    Hi AECB forum

    I have a question regarding the use of plaster as the airtight internal layer in a retrofit: does the plaster topcoat have to be polished for it to be considered airtight?

    Thanks for your help

    A polished finish as you describe it may offer some small improvements, but what I've read in research papers you'll get 99% of the way there simply using unfinished wet plaster.

    Great! That'll save a bit of time. Thank you very much for the information.
