How do I prevent brush stroke?

Question by unknown: How do I prevent brush stroke?
I have a Purdy Nylox Sprig.
Please do Not tell me go and buy those sponges, those are crap.
I have applied the paint with one stroke, back-brush it once, but still brush stroke, but less.

Iam painting the door trim and flat.
IS behr paint the problem? or the painter?

The problem is Behr paint it’s too thick, you will need to thin it a little, there is a product called Floetrol for thinning latex paint and it makes the paint flow out nicely eliminating brush strokes. Of course you can also use a little water to thin it as well.

    For you to produce a good result, you use sprayer. Or just do the second coating with your paint brush since you already worked on it.

    This can be a few reasons: first, the paint may be too thin, not mixed up enought, or just junk paint.
    second, its the wrong brush. I assume youre using latex paint – and I like Purdy, its my favorite brush, but I’m not sure of the (Nylox Sprig). I just get Purdy angled brushes that say “for all paints” on it, oil or latex. The brush should be whitish, not black bristles.

    Finally, it could be the finish of your trim, and the “flat” your using now. Usually, doors and trim are painted with “semi-gloss” paint, and these look nice, but are hard to paint over sometimes, especially if your changing the finish to flat, and/or changing the color makes it even worse. Semi-gloss paints go on a little thicker than flat paints.

    One more thing, I noticed you said you’re applying paint with 1 stroke, then back-brush it once? This is not really how most people paint. You have to get that brush wet and paint small sections with many forward and back motions till it covers, sometimes going back over your work, re-dipping paint, etc.

    When I paint a door I paint the grooves with a brush, then I go over that and the rest of it with a roller (the smallest) I never get brush strokes. I think that a quality paint helps. I agree with you about the sponges

    nah, your brush is fine.

    Brush strokes come from:
    1) bristles too stiff (not yours)
    2) material (paint) that doesnt self-level enough (likely)
    3) lack of delicate application. (sounds like your doing this somewhat)

    Behr is kinda gluey and doesnt perform all that well in my opinion.
    You gatta just baby your finish stroke- if not dong it already, float your last stroke back into the area youve already painted and gently lift at the end gradually. You might not b doing it quite enough but there are these factors too:

    a) flats performance isnt as self-leveling as a higher sheen.
    b) There are other paints (mainly satin and semi’s) that have better leveling properties, cost a little more, and are sold in reg’ paint stores.

    i fit matters to you, you might wanna pick up a gallon of different material – dont know what stores you have near you but if you just call or walk in and describe that youre doing trim etc etc, they can give you a winner. (eg Sherwin Wiliiams “pro classic”, ICI “aqua sash” (semi) – those two are great self levelers.
