We just applied Ready Seal mahogany stain to the decks of our lakeside cottage in Northern Ontario. The 3 year old decks decks are built from sienna brown pressure treated spruce. They were sun faded and very dry. As advertised, the product is goof proof. Pressure washed deck 48 hrs before application, and sun dried. Application was easy-we used with paint pads, and brushes for small areas and between deck boards.. Used a few rags to wipe a few small puddles and black aluminum spindles. No runs, streaks..nothing. tried 5/8 nap roller, but found it too thick. Deck surface would be easier/neater to do with 3/8 nap roller, IMHO. Regardless, it goes on super easy. Talked to Ready Seal folks on phone re questions and tips. Their advice was spot on. No sanding. A light pressure wash 2 days before applying, and sunny conditions made it a simple process. Deck was completely dry in 48 hours, with water beading on wood surface. Our deck looks like it is ensconsed in rich mahogany velvet. It is truly beautiful. Multiple neighbors have commented on the rich color, and asked for product details. 2nd coat to be applied in summer of 2023. Will do further review then, but right now, our rating is "wow". I highly recommend.
