Blown plaster

Posted by Margot Reynolds, on Fri 28 Aug 2015 11:34am

I live in a 1900s terraced house. 4 years ago had hall and stair walls hacked off and plastered - then painted once we'd given it plenty of time to dry. Over time large areas of the plastering had blown so had them re-plastered. Withing days the same thing has happened again! Can you advise as to why and what would be the next step please.

The plaster needs to come off , & the wall needs prepping first with Pva so no dust is on the wall , then needs to be done in sand & cement render then skimmed smooth , should have no trouble with blowing G, branch plastering
