System information

Identify the full extent of any decay, by probing the wood with a sharp instrument. Cut out all badly decayed and very soft wood. Remove paint, varnish, dirt or loose material from the area for repair and immediately around it for about 25-50mm (1- 2 inches). If wood is wet, allow it to dry thoroughly before applying the wood hardener.

Apply liberally by brush to the repair area and immediately around it. Apply 2-3 coats, allowing each to soak in before the next coat is applied. Do not allow previous coat to dry fully before the next is applied.
