Start at the top corner of the project area, and cut in a three- to four-inch wide area around the perimeter with a brush.
Working in a three-by-three area, apply a "W"-shaped pattern toward the top of your wall, or the section to be painted.
Start filling in the width of the "W" pattern, from top to bottom, and continue until the area is completely covered.
Start in the top corner of the project. Cut in a three- to four-inch wide area around the perimeter with a brush, including any grooved or lapped areas.
Then, place a loaded roller near one corner of your project, approximately three to four inches from where you cut in. Roll side-to-side, or top-to-bottom, following the direction of the siding, until complete.
When you are nearing the end of one container of paint, find a natural break in your project, such as a corner or the end of a section of trim.
Open a second container and mix it into the paint from the first container. Stir well.
If you have a drip on a painted surface that's still wet, you can feather it out using your brush, or gently roll over the drip with your roller.
If drips are dried, you may have to scrape the drip off and touch up the spot with fresh paint. Do not pull the drip. Instead, scrape and sand the area.
