I've chosen a nice, dark decor paint for my dining room, but it doesn't seem to cover the color of the wall underneath. I've done four coats and I'm still not happy with the results. What am I doing wrong?

In order to achieve the deep, rich colors in decor paint, it is necessary to leave the white pigment out of the paint. Yet it is this white base pigment that gives the paint its ability to hide what was on the wall before. The solution? Always use a top-quality primer paint before a color decor paint. In fact, you can even tint the primer slightly in the direction of the final coat. The primer will completely cover what was there before and present an even surface that is easy to cover with the decor paint. Using this trick, you will get results with one, or at most, two coats of decor paint.
