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?
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.
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
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.
