Weberpral M Rendering Issue

Hi, first time at rendering with Weberpral and as easy as it seems to be to apply I am having these rings appear in my walls after applying a scrape finish on it. Can anybody advise me on how to avoid this? Is there anything I can do to get rid or will I have to redo the walls affected? With Weberpral, can I just go back over the wall after it has fully set or will I be required to remove the affected walls? Thanks for any help or advise

You've scraped off all of the 2nd coat and the 'inner' of the halo is your 1st coat

Mistake
Dogshit
Do again.

Possible to coat over, depends on metreage and beading

thanks, so essentially I’ve scraped too much off or left those areas too thin on the second coat then? it’s not a particularly big wall, so I’m fine with going over it. Approximately how thick would I need it to be on a next coat to be able to scrape off? Will I need any PVA before going for another coat with the wall being set? Thanks

Not PVA

Only time I've had to do it was when a scaffolder damaged my finished work (when taking it down) around 2006,

Contacted K rend who spec'd to SBR the wall and coat again. I think it was 1-1 mix then two passes again, around 18m²

Went well and still up now.
 
Quick question with the SBR. In this case should I mix with cement and apply the render on top or mix it in with the render itself? Thanks
