As you scrape, you may find that the wood has turned gray or black in some areas. Check for rot by probing these areas with a nail. Spots that are discolored but firm are simply weathered. Weathered wood doesn’t hold paint very well, so sand away the gray surface. If you find soft areas, you’ve got rot. Small, shallow soft spots can be dug out and repaired with a two-part filler such as Minwax High Performance Wood Filler. But when rot is deep and widespread, it’s best to replace the entire piece of wood.
Climate is another factor to consider. Sunlight, wind, rain and salty weather can all wear out exterior paint. Oil-based paint is durable against wind, rain and temperature changes, but sunlight tends to degrade it. Alkyd paint chalks and sheds very thin layers when it begins to wear. Latex paint is the more durable option for very sun-drenched and relatively dry climate areas. Latex paint with high vinyl content should be avoided, however. Acrylic resin is by far the more durable binder for outdoor latex paint.
A qualified exterior house painter can walk you through the process of getting your house ready for a new coat of paint, from scraping and sanding to patching and priming. A pro can also recommend the best exterior paint for the job, whether your siding is wood, fiber cement, stucco, vinyl, or even metal. When it comes to getting the work done, your painter will arrive with all the tools and equipment needed to get the job done quickly, correctly and safely.
The best time of the year to paint your home is typically in late spring and early summer when it’s warm outside and moisture is low. This can change based on your geographic location. For example, fall can be a good time to paint in California when the difference between high and low temperatures is low. Your painter will select the optimal time to start your exterior painting project.
