What Customers Are Saying

Customers overwhelmingly praise this wood sealer for excellent water repellency, long-lasting protection, and ease of application with brushes, rollers, or sprayers. Many report that water beads up effectively, revitalizes old decks and fences, and delivers full coverage in a single coat with quick drying. However, a notable group expresses disappointment with color accuracy, reporting the finish appears much darker and redder than advertised, particularly those expecting a transparent or natural wood appearance. Despite this mismatch, most customers consider the protective performance and user-friendly application worthwhile.

miserably effective deck sealant

This provided excellent water resistance to wood decking, and yes, as the instructions indicated one application, one coat was sufficient

Would Recommend

Easy to work with. I am using this on my scaffold platforms. Highly recommended. Clean up was no problem. Applied to wood without any issues. I wish the can spout was a little longer to facilitate pouring the liquid out. Otherwise, highly recommended.

Watery pink liquid

Would Not Recommend

This product is not the same sealant from previous years. It is a watery pink liquid, not at all like the color of stain pictured on the container. Even when dried, it is still the same shade of pink. No way would it ever be sealing the wood from the elements. So disappointing.

Was easy to apply. Color was as represented

I liked the product. I just decided that I needed to get a little different stain color, which I did. I will be going back today for a second gallon of the product. Debbie Elkan
