Choosing primer is often the last consideration for most home projects. Most Benjamin Moore products are self priming, making primer unnecessary in most projects. With how versatile Benjamin Moore paints are, it can be easy to see primer as just an added cost. For the most part, each primer is formulated to adhere to difficult surfaces, forming a new easy to bond to surface for paint. Today, we’re going to talk about the main situations where primer is going to save you money and improve your paint’s longevity!

Difficult Surfaces

  • Drywall – As it’s name implies, drywall is naturally porous and dry. The paper substances act like sponges, soaking up excess water from the environment. This dehydrates the paint extremely quickly, breaking it’s chemical reactions. From cracking to alligatoring, and even turning the paint into a chalky powder. Most primers are dry wall resistant, and, there are many types of low cost drywall specific primers to choose from!
  • Plastic and Metal – Smooth surfaces are difficult for paint to adhere to. Paint forms a sheet that bonds to imperfections in the surface, and, the materials themselves are often chemically incompatible with bonding agents in normal paint. When you paint these surfaces, the paint might seem watery, running down the surface, or, in many cases, the paint will dry, but, not be bonded to the surface! The paint might just peel away, in the worst cases! These require more specialized primers, with different bonding agents. Look for “All Surfaces” or “Metal and Plastic” on your primer’s directions to be sure!
  • Damaged Walls (Mold, Water, Smoke and more!)  – Painting over significant or deep damage is always a bad idea, but, if you’ve got a few trouble spots in your home, primer might be a solution! Light mold can often be fixed with specialized antifungal primers. All three types of damage are fairly similar in that they need primer that is engineered to completely seal the surface it is covering. These primers are often difficult to work with, sticking aggressively to any surface it comes in contact with.

When working with primer, always remember to use sandpaper to lightly rough the surface of the primer up. This will greatly increase how well your paint bonds to the primer, giving it nice grooves to fill in and adhere to.
