you could take the bad bits off patch back in and put a 1.5mm silicone render topcoat over the top in white

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:

The builder is at fault make sure it gets put right !
If the correct beads are used then the corners want spall like yours.

If Done right one coat render can look better than traditional render, but it needs to be done right !
had the Weber rep out today who would only say "they are not the beads that we would recommend", but they are not wrong.
Looks like I am going to have to pay out of my own pocket to fix this mess.
All the builder wants to do is patch it up!!

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 !
I mentioned all of that, and the Weber guy would not commit himself.
He says that there is an undercoat type thing, and that MAY be part of the 16mm. Seems happy that it is 15mm in centre of panels, but is not bothered that it spalling away from edges. The bead that has been used will only allow 2/3mm for thelast 10mm as it approaches the corner, but they have simply said they will patch it and monitor it.
Dont know if its worth getting a lawyer involved. According to them a rough cost to replace would be £7000. It might be cheaper and easier just to redo it myself.
I think he was scared to say too much in case it upsets the builder (his client!)

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 but they should say if its been done wrong instead of trying to keep client happy. This is a exert from one of Webers pages about beads : For scraped renders, some render may spall away from
the nose of a standard angle bead profile during the scraping process. Proprietary Ysection plastic beads are available and form the best solution, after traditional
methods, by promoting an even thickness of render right up to the corner point.

Similar to what has been described above, it has been suggested that the corners could be patched up, and the beads replaced, and then the whole thing covered in a acrylic / silicone render in white.
Does anybody have any experoence of this, and would you recommend it?
Obviously this saves the cost of removing all the blue, but is it a cost effective solution?

it can easily be done in acrylic its about 45 to 55 a tub which will on mono cover about 8m2
As above, you could go down the route if all the render is sound.
If you go down that route, make sure you get someone approved to use the product. If you phone up the company they will have approved contractors in your area.

Have the NHBC coming out to inspect this at the end of January.
Heres hoping they agree that it has been applied incorrectly.
More has crumbled off in the last few months!!
If no luck with them then I will be left to sort myself sadly!!

good luck with that let us know the outcome
firstly, sorry to hear this is still ongoing.i was hoping you would have it sorted by now.
are any of your neighbours render in a similar condition? if more has crumbled off then there is absolutely no way this has been applied correctly. weber comes with a guarentee but i dont know if this covers you as the renderer quite clearly tried to save a few bob
