your argument is really going off track, im sure people will see ive tried to reason with you but now im getting random interrogation questions that have no relevance to earlier posts, I hope the OP got some value out of my first post as i gave realistic advice, Joe this is my last reply to you...

Right then Joe your twisting things here, I do not know if modern renders will last 70 years or not ! maybe they will maybe they wont ! I have no proof to say they will or wont either,your asking the wrong person. my main point is that your claiming that you...

lol just as I thought your claim was just a whim and now your trying to turn it around, nice try ! :wink:

what makes you say that ? is there some information you know that your basing that on or just a whim, its very easy to make comments like that on a forum but without any real evidence its pointless, unless you have evidence to the contrary ! have you even used any of the modern renders to base...

Im not bragging TBF thats a bit harsh, If the stuff they used is the 1950s is so good why dont they still use it, my guess would be yeah its hard but in turn this will make it brittle to movement, plus i guess its not as breathable as the modern renders :lol:

The trouble with sand and cement render is if mixed wrong it can easily crack, obviously though done right and it will last for years but there is not many people who mix it right and to be honest why use a old product when there is so many new modern renders on the market that is premixed...

The trouble is that the wall is a retaining wall and may be holding water behind it as it does not have any weep holes from the picture I can see ! this might be why the render has blown as the water will soak into brick from other side and then get behind render, which is never good ! might be...

A late post I know but no there is not much shrinkage in 7n blocks as they are very dense and do not suck in a lot of water ! Martin

You can get it for as cheap as £8.50 + VAT as far as cost is concerned K-Rend and other "monocouche" renders can be applied and finished a lot quicker than s&c render (time is money) I would say it only cost about 15-20% more than s&c and painting, and finally K-Rend is a far superior product...

John you can put k-rend on with a trowel (hand applied) but cannot trowel finish it, it needs rubbing up with a special nail float.

can porous render cause internal mold on a solid brick wall ? Yes if the render IS porous it can let in water which in turn will cause damp! I have recently had my chimney re capped and flaunched as it was leaking bad. Gutters unblocked and cracks in the render sealed. Since all this...

Can you not contact the insurance company who the house build is insured by NHBC or similar ? Also contact weber and mention this post, im sure they wont like the publicity that there produt spalls when using beads which they dont condemn, its not the product as its a good product if done right...

What about the thickness of the render ? It should be at least 16mm ! If is not then the job is wrong and the builder should put it right !

If Done right one coat render can look better than traditional render, but it needs to be done right !

Looks like they have used the wrong beads, your correct the minimum thickness is 15mm even on corners, you can get the bead from b and q or I use these ones: http://www.directbuildingproducts.co.uk/details3.php?id=1537 The builder is at fault make sure it gets put right ! If the...

No worries you can contact me on 0786631645, but make sure its after 530pm please

LolI think he should ring the weber technical helpline and ask them as they are very helpfull !

Yes

No dont scratch First coat !

. Although you put it on in 2 passes its classed as one coat because it sets as one, you cannot put a coat on one day and a coat on the second day because its designed to go off...
