Before you start a paint job, you actually want to wet the paint roller cover with water. “This primes the roller cover to soak up as much paint as possible,” Barr explains. But don't go too crazy—Barr suggests removing excess moisture with a paper towel and a good shake of the roller so it's just slightly damp.
Comments Section New painters tend to make a couple of common mistakes. Pressing the roller too hard, and not waiting for things to dry enough before doing the next coat. When I say pressing too hard, I mean press too hard on rollers, trying to squeeze out every last bit of paint before they reload the roller.
Paint in Small Sections
If you have a large wall, break it up into small sections that are manageable. It'll make painting with a paint roller easier and your results will improve. Make sure each section is two to three square feet big. The roller should sound wet at all times when you're painting.
Method to prevent roller marks
One is to make sure the paint is mixed well before using it. Another is to use a high-quality roller cover and make sure it's in good condition. When rolling the paint on, start at the top and work your way down. Apply even pressure and avoid going over the same area multiple times.
Use enough pressure on the surface to ensure control of your painted line, but don't press hard. The bristles should flex slightly as you paint. TIP: Work in strokes twelve inches or longer.
Try to maintain a wet edge. When using a roller keep the open side towards the area just painted. Try to complete one full surface at a time. Paint in an even grid pattern from top to bottom.
There are various reasons why your paint roller slides instead of rolls. Usually, it's because you either didn't attach the cover to the roller frame correctly, you're applying too much pressure to the rollers, or there might be too much paint on the roller.
More often than not, roller marks occur when you fail to load your roller with enough paint, or have exhausted the paint in your roller and are trying to cover more area than you should. Finally, applying the wrong amount of pressure can cause paint to push out around the edge of the roller, creating a streak.
POSSIBLE CAUSE
Applying the coating (e.g., primer or paint) too fast. Using a roller cover with the wrong nap for the product. Overloading the roller cover with paint. Overworking the paint once it is applied to a substrate (e.g., the surface to be painted).
Dabbing painters tape against the roller cover is an easy way to work free any extra fibers. Once your the cover is lint free you're ready to begin painting.

When you're waiting to apply your second coat, leaving paint on your brush or roller can cause them to dry out and become unusable. Save time washing them out – instead, wrap up your tools in aluminium foil between coats. This will keep the paint on your brush and roller fresh for a long period of time.
Also, a second coat of paint helps remove roller marks by allowing you to feather out some of the unevenness in the finish. You can do this by overlapping the uneven areas to create a more uniform finish. However, you need to apply the paints with the proper technique for this to work.
Roller marks are exactly what they sound like — evidence of where the painter used the roller brush. They are often caused by a painter putting a second coat of paint on the wall before the first coat has completely dried.
Many painters “break in” a roller cover by priming it with water or thinner. In our lab we never prewet a cover before painting. If you choose to, you must spin it out with five or six strong pumps so it is only lightly damp. Then take even more moisture out by blotting the cover with a paper towel.
Weathered Surfaces: If the existing paint is weathered, faded, or peeling, applying two coats is generally recommended to ensure proper coverage, adhesion, and protection against moisture and UV damage.
Always cut in first then continue painting with a roller. Cut in and paint with a roller one wall at a time. If you cut in all areas first and then roll the entire room, the paint that was applied when cutting in will have dried quicker and you will be left with a patchy, uneven finish.
Be careful not to apply the wrong type of pressure or fail to use enough paint on the roller, which may have created the streaks in the first place. Use fine grit sandpaper to even out roller marks. Wipe the surface down after you've finished with the sandpaper. Then paint over the streaks lightly.
Roll a “W” on the wall with the roller, filling the empty spaces in a top to bottom motion. This will help place an even distribution of paint onto the wall. Repeat this until you have completely covered the entire wall.
There are a few ways to fix paint brush strokes. You can use a thinner to make the paint flow more smoothly. Use a liner brush and clean up the edges of your stroke. Also, you can use a dry brush or another type of brush with a smaller tip to blend in your strokes.
