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.
Never warm adhesive above 110 degrees f. The activator may be damaged.
