If your home has wood siding, you probably already know the drill: every year or two it has to be cleaned, scraped, sanded, and repainted to keep the exterior looking great. Whether you’ve repainted your Carolina house numerous times in the past or this is the first time you’ve had to, it’s not a bad idea to research the proper exterior scraping and sanding methods.

The more you know about how to correctly go about this process the more likely you are to end up with a successful paint job that lasts for at least a couple of years. If you are only painting a small feature, such as architectural gingerbread details, you can expect your new paint to last even longer. Hopefully, these tips will help you maximize your money and effort next time you have to paint the exterior of your residence. 

Clean the siding first

Before you start scraping and sanding your wood siding, you should clean it. Although there are several reasons for this and it is simply good practice, one of the primary benefits is that it will protect you. Even with safety goggles, flying dust and debris from dirty siding can result in skin or eye irritation. The very best way to clean your house is to pressure wash it. Barring that, use a solution of seven parts water to one part TSP-based cleaner and scrub the siding manually. 

Scrape in every direction

Removing all of the old paint before a new coat is applied is essential to the success of your project. If old pieces of paint, even seemingly small flakes, are left behind, it could jeopardize your upcoming paint job. Bubbles and cracks could begin to form almost immediately due to uneven application, for instance. To make sure you get every bit of old paint off, use a high-quality paint scraper in every direction. To avoid gouging the wood siding boards, press the edge of the blade flat as you scrape. 

Use the right sanding tools

There are certain sanding tools that will make your job easier. Make sure you use these instead of substitutes that may not work as well on wood siding. A 5-disc power disc sander that can be used with both 7-inch and 5-inch blades is the best choice. The larger blades should be used for the majority of the project, with the smaller blade being reserved for detail work. 60-grit sandpaper will work for most of your project, but you may want to have some 100-grit in on hand in case you run into particularly rough sections.
