Thank you for the review!
We urge everyone to check the recommended spread rate for this product on their substrate and then apply the required two flood-coats at those recommended rates.
“Product easy to mix and apply, but even after multiple (2, initial, plus one additional after 6 months) applications, the ground contact rated pressure treated deck does not appear to be quite what I would consider waterproof. But the wood looks great, the natural color is excellent, and I just bought another 5 gallon concentrate to continue applications annually, if not more frequently. This is certainly better than other products purporting to protect exterior wood surfaces.”
Thank you for your purchase and review of our Wood Sealer penetrating water repellent!
Our product is designed to remain 100% vapor permeable to allow for the evaporation of moisture within the surface.
On horizontal surfaces, this permeability will allow for roughly 1.5% of pooling surface moisture to be pushed through the product after approximately 15-20 minutes.
As a result, you may experience a slight degree of surface darkening after this period of time.
Thanks again!
