  • Our traditional formulation is product number TB 3809.
  • Formulated as a traditional exterior penetrating Tung oil sealer/primer.
  • Penetrates and waterproofs when used as the sealer/primer coat(s) in conjunction with Waterlox Original Marine Finish.
  • Like all of our Tung oil finishes, 90% of the resin portion of the formula is from renewable, natural resources.
  • For exterior projects, when used as a sealer only, apply 2 coats to prime/seal, followed by 2 coats of Marine Finish.
  • Excellent for use as a primer, tie-coat or paint additive to improve adhesion.
  • Exceptional adhesion to oily, dense, exotic woods like teak, rosewood and ipe.
  • Waterlox Original Sealer/Finish (TB 5284) can be used interchangeably with Waterlox Original Marine Sealer (TB 3809).
  • Coverage. One gallon covers 500 square feet per coat. One quart covers 125 square feet per coat. The number of coats depends upon the porosity of the wood. No thinning necessary.
  • Dry time minimum of 24 hours between coats. Poor ventilation, high humidity or cool temperatures may increase dry times.
