I bought this product to resurface a 15 year old wooden deck. I think there are a few reviews/answers in the other listings New Techwood that are a bit suspect, but I still give it 4 stars. Overall, the product is beautiful, very dense/heavy and easy to cut and work with. There are several things you MUST KNOW about using this material and I strongly recommend that you watch the manufacturer videos for deck layout and installation. First, you MUST PREDRILL for every screw. If you do not, the dimples will be significant..assuming you can get your screw to pite into the plastic skin. I am pre-drilling with a 1/8 or 9/64 bit and still get dimples. Second, YOU CANNOT place screws closer than 1.5 inches from the ends, even when predrilling. This means that if you are resurfacing a deck, you must hang sister joists wherever there is a butt joint so each end sits on its own board. If you fail to do this, there is a very, very high probability that the board will split. If you are building a new deck, be sure to place double joists where you expect butt joints to land. You also cannot "toenail" screws, especially at the ends, or the board will split. Somebody suggested edge screwing with a Kreg system, but I am certain that these boards fastened in that way will eventually fail. Third, you must make sure each joist in the deck is perfectly level. Regular wooden boards have enough structural stiffness to level uneven joists. This material does not. If a joist is high or low by 3/8 of an inch or more, you really need to level it or the deck will look like a rollercoaster. Fourth, use a 2.5 inch composite deck screw for these boards because, again, they are not rigid enough to require anything longer. Fifth, when cutting this material, the resulting"sawdust' is mostly a fluffy brown snow-like material tha clogs tools and dust collection systems. Be prepared to clean up frequently. Sixth, it is EXTREMELY DIFFICULT to get a consistent screw depth using composite screws because most screws easily cut right through the pre-drilled composite material and there is no natural stop like with traditional deck screws. I am very skilled fastening regular wood and even hanging drywall, but it is impossible to consistently set screw depth with this stuff because the screws don't stop. I even tried using a drywall screw gun with no success (totally useless with star bits in any case...). And lastly, try several types of composite deck screws to test the material with. The first type I used pulled through the thinner fascia boards relatively easily, and some, particularly those that use T-20 torx/star heads cut through the board nicely but strip so easily you wil go through dozens of bits. I used a traditional surface mounted composite deck screw technique to fasten the boards using 2.5 inch composite screws and had to set the clutch on my driver to low so I could more carefully control screw depth. This took FOREVER, but the results were acceptable.
