Application must be done sparingly as very little adhesive will create a strong bond. Avoid bleed out of adhesive onto the finished face of the moulding as this will cause damage. Run a thin ribbon of adhesive onto the one mitered surface. Rub the two surfaces together to spread the adhesive, and hold together for approximately 10 to 15 seconds for initial tack / hold to take place. Underpin immediately. Final curing will take hold after approximately 5 minutes.
