Rated 3.0 out of 5.0 by too long cure time for me 7 day cure time not listed on sealer can instructions...after applied looked up manufactures PDF for product online and called company tech to verify before flooring install January 29, 2013
Rated 5.0 out of 5.0 by Used to treat new cedar trim in a moist environment. We needed a sealer with mold and mildew prevention to treat new red cedar window trim in a greenhouse. It is too soon to tell how this product will perform over time, but we chose it after reading the Western Red Cedar Lumber Association's useful guide, "How to Finish Red Cedar" pdf. which stated: "Clear finishes or water-based acrylic, polyurethane or acrylic/polyurethanes are an excellent option for finishing Western Red Cedar at home." Sealer went on smoothly and dried nearly clear so the wood grain still shows through beautifully. September 5, 2013
