You will want to use the highest quality exterior home paint your budget will allow for your project -- not only because it will look the nicest, but also because it will save you money in the long term by offering better coverage and durability. Better coverage means fewer coats and fewer work hours for your painter; better durability means that you won't have to spend money to paint the exterior of your home again in just a few years. How do you know how much paint you're paying for? Here's some helpful math:
David took so much pride in his work and was really wonderful about communicating with us each step of the way. His crew painted the interior AND exterior of our home in maybe a week or less. I love how they painted our pipes outside of the house to match the colors- I'll attach a picture to show what I mean. Their attention to detail was fantastic! They seriously did not miss a spot and there was zero paint in any place that it wasn't supposed to be!
Deciding which paint to use has gotten much easier now that acrylic latexes have pushed oil-based paints almost to extinction. The acrylics offer superior performance (they don't harden with age, the way oils do, so they move and breathe without blistering), they don't mildew as readily, and they emit fewer VOCs, so they comply with new air-quality regulations. They also work over both oil- and water-based primers.
For smoothing the edges of scraped spots here and there, you can wrap a piece of sandpaper around a wood block. For larger areas, it's less tiring and more effective to use an electric orbital sander. Move it up and down or back and forth across the surface to remove old paint and smooth rough edges at the same time. Don't use an electric disc sander or a belt sander. Both can leave swirls or dips in the wood that will show through a new coat of paint.
As any painter will tell you, prep work is just as important -- if not more important -- than the paint application itself. If the paint on your house is chipping or peeling, it needs to be scraped and sanded smooth before applying a new finish. In most cases, you won’t need to remove all the existing paint, but scraping, sanding, patching, caulking, and priming are critical steps that take place before the start of most exterior painting jobs.
