1 – Mix cans of paint of the same color
Even though you purchase several cans of paint with the same color, the color may still be slightly different from can to can. Therefore, it is advisable to mix all of the paints of the same color together before applying them on the surface. If you don’t do this, then there might be a visible difference if you apply one can of paint on a part of the surface, and then another can of paint on another part of the surface. Solve this problem by mixing the paint from all the cans beforehand.

2 – Prime and texture patches on the wall
While color may look evenly applied on the surface, the sheen will not look uniform and might look blotchy when walls are freshly painted. What causes this? Wall patches. Those patches might be there from applying fillers over cracks and holes on the wall. These fillers are porous and they absorb the paint, therefore creating a dull surface. How do you avoid this problem? By priming and texturing wall patches first before applying paint.  In doing so, the texture of the surface becomes more even throughout.

3 – Cut the tape loose before pulling it off
Beware of pulling the tape off the trim when the paint dries. Doing so might tear pieces of dried paint from the wall. Instead, wait for at least 24 hours for the paint to dry and then use a sharp knife to slice the border between the painted surface and the tape. After doing this, you may pull off the tape.

4 – Paint the trim first
Do not immediately paint the walls and the ceiling. Instead, paint the trim before anything else. This is because it is much faster and easier to tape off the trim than the walls. After the trim is painted and it dries for at least 24 hours, you may tape it off and then get to painting the ceiling and the walls.

5 – Sand trim between coats
To achieve a really smooth surface texture, you should sand the trim between coats. Otherwise, you will end up with a grainy finish. Use a fine-grit sanding sponge to sand the trim. After, put on the first coat of paint and let dry for at least 24 hours. Sand the trim lightly, and then apply the second coat.
