Surface Preparation Checklist for Flawless Interior Painting

Every interior project starts with a measured walkthrough where we document existing substrates, lighting conditions, and environmental risks. We map walls that require resurfacing, note existing finishes, and capture moisture readings anywhere we suspect hidden leaks.

Plaster repairs and drywall patches follow a phased approach: we open joints, embed fiberglass mesh, apply setting-compound base coats, and finish with ultra-fine topping compound. Between each lift the surfaces are sanded under LED raking lights so imperfections show up before paint goes on.

Priming is where longevity is won or lost. Kitchens and baths receive moisture- and mildew-resistant primers, high-traffic corridors get bonding primers that keep color coats locked down, and accent walls with bold hues are back-rolled to ensure texture consistency.

Key Points

  • Moisture and alkalinity testing prevent hidden failures.
  • Mesh-reinforced patches outlast quick skim fixes by years.
  • Finish sanding under directional light ensures glass-smooth walls.

A clean, well-primed surface reduces paint touch-ups by up to 60% in the first year.
