    Dear All,

    Just have had the walls skimmed. I always use Dulux paint!

    Do I need to prime the walls with something or another?

    Many thanks

    Before others say this has been answered umptine times do a search?

    1. Leave walls until surface is dry, no wet pathces.Then

    2. Mist Coat, i.e 1 coat of watered down SuperMatt emulsion. Then

    3. 2x coats of Dulux Trade SuperMatt Emulsion

    This is specially formulated for new plastered walls

    Good Luck

    Always tend to use Dulux myself - However, have used this to good effect before now.

    Designed to be applied straight onto new plaster although it's still worth adding a splash of water to cope with the suction off the plaster when applying it.

    Finish with a couple of coats of your final colour and job done...

    The fact that you have just had the walls skimmed, means that it will be dry in a few days.

    Supamatt by Dulux is OK, but you might find it costly or the finish not that good compared to normal matts. Also the Leyland prodcut is also good - good advice from the other guys. I tend to use Albany (Brewers) white supacover on fresh plaster and it alsways gives a good finish about £15 for 10L

    If however you want yet more choice, due to skim and not a decent 2 coat plaster job, you can mist coat the walls with a non-vinyl emulsion watered down, and then top coat with what you want, be that soft sheen, Vinyl matt, silk (devils work) etc etc.

    Thanks for the reply guys.

    I was just about to buy the above mentioned items when my wifes 3 uncles apparently said that they have all re-done the homes and they put Unibond PVA on the walls first (watered down to 1 in 5) and then painted on top after it dryed!

    Does this actually work? Their homes looked good? Is this an option? Has anyone ever tried this!

    Reason I ask, is that he is insisted to come around and do it for me. Trying my best to get out of it.....

    there is no paint manufacturer that says you pva walls first. It causes so much trouble, mainly peeling of paint from walls.

    There are many places that say to pva, but i would go with the paint manufacturers myself.


    All say to mist coat the walls

    you want the paint to key into the wall. If you pva you create a barrier to adhesion. even worse, pva is designed for plastering, and its designed to re activate to a liquid form when wet.

    Not exactly what you want when applying paint

    Thanks Guys. Thats exactly what I was thinking.

    Just to confirm, all I need to do is apply a mist coat (which means watered down SuperMatt emulsion) and then just paint as per normal. Obviously two coats! Is this correct?

    Many thanks in advance.....

    yes, one mist coat, then as many coats as it takes to get a solid colour.......could be 3 coats (including the mist coat)

    my tip is always, read the instructions on the paint tin.

    Thanks Handyman.

    I know this is a stupid question! But the SuperMatt Emulsion is white I take it? And then the preferred colour on top? Or do you get the SuperMatt made into the colour you are painting the walls?

    Thanks once again!

    You don't have to use supermatt for the mistcoat. You can use the same paint as your top coat, but thinned.

    It is always better(in my opinion) to mist coat in white, it helps to produce the colour of your topcoat as it was intended.

    ie. one coat of white and 2 coats of blue will show the blue as it was meant to be.

    If your wall is dark to start with, 3 coats of blue might come out darker than it was intended.



    Mr. HandyAndy - really

    You can use the same paint as your top coat, but thinned. - steady HandyAndy this could be dangerous advice, what if the top coat is silk, eggshell or even just a vinyl base?

    A mist coat should always be a non-vinyl emulsion, just a cheap contract matt will do.

    Yeah, I guess I was generalising a bit. I know what I mean though :):):)

    Info from Dulux Trade Vinyl Matt:

    Ideal for use on woodchip, blown vinyl wallcoverings etc, as well as dry plaster and a range of building boards.

    To get the best results from Dulux Trade Vinyl Matt, make sure the surfaces to be painted are sound, clean and dry.

    Seal new or bare surfaces with a thinned first coat of Dulux Trade Vinyl Matt. (Up to 1 part clean water to 5 parts paint.) The normal finish process is 2 full coats of Dulux Trade Vinyl Matt on previously painted surfaces in good condition. Where similar colours are used 1 coat may be sufficient

    Think I will still stick to MIST coats with Non-Vinyl, after years of this practise I have never had any adhesion problems, but have seen many where Vinyl has been applied straight to surface without any priming.

    non vinyl for me on mist coats.
  19. "just a cheap contract matt will do."

    Absolutely, I use Glidden Contract Matt all the time as a base coat, dries quickly, primes filled areas, highlights imperfections etc.
