Frequently Asked Questions
- Do I need to scuff paint before priming?
- Lightly scuff and clean per your urethane system’s TDS. Avoid bare metal unless specified; if exposed, follow rust-inhibiting primer steps.
- What temperature/humidity is ideal?
- Most systems prefer ~70°F/21°C with moderate humidity. In cold temps, use manufacturer-approved fast-cure options or increase cure time.
- How do I avoid corner gaps?
- Maintain bead height through corners and overlap your start/stop by ~1 inch (25 mm). Use proper nozzle angle to prevent thin spots.
