Summerhouse render - what to do?

ChilliBob

Guys, our summerhouse render has started to come away a little after some renovations, and today our ever helpful son ripped off a massive bit!

I was considering just filling the areas that needed it but unsure now.

It's only the front, 7m wide and about 2m heigh - of that there's a door and two large windows 120 * 150, so there's not tonnes to do.

If I get all this off, like peeling wallpaper off it seems, can I just somehow seal what's there then paint with masonry paint?

It's not clear to me what the yellow stuff actually is, and what it would take. It's also not clear what the grey stuff is, is that just a paint skin (I know it's textured Dulux) or is that paint and the render?

I've got a pretty decent knowledge of internal decorating and stuff but not much externally. 

Any help much appreciated!

The picture would have helped!

It looks to me like the yellow material is the render and the grey is a painted coat of Sandtex masonry paint or similar.
Hopefully an expert will be along shortly.

Looks like it is a layer of plastic paint that has peeled off leaving the render behind intact. I'd let the helpful son peel a bit more off so that you end up with a neat square with clean edges. A sharp knife will help to give you straight edges. Then paint with a masonry paint.

Ah, this could be great news, as the textured masonry paint wasn't our ideal finish - we preferred smooth.

The fact it comes off so easy (by the looks of it) make me wonder if I do just paint straight on to it, (the render that is, not the old paint!) or if it needs something else?

It feels akin to an internal wall that's not been mist coated.. I do have tins of Gardz and Peel Stop at my disposal too.. Just a thought!

Something like Everbuild Stabiliser 406 first.

See how well it soaks in. If the surface is very absorbent, apply liberally. Brush it well across that (and any other) cracks too, until it stops drawing in.

Sounds odd, I just put a wet finger on it, and yes, it changes colour, so, tis porus. 

I have peel stop so I'll probably use that. 

So I guess it comes down to whether I try to just have a large patch, which will look different as I'll have to sort of skim fill then try to texture, or, rip the whole lot off, as best I can.

I'm thinking the latter at the moment

Cough.

Stabilising solution

Not sure what you're getting at, but Peel Stop us a stabilising solution, yep, there are others, cheaper, more expensive but this one I happen to already have

I stand corrected - and informed I'd assumed it was just an anti-paint-peel product for internal use. But it's seemingly a full stabilising solution too. Cool.

No worries, I only found that out yesterday too from a couple of videos and a bit of research, always good to use what i have. 

Seems that peel stop is quite a useful bit of kit according to some blogs
