Rust-Oleum 1904A Wolman (Wood-life) Copper Coat Preservative-Below Ground, Quart, Green

Rust-Oleum 1904A Wolman (Wood-life) Copper Coat Preservative-Below Ground, Quart, Green

Q: Can any one tell me what percentage is "Copper Naphtehnate"?

Two quotes from the can: "Copper Naphthenate (CAS No. 1338-02-9) ... 9.1%*" "* Equivalent to 1% metallic copper"

Q: Is this product approved for treatment in vegetable greenhouses?

person below is WRONG (or at least, wrong for the reason they give: ) I just got off the phone with rustoleum and point blank asked them: I want to use this on lumber to build a raised bed garden. is this safe? he said absolutely. the copper based ingredient does not leach into soil or into the root system of plants. he said the only thing they recommend against is treating it in wood that woul then be submerged in drinking water, and I would suspect that is just an abundance of caution. but for greenhouses or raised bed gardens, he said there is no concern at all. an answerer to another question posted this helpful pdf that looks like the product insert sheet http://www.homedepot.com/catalog/pdfImages/6c/6c4778d3-b6fe-4468-944b-80c038ab71e7.pdf and in there it also , among the list of uses, says "planters". I know in this day and age of heightened concerns of "pure" and "natural" etc there will be people like the below answerer who will kneejerk react and say "no way, chemicals!1!!1!" but people, come on. I guess, if you want to go all natural, then weave yourself a wicker basket and tend to it weekly. if you want wood that wont rot that you can plant food next to, use this and dont freak out.

Q: What can be used as a dipping container?

Yeah I don’t see why not. Be careful not to drip it all over though because it’s very odorous.

Q: How long does a coat of this last?

This is intended to give cut pressure treated lumber and, I suppose, non-pressure treated lumber, some of the protection of copper compounds used in pressure treating lumber intended for use below ground. It is intended to be buried, as it is in my application, so is not subject to inspection or practical reapplication. I use it to allow PT lumber to reach its life expectancy. My longest experience with the product to date is 5 years and counting. To me it is not so much how long it lasts as that I know untreated lumber in ground contact will be vulnerable to insects and rot.
