Question: Can I use this product on Teak wood?
Document: I built a large chicken coop over a year ago and used this product to treat the wood. Everything has held up amazingly and I love the patina that it applies to the wood (over a course of months). I still have plenty left over form that build and I will be using it again on any other outdoor wood projects.
Read everything about this product before purchasing. Finally got some decent weather to mix and apply to a cedar cold frame I have been storing to keep dry until I could apply. Mixed up in 4.5 US gallons and applied and set in sun to dry. Within hours the wood had grayed. Remains to be seen how much decay resistance this will provide since that is what it will take to determine effectiveness of this wood item in the weather and with dirt and water exposure.
We bought this product to age and preserve a new hemlock barn and fence. It works within minutes changing the color to a beautiful silvery brown. It is safe for you, your pets and the environment. It's easily applied with a sprayer and supposedly NEVER needs anything else. It's copper based so your hands smell like pennies for a few days. Overall, worth the money, easy to apply, and produces wonderful results.
I was excited to find a wood preservative that did not require me to suit up in a Hazmat suit in order to apply it. Easy to mix, easy to apply, easy to clean up, not toxic to breath, and it does make the treated wood shed water. Everything that Valhalla says about it is true.
I was a little skeptical of the claims of the company but I decided to give it a try. I used mine on Rough Sawn Western Red Cedar, within one day the wood had changed to a weathered brown, which was the look I was after. I am still a little skeptical of the wood sealing properties but time will tell!
It definitely didn't go as far as we thought it would and ended up buying just under 2x what I had planned. I would recommend planning for 50% more than you estimate based on the 500sq.ft. coverage for 5 gallons if you go with the dipping route. It doesn't soak in extremely fast into the wood (even rough-sawn) either so I think that dipping it is definitely the way to go if you are doing new work.
I applied this wood treatment to 6 rocking chairs 2 to 3 years ago. These chairs remained outside. The chairs are simply falling apart. I find out when someone sat in the chair and fell through it. I loved the gray color I got after treating them but the &#34;lifetime&#34; protection is not correct unless 3 years is considered a life time. This treatment did not protect from water and sun. Very disappointed.
I made a better homemade stain that gave a nicer result, deeper color, etc. by dissolving steel wool in white vinegar. Cost me pennies.
We specify Valhalla LifeTime wood preservative for exterior cedar siding and trim when we want an aged patina that looks natural. The preservative quality is an added bonus. Recently used on a personal project.
I'm an architect/contractor and used this for the first time on a project recently. We installed rough-sawn ponderosa pine siding that we milled from trees on our site in reverse board & batt. The homeowners wanted a zero-maintenance finish on the house. The siding looks amazing and has been changing colors over the course of the last 6 months. (I'll attach some photos into the item to share).
