Properly Prepare the Surface

Proper preparation of exterior wood surfaces is essential to ensure the effective application of One TIME and to ultimately achieve a desirable and enduring finish. Removing past applications of stains, sealers, and coatings, as well as dirt, grime, and contaminants, will ensure that One TIME Stain and sealer penetrates deep into the wood for curing.

If a new wood surface is being sealed, we recommend cleaning off any dirt, grime, and contaminants before applying One TIME. Any dirt or stains not removed will be permanently sealed into the wood.

To remove most other sealers, coatings, deck stains, or other treatments previously applied to your wood surface, One TIME Stain and Sealer Remover is the ideal solution. One TIME Stain and Sealer Remover will remove both water and oil based stains and sealers.

One gallon of One TIME Stain and Sealer Remover will cover approximately 150 – 200 square feet.

Caution: Wear protection for skin and eyes when using One TIME Stain and Sealer Remover; the product is corrosive and will cause burns.

Smooth Cedar

Mill glaze on smooth cedar wood will restrict One TIME from working properly. ALL mill glaze must be removed before applying One TIME.

Sanding the wood and following up using a mill glaze remover may work (We suggest using One TIME Stain and Sealer Remover to remove mill glaze). Test a small area before applying the One TIME.


Avoid contact with the liquid or spray mist- wear protective clothing when applying this material. Chemical resistant coveralls, chemical goggles, and chemical resistant gloves may cause a rash or in rare instances second-degree burns.
