Tips & Advice
-
1. Preparing the SurfacesIdentify 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.

2. After useReseal can after use. Remove as much product as possible from application equipment before cleaning. For best results use Polycell Brush Cleaner.
