Had a big problem arise on a thincoat job we did 2 years ago.
System was
Slurry
10 MM base in two passes with mesh
Primer
Thincoat

We been told that it’s because of cavity wall insulation
Anyone else had problems with cavities getting filled?

What make is it?

What were the conditions like on application day?




I've done retaining walls years ago with thin coats that are still ok. And I knew they still had some moisture passing through system before starting and still now.

Was fassa system

We had a lot of rain throughout the job at basecoat stage. Dry week for topcoat

There loads of cavity filled houses now I obviously don’t want this happening again

Nothing to do with insulation

Cheers for reply
This job was 3 sides the front and back there isn’t a problem . The rep put it down to cavity fill and said the front n back were fine cos of the windows and doors for moisture to escape. He also said that rendering cavity filled properties will fail. I hope it is just primer too soon because that’s an easy sort.

Someone had fassa basecoat delam (with top) on here before

It don't like moisture, seems like it turns to mush and I think it blew.

Search the threads.
