Byson units

[PeterMcC]

Hello all,
This is my first post, I have been asked to plaster byson units in a carport. I have plastered these before in apartments or flats but as on this occasion they are outside bonding doesn't suit. Has anyone used anything else ?, K-rend or something? would be a bit messy with sand and cement as its overhead but that may be the better or cheapest option, thanks in advance for any advice.

Thank you. They are huge concrete slabs with a very course finish .

We talking about the precast concrete planks?

 

[PeterMcC]

I think so. Is there anything that would suit to render it. Ie it's like a scudded ceiling in an open carport so it will be affected in some way by the weather

If I was doing it I'd scudd and sand and cement it but I'm a dinosaur! Hopefully one the boys who know about modern renders might be along in a bit.

I am not too clued up on renders but if it was inside I would strap them and board, can you do something similar with a cement board?

 

[malc]

what finish is the render to receive?

Can you hammer fix a MF grid up there and cement board it ?

Otherwise I'm with pug, scud it and s and c. Messy old job though
