Step-by-Step Painting Process

1. Surface Preparation

• Sand the surface with:
  
  • 80-grit sandpaper for rough surfaces
  • 120-grit for medium smoothing
  • 220-grit for final smoothing
• Remove all dust with a tack cloth
• Fill any voids or knots with exterior wood filler
• Sand filled areas smooth

2. Edge Treatment

• Sand edges smooth
• Apply edge sealer to all cut edges
• Consider using wood putty for smoother edge appearance

3. Priming

First Coat:

• Use exterior-grade primer
• Apply with:
  
  • Brush for edges and details
  • Roller for large surfaces
  • Follow grain direction
• Let dry completely (usually 24 hours)

Second Coat (recommended for maximum protection):

• Apply second primer coat
• Sand lightly between coats
• Ensure complete coverage

4. Painting

First Coat:

• Use high-quality exterior paint
• Options include:
  
  • Latex paint for general use
