i dnt need to i have a misses for that, its all fair and well wen i say something that you could use then wen people try and have a laff thier wankers and shud have thier posts deleated if we all took everything seriously this would be a very borring place
 
6 of one half a dozen of the other mate my point was wen he wanted something there was ideas and help there then people try to have a laff and were suddenly wankers and should have our posts deleted
 
I've got a mate who used newspaper, Daily Star I think it was. That was 5 years ago render still rock solid today.
 
Well, saying that I've just looked online and you can get it for £35-40 a roll. The stuff we use is brown one side and black t'uther. Don't know if its any different. We use it as a floor protection so go through loads of the stuff. Luckily I don't have to buy it.
 
Not sure about putting building paper under lathe, it'll give less mechanical key and defeat the purpose of using lathe to strengthen render that is sticking to brickwork.
Effectively a 'floating' render coat
 
I'm going to be fixing Riblath to the brickwork, no building paper if key is required. Mesh in the scratch.

Any1 used Riblath before? how many coats of render required?

Thanks

Celcon recommend using building paper under riblath or similar, when rendering onto their 4 newton blocks. Not entirely sure why, but as we all know they are very prone to stress fracture and I suppose they see an independant/floating render as less likely to crack in the same place. You'd want a load of fixings in the lath though I'd imagine...those soft blocks are shyte at holding anything.

i would think that the suction from the blue block would dry the pricking up coat out to quickly. we always roll a coat of external pva on the blocks before we rib lath.

Yeah last time we primed with SBR, but if I rendered any of that crap again (and i hope i dont have to) I'd probably use Microgobetis.

The fact it creates a 'floating' render as you put it is it's main advantage and there would be no problem with the amount of mechanical key Eddie.

I can see what your saying Andy but if the brickwork stresses and moves independently from the render it will defiinitely crack. The lathe would be fixed thru the paper by mechanical fixings and when this cracking does occur you're gonna have massive freeze/thaw issues with water running down the back of the render.

At least if you've got mesh reinforced render directly bonded to the bricks it will effectively strengthen the brickwork.

Best bet would be to underpin it :RpS_thumbup:

the only time we ever use SBR is if we are laying a very thin floor screed ,under 1 inch. for render we use a external pva.
 
Ive always used building paper Eddie though i must admit the last job i done with EML was about 20 years ago but that was the way it was done as for external PVA, no such thing no matter what the makers say PVA reacts with alkaline which cement is, well thats what the scientists say anyway,
 
Oh yeah, all the Andys ganging up on me :RpS_biggrin:

Someone said it earlier in the thread, but try hacking off render on rib lath bonded straight to the brickwork - its like trying to hack off them white Victorian tiles stuck on with s/c in old bathrooms/ kitchens.

I worked for a firm called malabright (gibbo did aswell) in the 90's and the spec on the job was building paper, EML, bond, skim. Obviously it was internal but the building paper on this refurb was to stop the painted brick underneath 'contaminating the new plaster'. Anyway, tap it and is sounded blown, hit an office desk off it and it was like an eggshell.

Some years later, the site agent off that job was cont manager on a Laings job I was doing the external s/c on. Insisted on building paper under mesh n render on externals. It failed miserably within 3 yrs
Each to their own in different conditions I suppose, every job is different
