I am not professional painter .i have painted my room but a lot of stains and walls not even. how to fix it?

For the stains, use a shellac based primer such as Zinsser B-I-N or Kilz original. Then recoat with the finish paint. This should also help to even out the coverage of the paint.





Another question is what brand of paint did you use? Some ';bargain'; paints are low cost because they don't cover. Using a quality paint like Benjamin Moore may cost a little more up front, but it's worth $10 to me to not have to apply 2 coats (or more). Good luck.I am not professional painter .i have painted my room but a lot of stains and walls not even. how to fix it?
You can buy a paint/primer called Killz You can get it at any pain/hardware store.Purchase those $1.00 throw away brushes because you don't clean this stuff off. Paint it right on to the stains anywhere in the whole room,let it dry and use your regular paint,if you see that the stains are bleeding through hit it again.If the place your in has settled and it's thrown the building off so that your walls are uneven you would have to take the old material off and replace the studs and so-on that could get ugly.I found that using antique wht. helps hide alot of the waves in walls.I am not professional painter .i have painted my room but a lot of stains and walls not even. how to fix it?
Do a coat of Kilz then re-paint. If the walls are uneven you might want to do a paint ';wash'; which will give enough texture to keep from drawing attention to the imperfections of the walls. Paint wash is just painting with one color and then again with a slighter darker/ lighter color mixed with some glaze... use that to paint over the 1st coat doing large X's with the brush and then daubing with a soft cloth. Looks almost like a suede finish. Nice.
sand and use lightweight spackle to fix any uneven spots. as far as stains, buy a quart of interior KILZ to prime the walls. then repaint.
