Got a job to start its 2 big ceilings in a resturant there bout 25ft squared each. Just wonder would it be best to stop bead it in middle ( to make it easier for me ) or get it all in the one lift. Problem is its a reskim and would need plenty of pva to prevent drying to quick because it so large an area.any ideas? Suppose i could try and get someone to give me a hand , Is there anyway of slowing the setting times on the skim? Sorry for all the questions but not not sure, wat the best way to tackle this job is ! :-/
