Q:Is this product safe to use in a garden to protect 4x4 wood post ?
by|Feb 28, 2021
4 Answers
Answer This Question

A:  as long as not consumed by anything you intend to eat.

by|Mar 2, 2021

A:  No. I chose not to use copper anywhere food will be consumed.

by|Mar 2, 2021

A:  The label recommends not using near vegetable gardens or in areas of potable water. So as long as you are not consuming water or plants that may be affected by rain water runoff and you use the appropriate precautions when applying like recommended on the label it should be safe. It is considered dangerous to contact with the eyes and skin thus I was very careful in the application process.

    A:  Thanks for reaching out to us, JJ! We would actually not suggest use of the Rust-Oleum Wolman CopperCoat Green Wood Preservative for this application due to the chemicals that are in the product. This would not be a good application around food, and we hope this helps clarify your question. - Rust-Oleum Product Support 1

      Q:can this be used in crawl space wood beams?

      Answer This Question

      A:  I don’t see why you couldn’t, but you should only use it on wood that is exposed to weather.

      by|Feb 23, 2021

      A:  If it is pretty smell proof between the two it should be fine.

      by|Mar 4, 2021

      A:  Don’t know why that would be necessary. The liquid is thin/ watery and spatters a bit with vigorous brush strokes, and in a shallow crawl space that might be pretty messy. If you have high humidity in your crawl space, a vapor barrier on the dirt and/or a dehumidifier would be better for preventing mildew, and unless you have direct contact with wood on dirt, rot should not be a problem. I used mine to treat the cut ends of 4x4 support posts and also the 2x lumber on stringers and treads and handrails of outdoor entry stairs. I added a coat of the treatment to the new uncut pressure treated lumber (and put 2 coats on the cut ends) after letting the new PT wood dry for a week or two after purchase, then let that dry for a day and painted with oil based primer, followed by another day of drying, and then used exterior latex paint after assembly. I wanted extra protection for the 4x4s especially, after previously having a rotting problem with PT 4x4 fence posts embedded in concrete, which despite having a 20 year ground contact rating, lasted only a few years. On the stairs project I used anchor bolts in concrete footings and galvanized brackets to attach the posts, instead of embedding them in concrete. After 4 years they still look great, no peeling (which is why I allowed so much drying time between coats), and I will probably repaint next year just to keep them looking good.

      A:  I would say it should be an ideal material for adding additional protection to your homes substructure though I am not a builder. I would use it for that myself if I had crawl spaces with beams. And now that I have found this product I anticipate using it on more outdoor structures and home wood projects.

          A:  Thank you for reaching out! We do not recommend using our Wolman Woodlife CopperCoat to treat wood that will be used where vegetables or fruit are grown. - Rust-Oleum Product Support 2

            A:  Generally this is toxic to plants. Do not splash it on plants. It's great stuff for wood, but be sure to use it outside--the fumes will make you sick.

              Q:I am cutting my own timber.
              by|Jan 2, 2021
              5 Answers
              Answer This Question

              A:  Yes as long as it is well dried, so the wood fibers will absorb it better. I let the treatment dry at least a day or two and followed with oil based paint (or oil based primer followed by latex paint). The oil based seemed to adhere better to the treatment than direct latex application (as both use mineral spirits for thinning/cleaning brushes) but latex would work as long as the treatment was thoroughly dried before painting with latex.

              by|Feb 24, 2021

              A:  Yes, It’s designed for “green” wood. From my experience, it needs to dry out for a number of weeks in order for anything to stick to it.

              by|Jan 3, 2021

              A:  I doubt it will soak in as well as on dry lumber. Yes it can be primed with an oil primer and then painted

              by|Jan 4, 2021

              A:  I’ve only used it on dry lumber. It needs to soak into the wood so wet timber probably won’t get much penetration. Once it’s had a day or two to completely dry I’ve been able to paint over it using dark latex colors. You might have some color bleed through with a light color. Don’t use it inside - even painted it could have an odor.

              by|Jan 8, 2021

              A:  Good question, Baker! To apply the Rust-Oleum Wolman Coppercoat to new wood, you'll need to check for the presence of surface barriers such as paraffin wax (pressure-treated wood) or mill glaze (Cedar, Redwood, etc.) by performing a Splash Test by splashing a small amount of water on the wood. If the water beads up or soaks in very slowly, use the Rust-Oleum Wolman Deck & Fence Brightener to clean the surface, then conduct Splash Test again before applying this product. This product can be painted or stained. https://www.homedepot.com/p/Wolman-1-gal-Deck-and-Fence-Brightener-Case-of-4-16116/204069612?NCNI-5 - Rust-Oleum Product Support 5

                  Q:Some reviewers say you must use double-dipped galvanized or stainless steel screws. I've been using polymer-coated deck screws. Will these be affected by the treatment? I usually let the wood dry for a week or two after treating and before assembling/screwing.

                    A:  It took a few weeks on my outside shed. Actually, the strong smell lingered for about a month, but finally dissipated completely after a few months. Strong and toxic smelling.

                    A:  Glad to help out, Harry. It is difficult to say how long the Rust-Oleum Wolman Woodlife CopperCoat will take for the smell to dissipate as that can depend on the conditions and one's sense of smell. Keep in mind that this product is suitable for exterior use only. - Rust-Oleum Product Support 5

                      Answer This Question

                      A:  I will try to answer your question. The cabin I treated needs a recoat. About every ten years would be a good rule of thumb. One coat was sufficient. The product was flooded on the logs with a pump sprayer. The product advises against using a pump sprayer. The product will soak in and stain the wood green. The stench of the product will last years. Dries quickly in low humidity. The product doesn’t act like a paint but more like a penetrating stain. 5gal barely coated the exterior walls on an 20’x20’ cabin. Seems to work! Be sure, if spraying the product to wear PPE !!! This stuff is NASTY!

                      by|Oct 27, 2020

                      A:  Thank you for reaching out, Kim! The Rust-Oleum Wolman Woodlife Coppercoat Wood Preservative will last years. A recoat may never be needed depending on the application; however, you can do a splash test over the surface to see if water still beads up. If it does, it's still protecting. If a second coat is desired, we suggest waiting one hour. We hope this helps! - Rust-Oleum Product Support 1

                        Q:I have non-treated rough cut pine wood on a barn that has already weatherized (turned grayish). The bottom of the barn wood does not touch the ground (2" above it). Should I power wash to remove gray? Could I spray paint this on the pine wood? What color would the coppercoat be in about a year? Will the chemicals in the pain ruin any parts inside my paint sprayer (easy clean sprayer)?? Thanks!

                        A:  I don’t see a needTo Power wash the wood unless it’s very dirty. You can also spray it on, it’s waterbase and shouldn’t harm any sprayer parts. It goes on a blue-green tint which will fade over time in the weather.

                        A:  It may penetrate better if the surface is power washed first. This is a coating that will work best if able to soak in. I wouldn't probably spray this on without adequate personal protective gear it is extremely smelly and probably harmful chemicals and is probably very liquid like, not nearly as thick as paint.

                          A:  Glad you asked! Rust-Oleum Wolman Woodlife Copper Coat can be applied to pine wood. This product will have a natural green color, but can be painted over if desired. This product can be applied with a brush, roller, or pump-style sprayer. We don't recommend using this in an air sprayer. The surface must be dry and free of any colored paints, stains, varnishes or built-up, clear finishes, as well as ground-in-dirt, grayed surface fibers and tannin, algae, or mildew stains. You can use the Rust-Oleum Wolman Deck & Fence Brightener to remove the old, gray finish and surface contaminants, then conduct Splash Test before applying the CopperCoat. https://www.homedepot.com/p/Wolman-1-gal-Deck-and-Fence-Brightener-Case-of-4-16116/204069612 - Rust-Oleum Product Support 5
