For u guys that reckon sunlight cannot dry it out too quick then think again.
That uni failure i had that i blamed on sunlight,well.
1 month after i repaired it customer calls me,s**t i thought not again.
No he asked me to come back and do a window wall in next bedroom that is to front as well.
Looked at it,,,when i came to do it he said can you also fix that bit there i forgot to say to you.
It was a bit that was cracked ,well it was blown,and it came off identical to the room i done,,,,carbon copy,,,i have pictures.
This room was plastered 3 years ago using pva,multi not uni.
Not by me also.
So 2 rooms blow different plasterers,different system,different coloured paint in both rooms.
Only thing in common,,,,both are left hand side walls in a south facing bedrooms where sun tracked right down them.
Pictures will follow.
