A San Francisco painter shows How to paint interior problem surfacesIn this article, we address how to paint interior problem surfaces so you get better results. By problem surface, we are referring to substrates that are loose, unsound, chalky, water-damaged and the like. Applying patching compound or paint over these surfaces is not recommended and will lead to a poor finish. The result will surely be a finish that bubbles, peels, or flakes off.

As painting contractors, we deal with interior problem surfaces inside many old homes. As a result, we often face repairs to bubbling, flaky, or unstable problem surfaces. Zinsser Gardz Problem Surface Sealer is our “go-to” product for fixing paint surfaces . For instance, it helps with old wallpaper layers, water damaged or torn drywall, crumbling plaster and other situations involving unstable walls. This low odor, water based formula dries to a clear, matte finish. As a result, this creates a hard seal over damaged drywall, adhesive residues and other chalky surfaces. Some uses include:

  • Repairs torn paper on damaged drywall, eliminates bubbles
  • Seals skim coats & spackling
  • Protects new drywall
  • Seals old wallpaper adhesive

We use Zinsser Gardz when we paint interior problem surfaces. Remove as much of the unstable surface as possible, apply the product and allow it to dry. Next, use patching compound, prime and paint and enjoy your work!
