    Where I painted mist coat with brushes, wall has thick streak of paint. I had to sand it down atgain before top coat.

    Would roller brush get rid of this problem? Or am I doing something wrong?

    Roller would help, streaks are likely due to poor quality brush.

    It is Hamilton make, and looks quite decent quality, but will try roller.

    Mist coat too thick, make sure it's a matt emulsion,ratio of water to paint, depends on the quailty of the paint, a better roller, alway better to have a couple of mist coats,rather than one thick coat.

    You will find first mist coat usually shows up any imperfections, so fill, rub down & on with a second mist coat.

    And always throughly wash a new roller before use.

    Isn't a second mist coat a bit of a misnomer? I mean, a mist coat seals the wall/plaster. A second mist coat does nothing towards sealing a bare wall, because the wall isn't bare anymore.

    Will be bare in places, if you rubbed down filler.

    yup filler calls for more mist coats.

    What I'm saying is a weak mix on top of an already sealed and dry finish is likely to leave a chalky/not very well adhered finish.

    Why are you painting wall with a brush anyway ?

    Doesn’t everyone use a roller nowadays ?

    Yeah sure, cut in with a brush (obviously), then immediately go over cutting in with 4”roller and same paint, ie mistcoat / topcoat, getting as close to edge as you can

    Wether you paint with a brush or a roller, the two methods will leave a differant texture

    Nothing worse than seeing wide band of brush marks around light switches, architraves, ceiling roses, etc, then a roller finish to rest of wall

    Winds me up, not even my own house, can’t stand it :mad:

    Watched a bloke painting the exterior walls with a house broom some while ago, looked ok apart from the large amount of masonry paint all over the concrete path.

    yup roller works great.
    The edges and corners still need brushes.

    cheers
