Good high-concentration preservative. Follow instructions.

Foul-smelling stuff, but what do you expect? Penetrates well. Green color when dried fades to green/brown. Don't know how long it will last, but the strength of the smell is encouraging.Wear gloves and know that splashes will be turquoise for a LONG time, if not forever.

Great product!

Used this on our dock at the lake to help preserve the wood from the moisture. So far, so good. It was recommended by the lumber company where we got the wood, and it seems to be working just fine! So glad we got it. It is very messy to paint on after the fact. If you can treat your wood with it before installation (I know, and extra step, right?), it will be easier to manage.

Initial Use Review: Seems Good

Purchased and used a gallon to provide secondary preventive protection to (a) a new house's 6x6 pressured treated household power pole, (b) the pressured treated plywood backer for the power box, and (c) 168 linear feet of 5/4x6x8' ground contact pressure treated deck boards (ground placement, to help stop unwanted water & dirt erosion).Product is easy to use (I used a 3" foam roller), covering all end cuts and all sides of the lumber (including the deck boards' edges). It does have a distinct odor, though, despite the plastic bottle, ziploc bag, and Amazon box (like another commenter described). The odor lessens over time (for me, it was 3 months of waiting between order and use), and I could barely smell it during application.It soaks into wood well, even "big box store, too wet, lumber". However, for those that care about looks... you are applying a copper based protection to the lumber; It will be greener.Prevention of future decay, for my uses, was the goal. We'll see how it does many years from now... when this review likely won't matter. :)

Expensive but worth it? There are few alternatives.

Starting with my one dislike is the price, which despite its eye watering elevation appears to be the 2022 norm for the building supplies industry. That is the major downside to this paint. Having said that I’ll be quiet and go on with the review.This is an easy to apply thin green paint which contains 2% copper, which I believe may be the best (currently not banned in most of the US) residual insect killing fungus suppressing ingredient. Its essentially similar to the green color of treated wood since somebody governmental made manufacturers stop using arsenic as wood treatment. It tends to drip, but can be brushed, rolled or used to soak wood, and lasts a long time once it is dry. It smells of naptha, but its use is outdoors only. My intended use is for treating some 6x6 wood I need to make the foundation of a shed. (The reader is warned to not look at store prices of 6x6 treated lumber if they have any sort of condition which might make them prone to fits of outrage. If anything its worse than paint prices.)

Very good stuff, been using it for a few years now.

Meant to get the 19% but 17% is good too. I mix it with deck stain, diesel fuel and motor oil. Works great. No more rotten decks. I am getting too old to be building decks over and over.

How To Prepare Pressure-Treated Wood After Shaping

Pressure - Treated, (Wolmanized, or whatever) involves stowing fresh lumber in a pressure cooker tank and letting it soak in vaporous and liquid material that will be absorbed. But it only gets absorbed on the shell, not in the innards. So, if your project involves drilling, cutting, sanding, scraping or otherwise removing material from the wood it needs to be re-treated as a prophylaxis against an early demise.Using this particular blend of chemical requires a full understanding of what's being touched and distributed, and a full understanding of how to use it and where to use it and what Personal Protective Equipment is recommended. This means downloading the full literature packet from the manufacturer's website and reading it before opening the jug. My project used 36 short boards and three long boards.There were 96 cuts and 216 drilled holes before assembly. I filled an old deep-dish cake pan about 1/3rd the way with the Naphthenate and brushed the cuts and used a 30mL plastic pipette to flood the drilledholes. A turkey baster would work, but it would waste chemical. A hypodermic syringe would work but they are traditionally a pain-in-tuchas to just get 10mL out of, to squirt down a hole. If I had to do any more, I would switch to a 1.5-inch diameter rubber ear syringe bulb because I could keep it filled and use the narrow tip to aim the drip into the drilled holes. Now my workshop area smells like Preservative as I let the chemicals seep into the wood before assembly, but I'd rather smell Copper Naphthenate than smell mushrooms as the wood rots. Once the stain goes on and once the topcoat of Spar Varnish goes on with the beach sand filler no one will smell any preservative. This product is truly the best for the serious fabricator.
