Best Practices:
- • Always use primer on new or stained surfaces
- • Apply thin, even coats to avoid drips and runs
- • Allow proper drying time between coats (2-4 hours)
- • Use proper roller nap for your surface type
- • Cut in edges with a brush before rolling
- • Work in sections to maintain wet edges
- • Clean tools immediately after use
- • Store paint in cool, dry place
