This is my 2nd review. We applied the 1st coat of Ready Seal mahogany color to 3 year old sienna brown pressure treated wood deck last summer. The results were outstanding, as per my review then. UT we ran out of time last season, and only got one coat on before camp was closed up for the winter. Then it got 7 months of Ontario winter, snow, ice and cold. We just did our 2nd coat here 2 weeks ago... first weekend in June, 2023. Water was still beading on the wood from last year's application. We followed original instructions... made sure the wood was below 10% humidity. washed the deck with hose water and a light brushing... rinsed and let dry for 3 sunny days. We used a 6" deck stain brush for the deck boards stairs and vertical skirting. Regular paintbrushes for the rails and posts, and tight spots. Took us 4 hours to do an 800 SF deck and all the trimmings. The stain soaked right in, actually better than the 1st coat. As nice as the color was from the first coat in 2022, the 2nd coat has really added another level of depth and richness that is absolutely beautiful. Like rich lustrous deep mahogany velvet. Water beads up like a newly waxed car. The color really is something to see. Again, neighbors and visitors comments are extremely positive. I am thrilled, again. We will now leave it for 2 more years as is, and reevaluate in year 3. I highly recommend this product.
