We started painting my sons' room. We picked out an awesome color, "Chinese Dragon". We picked a flat to help hide flaws in the wall. The walls were a pale yellow semi-gloss and we didn't think it would require primer, however after testing a small area, the paint was not going on well so we decided to prime the walls first. The guy at home depot recommended using Ralph Lauren deep tone base and tinted it very close to the color we had selected. Well, the primer streaked really bad, dark and light places all over. We didn't think it would make much difference. We have painted one wall, we also added something to the paint called "paint-tex". It's like a sand substance to add texture to the paint, also to hide flaws. The color is also streaking very badly. You can see light and dark places all over the wall. We haven't tried a second coat yet. Do you think this will solve the problem? If not what can we do, it doesn't look like color blending, it just looks bad.

Before we bought our house, wallpaper was removed from the drywall in our bathroom and then the walls were painted without removing the adhesive. Short of tearing out the walls and replacing them, is there anything else that we can do? Can we "mud" over the existing paint to smooth the walls and then paint over that? Or, can we use the type of wallpaper that is used over paneling and is paintable? If this is possible, do we have to do anything more than the normal preparation required for wallpaper?
