If your roller runs dry, you'll find yourself with uneven patches, leaving your walls looking inconsistent. Also resist the urge to rework wet paint and trust the process… it will look patchy whilst drying! Another common culprit in achieving a patchy effect is not maintaining a wet edge whist cutting in.
To troubleshoot, try ensuring consistent drying times between coats and experimenting with different application tools to see if that makes a difference. If you've tried rectifying the issue with no success, it might be worth considering starting fresh with a higher-quality paint.
Having paint streak is very common when not applying enough material, or using tools that don't hold enough material to disperse it properly. You want to make sure the roller has a uniform amount of paint on it while rolling, if it starts ``screaming'' at you on the wall, there's not enough paint left on the roller.
The larger patches show through because of differences in the texture of the surrounding wall, which has had several coats of paint applied over the years. So you have roller texture and smooth drywall patches.

First, roller marks are a common culprit. These can occur when the paint roller isn't fully immersed in the paint or is applied unevenly, leaving a patchy, streaky appearance once the paint has dried. Second, brush marks are another common cause of streaks.
Brush marks are caused by strokes that leave the paint with a rough texture and visible brush strokes. The rough texture and visible brush strokes can be easily covered in a second coat of paint by using a slightly different technique than you used for your first coat.
Unfortunately, roller marks will probably not go away when the paint dries out. However, as the paint dries some of the roller marks will become slightly less noticeable. But simply waiting until the paint has dried won't solve the problem completely.
Try to keep a wet edge and finish one wall at a time. Apply light and even pressure on your roller. Don't worry if the wall looks patchy at first – this is normal for claypaint. Wait a few hours and you will notice that the colour evens out as it dries (dark colours take much longer to settle to their final colour).
Wall condition: If your walls are in good condition, you may only need one or two coats of paint to achieve a smooth, even finish. However, if your walls are rough or damaged, you may need to apply additional coats to cover up imperfections.
How to fix uneven or blotchy paint: No matter how many additional coats of paint you add, this problem likely requires going back to the drawing board. If you run into uneven or blotchy paint, the best thing to do is start over.
Not Fully Loading the Roller
The roller needs to be fully loaded with paint to the core, otherwise you'll get air bubbles on your wall, resulting in “paint acne.” To avoid this mistake, roll back and forth on the roller tray until all bubbles are gone and the roller feels heavy.
Lightly sand the troublesome area with 150-grit sandpaper, then tack the walls. That's painter lingo for “Wipe it with a cloth to get rid of dust.” (Easier than the lingo makes it sound!) Then re-paint the area, maintaining a wet edge—meaning, don't let the paint dry until you finish the wall.
There's rarely an issue with waiting too long between coats of standard house paint. While it's typical to recoat within 4-12 hours, some projects allow weeks or even months between coats without any problems. For instance, on larger builds, painters often wait until other trades finish before applying the final coat.
What happens if you apply a second coat of paint too soon? Applying the second coat of paint before letting it dry will result in peeling, clumping, and bubbling that can be time-consuming and expensive to repair. It can also result in an uneven colour, ruining its appearance.
Paint ghosting happens when dust, soot, or other airborne particles cling to walls and ceilings, forming subtle, shadowy patterns. These patterns often show up on cooler surfaces where moisture tends to settle, creating ideal conditions for particles to stick.
Ghosting happens when mildly damp, warm, and possibly sooty interior air condenses on the sections of walls and ceiling that are colder because part of the wood frame is uninsulated. This results in black sooty stains on your walls and ceilings that follow the patterns of your home's framing.
Using a high-quality primer provides many benefits, including hiding imperfections and promoting adhesion. The KILZ Adhesion High-Bonding Interior/Exterior Latex Primer is perfect for surfaces that are difficult to paint, such as glossy surfaces, vinyl, and plastic.
For bulges caused by loose screws, tighten them with a screwdriver until they are snug and flush against the drywall. Take great care not to over-tighten, as this can damage the drywall or create new bulges. Regularly checking and tightening screws can prevent future bulging problems.
