Sealers and primers are essentially the same. They’re both preparatory coatings that seal the surface, provide better paint adhesion, and prepare it for the succeeding topcoat. The only difference is that most Boysen sealers are clear coats while Boysen primers are pigmented.

Deciding which product to choose between a sealer and a primer depends on the aesthetic that you want to achieve, the type of surface you’re painting on, and the paint products that you’re using. For example, if you want to highlight the natural beauty of wood, use a sealer like Boysen Lacquer Sanding Sealer with Boysen Wood Varnishes. But if you want to add a vibrant splash of color to your home, paint your wooden furniture with a primer like Boysen Flatwall Enamel with Boysen Quick Drying Enamel as your topcoat.

Regardless if you use a primer or a sealer, you have to make sure that you completely prepare the surface. Read about surface preparation here to see some easy steps to prepping different kinds of substrates.

Boysen Sealers for Wooden Surfaces
