I purchased my house in 2014, which had a sizable deck that needed touch up. I believe the original surface was paint but was pretty well completely worn off aside from the spindles. I went to my local menards, and was suggested cabot deck correct, which would fill any cracks and have a thicker coverage to help alleviate yearly repainting or staining. I applied the product and initially it looked great! After a bit however it began to flake off, to the point of being able to pull pieces off that were 3-5 inches long in almost a paint like sheet!! It has completely peeled up. I did touch up areas on it once, and am now at a loss as of what to do next as that did the same thing. I am completely unsatisfied with this product!! It seems to sit on top of the wood if it can be peeled away in entire sections.
