- Multi-use capability. If you have planters, gutters, or other exterior surfaces, a versatile product that can seal wounds and protect other outdoor items provides value.
- All-weather performance. In regions with temperature swings, look for products marketed as all-weather or with robust environmental protection.
- Safety and handling. Follow outdoor-use guidelines, spray in well-ventilated areas, and avoid applying in extreme heat or direct sunlight.
- Application frequency. Some wounds may require reapplication as the plant heals; check instructions for recoat timing and cure time.
