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.
They don't usually go away. You'll need another coat of paint and be sure to use even pressure and feather in those roller marks.
The only way to rid would be to sand the roller marks out using a p120 grade sandpaper or finer then applying the paint properly using a roller and levelling / flattening off the paint properly when applied.
A second coat of paint can help cover roller marks, especially if the first coat was applied unevenly or if the paint is thick enough to fill in imperfections. Here are some tips to ensure better coverage:
What Are Roller Marks, Brush Marks and Paint Stippling? This happens when the paint coating fails to dry to a smooth film. You might be seeing unsightly brush and roller marks, or other unintentional textured patterns left in the paint by the roller.
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.
The second (or third) coat of paint on the “oops” areas will even out marks and leave you with a flat, even finish.
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.
Fine Grit Sandpaper (120-150 grit): Essential for smoothing out any roller marks or uneven edges before applying the next coat of paint. Sand lightly to avoid damaging the wall surface.
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.
Another question we get asked a lot from DIY painters and other contractors is, “how many coats of paint do I need when painting the interior or exterior of a home. The general rule is that you should use two coats of paint.
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.
DIY beginners sometimes assume that one coat of wall paint will do – and end up with patchy or thin paintwork. Usually, you'll have to apply at least two coats of paint to achieve a smooth, even finish. Applying multiple coats also helps build up the paint so it's more durable, and less prone to chipping.
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.
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.
Floetrol helps these water based paints perform more like oil based paints which ultimately makes using the paints easier as latex paints can tend to be heavier making them less forgiving when being sprayed as well as having a greater likelihood of leaving a brush or roller mark behind when being applied by a brush or ...
Wait Times Between Paint Coats
Oil-Based Paint - When using oil-based paint, you should wait at least 24 hours before adding a second coat of paint. Water-Based Latex Paint - When using water-based latex paint, you should wait at least 4 hours before adding another coat of paint.
The first is that the roller was not loaded enough with paint. When this happens, the roller drags across the surface, leaving streaks behind. Another reason for roller marks is when the paint is too thick.
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.
There are several ways to determine whether a surface is dry: OIL BASED products are dry if they are no longer tacky and do not emit a smell. WATER BASED products are dry if they no longer feel cool to the touch and a powder will form with light sanding.
Dip your roller lightly into the paint. It should cover less than half of the roller. Roll it back and forth on the ramp to distribute it evenly; this is how to stop patchy paint when using a roller.
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.
