New to forum. Rendering over steel, Advice

[Doncs]

Hi, Just joined as I have a few queries. Done a bit of platering before, got a newly blocked wall to plaster which is about 6metres long, in the middle, theres a steel post which is around 5 inches wide. Can I plaster over it? if so, does it need to be prepeared in any way? score it with a grinder etc? Cheers :RpS_thumbup:

welcome to the forum

no render will not stick to steel

use some expanded metal lath fixed to blockwork either side
with screws/washers
you should not need to fix into steel at that size .

sure someone else will be along with another idea.?

quite like that idea, thanks

I would add,put some building paper behind the mesh to creat a slip plane. Use less gear then.Also make sure this is not a movement detail in the construction as your may need to follow this in your finish.If its internal you could dat and dab the wall and bridge over the steel eement.
