Wood windows and doors must be protected on the exterior. That's why Kolbe offers K-Kron II. K-Kron II is the highest quality warranted finish for exterior wood substrates in the industry. Independent testing in extreme conditions has proven it; see the test results below. At Kolbe, we stand behind K-Kron II with a 10-Year Film Integrity Warranty. This warranty is extended directly to the homeowner, and is transferable to subsequent owners.*

Even better – K-Kron II is as beautiful as it is tough. Our new color palette, Environmental Expressions, includes over 30 vibrant colors inspired by nature. Infuse your home with stylish Kiwi windows and doors. Incite curb appeal with bold Butterscotch sash and Slate frames. Or, imagine a custom color and provide a sample to manifest the dream. Rest assured, the colors will stay vibrant due to high-grade automotive pigments in the topcoat.

What's more, K-Kron II is green. The application system meets federal guidelines for emissions. The primer and topcoat contain chemically-inert pigments. And, clean-up does not require special disposal. Learn more about Kolbe's green initiatives.

THREE-STEPS TO APPLYING THE K-KRON II EXTERIOR FINISH SYSTEM

Step 1: Before assembly, wood pieces of the window or door are immersed in a preservative with both an insecticide and a fungicide -- helping the exterior wood surfaces resist decay. This preservative meets standards set by WDMA I.S.4-2000.

Step 2: The windows or doors are assembled. Before installing the glass, two coats of a specially-formulated urethane primer by Akzo Nobel is applied -- helping to seal the wood and provide a bonding surface for the final topcoat. The primer is applied using a controlled-spray process which follows WDMA T.M. 11-2000 guidelines.

Step 3: Finally, a high performance urethane topcoat is applied. An airless, multi-step, controlled-spray system ensures complete, consistent coverage of the exterior wood surfaces. The result? Beautifully protected windows and doors.

The K-Kron II three-step exterior finishing system follows WDMA T.M. 12-2000 guidelines.
