Application Advice

Ensure surfaces are clean and free from grease, dust and loose material. Lightly dampen one surface before application to activate the polyurethane curing process. Apply sparingly, as the adhesive expands while curing. Clamp components securely until fully cured and remove excess uncured adhesive immediately.
