Rendering directly onto OSB3?

[dabomb3k]

Hi guys, I've had a look but in getting some conflicting information ..

I have a shed that has 4 brick pillars holding the roof up, the sides are brick that I'm going to render. The front and back are old tired and crumbling wood...

I want to replace the front and back as cheaply and quickly as I can so Im considering replacing the wood with OSB board and then rendering it to help with water proofing etc....

My question is can I just mix up some rebder and put it directly onto the board???

Thanks...

Short and straight to the point... What's my best option?

You could cover your boards with roofing felt then tack on some ex-metal , I would put two layers on one vertical and one horizontal then scratch it and then when its set for a few days throw the float coat on. Always tack ex-metal from centre out wards and use plenty of p/board nails...There are other ways which the lads might do it but that was how I have done it before..

Thanks, sounds like a lot of time and expense.. Think I might just replace the wood panels with fresh an just treat it 😂
