Frequently asked questions
- Do I need to scuff paint before priming?
- Lightly scuff and clean per your urethane system TDS. Avoid bare metal unless specified. If metal is exposed, follow rust-inhibiting steps before primer.
- What temperature and humidity is ideal?
- Many systems prefer about 70°F (21°C) with moderate humidity. In cold temps, use approved fast-cure options or increase cure time.
- How do I avoid corner gaps?
- Maintain bead height through corners and overlap your start and stop by about 1 inch (25 mm). Keep the nozzle angle consistent to avoid thin spots.
