Can Titebond Wood Glues be used for projects using teak, cedar or redwood?
Because a surface layer of oil or tannic acid tends to build up on these species, they can present a problem. For either type of wood, planing, jointing, or sanding shortly before bonding will remove the contaminating layer, and allow successful bonding. Otherwise, the surface being bonded will need to be wiped with acetone to remove the layer. Acetone dries quickly, and allows bonding almost immediately after the surfaces have been wiped.
