Rendering a silage building wall

[RWG Contracts]

Has anyone ever rendered a silage building wall?

What did you use?

Has it lasted?

I've priced to do a job and now I'm questioning my thinking

 

[multi power]

Not me done it personally but all ours at home were rendered, no different to anything else, they would have been done 60/70s and still going fine when we sold in 95

Rendering on to shuttered concrete or a block wall?

I'd be adding some epoxy if I were doing silage walls,trouble is its feckin dear.

Next doors shuttered walls were rendered when new in the 70s,think it was because the couldn't get a good finish.

It's old atcost panels

what are rendering onto,i have found sbr to be very useful as an additive and a key for suction

how big are the panels? movement might be an issue

 

[SilliamWhale]

Why bother rendering them?

They'll be 15' x 5' I think

It's rendered now, I'm guessing it's because them atcost panels are hollow and the skin is only relatively thin so it's to try to stop the effluent eroding the panels

its abonding agent,about a tenner a gallon. it will slow the setting of render down ,good on hot days,mix it up with neat cement to form a bonding coat to help render stick

SBR is a waterproofer and bonding agent. One of the better ones.
It is very much like the expencive liquid latex tanking solutions.

No experience of rendering panels and I could never claim to be a plasterer but I've used Weber Rend-aid in the past as a base coat when rendering smooth surfaces. Mix it up, slap it on and texture with a paint roller. Sticks like sh1t to a blanket.

I have also heard of people applying SBR with a tyrolene gun

It wouldn't be just SBR as it is merely a liquid.
For keying to a poor, or over smooth surface, you can splatter coat. Mixing 1 sharp sand to 1 cement plus admix such as SBR. This is then 'splattered ' over the surface, and will leave a strong textured surface to key render onto.

I had some done in my calving pens Rob, I got them to use AS moist sand, at about 3:1. I wouldn't use PY sand because it looks too crumbly to me.

I think it would stand up to silage, its just if someone's too keen with a loadall.

Just plasterboard and skim it! Bit of paint and job done...!

Oh....you're looking to put silage in it?! You should have said before...!

In that case wouldn't a good coat of bitumen painted on be better?

He wants it rendering so that's what I'll do. I'm happy to render it just wanted to make sure I hadn't missed a trick of an additional material to add to make it a proper job
