with the start of the cold weather rolling in I have a question that keeps pondering in my mind. When the temp is 20 degrees or colder out and you have to haul a Solid surface top 2hours before you get to the job site and need to do a feild seam how long should you wait before you pull the seam together? Tops our loaded in trailer that sits outside first thing in the morning if that makes some difrerence.

Thanks for some in put.

Cold Adhesive:

Adhesive stored in the fridge or a cold shop, should be allowed to return to room temperature before use. Some adhesive components become thicker at low temperatures and may not mix as well. Thickened material creates higher pressure in the cartridge and tip. Higher pressure will flex the cartridge wall and can throw off mix ratio. If you re-warm adhesive, make sure the cartridge plug is in place. A previously used mixing tip left on the cartridge can allow expanding adhesive to back flow into the activator chamber and result in a plugged cartridge.
To avoid activator damaged, never warm adhesive above 110 degrees f.

Cold Sheet material:

Bonding sheet goods that have been stored below normal room temperature will cause the adhesive to cure slowly in the joint. Fabricating with cold sheet goods may prevent a full cure from developing in areas with lower than optimum activator levels.
Warm room air will cause the adhesive on the surface to cure much faster than the adhesive in the joint where the cold substrate will absorb much of the energy from the chemical reaction. This can cause joints to have low strength. For best results, allow product being joined to reach a room temperature of 60 f before assembly.
