We applied this on the backside (southwesterly exterior wall) of our cedar bat and board sided house back in spring 2009. Our cedar had been painted once so we used a pressure washer to strip the paint and then after it dried for a day we applied one coat of the BEHR #501 with 4" brushes. The next day we went to look at it and it appeared wet, but upon inspection, that is just how it looks. After 4 years, it still looks the same wet look as it did that first day after, with no graying or other fade as far as I can tell. We have since applied it to our 1405 sq ft home, and it took less than 5 gallons.I highly recommend this product, and all our guests who see it say the same thing- "Is that stain still wet?". Great product, great coverage, be careful not to overlap when you take a break and start back, a second coat makes it noticeably darker. Highly recommend that you pressure wash away any graying of your wood before applying, if you don't, it will be very dark. Fresh wood turns a beautiful reddish-gold color when this cedar naturaltone #501 is applied.
