we're usuing a very light colors, the best roller and yet when the paint is dry and we look at it from an angle it looks streaked and awful in places!

the paint looks good straight one, it's just when the light hits that one angle it's awful! we've put on more then one coat, let it dry long enough btw coats, the paint underneath was compatable...so i don't know what's wrong?

does this usually happen and i haven't noticed before or is there something really wrong with this paint job?

    Did you degloss the prvios coat with TSP?
    Was it a no rinse TSP like Jasco?

    If you did not prewash the wall or you used standard TSP without completely rinsing then streaking can be a problem..

    The other possible issue is cheap paint. Low end stuff has a lot of clay and is what is known as a dry coverage paint. It looks spotty then drys to coverage. They are designed to be sprayed. When rolled they look bad.

    Just some possibilities

      I was sort of thinking the same thing JSin.

      Did you wash down the walls first? They need to be clean of anything for the paint to stick properly.

        (Off topic) I HATE the prep part of painting. I think that there is a real market for a service where a person or persons could wash walls for people who hate doing it. (back on topic)

        Good hell, my friend, that sounds frustrating. Especially since you are midwinter and therefore cannot open all the damn windows to let the fumes out. I wish you luck.

    yes i agree that more info is needed.

    are the streaks looking like the lines of each roller pass?
    i've had that happen and it can be that the paint is drying too fast as you are applying it and you are getting lap marks, which it seems to me only happens with 100% acrylic paints. they're high end, but they do have this problem. this has been a point of contention for me and i don't know the solution. i don't even know for sure if it's drying too fast or if it just comes with using 100% acrylics.

      some thing else occured to me.... What kind of cage you useing for the roller?

      The cheap 1.99 cages tend to drag a bit. It is worth investing in a ball bearing type. They run a little less then 10.00

        wow you guys, i feel like such an amateur! lol! all this awesome advice! :-)

        i think, like reid (?) said, it was drying too fast, and i was not using enough paint cause i was running out and trying to make it go a little longer...this backfired and i actually had to get more paint to do over!
        so after it dried, i gave it a 3rd coat and it looks spotless...the trick is to press with equal pressure, use one of those self filling rollers (with paint it in) and let it dry...it will look very sreaky as it dries..but when fully dried it looks uniform. i've read this somwhere online...also a tip, do not go over spots unless you wanna redo the whole wall...hold off even if you feel very tempted - chances are it will dry well...and it did.

        i was painting with flat (on flat)...as i hear this is the hardest to paint - now i know why! eggshell or satin next time for sure!

        thanks again for the tips everyone! back to the fumes..................
