Zinsser 01904A Wolman, WoodLife Coppercoat, Green, 1 Qt

This is my favorite product for preserving wood exposed to weather. It is very effective and worth its price. Basically, it is topically applied pressure treated chemicals, that can make untreated wood resist rot and insects damage. In addition to the chemicals, it seals the wood surface and "plugs" end cuts so it doesn't wick water inside. It has a strong smell and green color, but these vanish over time. When dry, it can be sealed with an oil based primer to lock in the color to paint over with light colors. The can arrived securely taped - no clips, like described in other reviews. I applied it liberally with a 2in chip brush Note that this a "stronger" version than the clear one. The clear one is only for above ground uses, whereas the green product can preserve wood below ground (like posts) when used properly. I only use the green one, even above ground

Looked this product up before I bought it. It was listed as garden friendly and effective. It's very liquid - low viscosity ' seemed to really soak right into the wooden stakes I bought. My "project" was simple wooden stakes so I didn't bother getting too nuts with it. But if you have some wood you really want to last I think I'd do at least two "coats" to whatever's going below ground level and a bit above. And if you live in a wet climate I think I'd treat all the wood.

fantastic stuff, low odor, easy to apply, better coverage than I expected, should do well helping to preserve the wood for my new raised garden bed

We have used this on the decorative railroad ties. Works. Doesn’t last as long as we would like but does make the look nice. Smell is what it is but fades over time. Color is black. Easy to apply.

Local shop wanted twice as $$ for the product. Arrived quickly and safely triple packaged. Had a buck of left over wood that I wanted to use for outdoors so friend recommended this. It stinks - outdoor well ventilation needed and it will smell for a Few days . Give it time to fully dry for Sure. It stretched farther than I thought it Would ( wood)! So I only used one can not 2.

So far so good. Easy to apply. Very low viscosity so it goes on like water. In the attached picture, I did the edges first and then went back to start at the top. You can see the different color where it was applied, but that was while It was wet. Looking forward to my ramp, lasting for years and years.

This stuff is worth having, I like to coat the bottoms of posts, then paint them before I set them in the ground even on pressure treated ones. It keeps the bugs and wood-rot fungus away for years. I think it works very well.

Strong smell, definitely does its job.
