Stains & Sealants

Our roots at Heartwood Lumber are in log homes and rustic homes. And over the years, we have developed our expertise to know exactly the best products to use for the preservation of your exterior wood.

We offer three product lines: Perma-chink, Sikkens, and Timberseal.


Perma-chink is the largest log home product manufacturer, and they are based in Knoxville, TN. We have used tens of thousands of gallons of their materials with amazing success. This product is water-based, making in an environmentally friendly solution. Perma-chink makes exterior stains, interior stains, caulking, chinking, and pretty much any other product that might be required to preserve wood.

Perma-chink is the choice of our clients who demand the best. It comes in many colors, but we’ve hand-selected the colors that the majority of our clients prefer to keep in stock.


Timberseal is an oil-based, penetrating finish. Since it penetrates and doesn’t form a film on the wood, maintenance is very simple and low cost. And while Timberseal is our economy product, it is a phenomenal way to preserve wood long term.

Some people enjoy the matte way this product appears, while some people prefer a wood finish that builds to a more lustrous, satin finish. We carry four common colors of the product.

We can also give you tips on how to best prepare your wood so that you are ensured of a product that lasts for many years.


Sikkens is our flagship product that we’ve carried for over 15 years now. We offer three Sikkens products: The first, Sikkens SRD, is a penetrating oil finish similar to Timberseal. It is a budget-friendly alternative for any project.

The second is Sikkens Log and Siding. This is their high-build finish that gives a gorgeous, lustrous finish for people that want a premium look. This product can be used on any vertical application, but is not recommended on decks.

The final Sikkens product we carry is their BL Interior clear coat. This is a clear interior water-based finish that offers a subtle sheen while protecting your interior wood.
