I stained a new, pressure treated (2x6 material) pine deck last year... I was not happy with the results (poor adherence, peeling and flaking), but to be fair to Defy, I don''t think I waited long enough for the ACQ to dry from the wood. I stained after 3 months, when I should have waited longer. Also, tried to stain in sections, instead of the recommended complete length of board, and ended up with distinct, visible areas of overlap (stopping and starting). Don''t do this! Complete a length of board(s) before you stop. This is a penetrating stain; if you don''t follow the instructions to a T, you will have poor results.
This year I rented a random, orbit floor sander and using 36 grit paper, stripped the entire deck (500 square feet). Last year I used the recommended large brush to apply but found that to be very messy, although pretty quick and easy. This year I donned my knee pads and used a 3 1/2 inch staining paint brush. Much slower but I felt I had really good control of the application. Because I had such poor results last year, this year I only put on one coat, in hopes of minimizing any chances of flaking, plus I felt like trying to get the second coat down in a timely manner was going to be too difficult since I have such a large deck - if you put it down after the first coat dries, you won''t be happy. This year I observed the stain penetrating nicely into the wood, and my application was much more uniform. I could also basically apply a "second coat" by simply back-brushing, as I progressed onto untreated surfaces. I believe the recommended wait of 20 minutes before applying a second coat, could be too long depending on your climate. Where I live should be "within 20 minutes."
This year the staining turned out really well, and the color is awesome (light walnut). My plan is to apply a second coat in late fall/early winter before a threat of freezing. After consulting Defy, I learned that applying additional coats is dependent on the "water test." If you put drops of water on the deck, and they absorb right into the wood, then you can apply another coat. If the water doesn''t absorb, then an additional coat will not penetrate and you''ll have poor results (flaking, poor adherence). This water test should be done on several areas of the deck; not just one spot. If my test results with the water not absorbing right away, then I will wait till next year to apply the second coat (I guess I did a good job of staining, if that happens). My intent of applying a second coat, is to have the deck in a condition, where I won''t have to stain it for a couple of years.
My color turned out great this year, so I have trouble understanding some of the reviews that speak of poor color. Last year, I ordered some sample stains from Defy''s web site, and stained scrap wood, in order to choose the best color. This is a good method to use, if you are unsure about how your type of wood will look with stain. Another good hint is to be careful of the sun. This stain will dry too fast if you apply it in direct sunlight; you want it to penetrate into the wood, not dry on top of it. I have two boards that I''m worried about, because the clouds went away as I was staining, and it seemed they dried a little too fast. Not much I could have done; once you start don''t stop until you complete the entire length of board.
The only thing that remains to be seen, is how durable and long it will last before I have to re-stain.
