Wash the exterior of your house with soapy water and a scrub brush to remove any dirt. Allow the surface to dry completely.
Check the weather forecast for suitable conditions. Look for a few days in a row of dry, still, 70-degree weather.
Apply exterior primer with a roller. Use a roller sleeve with a long nap for textured surface, such as brick and stucco. Use a sleeve with a medium nap for regular, semi-smooth surfaces.
Use a paintbrush to paint between bricks, under eaves and along any exterior trim. A brush with natural bristles works better with oil-based products. Choose a synthetic-bristle brush when using latex and other water-based paints.
Read the directions on the primer regarding its required drying time. Wait the minimum time suggested before applying the finish coat paint. The paint and the primer bond better when you apply them in quick succession.
Roll the paint on with rollers, using an appropriate sleeve for each kind of surface. Use a brush to reach narrow areas where the roller can't fit.
Apply two coats of paint if necessary. Making sure that the coverage is adequate could give your paint job greater longevity.
