Exterior project planning
- Air temperature
- 15°C to 35°C
- Surface temperature
- 10°C to 35°C
Air must be 15–35°C; wood surface and product must be 10–35°C. Wood moisture must be below 18%. Do not coat within 3°C of the dew point, in wet weather, or in direct sunlight. Allow at least 24 hours between coats and follow the specified coating system. A fixed rain-free interval is not stated. The Canadian manufacturer page currently links this North American sheet even though its heading says US.
Check the air, the actual surface, overnight conditions and the full drying or curing period. The current product label takes precedence.
