aadhesives - Substances, like glues, pastes, cements, which cause adhesion, or stickiness. Apply them to clean, dry surfaces.

Drying times can usually be reduced by increasing the temperature. 70° F or higher is generally preferred. Use caution with catalysts and solvents, because most are toxic or hazardous. Softwoods require more clamping time than hardwoods. Because they are so absorbent, endgrain surfaces should receive two applications -- the second only after the first is dry. Clamp joints together whenever possible for increased strength. Applying too much adhesive can weaken a joint in some cases. Follow the directions on the package.

Various types include mucilage, rubber cement, hot glue, epoxy, cyanoacrylic and silicone. Some are available in spray-on forms. Poisonous!Factors determining choice are likely to be: the surfaces to be adhered (porous or nonporous), and needs for strength, toxicity, water resistance, flexibility, temperature range, setting time, and expense. Additionally, some are more acid-free or archival than others, and some are more reversible than others. Velcro ® is also an adhesive.
