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.
