Using primer helps the topcoat stick better and last much longer. Never paint when it's raining. Let the house dry for 2-3 days if it has rained recently. This will be more comfortable, and prevent the paint from drying too quickly. Nylon and polyester bristle brushes work better with latex paints.
Natural bristles work better with oil-based.
Flick loose bristles out of a new brush before you begin painting with it. Ask for some empty paint cans to pour the paint into when painting. Always wait the number of hours recommended by the paint manufacturer before applying a second coat of paint. Two layers of topcoat are usually preferred over one for optimum protection.
