    Hi,

    I've bought some insulated plasterboard and hung some of it with mushrooms, the plastic things to go through the plasterboard into the masonary behind them. When I put one in, there's a fair thickness sticking out the other side, like about 3mm. Are you intended to skim over the whole sheet covering over them, or should you bash them right into the board so they are flush with the board?

    thanks,
    J

    Bash them in!

    Are you gonna skim the boards or tape-and-joint them?

    Mushrooms are ok if your skimming over them, but for taping your better off sticking them to the wall with bonding compound.

    Good luck:)

    Not too well. I'm thinking I didn't drill deep enough holes... There still protruding by about 2 mm. Is there any chance of skimming over that amount?

    when using the mushroom method - if the wall is not entirely flat -you will hammer the pb along this wall and it will look off.

    best bet is to use the plasterdoard adhesive.
    as said get a mixing agitator and use about 1/2 bag.
    put about 20 dollops from a gauging trowel onto wall - for the 8 *4 sheet
    place pb against wall - lift to the ceiling and push the board in.
    a few pieces of spare pb will hold it in against the ceiling
    with a large straingth piece of timber make sure the board is level with the others both vertically and horizontally.

    no need to use the mushroom pegs at all.
    and you can use insulated pb on the external walls.

    if this is your first time - get someone to help
    have a look at some images of lads pb-ing a room - search the web

    let us know how you get on.
