Application
Follow the manufacturer’s directions for application. Urea resin and resorcinol should be applied in a thin coat. Others, such as mastics, hot melt or contact cements are applied in thick beads or layers. Generally, glues are applied in one of two ways. Either to a single surface (single spreading) or to both surfaces (double spreading).
But whether you’re applying a thin or a thick coat . . . to one surface or to both...it is of the utmost importance that the application be even. The most common aliphatic resin or polyvinyl resin glues can be spread with a stick, your finger or a brush. Contact cements and some special veneer glues are best applied with a glue spreader -- a flat piece of metal or plastic with a serrated (or grooved) edge. The deeper the grooves, the thicker the glue coat. Again, follow the manufacturer’s instructions for the best method.
When applying glue to a single surface, press and rub the two pieces together for an even spread, then allow the glue to soak into the adjoining surfaces for a strong bond (See Figure 1.) Continue . . . |
