Products
All timber products should be treated in their final shape and form. Any surface exposed by drilling or cutting must be re-treated with a suitable remedial preservative.
Resealing is a requirement of the guarantee. Rip sawing, thicknessing and planing are not permitted unless the timber is subsequently re-treated to the original specification. Use fasteners and other hardware which are in compliance with building codes for the intended use.
See Koppers Performance Chemicals Resealing Technical Data Sheet (TDS) for more information.
