Hi...I've posted something similar before but wanted advice on whether you think this will work.....

I recently dot and dabbed and skimmed a wall that had previously been skimmed. There was a double doorway in the wall previously as when you tap the wall you can hear part of it is solid and part is plasterboard. There were hairline cracks around where the original door opening was. Even after dot and dabbing plasterboard and then skimming it the hairline cracks have now appeared at the board joints which lead me to believe there must be a fair bit of movement in the wall.

I have only recently become aware of fibreglass mesh laid between 1st and 2nd coat. If i do this will this definitely stop any further hairline cracks?

Any help much appreciated

Maybe 9.5 your putting the dabbing on as thick as multi the hollow bit would sound much better

Unless you board the complete wall staggering the cracks with the boards, the casing is always gonna swell and crack
 
did you dab the boards in the same place as existing boards ??if so, you would get the joint on joint effect.....
No mate staggered the joints. There was only a double door sized part of the original wall that had been plasterboarded and then block wall around that. I plasterboarded so that my board joints didn`t match the existing ones and scrimmed as usual. I can`t believe the new board joints now have hairline cracks as the majority of it is stuck onto solid wall
