I built a ceder deck on the side of my house a few years ago I sealed it with a Cabot water proofer wood protector. It didn't hold up to well. I just sanded the whole deck down and am going to reseal it. I am looking for the best product to use! I want something to protect the wood and repel the water, Any suggestions?
Agreed, Penofin is an excellent product. Nothing is going to last several years without maintenance, so plan on re-applying every couple years. It is a penetrating oil, and does a great job. In my opinion, deck "sealers" (Thompsons, Cabot, etc) are a joke.
