Structural Steel Painting — Direct Answers
What is structural steel painting?
Metal building painting recoats pre-engineered steel buildings, structural steel, and metal-clad commercial structures — using DTM acrylics or two-component urethanes specced for the substrate's existing finish (Kynar, polyester, galvalume).
Why does structural steel painting fail?
- Painting over chalky Kynar without a bonding primer — peels in a year.
- Solvent flash off in summer heat — paint film cracks and pinholes.
- Skipping solvent wipe — silicone or oil contamination causes fisheyes.
What does structural steel painting cost?
$2–$5 per square foot. A typical 60x100 metal commercial building: $14,000–$35,000.
What products should be used for structural steel painting?
- Sherwin-Williams Pro Industrial DTM Acrylic — workhorse DTM for sound metal
- Sherwin-Williams Sher-Loxane 800 — two-component polysiloxane for premium long life
- Sherwin-Williams Pro Industrial Acrylic Bonding Primer — for chalky Kynar/polyester
How long does structural steel painting last?
10–15 years on properly prepped metal with DTM Acrylic; 18-25 years with Sher-Loxane 800.
What preparation is required for structural steel painting?
- Power wash and solvent wipe
- Test chalk with the cheesecloth pull test; if heavy, prime with bonding primer
- Spot-prime any bare or rusted steel with corrosion-inhibiting primer
What maintenance is needed for structural steel painting?
Annual wash. Touch-up any scratches or screw heads to prevent rust bleed. Recoat at year 12-15 (DTM) or 20+ (Sher-Loxane).
