The wood treating experts at Kop-Coat have solutions for you. We know from laboratory tests and field experience that the best way to protect exterior wood from decay is to treat it with a water-repellent wood preservative after all machining is completed and before it is primed. Wood windows and doors need protection. Doorframes are especially vulnerable to decay because of their close proximity to the ground. The cost for decay and insect protection is only about $.25 US per set of exterior frames.

The Woodlife family of products also includes Woodlife F-15WT which is the standard millwork preservative with insecticide added.

Woodtreat® Wood Preservatives: This product line has similar active ingredients to the Woodlife solvent based family but contains added ingredients for enhanced paintability.

Both Woodlife and Woodtreat Preservatives are EPA-registered and approved by the Window and Door Manufacturers Association and recognized by the American Wood Preservers Association. They are available in ready to use and concentrated form.

Timbertreat® 15WT Insect Control is an effective insecticide concentrate which controls termites, beetles and other insects. It is dilutable with mineral spirits or water and may be mixed with all Woodlife and Woodtreat Preservatives.

Timbertreat® B is a unique new additive to solvent-based wood preservatives that penetrates deep into wood to protect wherever moisture can reach. Added to Woodlife 111, the Timbertreat B combination provides the most powerful deeply penetrating protection of any known surface applied system.

All of these preservative products are available in 275-gallon totes and 55-gallon drums. Several are offered in tanker quantities.
