Make sure you stir well. Mine had some serious settling. Review: Easy to apply but read the directions. - Amateur wood worker. teated lumber has issues with standard paints when the wood is new. Did some research that poly or resin were the best paint solution. Rebuilding the deck I built 25 years ago and one of the issues treated joists deteriorated. I determined I wasn't making that mistake 2x and settled on this product. I ordered the brown color. I applied with a brush but product well suited for a sprayer. Product absorbs quickly and you do want to follow with second coat so ensure your job is divided in the 15 minute time slots for second coat. Because these are joists I did not spend more than a light sanding before application. I really like how the brown tint came out on treated lumber and it appears to protect the wood well from moisture. The product is very easy to apply with a brush and goes a long ways in spite of the two coats. I highly recommend this product on treated wood, in my case I think it will do well as the poly really soaks into the wood. I suspect it will hold up very well, but only time will tell. ## Features - WATER-BASED POLYURETHANE WOOD FINISH: Our sealant provides top-notch protection against wear and tear in high traffic areas.
