      A:  Happy to help, Raff! Yes, Rust-Oleum Wolman Woodlife CopperCoat Wood Preservative does contain Copper Naphthenate. - Rust-Oleum Product Support 3

        A:  copper naphenate

        by|Aug 15, 2023

          A:  There's a SDS Datasheet which you can download directly from Rust-Oleum's web site, just for future reference. Directly from that datasheet: "HAZARDOUS SUBSTANCES Chemical Name CAS-No. Wt.% Range GHS Symbols GHS Statements Copper Naphthenate 1338-02-9 2.5-10 GHS02-GHS07 H226-302 Monoethanolamine 141-43-5 2.5-10 GHS05-GHS06 H302-311-314-332-335" Simply put, yes, it's a water-based solution with a pigment dye, among other things that are there to perserve and assist in storage and application of the wood preservative, otherwise it's copper napthenate. "Monoethanolamine" can be used as an artificial sweetener for natural gas, so I'm assuming as an aromatic, a lubricant, detergent, but in wood preservatives, I believe it may play a double role. It seems to mostly be a lubricant used to allow the copper napthanate to penetrate deeper below the surface of the wood. It may as a secondary action act as a detergent or soap by removing impurities ot duston the surface of the wood. That's simply a guess because the main purpose of this specific wood perservative is to treat cut ends of preserved lumber during the building or assimbling of a structure, like a fence or deck. Also, it would explain why in the directions it states that if you require deeper, or better, penetration of the preservative, you want to soak the cut ends of the wood in the preservative, not use a brush. Another option is to set the cut end of the wood up in the air vertically, whenever possible, or at least set it higher than the other end. Then use a brush to apply the preservative, and gravity will help with penetration. A vertical slanted board should be flipped over every other coat. Just remember to mix or stir between coats to ensure the copper napthanate is equally dispersed in the suspension.

              copper coat 2023
              June 20, 2023. We ordered the 6 pack online and it was shipped to the store for pickup within a few days. We coated 56 agricultural treated posts between 4 and 6 inch diameter. We coated 42 inches on the end going into the ground and 12 H braces since we had plenty of coating. We used gloves and a brush to apply outside. Time will tell, but we figured $100 is a good investment for our fence project.

                Terrible color
                Put on bottom of split rail fence post. I was under impression that it would be a faint color and would fade. It’s been 9 months and still looks terrible. It’s an ugly black against the natural cedar color. Am I supposed to paint the split rail? Ridiculous!

                Thank you for reaching out, Patrick! Rust-Oleum Wolman Woodlife CopperCoat Wood Preservative will impart its color into the wood. The treated surface can be over-coated with oil-based primer, paint, or stain.

                  its about the only worthwhile wood treatment available in Florida its been used for wood preservative Copper naphthenate is an active ingredient used predominantly in industrial and commercial wood preservation for non-pressure (dip/brush/spray) and pressure treatments (vacuum/full cell) to protect against fungal rot, decay, termites and wood-boring insects in unfinished wood and various fabricated wood products.

                  I use Wollman Copper Coat for all of my custom mailboxes. The bottom and first 24” always get a good coating of product before paint. Any time PT wood goes in the ground, cut ends need recoating!

                  Good Instructions for application as well as where the product should not be used (vegetable gardens, fruit shrubs and trees, etc). Too early to tell how effective the product is. Need 5 to 25 years to determine the efficacy of the product.

                  This stuff is potent! The case I received of four one gallon cans came with a convenient pourable spout mounted to the lid. While pouring out of a full can the flimsy bottom of the can "oil canned" causing a belch of the fluid all over my hand. Rinsed with water as directed but my finger tips were numbed for hours and my hand stunk. Wear chemical resistant gloves and eye protection when using this product. I think the bugs and rot spores are going to get a little numb as well if they get close to CopperCoat

                  Great product
                  I was able to use this product to coat/protect the bottom of my fence posts and it worked great. I used the dip method and thought it worked much better than painting it on. Highly recommend but use precaution when handling the product.

                  A longer life for exterior wood.
                  This product is one of the best wood preservatives I have ever used. I highly recommend Woodlife® for all applications where the wood may come in contact with the Earth. Unfortunately, you will have to order online as it is not a stock item and your local Home Depot. Where I want the project to look aged I mix 50/50 Woodlife® and black latex paint. When dry it will provide a weathered gray appearance and greatly extent the life of the wood. I have also done the same using red latex to offer a weathered redwood aspect. Application is easy using a brush, roller, airless spray or dip. Regardless I highly suggest that you use latex or rubber gloves. Cleanup is a breeze using soap and water.

                  Great for fence posts and wood fences.
                  I used to use old fir logs for fence posts untreated for a quick fence but after awhile they rotted at ground level. but I put up a fence around my garden using 7 foot lengths of Doug fir for post and braces and soaked in this stuff they not only look good and rustic but they're still holding up strong even the partly rotted brace. It's good stuff, but the smell stays with you awhile. I'd suggest wearing gloves and coveralls when using it.
