what would you use for this job?

[TonyUK]

I have two 8 ft polystyrene roman style columns that are to be marble plastered.
What would you use on the polystyrene as a base to plaster to? The only thing i can think of is plasterers mesh tape,but that only comes in 48mm wide. Can anyone suggest what i can use to make sure the plaster stays on the polysterene ?

Many thanks
Tony

You can get hessian that will do the job, you'll need to ask for the width you need

for god's sake dont' say something like that...!

Yes, you can but probably be better of attaching galvanised mesh over surface, best method is with wire , obviously polystyrene has no suction so you will have to apply bonding coat to mesh, then skim.

i'd use a big dollop of 'delegation' and let whoever's gonna do the 'marble' plastering make the decision...

im sure the backing coat would have to be resin based over ploy

Does sound like a hell of a lot of faffing about for two faux pillers, Very best of luck to you

You could try mosaic tile mesh, sounds tricky to tell you the truth though never done anything like that,

Thanks for the replies everyone, what about using wire cloth? maybe 0.5mm, perhaps that would work without affecting the integrity of the sphere?
Everyones thought appreciated.
Cheers
