    Just wondered what you guys do on newly plastered walls that require wallpaper, got a newly plastered room to do soon and they would like 2 walls papered, would you just mist coat the whole room or leave the 2 papered walls and size them .

    I would have mist coated years ago when subbing. But when you turn up on jobs now to strip walls and see the mess using an emulsion creates I'd never go that route again.
    Size all the way for me.

    Beeline primer / sealer for papered walls also the Anaglypta primer is ok.

    I now tend to use Optiva Primer for new plaster under emulsion

    Just echoing Simons info. I used to converse with Beelines chief chemist, Ian Pw, who told me the 7 active components of Beeline primer sealer and why he ranked it first in your situation. He has Zin Gardz next

    I no longer wallpaper, but I would size the walls.

    I’ve seen people mistcoat the walls and when they papered, the paint would come alive and come through the joints.

    I read somewhere that diluted PVA is good before wallpapering on the bare plaster???

    Mistcoat with contract before papering will only end in disaster, beeline primer/sealer 1st, gard 2nd then a couple of thinned paste coats maybe with a drop of pva mixed in 3rd but not for anything else than a blown vinyls. Joints may split etc

    Used beeline for first time this week. Review to come. Bet you can't wait. Spoiler it's white gardz and will work.
    Tinted acrylic primer so joins don't show gets my vote if you are papering. Get from jhonos. Done many times myself.
    Oh. No bus so walking home nissed a tad. It's cold and foggy. Cars are frozen so watch out with paints.
    I'll add
    Contact emulsion is some stuff. Disliking it more every day.

    Been using both Beeline wall sealer and Gardz for years, both great products but they are different products with different abilities.
    Beeline sealer is most definitely NOT white gardz @Wayners.

    I did a long post in the wallpaper section about the the issues that can arise when using gardz to seal (overseal) walls with heavyweight papers that have long soak times. This has been confirmed by Anaglypta and Lincrusta.

    As for the original post I'm 100% in the seal not mistcoat camp!

    Interesting. I used the beeline this week and soon as I popped lid I thought this is pva. Smells like pva. Rolled on old pink plaster and gave a translucent but a little white in colour coat. Had a sheen like silk paint. Sealed well though like Gardz and gives what appeared to be a hard shiny surface. It's not sticky like pva when drying, and I've only used the beeline once, so need to keep with it and see how it performs, and get s better understanding of it.

    @Buckers post is at the bottom of here.. I think it's the one mentioned about Gardz Vs Beeline

    Here is the beeline primer sealer.

    Sensible money too
    Mix 3 - 1 for plaster. So goes a long way

    Omg.. Watch this...:whistle:
    Not the sealer but who cares.

    Anyone used beeline to seal contract emulsion with a view to paint over. Bit unclear reading data and just phoned their technical department and it shuts at 4.30....

    So beeline can be used as wallpaper and emulsion primer?

    Needs water adding though as instructions say.

    Plan B is acrylic primer as this contract stuff on job is naff. Real dry.

    I phoned beeline. Yes you can use to seal contract emulsion. Need to dilute as per instructions. Going to try once wall.
