I am looking to skim a lightly textured ceiling (probably rollered artex) that has several coats of emulsion.
Looking through other threads it seems the process is to pva, use a bonding coat then the skim. I'm assuming the emulsion is already providing a suction barrier so would I need one or two coats of pva?
Secondly, the old gap tapes need to come down which I replace with fibreglass tape. I assume I pva before putting the new tape on? Are there any other precautions to take to prepare the different surfaces?
