    We have a 3 year old conservatory with a bare knotty pine ceiling.

    Can anybody give advise on what to coat it with and how best to apply it?

    I was thinking of a water based varnish!

    I thank you for taking the time to read this and for any replies.

    If it's a difficult ceilings that has many groves to get into you can spray the ceiling and it brings a good finish.

    As for what to use are you looking to change the colour varnish it or what ?

    If you are looking to paint it, When you come to purchasing the paint ask the guy about it suitable for spaying onto a ceiling as it may be to thick.

    Hi NB

    Sorry I could not get back sooner!

    Unfortunately ceiling does have a lot grooves, it is T&G.

    Spraying it is not an option, as it is beyond my abilities.

    I want to use a clear coating, it as now mellowed to the natural colour we want.

    Would it also need knotting and if so is it possible to obtain a clear knotting. As the only type I have seen is shellac, which dark brown.

    Varnish is likely to crack with the movement of the wood. Personally I would cover everything underneath & wipe Danish Oil onto the wood with a cloth. You can also use a water based stain before oiling. If you were to use an oil based stain the oil would dilute the stain which it wont if the stain is water based under the oil. I'd suggest doing it when you are able to leave the windows open as the oil has a smell although any coating is likely to smell as well.

    if you do use varnish use accrylic cos oil based varnish
    tends to give a yellow tint with age

    as the wood is well settled i don't think varnishing would
    be a problem although you should seal the back before
    you put it up not an option in this case
    [make sure you give it a good clean first]

    Hi Dewy, Hi Big all

    Thank you both for your replies.

    I think I will take the Acrylic Varnish route, as I do not want to change its colour, and it also appears to be the least messy option.

    But I am still left with the problem of knowing if it is possible to obtain a clear knotting.

    Also are there any problems of using knotting together with acrylic varnish

    Hi Big all

    Many thanks for the Info.

    I think meths is/was used as the solvent in knotting.

    there is no need for knotting if you are using acrylic based varnish.knots won,t bleed through acrylic based coatings and the resin in the knots will be dry and hard by now.
    hope this helps.
