• Document existing coating system type, condition, adhesion, and DFT by XRF testing for lead content.
• XRF lead paint survey on all pre-1978 buildings before any paint disturbance; EPA RRP rule compliance.
• Adhesion testing (ASTM D4541) and DFT measurement (ASTM D7091) on existing coatings.
• Sample boards: produce paint system sample boards for Owner color and sheen approval before production.

• Interior: TSP or chemical wash; sand all glossy surfaces; fill cracks and holes; spot prime.
• Exterior masonry/wood: pressure wash minimum 2,000 psi; scrape all loose paint; prime bare areas.
• Steel: abrasive blast per SSPC-SP grade required by coating system; verify dry, clean surface.
• Lead paint management: EPA RRP-compliant containment, HEPA vacuum, disposal; certified RRP firm required.

• Apply primer to all bare and previously painted surfaces per MPI specification.
• Apply 2 finish coats; between-coat sanding on Level 5 surfaces; minimum MPI Gloss Level 3 on walls.

• Exterior wood: oil-based primer on all bare wood; 2-coat acrylic topcoat; back-prime all replacement boards.
• Steel: per protective coating system (Trade 12) — zinc primer + intermediate + finish if full system required.

• Historic color research: chip analysis, archival record research, custom color matching for preservation projects.
• Anti-microbial coatings: for healthcare, food service, and clean-room environments.
• Epoxy floor coatings: industrial-grade; chemical-resistant; slip-resistant aggregate broadcast option.
• LEED/WELL compliance: specify low-VOC products; document for IEQ credits.
