    Not what it used to be

    I’ve been using this on a cedar mailbox post, I have put numerous coats on it. Looks great when you first put it on but after three or four days it looks bleached out again.

    Thank you for your review, we apologize you had an issue with the Clear Wood Sealer. Since this is a one coat product, multiple coats should not be applied. The sealer does not build a film, so the product should not have a shine. If you would like to discuss your review further or have any questions, please contact us directly at 1-800-367-6297 or info@cbgbrandreview.com. Sincerely, L.T., Customer Support Specialist

    Quick & easy

    We have a 10 year deck that has only been powerwashed and we decided to add some clear waterproofing. Nice thick viscosity, easy to use, applied it with behr stain pad which worked great. The pad was very useful and easy to run along the spot in between each board. Rain moves in Wednesday morning so fingers crossed 🤞.

    Yes, I recommend this product.
