Sand over the drip with medium (100-grit) sandpaper on a sanding block in a circular motion until you can no longer feel the paint ridge or any surface unevenness. Switch to fine (220-grit) sandpaper and sand over the same area to remove any scratches from the previous step.
Reapply another coat to fill in bare spots. If there are clumps or bubbles on the painted surface, sand it, wipe clean, and reapply a coat of paint. To avoid streaks or lap marks from a roller, maintain a wet edge by applying paint toward the unpainted area and then back into the just painted area.
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.
A taunt string covered in paint or a straight edge dipped in paint is another way to lay in a straight line. A thin wheel like a pizza cutter could be used to get straight lines. You could make a paint drip and tip the painting letting gravity create the line. (Do this with thin paint on a smooth surface).
A paint edger is a professional painting tool that works well to paint straight lines, including 90-degree angles. Most paint edgers are square or rectangular, applying paint in cohesive blocks and lines.
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.
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.
Applying the second coat too early will result in lost time, money, and effort. Not only that but it'll also create additional stress that's not necessary. Applying the second coat too early will result in streaks, peeling paint, and uneven color.
To remove paint lines, lightly sand the edges to smooth them out, then apply a thin layer of paint over the area to blend the lines seamlessly into the rest of the wall.
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.
Oil based Paint Drying Time
After application, it will typically take 2-4 hours until the paint is dry to the touch. However, you'll have to wait a minimum of 24 hours until you can apply a second coat.
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.
Make sure the paint is completely dry. Once it has dried, take a smooth piece of sandpaper and sand* paint down slightly until the surface is smooth. Repaint the surface and maintain a wet edge on your roller at all times. Move slowly, and don't be afraid to use more paint.
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.
Uneven edges usually happen when painter's tape isn't used, or you paint too close to the edge of a surface. Messy lines are the worst. Avoid this by working in small sections and use a great tape to get a nice, even finish. If the damage is already done, simply go back over the edge.
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.
Ceilings and Drywall - Medium 3/8″ roller covers work best. 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.
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.
If you are installing both the walls and ceiling of a room it's always best to start with the ceiling to reduce the possibility of damage later on.
Smooth Out with a Roller: Gently go over the streaky area with a paint roller. Use light pressure and even strokes to blend the wet paint into the surrounding area seamlessly.
