Cedar Wash™- Ready-to-Use Cleaner for Redwoods, Western Red Cedar, Walnut and Mahogany
The most important step of finishing wood whether it is a log wall, a piece of log siding or a piece of wood furniture is the surface preparation prior to applying a finish system to the wood surface. The reason this topic is so important is that this step or process has an impact on the longevity and durability of the system…
Cedar Wash is designed to remove surface resin oils and high concentrations of water-soluble wood extractives in addition to dirt, grease, grime, pollen, and surface mold and mildew without harming the wood. Wood extractives are compounds present in bark, softwood and heartwood of a tree that contribute to such properties of wood as color, odor, decay and insect resistance. Consequently, these extractives can also discolor paint and finishes (water soluble extractives) as well as create adhesion issues (oil soluble extractives) for many coating types. All wood species contain wood extractives; however, there are a handful of wood species that are characterized as extractive rich woods. This group includes Redwood, Western Red Cedar, Walnut and Mahogany. The second group of wood species that also contains higher levels of wood extractives but not as high as the extractive rich woods include Southern Pine, Douglas Fir, Spruce and Cypress.

“Hi Kevin, This is wintertime view of the front (north) of our home.
We applied Perma-Chink Products to the south side last October.

We tested the existing finish before deciding how much work to do.

This is the nearly completed south side.

Very satisfying to caulk and seal the logs and to have a durable finish on them. A worthwhile project, thanks to quality materials from Perma-Chink.
Thanks.”

Almost for 35 years, Perma-Chink Systems has firmly rooted itself as the premier provider of cutting-edge log home sealants, stains, and maintenance products. There are myriad reasons why log home manufacturers, builders, and homeowners around the world count on Perma-Chink Systems, Inc. Today Perma-Chink Systems made another step forward toward the environment by offering a 3-year shelf life for all manufactured products. Longevity, or shelf life, is the length of time that a commodity may be stored without becoming unfit for use. The shelf life of our products is an equally important environmental factor in order to reduce the potential impact of undesired disposal that could result from a short shelf life. To maximize your Perma-Chink Systems’ products shelf life, follow these important storage tips:
- Keep containers sealed and unopened to minimize exposure to oxygen and oxidation of the product.
- Store away from windows and direct sunlight.
- Store away from heaters or forced air vents.
- Store away from exterior walls, if possible.
- Store in a controlled temperature environment (50° – 70°F, 10° – 21°C)
Shelf life of a full unopened container is three years (no contamination from potential airborne contaminants). Product from opened containers should be repackaged into smaller plastic containers sized to be ‘full’ of product.
