Using the Wrong Paint
If you've chosen the wrong paint for the job, no matter how good your application technique is, the project isn't going to turn out well. Here are three situations to watch out for:
1. When painting surfaces that aren't perfect, don't choose paint with a high sheen. The glossiness will only accentuate the problems on the surface. Light reflecting off the shiny paint will highlight every defect. So if you want to paint with a semigloss or gloss sheen, make sure the surface you're painting is carefully prepared and perfectly smooth.
2. When covering a light-colored wall with dark paint, start with a tinted primer. Ask at the paint store for advice. The staff will know what tint to use. Gray primer is a great choice under most dark colors.
3. If you're painting with two sheens of the same color, be sure to label the cans. It's really
easy to get the two mixed up, and you won't realize your mistake until the paint dries. You'll be really sorry if you accidentally touch up flat walls with semigloss paint.
