Surface Preparation Guide

Why Surface Preparation Matters

Proper surface preparation is the foundation of a successful painting project. Even the highest quality paint will fail if applied to a poorly prepared surface. Taking the time to properly prepare surfaces ensures better adhesion, smoother finish, and longer-lasting results.

Pro Tip

Surface preparation can take up to 50% of the total project time, but it's worth every minute. A well-prepared surface can make the difference between a paint job that lasts 3 years versus one that lasts 10+ years.

Preparing Different Surface Types

Each surface type requires specific preparation techniques to ensure optimal paint adhesion and longevity.

Drywall/Plaster

Drywall and plaster surfaces are common in interior spaces and require careful preparation.

Tape and fill joints with extra hardening compound
Fill holes and cracks with spackling compound
Sand smooth when dry
Remove dust with a damp cloth
Apply primer, especially for new drywall
Sand lightly between coats

Wood

Wood surfaces require special attention to prevent issues like tannin bleed and moisture problems.

Sand in the direction of the grain
Fill holes with wood filler
Clean with a tack cloth to remove dust
Apply wood primer to prevent bleed-through
Sand lightly between coats

Metal

Metal surfaces are prone to rust and oxidation, making proper preparation crucial.

Remove rust with wire brush or sandpaper
Clean with solvent to remove oils
Apply rust-inhibiting primer
Allow proper drying time between coats
Use metal-specific paint for best results

Previously Painted Surfaces

Existing paint requires assessment and proper preparation before repainting.

Remove loose or peeling paint
Sand glossy surfaces to create tooth
Clean thoroughly to remove dust
Prime bare spots or significant color changes
