Stripping Old Paint

If you're fortunate, your home might only need a thorough cleaning before repainting. Rinse it with a hose and scrub away stubborn dirt with a brush and warm, soapy water, or use a pressure washer. If not, prepare for a more labor-intensive, messy task. However, if done correctly, your new paint job will not only look better but also last between five to eight years on average.

Begin by closely inspecting the exterior of your house or any outbuildings. Check not only the walls but also the eaves, windows, doors, and foundation. Look for issues such as cracked shingles, damaged siding, popped nails, peeling or bubbling paint, mildew, or rust stains. After identifying the problem areas, roll up your sleeves and get to work on the repairs.

Scraping Paint

Use a wire brush and a broad putty knife to scrape off small areas of damaged paint. Focus on the gaps between clapboard siding and areas like downspouts and gutters. For quicker work on metal surfaces, attach a wire brush to an electric drill to remove both rust and paint with less effort. For larger paint removal tasks, consider a sharp pull scraper, a tool with a replaceable blade designed to strip old paint down to bare wood with a single pass. Hold the scraper perpendicular to the wood, applying firm pressure as you drag it along the surface, keeping the blade flat to avoid gouging the wood.

Sanding

To smooth out edges of scraped areas, wrap sandpaper around a wooden block. For larger surfaces, it's less tiring and more effective to use an electric orbital sander, moving it in an up-and-down or back-and-forth motion to remove paint and smooth edges. Avoid using a disc sander or belt sander as they can leave marks or dips in the wood that will show through when repainted.

Melting

For especially thick layers of paint, heat may be more effective than physical effort. One option is using an electric paint remover, a tool with a flat heating element that "cooks" the paint and includes an integrated scraper to remove it. Wearing heavy gloves, place the heating element on the surface until the paint starts to sizzle. Then, pull the device firmly across the surface, allowing the scraper to lift off the softened paint as you move along.

Liquid Paint Removers

Liquid paint removers should only be used as a last resort. While effective, they are costly, especially for larger projects. Additionally, they can drip onto areas of good paint, creating additional problems to address.

Priming

After removing all loose paint, apply the appropriate primer to any damaged areas, particularly if your paint removal process has exposed raw wood or bare metal. The type of primer you select depends on the type of paint you plan to use later. Use latex primers for latex paint, solvent-based primers for solvent-thinned paints, and metal primers for metal surfaces. These primers not only offer additional protection from the elements but also provide a solid base for the finishing coats of paint. Priming is also necessary when working with new wood.
