If you decide to paint over wallpaper, it’s important to prep the surface with an oil- or shellac-based primer. This helps prevent moisture from creating bubbles loosening the adhesive. Plus, a primer helps paint attach to the wall smoothly and securely. Use quality oil-based or latex paint to cover the wallpaper. Be prepared to cover the wallpaper with two coats for maximum coverage.

Use at least two coats of paint for exteriors for better coverage and added durability. When painting lighter colors over darker colors, a third coat of paint may be necessary to achieve full coverage of your home’s exterior. A durable paint specifically designed for the material of your home’s exterior will last the longest.

In most cases, paint primer is necessary before painting over wood paneling. A hardy primer formula covers up stains and leaves a grippy surface for the new paint to hold onto. If you don’t use a primer first, you risk poor adhesion, visible blemishes, and a paint top coat that could flake away later. 

There are two primer choices: oil-based or latex-based. Choose an oil-based primer for durability and adhesion, but prepare for extra dry time and more VOC (volatile organic compounds) fumes. Or, pick a stain-blocking latex primer. They’re easy to apply, clean up, and affordable.

Like any paint, the magnetic type has a shelf life. Depending on the formula and manufacturer, the paint can last between 12 months and 5 years for an unopened can. But even magnetic paint with a five-year shelf life can go bad sooner, depending on the storage location and temperature. Opening the tin and improperly resealing it also expedites expiration.

If your paint smells funky and is still lumpy after stirring, this is a sign it isn’t usable anymore.
