Glad to lend a hand. Rust-Oleum Varathane Wood Hardener can be used along with the Rust-Oleum Varathane Wood Conditioner and Varathane Wood Stain. Since the wood species can affect the final color and finish, we do recommend applying to a test area first to ensure it is the color you are looking for. - Rust-Oleum Product Support 5
Thank you for reaching out, Fanny. Rust-Oleum Varathane Wood Hardener is not recommended for use on surfaces with direct food contact, or for areas submerged in water or soil. - Rust-Oleum Product Support 4
Hi John, thank you for reaching out! Our Varathane Wood Hardener is designed to penetrate porous wood fibers that have been damaged by rot or decay. A softer wood may allow the hardener to penetrate the surface a bit, but this treatment would not make the entire board more dense for furniture making. - Rust-Oleum Product Support 2
Charles, I always let the wood dry as much as possible. I have not tried it on soaking wet wood, but when I used it on the tops of my fence posts, I can only assume they were not totally dry. Hope that helps!
They are listed on the label.
Good question, Rebecca. Rust-Oleum Varathane Wood Hardener is designed to penetrate into the wood to prevent rot and decay. It is not a film-forming product and therefore would not be a suitable substitute under glaze. - Rust-Oleum Product Support 5
Had no conditions, with temp at 40.
Hi Jeff, the shelf life of our Varathane Wood Hardener is 5 years from the date of manufacture. We recommend storing the can with the lid tightly sealed to ensure it remains usable for this time period. - Rust-Oleum Product Support 2
No, I used it to strengthen the edge of a door frame.
