❓ How to Use Thermcoat

🧴 Prep the Can: Before starting, ensure the can is at room temperature (around 68°F / 20°C) for best performance.

🔄 Shake Well: Vigorously shake the can for at least 30 seconds to properly mix the contents.

🔫 Set Up the Gun:

  • Attach the can to the applicator gun securely.
  • Fix the appropriate spray nozzle (Nozzle A for vertical surfaces, Nozzle B for ceilings).
  • Hold the can upside down while spraying.

🎯 Adjust Foam Flow: Use the trigger and the adjustment screw on the back of the gun to control foam output.

📏 Spray Distance:

  • For vertical applications, spray from 12–18 inches (30–46 cm).
  • For horizontal applications, spray from 6–8 inches (15–20 cm).

📐 Apply in Layers:

  • Spray foam in multiple thin layers rather than one thick coat.
  • For optimal insulation, apply at least three layers to reach a total thickness of around 2 inches (5 cm).
  • Allow each layer to expand and partially cure before applying the next.

🧼 Clean Immediately: After use, clean the spray nozzle and applicator gun with foam cleaner to prevent clogging and ensure longevity.
