No, it is not a copper sulfate, it is a Copper Naphthenate

How long until smell disipates?

I brushed it on and let it sit for 48 hours. then I applied 3 coats of paint. It still has a very strong odor. How long until that odor goes away? I'm thinking of replacing it with non treated wood to get rid of the odor
Asked by: Chet
Took several months for ours -- and on a hot day you can still smell it (a year later).

I've built several decks, retaining walls, and such, where there is ground contact and this seems to hold up as well as the original PT lumber (and, btw, we're in the middle of the forest, which is a paradise for every type of wood-damaging pest and rot known to man). The only problem is that smell---if you don't think of the Lynyrd Skynyrd song "That Smell" when using this, you were not alive in the 1970s. And, yes, "that smell" lingers for a long. long time. If you use this in town, within nose-shot of your neighbors, I can guarantee you that they will become your mortal enemy. And "that smell" always seems to give me a headache, no matter how I try to protect myself from it. Anyways, other than "that smell", it's all to the good.

Rated 4 out of 5 by from Useful I buy this wood preservative occasionally for a couple different reasons. Mostly I keep it around on a project using pressure treated lumber to seal whenever I cut the lumber, since the original treating doesn't always penetrate completely through the lumber. I also use this to treat untreated lumber if I don't have PT lumber on hand and don't want to stop the project. It brushes on easily and soaks well into kiln dried or acclimated lumber, though I'd recommend using disposable gloves because this stuff stinks and doesn't wash off well. I also use it to treat untreated lumber that isn't normally stocked (some plywood and larger beams) as well as preventative maintenance for existing lumber. Overall it is very useful but be careful and don't get it into cuts, onto finished surfaces such as concrete, and I'd even recommend using latex gloves when using.

Rated 4 out of 5 by from It works I used this to preserve wood that comes in direct contact with soil. Most pressure treated woods suggest you should not install them in direct contact with the soil. I installed the first batch of wood treated with this over 5 years ago. The area was prime for termites. I deliberately buried some small pieces to see what would happen. What happened was nothing. They look the same now as they did when I buried them. One word of caution, fasteners must be either double dipped galvanized or stainless.

Rated 5 out of 5 by from Buy this big bottle, not the smaller one! Great value and will go much further than the smaller bottle, even if you're covering a smaller board you've cut the end off of. You can always add another coat to the "outside" of your board if you're doing a mud sill. Plus, this bottle is big enough to pour into a bucket and set your board end down in. Once done, simply pour the remainder back into this original container.

Rated 4 out of 5 by from strong odor Applied to landscape timbers 2 weeks ago. Very strong chemical odor and lingering 2 weeks later. I hope it will diminish sooner than later. Did a nice job to freshen their appearance and hopefully extend their life.
