Universal Tung Oil Sealer Advantages

If you have used Waterlox products in the past, you will most likely remember using our Original and Marine Sealer products. Waterlox has since developed a new product aimed at simplifying and speeding up the application process. This product is called Universal Tung Oil Sealer (UTOS). It still allows for excellent protection, durability and appearance that Waterlox products are known for, along with some excellent advantages.

Very Low VOC

The UTOS is less than 100 g/L VOC making a truly low VOC product. Solvent odor is essentially non-existent. There is still solvent in the formulation; therefore, proper ventilation, proper storage, disposal and care should be used.

Simplified Process

With the introduction of the UTOS, the finishing system formula has become much simpler. For all projects and across all of our film-forming finish families, the directions are one coat of UTOS followed by two coats1 of your desired finish family and gloss level. See the Find Your Finishing System tool to help select the right products for your project.

Shortens Project Time

The UTOS is very high in solids (>80%), so it will fill up the wood faster. You'll get more done in fewer steps. It will still soak into the wood and dry hard, so you will not get a thick, plastic-like film, but instead a solid base with the same excellent, rich, Tung oil color that our Original products are known for. The UTOS will dry in as little as 8 hours (overnight is recommended) and seals and protects down into the wood fibers.

Smoother Final Finish

By buffing or rubbing in the UTOS, you saturate the wood while also knocking down bumps or nibs that may result from sanding. Also, because the UTOS is in the surface of the wood, it will not trap dust or other defects like film-forming finishes. Cleanliness before application of UTOS is less of an issue and sanding is not required after the UTOS is applied, which also keeps dust to a minimum.

Can Still Be Tinted

Many people enjoy the ease of tinting the traditional sealer products. This can still be done with the UTOS. Up to a 50/50 blend of oil based stains can be mixed with the UTOS to create custom colors. Always test first and see our Stain and Waterlox guide for more information.

Options

The inclusion of UTOS into our system is different than our process has traditionally been. If you would like to stick to traditional methods, see our Original Sealer/Finish and Marine Sealer FAQ.

  1. Multiple products are required to complete the project. If you preferred a semi-gloss finish, one could be achieved with multiple coats of the Original Sealer/Finish Medium Sheen (TB 5284). For the Marine products or anything other than a semi-gloss finish, multiple products were still required.
  2. The UTOS requires a different application method. Our Original products are typically applied with a brush or lambswool pad. The UTOS should be buffed, rubbed or troweled on and wiped off. This is usually easily done with the right equipment, but that may not be something that is easy to acquire.

1 Three coats can be used on extremely soft woods like fir, pine, etc. If the wood still looks starved after two coats a third is recommended.
