Wolman 1904A WOODLIFE CopperCoat Green Wood Preservative, Quart

Comes out white, turns clear immediately, don’t know how it works but it’s exactly as they say--dries fast, drips are common but no concern, and soapy water cleanup. Fast, economical, and effective, I did a test with a spare piece of lumber, dipped it in Woodlife, dried 24 hours, then SUBMERSED it in a bucket of water, it’s totally waterproofed! Can’t claim for how long, but for the purpose of my test it was good enough for my usage, which was a newly constructed handicap ramp. And at a price of four gallons for a hundred bucks, I’m ecstatic! Be advised though, it’s VERY thin, thinner than water even, definitely wear eye protection for spatter if you’re brushing it. Also, the can says nothing about stirring, but I gave mine a quick shake before opening, simply because you may have a few lumps of white pigment stuck to the inside of the lid if you don’t. In fact it’s usually a good idea to give any stain, paint, or sealer a stir before using.

Awesome product! Much better ingredients than the brand Home Depot sells. I think it has a higher copper content.

Expensive, but it seems to work to prevent premature rotting / deteriorating of wood flooring on a trailer.

We have used this on the decorative railroad ties. Works. Doesn’t last as long as we would like but does make the look nice. Smell is what it is but fades over time. Color is black. Easy to apply.

I recently had to do a forced remodel of a bathroom thanks to an undetected water leak. When I went to pull the walls apart, I found that the original studs had been coated with copper green, brand unknown. Now since there is not a building contractor in the world that goes above and beyond to do anything more than exactly what is required by contract, i'm supposing that the copper napthenate that the original builders painted on was due to local building codes. So, wanting to stay in compliance and build the rooms back exactly as they were in their original state, I ordered the Woodlife Copper Green to coat the new studs. The product is very thin, goes on with a blackish-blue tint, and is best applied with a two-inch brush. It takes some practice with the brush to get the right amount so that you are not flinging it all over the place and wasting product. Once you have mastered applying the correct amount, it quickly soaks into the wood, and is dry within a few hours. However, it is not completely cured for several days. That being said, during the cure, the stuff will turn green. It will also emit quite noxious fumes. It smells exactly like an auto repair shop, just a bit stronger. Have a fan handy and open the windows for several days. I can't speak for the efficacy of this product. Upon inspection of the original studs that were also coated with copper napthenate, they had rot in them as well, just not as badly as the untreated floor. I honestly don't see where this product adds value or protection, because if your floor has rotted out, you may as well replace your walls as well. Even if the studs have not rotted, they have probably been in the house long enough they have become brittle and will split as soon as you rehang your wall board. Best thing is just to root out all of the wood that has been touched by water and replace it. One small container of Copper Green will coat about 16 studs.

Used to treat wooden poles exposed to the soil.

Great product. Easy to apply

Product is fine which is why I ordered it again. Packaging is bad, 1 qt can in box bottom smashed at seam due to improper / lack of paper cushions. In addition to that no safety clips on the 1 qt size paint can, which was surprising. And the final disappointment was this can does not have the plastic pull up reasealable pour spout like the first one I bought. For a toxic product like this that was a GREAT SAFETY AND CONVENIENT FEATURE. Kind of dropped the ball on this one Amazon 👎
