Dabbing Insi Boards

Im assuming most people use the plastic hammer fixings as the mechanical fix when you dab insulation boards and my question is does the skimming crack where the plastic fixing is even if you scrim them??

The last time I skimmed boards like that they didn't crack and I've not been called back to sort it, but the builder put the fixing in so if it cracked it would of been his fault I guess ?

No need to scrim over arti ,just make sure the flat plastic head is sunk in to the face of the board a bit:RpS_thumbup:
