How does Cyanoacrylate adhesive work for gap filling?
Has anyone had experience with cyanoacrylate adhesives for gap filling? I want to know if I can use this type of adhesive to glue small sections of various timbers about 4mm thick to a timber substrate. I need quick and very permanent adhesion without subsequent movement, as the pieces are fitted tightly together forming a geometric pattern? CA could work well for this application providing you don’t need a high degree of water resistance and the pieces won’t be subjected to considerable shock. There are three things to be aware of when using CA. 1. Moisture: If your wood is dry, make sure that humidity is high. Often a heavy breath on the material just before gluing is sufficient. This moisture allows the adhesive to cure properly and will keep it from absorbing water later. It will then be quite waterproof. 2. Acid: Most woods and your skin oils are slightly acidic. CA cures best in an alkaline environment. Dusting the area with baking soda will solve this situation. 3. A tight joint
