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

Very good stuff but is very concentrated and the smell will stick to your nostrils so use a mask or respirator it's strong

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.

Green in color. This stuff works well and is easy to apply. I recommend wearing disposable gloves but the stuff is exactly what you need to preserve and seal wood surfaces exposed to weather and ground.I wouldn’t use it indoors unless it was subflooring. I have used it in the high mountains from 3500 to 8450 foot altitude. Exposed wood to rain sleet and snow. The color will fade a bit but I didn’t get it for color but to preserve and seal the wood surfaces exposed.

Good replacement for WOODLIFE GREEN and costs less. Nice plastic bottle instead of a can.

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.

Copper Green is reasonably priced at 1 gallon. Use safety equipment when applying the product. I used PVC long sleeved gloves, a 3m high performance respirator, and a 3m face shield. Users are correct when they state it has a pungent odor. Try as best as possible to keep off your skin. The smell lingers on your skin for a day or two even after thorough washing. Trust me, you breathe enough of the vapors and you will get dizzy or sick. I was born with asthma and just getting a whiff of this stuff sort of makes me wheeze a little. I needed to use this product up under the eave of my roof. I have a metal roof and somewhere near the end of the valley is a leak. Water gets under the flashing and finds an opening through either a nail or screw hole. Copper green is for exterior use only. I used it in this situation since the area affected is at the eave and not above livable space. The vapors don't intrude the inside of the house.

Same product that I was using a long time ago. Bought it on Amazon because I was having trouble finding it where I live. Great product. Love the speed that it took to receive it. it.

I've been a carpenter for 40 years.Whenever I run into dry rot, I will try it out.The deteriorand I use this. Topical treatment
