Suitable Weather for Plastering

[MortarThePoint]

I'm going with wet plaster to (Stranlite/Fibolite) blockwork and skim on plasterboard partitions. I was wondering when it would be OK to have this done. I'm still going through first fix, slowed by every full plasterboard needing the wife's help as well of shear weight of activities.

 

My layman's understanding: I had hoped to have it plastered in September when the weather should be mild enough to not dry the walls too quickly but dry enough to be able to use fans to blow air though and avoid the fabric of the building getting too wet. That's slipped away and the plasterer says he's available end of Oct / early Nov.

 

Below is some weather data from last year. I guess the most important things are temperature and humidity/dewpoint.

We work everyday As long as the inside temperature doesn’t drop below +2 

Even exterior render we work down to + 2 and cover for heavy frost 

 

Recently we were wet plastering in 32c Add plenty of Crème of tar tar

Thanks nod, is there no bother when it's humid getting all the water out or any ill effects on the rest of the building (timber joists, studs, doors etc)?

If you are able To run a fan to keep the air circulating That will help 

Very few issues with modern plasters now

Roughly how much water goes into the plaster per m2 of blockwork wall?
