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.
Use extra paint on a flawed area, to fill it in or obscure it. Apply two coats of your texture paint.
How to fix uneven or blotchy paint: No matter how many additional coats of paint you add, this problem likely requires going back to the drawing board. If you run into uneven or blotchy paint, the best thing to do is start over.
So, a second paint coat will make the finish look darker and more intense. Think of adding multiple coats of paint to your wall as adding an extra shot of espresso to your morning coffee – adding more intensity to your coffee – and your paint colours!

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.
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.
Changing Colours
So again, two coats is an absolute rule. If it's crazy drastic (i.e. you're going from black to white, or eve white to yellow for example) you might need three. There really is nothing worse than the old colour finding itself through, so be thorough.
The additional coverage you get from a second coat of paint will help fill in any areas you missed with the first coat, creating a more uniform finish. As a result, you will lessen the appearance of roller marks when the paint dries.
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.
Color Considerations
We all know that lighter colors emphasize imperfections while darker colors hide them. This also has to do with light and reflection. Lighter colors reflect more light while darker shades absorb it.
If the humidity is too high, the solvents in the paint will take longer to evaporate. This long drying time cause the paint to dry with a darker appearance, though it can also lead to uneven drying, streaks, and paint discoloration.
Eggshell finishes provide a slight sheen while still concealing minor flaws. Reserve glossy finishes for trim work and areas with minimal texture concerns. Each finish type serves a distinct purpose in creating smooth-looking surfaces throughout your home.
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.
You'll need to give the first coat ample time to cure before adding the second. How long you'll need to wait depends on the type of paint you use: Usually, you can apply a second coat of latex (water-based) paint two to four hours after the first. With oil-based paints, it's best to wait a full 24 hours between coats.
It is common advice to use two coats of paint on most projects.
Applying the second coat too early will result in streaks, peeling paint, and uneven color. Not only will this ruin the entire project but it'll cost additional money to get more paint in some occasions. It's best to wait for the first coat to dry.
This may be due to any of the following factors: Moisture trapped beneath the surface of the paint film. If the paint is applied over a powdery or friable surface. Surface contamination such as dirt, oil, and grease.
Matte. This flat finish is great for hiding surface imperfections, while its angular shine helps make walls smooth and washable. Use this sheen for: Living rooms.
Paint designed for uneven surfaces may be sold under a range of names including elastomeric paint, high-build paint, crack-free paint or renovation paint (which is basically a filler and undercoat in one). These paints are much thicker than ordinary paints which gives them much better coverage.
Flat paint, with its velvety, matte appearance, is the best choice for hiding any wall imperfections due to its lack of shine and reflective properties.
