Hi! I am Scott Paul, a leading exterior restoration contractor and business owner with over 30 years of experience in exterior wood staining and restoration. My simple deck stain facts and tips are based on my history as a wood restoration contractor. See here for more info about me.
- Both water-based and oil-based deck stains can be ruined if exposed to freezing temperatures during storage.
- Signs your deck stain has gone bad include excessive thickening, jelling or clumping, and skinning on the surface.
- Garages and sheds are risky storage locations in winter because temperatures can easily drop below 32°F.
- Always seal the lid completely before storing deck stain to prevent evaporation and premature product degradation.
- Store leftover deck stain in a temperature-controlled room to protect it from freezing and extend its usable shelf life.
- Keep stored deck stain away from heat sources like furnaces and water heaters, even in climate-controlled spaces.
Question: Will a Deck Stain Freeze in Winter?
My Pro Advice on Deck Stain Storage:
Yes. It does not matter if it is water-based or oil-based. If you leave your deck stain in a garage or shed where temperatures can fall below freezing, there is a very good chance it will be ruined. Signs that your deck stain has gone bad are excessive thickening, jelling/clumping of the deck stain, or skinning on the top portion.
When storing your stain, make sure to 100% close the lid or top so there is no evaporation. Store the excess stain in a temperature-controlled room but away from heat sources such as furnaces or water heaters.
