What preparation do I need when painting the exterior of my house?

If your home’s exterior is looking tired, it may be time to improve its appearance with a fresh coat of paint. Properly preparing your home’s exterior for painting is the key to ensuring that paint adheres to your surfaces for a perfect finish. Fortunately, preparing your home’s exterior for painting is easier than you might think. Follow the steps below to get started.

Begin your preparations by removing any mailboxes, house numbers, planters and light fixtures to a safe location. Place canvas drop cloths under any areas you plan to prepare for painting to protect against drips and spills.

If your walls are made from rock, bricks or masonry, inspect your mortar for damage. Fill in any cracks and holes and allow sufficient drying time before washing. If the damage is deeper than 10 millimeters, you may need to build up the filler in layers, allowing sufficient drying time between applications.

Lightly sand glossy or shiny surfaces for better paint adhesion. You should also sand any mill glaze off new siding.

If your masonry or brick surface is streaked with efflorescence, remove it using a high-pressure water cleaner. Alternatively, scrub the surface with a wire brush and water.

Clean your walls, gutters, eaves and downspouts using a high-pressure water cleaner and a detergent. When using detergent, remember to follow the manufacturer’s instructions and wear appropriate protective clothing, if necessary. Treat any areas of mold, algae, moss or lichen growth with a fungicidal wash.

Seal and prime powdery or porous surfaces with a primer that’s appropriate for the surface you’re painting and the paint you’re planning to use. You should also prime any exposed areas where the paint has worn thin or peeled. When applying primer, use a small paint brush for any edges and hard-to-reach areas and a long pile roller for larger areas.
