Rosewood and Cocobolo and Waterlox Original Tung oil finishes.

There are several species of Rosewood found throughout the world and used in various woodworking projects. Because each species is indigenous to different areas of the world, the different climates (soil, humidity, precipitation, etc.) determine their wood grain, color, oil content, density, etc.

What is common to all species of Rosewood is that they are very dense (hard) and contain very high percentages of natural wood oils. These attributes can make Rosewood very difficult to finish and many clear wood finishes will not adhere and/or dry when applied to them.

Waterlox Original Tung oil finishes are compatible with all species of Rosewood other than Cocobolo. Cocobolo is a tropical Rosewood species which is indigenous to Mexico and Central America. The oil content is extremely high and is therefore a difficult wood to finish due to drying and curing challenges.

To successfully finish Cocobolo, apply 2 thin coats of dewaxed shellac directly to the bare wood before starting your project, following the manufactures directions for application. When the shellac has dried, it will seal in the natural wood oils allowing for a topcoat with any of our Waterlox Original Tung oil finishes. Sanding of the shellac is not necessary before applying the Waterlox; when finished you will still have the beauty and look of a Tung Oil finish.

To test adhesion and dry on other species of Rosewood, apply a coat of our Waterlox Original Sealer/Finish and allow it to dry for 24 hours with proper ventilation. Check the film dry by placing a piece of facial tissue or tissue paper on the surface, press down with your finger or thumb and hold for a few seconds, release and pull the tissue off. The tissue should not stick to the test area of the wood; if it does, an additional 24 hours dry time may be required before the finish is properly cured or you may have use 2 coats of shellac as a sealer prior to finishing with Waterlox Original Tung oil finishes.
