The winter months in North America are often problematic for gluing applications.
Problems generally arise as a result of cold, dry weather.
Poor glue lines can occur when the temperature falls below the adhesive's specific minimum use temperature. Also during the winter, dry conditions in a shop can cause open joints. This appears as a chalky substance and will have little or no strength. Keep in mind that the adhesive, the ambient temperature, the gluing equipment and the material to be glued must be kept above the minimum use temperature in order to avoid chalking. Because of the insulating quality of wood, the core of a stack of lumber can remain at very cold temperatures even after being inside for 2-3 weeks.
