Green Products Co. 30001 Copper Green Wood Preservative, 1-Gallon

This stuff really works, for years. Treated some 2x10s on a flatbed trailer that’s left outside in north west Washington. 20 years later, no rot. ‘Nuf said.

Let's deal with the biggest down side first. All the timbers in the coal cellar of my grandparents' house, built in 1875, were treated with this stuff, and the odor never dissipated. My father built a tool shed in 1958, and treated it with the same stuff, and, again, the odor was still there when I left England in 1977. For me, then, there is a nostalgic connection with my childhood when I use it, but other people may well find the smell intolerable. If that's you, you need to know it's never going to go away!That said, for treating outside lumber, I don't know of anything better. I built a 20' x 40' deck around our spa, and treated all the lumber with 3 coats, using two 1 gallon cans, and still had half a can left when I was done. Slop it on with an appropriately sized paintbrush, and repeat until itns no longer being absorbed. That's how easy it is to apply. MUCH cheaper then buying pressure treated lumber, and cknceivably more durable.I'm betting that if you can still smell the stuff half a century or more later, it's probably still keeping the bugs at bay that long, too.

Definitely works. Strong odor! Got the jobs done!

This product appears to have helped protect the wood it was applied to so far, as I have seen no warping or signs of damage. I applied it to a gate that I made of untreated 2x4s left over from past projects. The gate goes to my deck and I put it up to keep the dogs off the deck (they were chewing on wooden chairs and the deck railing). The dogs will not chew on the gate with this applied to it, probably due to the strong smell. The smell has persisted for over a month through several episodes of rain and snow, and it rubs off onto the dogs when they touch the gate. The odor is annoying enough that my wife has made comments about it, and it is difficult to wash off of my hands after petting the dogs.The product works, even though it smells. To me, the odor is worth it for a functional product. This product is meant for ground level applications where this should not be a concern. I am sure the smell will disappear in time, and I do intend to stain the gate next spring which should also mask the smell.

This soaks into wood as if the wood is a sponge. The wood bubbles as this stuff forces it way into the tiny cracks in the wood. Seems like the wood is totally saturated. The green tint went away after a week or so. And regular stain took OK, although it had to be wiped as the wood was probably saturated with this stuff. One gallon was used to cover about 13 ft2 of 2 inch thick tree trunk (7,18 inch tables). The only negative is the smell. It is a musty smell ( locker room, nasty tennis shoes, moldy basement) that takes a couple months to go away. It doesn't seem bad while you are working with it, but as it dries on the wood it is noticeable. Just keep it away from the house as it cures.

This green wood preservative definitely delays wood decay on landscape timbers. The smell is quite intense. Apply in a ventilated area. The green color quickly fades over a period of two weeks. Based on past use, it remains effective for about 4 years.

Used for outdoor pine frames for firewood. EZ to use; well ventilated area is a must. As are gloves, glasses and a mask.

Used product. Arrived with a taped lead and a broken seal.
