I was very pleased with a fence post treatment. I am sorry I forgot the name but it went on very heavy and dry time was 24 - 28 hours. It really wasn't too messy. I used a pour and roll technique with a big floppy roller and a 4" cheap house brush to catch runs and coat the edges. It dried hard not gummy and looked good a very very dark black/brown.

I think I used stuff similar to Bob. I got a gallon of Black Beauty Asphalt Fence Post Paint from Tractor Supply Co. If I recall, it was only about $10/gallon and it went on relatively easy using an old paint brush and roller.

"For exterior use only. Weatherproofs, prevents rot & decay, stops rust, termite repellent, use above & below grade, long lasting."

After drying completely... 3 coats


From that picture, you can tell it penetrates into the grain a bit, and it has a nice heavy duty finished texture to it.

If you decide to go with the Henry's brand, make sure its the 201. I recall a member on here getting a can of different number than the 201, and it remained tacky for a long time (a week or 2)

Many people used and like the Henrys 201 that planovet used.

Ok Thanks.... There is a Tractor Supply Co store right near my friends house where I am going to be doing my build. Did you use more then a gallon for 3 coats? The base of my trailer is going to be 5x9.

Now my next question. Since im widening my HF 4x8 trailer to a 5foot width, my plan is to run 3 2x4's 9 feet long down the length of the trailer and put 4'10" long tongue and groove planks across the width of the trailer and screw them down into the 2x4's which would then be boted to the trailer frame. I want to put the pink foam insulation on the underside of the trailer. Should I tar it, then add the foam then tar it again? Because weight is an issue, my car can only tow a 1000 lbs and Im trying to keep it light so I dont kill my car lol I dont really want to add plywood under it.

thanks!

One gallon is plenty. My trailer is 5x10 and I had plenty left over. I used only one thick coat and it only took about 48 hours to dry. It's been 2 years now and it still looks like the day I laid it down.

Make sure you use gloves and old clothes. That stuff will get everywhere.

...be careful about creating a "water trap" against the floor with the insulation...why not build the floor, bolt it down and lay the insul on top and your mattress on top of that...............

Good Point MadJack... didnt think about that. My plan was on the inside of my trailer I want to take the foam mattress that Im going to use to cut it and stitch the cover so that I can "S" fold it into a couch during the day(well who knows how lazy I will be when Im useing it lol) hmmmm...

Deryk the fence post stuff is called Blackbeauty and is real easy to put on. I just finished rollering it on 30 mins ago with a roller and brush set from HD. The asphalt post stuff was $14 at TSC.

I just ordered some of the Black Beauty Fence Post Asphalt Fence Paint, from Ace Hardware. They have a 5 gallon bucket for $36.99 (they don't have single gallon cans). Tractor Supply Co has a 1 gallon for $13.99, which is all I need, but I have to pick it up at the store, and the nearest store to me is in Leicester, MA which is a little over 30 miles away one way. That 60 mile trip, according to AAA is going to cost me around $30 (around 50 cents/mile for a small sedan), which brings my real cost to right around $44 for a gallon of this stuff. Ace has free delivery to your nearest store, which for me is 3 miles away. My total real cost for 5 gallons at ACE is less than the real cost for 1 gallon at TSC. Looks like I will have at least 4 gallons of the stuff left over for my fall yard sale! I'll bet I can get at least $10 for the 4 gallons.
