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.
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.
To ensure you have the right amount of paint in your regular brush, you want your brush to be damp, but not soaked with water before you put it in the paint. Once you put paint on the brush you need to unload the brush on a damp paper towel or piece of paper, so you can control the paint and it doesn't flood the model.

The brush is wet with paint meaning it will go really far and give the best coverage. When wet brush painting, you can often paint a piece of furniture in a single coat. Dry brushing paint will not give great coverage. But that's the intention!
Patchy paint can result if paint has been applied unevenly. Patchy paint can be down to a variation in surface absorption. Walls might appear patchy if they have variation in texture. Using paint that is not fully mixed can cause a patchy appearance.
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.
Walls, Wood, and Metal - Small 1/4″ roller covers or foam rollers will produce the smoothest finish. Light to Medium Textured Surfaces - Microfiber rollers are best. Smooth Surfaces - Use a white woven short nap roller for an ultra fine finish.
Sand down the foam with a sanding sheet and slice off any additional pieces using a craft knife to achieve a smooth working surface. It is far easier to better prepare your material, rather than trying to correct it after painting! Next, seal your foam using an easy to make mix.
If there is a very noticeable amount of air bubbles during application, try slowing down application speed. Follow label and data page directions for the appropriate applicator. Determine the correct roller cover type or nap based on the coating being applied and the surface to be coated.
Never roll over bony prominences – bones can be mistaken for adhesions but repeated rolling could result in inflammation of the periosteum. Avoid rolling over joints – rolling joints can cause inflammation of the tendons and ligaments around the articulation. Also, avoid hyperextension of unsupported joints.
De-fuzzing paint roller heads.
A new paint roller can sometimes leave behind fuzz, particularly if it's not a high-quality roller. Simply wrap some painter's tape around your fingers with the sticky side facing out, then run the tape over the roller before painting to remove the fuzz.
You want to use even, consistent pressure when painting. Remember, pressing too hard will leave behind roller-edge streaks. Not pressing hard enough will lead to inconsistent paint coverage. Practice on a loose piece of drywall to get the feel down before painting your wall.
Painting over existing layers of paint is usually the easiest option. A paint that has high coverage and a thick texture, such as our Claypaint or Lifestyle emulsions, will even out any hairline cracks and slightly bumpy surfaces. Both products can go over a multitude of wall substrates.
Consequences: Applying a second coat too soon can lead to peeling, streaking, and uneven colour distribution. Solution: Always follow the recommended recoat times and test a small area if you're unsure.
When paint is wet, it tends to appear darker due to less light reflection. But as it dries, the water evaporates, causing the paint's hues to lighten up. Oil, acrylic, and latex paints are exceptions to this, appearing darker as they dry.
Painters often use traditional rollers for uneven exterior walls and foam rollers for smooth interior walls, doors, and cabinets. Foam rollers glide along a smooth flat surface very easily and dispense the paint on the surfaces evenly. Foam rollers tend to last a shorter period of time than traditional rollers.
The perfect amount of paint to load on your roller should be just shy of overflowing – you should be able to see a very small amount of the microfibres and the roller should feel slightly heavy. If you're unsure, it's always better to start with less and add more as you go along than trying to remove excess paint.
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.
Before painting
Prep your roller by washing it out thoroughly under the tap, which should also remove any excess lint. With your brush, soak it in an inch of water for 10 minutes. Ensure you shake out excess moisture from both your brush and roller as you don't want any drip marks on your surface.
When you are using a water base paint, it's essential that your brush remains damp by dipping it in water. In the case of oil base paints, you can dampen it with turpentine. This allows the brush to flow smoothly across the surface. It enables the bristles to stay soft and flexible.
Acrylic paint, when left to dry overnight, can turn your brushes into hard, frayed, unusable tools. However, don't despair! There are effective techniques to potentially rescue your ruined paintbrush and restore it to a usable state.
