10 Things You Need to Know Before Spray Painting
You’ve most likely never heard of Bonnie Seymour, but she did you a huge favor. In 1949, she suggested that her husband try putting paint in an aerosol can. He did, it worked, and painting got a whole lot easier. Here are some key tips for success with Bonnie’s brilliant invention.
Plastic Paint Works!
Conventional spray paints just won’t stick to plastic. Now paint manufacturers offer paint just for that application. These paints don’t just stick; they fuse with the plastic surface to form a super-strong bond. Krylon Fusion for Plastic and Rust-Oleum 2x are two common brands.
Light Coats and Patience Prevent Runs
Elevate your work (inset) Don’t set your project directly on a workbench or newspaper; the paint will glue it to the work surface. The best way to prop up wood furniture is to drive screws into the legs.
Don’t Swing an Arc
It’s the most natural motion for your arm, but swinging gives you heavy coverage in the middle of the project and light coverage at the ends. So move the can parallel to the surface, concentrating on straight, steady motion.
Get a Handle
If you’ve ever sprayed a project that required several cans of paint, you already know about finger strain. For less than five bucks, a trigger handle not only prevents the pain but also gives you better control of the can.
Wear a Respirator
Start Before; Stop After
Smooth a Rough Surface
If you want a smooth finish, pick the right primer. Some are formulated to fill pockmarks and scratches. Plus, they’re sandable so you can smooth the surface before top-coating with paint.
Two Cans are Faster?and Sometimes Better
Spray-painting a big surface isn’t just slow; it can also lead to texture trouble. In warm, dry conditions, spray paint dries almost instantly, so very light ‘overspray’ may land on nearby paint that’s almost dry. When that happens, you get inconsistencies in the surface texture.
Here’s how to get paint onto the project faster and get a consistent finish: Just hold a can in each hand. If you move each hand independently, one hand will stray off course. But if you hold the cans together, creating a single spray pattern, it’s easy to stay on track. Keep in mind that this trick can lead to drips on vertical surfaces. Make faster passes and try a practice run on a scrap of cardboard.
