Painting

When painting, use a brush (a 4-inch brush is the norm) to paint the top edge of the wall, the corners where two walls meet, and the edges where trim has been applied to the wall. A paint roller cannot get into a corner well, so you'll need the brush to get the paint there.

For a more even look, after cutting in with the brush, go back over the area with a very dry roller. This will change the texture to match the rest of the wall.

Paintable or non-paintable caulking?

Choosing the right caulking - paintable vs. non-paintable - is a critical first step in any sealing job. Why? Because a good-quality non-paintable caulking is most likely made of silicone, which will not hold paint. Good-quality paintable caulking, on the other hand, is typically made of acrylic latex. That material will hold paint beautifully, but it will not stand up to weather, water, heat and cold very well unless it is painted.
