I am painting a wall and need help!?

I'm painting on somesort of wood, that kinda feels like wallpaper... It's browny black and I am painting it white. Anyways, I've done an undercoat, two layers of white. I plan to paint the wall white aswell... However, most of the wall looks white but there are large gray areas that I can't seem to get rid of. My question is, if I paint the white glossy wall paint on the wall, are the gray spots that are visable on the undercoat going to show up on the overall result?


Also how do I achieve a final result that is streakless with a roller? Also any other painting tips will be appreciated!I am painting a wall and need help!?
Purchase some Kilz and paint all the ugly spots. We used Kilz on a den one time that had dark paneling and the finish coat was beige. The dark never bled through in 10 years. We are big believers in Kilz. You can find it almost anywhere that sells paint.





Also, when you use a roller, roll on a large X shape and then go over the X making a large square. Then move on to the next spot. I've never had streaking problems doing it that way.I am painting a wall and need help!?
You definitely need a stain blocking primer such as Kilz. The gray spots will eventually show through without it. Using a roller to get streakless walls is not difficult.





Make sure you have the roller soaked with paint, no dry spots. Now hold the roller and paint an X on the wall. Angle the roller to the left and to the right filling in the X until it makes a large square. This allows you to go over the area several times and ensures that each ';area'; is covered evenly. Make sure not to press really hard on the roller to get every last drop of paint. If you are you need to reload with paint. Pressing hard will leave you with streaks from the sides of the roller.
Try Kilz, but use the alcohol based product. It should seal the bleeds. We have also used varnish to seal knots and then painted over. Remember that a gloss finish will show imperfections moreso than flat; but on a wood wall it might look neat. To avoid streaks, begin in an x pattern, then roll right/left with a full roller of paint. Then roll up/down to ';run'; the paint out of the roller and lay it out. Keep a wet edge as you move down the wall.
because I can't see it, have to guess the guranteed way. Get some Kilz. It is an undercoat/sealer that should stop any ';bleed'; thru of anything(this sounds like mold). Give it a coat over the gray. Let dry. Streakless with the roller is how you use the roller....don't leave streaks. Can't explain it any better than that.
Only one thing to add to all of that. You let each coat dry completely before the next, right? Almost dry paint will pull, or peel away, leaving it splotched or streaked. You can't go wrong with Killz.
Try using a stain blocking primer on those areas, more than likely will continue to bleed through if you don't seal it.
