When I was a kid one of my summer jobs was painting and staining decks and cottages. I’d arrive in my little tin boat and spend a day scraping off peeling paint and stain, maybe sanding a few rough edges before slapping on a new coat of finish. Two days work, easy cash. After all, what’s so hard about painting, right? Pick your colour and get rolling, or brushing or spraying. Done and done — if you can make the decision.

But not quite. I bet most of the exterior paint jobs lasted a season or two—at best; more likely, the finish was coming off before Thanksgiving closedown. Unless you want to repaint every year or be left with a spotty, craggy finish, exterior painting requires both mental and physical prep work, as Katie at Besotted Cottage found out. Here’s the scoop.

Step 1: Wood Inspection

Before you argue with your spouse over which hue of green best matches the dog’s fur, trek down to the hardware store and purchase a $30 moisture meter. These simple-to-use (think of those BBQ fork thermometers) devices check the moisture level of the wood. If the wood is too wet, paint won’t adhere properly. As a general rule, if the wood has more than 16 per cent moisture, it shouldn’t be painted. If this is the case, wait until later in the summer, when the wood is dryer from summer sun.

Step 2: Scrape

Scraping is perhaps the most straightforward task. For really loose paint, a simple flanged scraper works well; for harder-to-remove surfaces, use a sharp hook-type scraper. Scraping quickly dulls the blade, so if you’re working with a large area, keep checking the blade to make sure it’s not dull, and keep scraping until the old paint is removed.

For really stubborn areas, you can use an electric heat gun, but make sure you’re wearing a proper face mask to prevent against inhaling dangerous fumes from old oil and lead paint. As well, be aware that a heat gun can burn the wood, so keep water on hand to douse any flames.

Also, a word of warning: don’t fiddle around with sandblasting or chemical paint removers. These are professional-level tools that can easily ruin the wood if you don’t know what you’re doing. If the job requires this level of removal, consider hiring a pro.
