Substance should be prepared correctly; apply adhesive to one face only; do not overapply adhesive; and stretch out with a roller or brush. The surface should be dry, smooth, clean, sound, and free of dust, grease, wax, polish, and any other contaminants that may affect good adhesion. Let the adhesive surface become tacky (15-30 min), then press the surfaces together firmly by press depending on temperature and humidity. Before removing clamps, allow a further 1-2 days before placing stress on the joined surface; material curing should take place in the shade. Ensure no inherent dampness. Ambient temperature must exceed 10 degrees Celsius and ideally be less than 30 degrees Celsius.
