Use a dropcloth to cover plants, shrubs, porches, roof sections, sidewalks, driveways or other surfaces. Alejendre tells his customers to paint an area of 3 to 5 square feet and then move on. I tell them to make the pattern of an 'm' and then roll up and down twice. And keep the roller full at all times. Don't be shy using the paint.
Some people try to squeeze every drop out of a brush or roller before they refill it.
This results in an uneven distribution of the paint. When a roller is used for most of the wall and a brush for the corners, the color may not be uniform. To help blend the brushed edges with the rolled area, work with a partner. Start out with the brush, reaching in to tight spaces, then have someone follow close behind with the roller, overlapping the brush-painted area before the paint can start to dry. Alejendre says not to use inexpensive, low-quality paint.
