💡 Instructor Insights

  • Drywall specs (09 29 00) typically outline thickness, taping, and fire ratings.
  • Acoustical ceilings and tile floors often cross-reference finish and mechanical sections — check closely.
  • Paint systems include primer, base coat, and finish — confirm sheen and VOC compliance.
  • Floor finishes may list adhesives and moisture barrier requirements — don't skip!
  • Look for transition strip details between different flooring types.

Division 09: Finishes

🔹 Key Teaching Points

1️⃣ Drywall Specs Define Performance

  • Spec section 09 29 00 includes gypsum board types, thickness, and taping requirements.
  • Check for fire-rated assemblies and Level 4 or 5 finish requirements.

2️⃣ Coordination is Key for Ceilings & Tile

  • Acoustical ceilings and tile flooring specs often reference Division 23 (HVAC) and Division 26 (Electrical).
  • Look for MEP clearance and layout coordination in ceiling plans.

3️⃣ Paint Specs Include More Than Just Color

  • Check primer, number of coats, base finish, and sheen (flat, eggshell, semi-gloss).
  • VOC limits are often required for LEED or health compliance.

4️⃣ Floor Finishes Come with Layers

  • Specs may call out adhesives, crack isolation, and moisture barriers below the surface.
  • Read carefully for required underlayment or substrate prep.

5️⃣ Transitions Matter

  • Between carpet and tile? Vinyl and concrete? Transition strip details are typically buried in finish notes.
  • Improper transitions lead to tripping hazards or failed inspections.

✅ Wrap-Up Summary

  • Division 09 covers all interior visual and functional finishes — from drywall to flooring.
  • Specs define material layers, performance, and even sheen levels.
  • Missing finish info can cost you rework, lost time, or code violations.
