacturer says it's not recommended for stone. (<http://www.everbuild.co.uk/heat-mate ).
I'd like something I can put a couple of beads of onto the three sides of the fire trim before fitting; hold the trim in place with some wood or whatever; and then remove the wood and the trim stays where it is! I know of several products I could then use for sealing, but it's the sticking I haven't worked out yet!
Many thanks in advance.
