The drying and curing times differ greatly; there space quick-setting epoxies and there room epoxies that take much much longer to dry and also to complete cure. Generally, the much longer an epoxy takes come cure, the stronger it is. Epoxy glues may not be efficient on details woods that have actually a high acid content, however, such together oak, walnut, and cherry.
