Answer This Question

A:  Thanks for reaching out. Wolman CopperCoat Green Wood Preservative can only be applied to bare wood, it cannot be applied to wood that has been primed. - Rust-Oleum Product Support 6

    A:  It’s made to go directly on the wood.  I believe it wouldn’t do anything on top of primer.  

    by|Oct 18, 2022

      A:  Yeah you can however if you don’t treat the hollow section on the inside you’re not really going to get true weatherproofing otherwise it can pour out from the inside. Copper coating is basically the same treatment that you would put on pressure treated lumber however in the situation it’s not fully pressure-treated it’s only pressure-treated from the exterior but not from the interior so you’re taking a big risk doing this it would make more sense to buy a new pool but for argument sake yeah go ahead and treat it it’ll definitely be better than having on treated lumber on the exterior

        Q:After wood is treated with top coat can it be painted after it dries?

        Answer This Question

        A:  Happy to help, Mary! If applying an oil-based primer, paint or stain over Rust-Oleum Wolman CopperCoat Wood Preservative, we recommend allowing it to dry for at least 24 hours. If wanting to use a water-based topcoat, you will need to wait at least 30 days to ensure full adhesion. - Rust-Oleum Product Support 3

          Q:I?m thinking about applying this on the old one by eight siding on the exterior and then putting Tyvek over that and installing new siding over that. Does this product have a strong smell and if so will it leech back into the house.

              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!

                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.

                Went on well, better coverage than I expected. Now we will see how long the posts last in the ground.
