When this system may fit

Is this the right assembly?

  • A metal roof is weathered, leaking at seams or fasteners
  • The panels are structurally sound and worth restoring
  • A reflective finish is wanted to reduce heat gain
  • Tear-off is undesirable or unnecessary

These are indicators, not a specification. Suitability is confirmed by a project review.

Performance

What it delivers

  • Seals seams, laps and fasteners
  • Addresses and inhibits corrosion
  • Reflective, cool-roof finish options
Limitations & considerations

Where to take care

  • Severe or structural corrosion may require panel replacement
  • Requires thorough surface preparation
  • Weather-dependent cure
Weather & cure conditions
  • Apply within the specified conditions; avoid dew and rain before cure
  • Account for thermal movement of metal
  • Observe recoat windows
Quality-control checklist
  • Corrosion treatment verified
  • Fastener and seam reinforcement inspected
  • Coverage / film checks
  • Final inspection
