    Hi,

    Could anyone tell me how much water do you use to dilute paint for a mist coat for painting new plaster?

    Also, what is the best paint to use, vinal or matt?, also how many coats do you need?

    Many Thanks

    As a guide, around 10% water. A true matt will make the best mistcoat, and only one coat is needed followed by two top coats.

    jesus mate 10%? i would recommend 50/50 myself but i know the other guys on hear go for 70/30. 10% is much too thick

    also you always want to go for a matt on mist coating. take a look at supermatt, ideal for this

    I said 10% not knowing what paint he was applying. True some emulsions will work well at 70% 30% But for some that mix may be a little to much. Bye the way welcome back.

    Potty.

    If using Dulux Supermatt - 3 parts paint to 1 part water. If you're plaster is fully dry, you can use a trade vinyl matt or a trade vinyl silk to mist coat.
    Not Dulux rich matt.

    Do as potty says you wont go wrong.
    But what ever you do dont use a vinyl silk for miss coating.
    Go to crown decorating centre and get covermatt just thin it about 20% water.
    cheers mate polly

    I repeat:
    As long as your plaster is fully dry, you can use a good trade vinyl silk if you should desire.

    Guttercat your right just googled it and you can use a vinyl silk for mist coating i always thought because of the vinyl in it it wouldnt take to the plaster.
    I prefer a contract matt myself but everyone to there own.
    I am sorry i was wrong you learn something new every day.
    cheers mate polly

    Don't believe <u>everything</u> you hear or read on the internet.

    Some of it comes from people with less knowledge than yourself.

    Yes, and note the binding agent in macPherson's:

    A glorified PVA.


    We all know about that stuff! :)

    Handyandy, Guttercat was correct to give that advice. The coatings he mentioned will act well as a mistcoat, however, I am sure that he will agree that a matt emulsion is the more obvious choice. It is good sometimes for someone to suggest a different product, that based on his own experience he knows will work. No offence intended.

    Potty.

    The evidence speaks for itself. It is not MY words being used. Traditional thoughts are that a PVA based mist coat is a no-no.

    Handy. I take and understand your point. I cast my mind back to nearly 40 years ago, when I worked as a young dec employed by a local health authority. The paints in those days were Permoglaze & Macphersons, they for obvious reasons were of vinyl content. We many times used these as a mistcoat with good result, dont condem a product than can and produce the desired effect.

    Potty.
