Knocking off Weber through-coloured external render

[jacjwc]

Hi, I am looking for advice

I have just bought a brand new house which is rendered with Weber through-coloured external render [rough cast finish]
The render was applied in very wet weather and has slumped in parts.
The builder has agreed to knock it off and re apply.

I am worried that in knocking off they will tear off parts of the block work wall & make things worse.

Is that likely or is it an ok thing to do ?

Thanks

If its sound just re top it

As it is more likely to be one coat then it should be ok. But you will need a coat of Weber rend-aid the second time as the block pores will have been filled in giving no key.
