Plaster around Stove Flue

    Hi all,

    I got a wood burning stove installed a while back. The flue exits the top and goes into the chimney at an angle. I need to plaster around where the flue enters the chimney (about 6" all round the flue) The guy who installed it back fillled the cavity with cement. Any recommendations on plastering it? There's roughly 1/2" or so to be filled. Should I use a particular type plaster for the heat?
    Hope I described it ok.

    Hi,

    I presume you mean it was filled with fire cement and you just want to apply the finish ?

    1/2" depth is a bit of a nuisance, you could fill it out more with bonding, almost level with the existing finish and then apply a finish of skimcoat.

    I think if you try filling out that depth with skimcoat or patching plaster it will just crack and maybe even fall off.

    Wait for a day you are not going to use the stove, if the plaster is heated up suddenly it will definitely crack, while the plaster looks set it is not cured so introduce the heat slowly.

    Make sure the existing filling has not cracked, if it has you will probably need fire cement around the flue.

    Yes, fire cement is what I meant to say.
