Tenino Copper Naphthenate 17% (2% as Metal) - 1 Gallon - Wood Preservative

Arrived promptly and was well packaged to prevent spillage. I wore a respirator, nitrile gloves, long sleeves, and glasses for protection. I applied two coats with a four inch brush and used half a cup to cover a 16 square foot plank, which will contact the ground. Goes on easily, absorbs well. Colors the wood green, so easy to see where you have applied. Strong odor that diminishes daily. Hoping planks last a decade.

Great product. My husband used this on treated lumber to redo our deck. Many years ago, it was called pinta, I believe. It gives an extra layer of protection on your wood. It is easy to apply and works!

This stuff soaks in good. I char untreated wood with a flamethrower then put this stuff on. The people saying it stinks makes me laugh. I’m a mechanic. This stuff smells like the inside a band-aid tin from the 90’s. Thats it. Just a really strong band aid odor.

This is a good product for treating wood but it needs to be agitated before using and once you pull the seal off the top of the container it will leak all over if you shake it again. Will need to be transferred to another container with a leak proof top

If you are using it on trailer boards, it works great . Will not leach out like a lot of wood preserves do.
