Mistake: Paint drips, runs and streaks Why it happens: An excessive amount of paint on your roller or paintbrush can cause paint to drip and run. Streaks, where paint is unevenly distributed on a wall, typically result from having too little paint on your roller or brush.
Applying paint in even, uniform strokes is essential for a streak-free finish. Start from the top and work your way down, maintaining a 'wet edge'—this means each stroke slightly overlaps the previous one before the paint dries. This technique helps to avoid marks and ensures a seamless blend between strokes.
Tips for Avoiding Streaks: - Use a wet palette to keep your paint moist and workable. - Work in thin layers, allowing each layer to dry before applying the next. - Avoid overworking the paint, as this can lead to lifting and streaking. - Keep your brush loaded with paint but not overly saturated.
Primarily, the paint may not have dried properly. If it is still wet when the light hits it, it will cause a reflection that looks like a texture or grain. Secondly, the paint may have been applied too thickly, which will also create a texture or grain.
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.
If they are due to improper painting techniques or using low-quality tools, they may not go away completely even after the paint dries. However, if the streaks are caused by a lack of thorough drying between coats or high humidity levels, they may disappear once the paint has fully dried.
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.
Use of the wrong type or size of brush. Applying too thin of a paint film. Painting a hot surface or in direct sunlight. Coating a very porous surface.
White China—These natural bristle brushes are best used with oil-based paints, especially enamels and varnishes. Ideal for woodwork, enamels, or marine applications, White China bristles virtually eliminate brush marks.
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.
Clean and Prime: Always start with a clean surface. Dust, dirt, or oils can prevent paint from adhering correctly, leading to uneven paint streaks. Apply a quality primer to create a smooth, uniform surface that paint can adhere to effectively.
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.
Roller marks are caused by the paint roller leaving behind streaks of paint on the wall. This can be due to several factors, such as using the wrong type of roller for the surface you're painting, using too much paint or rolling in one direction instead of back and forth.
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.
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.
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.

Tip #1: Extra coat of paint
Try another coat of paint. Just go over the areas where you see streaks and even them out with another coat, being careful this time not to apply the wrong type of pressure or fail to use enough paint on the roller, which is what created the streaks in the first place.
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.
Old paint might have debris or clumps (even if it's an unopened can!) and new paint might need to be stirred.
For consistent control and smooth finish, we recommend microfiber roller covers. 1/4″ – Use for ultra-smooth surfaces like cabinets, doors & metal. 3/8″ – Use for smooth surfaces like walls & ceilings. 1/2″ – Use for semi-smooth surfaces like textured walls, textured ceilings, plaster & wood.
Use this Flood Floetrol 1 qt. Clear Latex Paint Additive to improve the performance of latex and acrylic paints and reduce the appearance of brush marks. It allows latex paints to be sprayed with less pressure to help reduce tip clogging and piston freeze-ups.
