Great question! Having worked in cold climates (Minnesota and Wisconsin) for 12 years, here are my top tips:
1. Substrate Temperature: Never spray on surfaces below 40F. Use a temp gun to verify surface temp, not just air temp.
2. Drum Temperature: Keep A and B components at 70-80F. Electric drum heaters and a well-insulated trailer are essential.
3. Cold Weather Formulas: Ask your distributor about winter-grade products with adjusted reactivity.
4. Dew Point Check: Ensure substrate temp is at least 5 degrees above dew point to prevent adhesion failure.
5. Thinner Lifts: In very cold conditions, apply in passes no thicker than 1 inch to prevent thermal runaway.
Hope this helps!
