Any suggestions regards a cheap wood preservative/barn paint?
The do gooders in Albany[NY] have apparently banned the copper naphtylate containing Cuprinol.
I need to coat bare wood on a large leanto[16'x16'x10'].
Someone suggested used motor oil. ....not sure about that.
I'd prefer to spray the coating on with a hand sprayer,versus using a brush or roller.
If I could get copper naphtylate directly,I'd just mix it with a deck sealer.
Frankly I miss creosote-it worked and it was cheap.
One avoids the toxins by wearing level C PPE[rainsuit,boots,gloves,respirator with organic vapor cartridges- same as when spraying pesticides].
Non-detergent motor oil or Hyd. oil works better than Thompson's Water Seal. If you want to really go cheap, I guess you could use used engine oil. Preserves, but can be a bit messy, too. New oil soaks in and doesn't draw dust or dirt like I thought it might. Keeps the new wood color. Brings out the grain a bit. I like it.
I'm not arguing in any way about your post concerning oil on wood, I think it's a great idea. I have nearly ten gallons of used hydraulic oil sitting in my shed from changing oil in my tractor. I have considered spraying it on my lean-to, but I was concerned about its washing off and polluting the soil.
Do you plan on removing this lean-too and growing crops in that spot?
I really wouldn't worry too much about contaminating the soil. If you are careful when applying it there should be little hitting the ground. Also once it's soaked into the wood it's not gonna wash off. Oil and water don't mix.
It was common practice in these parts to spray used motor oil on the dirt floors of most garages to keep down dust. Driveways and roads were treated similarly.
None of the local water supplies that have all been tested show any traces of contamination from these prior actions, so that's why I don't think it would hurt.
I don't know anything about hydraulic oil.
Having a deep emotional conversation with my quilted buddy..........
I haven't had any oil leak onto the ground, but I used a paint roller. Spraying always puts more product into the air, paint, oil or chemicals. I think you'd have about the same risks as Thompson's Water Seal, because it is an oil based product, too.
Well, I wouldn't know naything about this, but if you lived down in oil country...drop by a producing well, crack a valve on the storage tank and get a bit of crude oil. Mix it 1:10 with diesel fuel and one teaspoon/gal of Dawn dishwashing liquid. Apply with a garden sprayer.
