Filling Timber

Timber often becomes damaged, especially outdoors. Timber shrinks and swells with changes in humidity, so fillers must be slightly flexible or further damage can occur. Plasti-Bond Builder is a polyester (two part) filler that bonds strongly, has slight flexibility, and can be drilled and shaped. Tip: For chips in ornate routed timber edges, stretch some glad wrap over the edge, mix some Knead-It Multipurpose and force it into the design over the glad wrap. The set block of Knead-It can then be used to tool the repairs to perfect shape.
