Best deck staining pros near Fairfield, ID

Many decking oils can help slow down algae growth, but they don't completely stop it. These oils work by sealing the wood, which reduces moisture and, therefore, algae growth. Some decking oils also help protect against UV damage, but they need to be reapplied according to the manufacturer’s instructions to ensure the decking stays protected.

You can paint over old paint on a concrete porch. For the best results, you should first clean the surface and remove as much paint as you can. A power washer is helpful here, but you’ll also want to scrape as much of the old paint away as possible. Then you should prime the porch before repainting it.

Whether you can paint over your existing paint depends on what’s on there. Most of the time, you’ll want to sand down or scrape off the paint that’s currently coating your surface. Epoxy paint, for example, won’t let new paint stick to the surface. Latex paint is more forgiving and will accept a new coat, but a primer is recommended if you’re switching colors.

Wood stains last anywhere from two to five years, depending on exposure to the elements, your local climate, the type of stain, and the surface it’s on. For instance, vertical surfaces last longer than horizontal surfaces. Some types of woods, like dense hardwoods, will require a recoat yearly, as they are too dense for the stain to absorb. In any event, apply a recoat every 2 to 4 years. As for storage, a can of unopened stain can last up to 5 years, though results may vary.
