[Music Playing] We previously clean this wood port with some oxygen bleach solution. If you remember we scrubbed it then we rinsed it off and then I let it dry for a couple of days and now it is time to seal it. Well, there is a great news about wood sealers for decks and outdoor wood structures. There is a brand new synthetic resin epoxy fortified sealer and that is the key the epoxy. This particular sealer is basically guaranteed to last two to three times longer than any other sealer that you have previously used. A lot of traditional deck sealers contain natural oils and those things are food for algae and mildew that is why your decks turn black and green. Well, this particular product does not have any that algae food inside of it. It is all synthetic and that epoxy grabs on to the wood fibers and allows it to last much, much longer on your wood Decker porch. In the can, it has this milky chocolaty appearance but once it is dry on the wood it is a semi transparent finished that gives an almost furniture like appearance to the wood. I really like this product a lot and I will tell you what, to get the best results, you need to put on two coats separated by about an hour or two. That is what it says on the label. And make sure you use a nice wide brush just apply it and do not leave any excess that can really cause a problem, do that and you will get results like a professional.
