if you own a turck this might answer questions about liners and spay on's

I used gray floor paint, seems to be holding up so far.

I'm sticking with roof tar. At $5 per gallon, I don't know how you are going to get much cheaper than that.

I'm not shure, but I THINK most people that checked asphalt really used roofing tar.

Asphalt is a combination of tar, sand, and gravel. Don't see how that would stay on the bottom of a tear.

They are closer than you in definition. See below.

Main Entry: 1as·phalt
Pronunciation: 'as-"folt also 'ash-, esp British -"falt
Variant(s): also as·phal·tum /as-'fol-t&m, esp British -'fal-/
Function: noun
Etymology: Middle English aspalt, from Late Latin aspaltus, from Greek asphaltos
1 : a dark bituminous substance that is found in natural beds and is also obtained as a residue in petroleum refining and that consists chiefly of hydrocarbons
2 : an asphaltic composition used for pavements and as a waterproof cement
- as·phal·tic /as-'fol-tik, esp British -'fal-/ adjective

You're thinking of the term asphalt paving (2) and it is described as an asphaltic composition. The roofing tar is actually closer to pure asphalt (1)but with a fiberous binder added.

I used oil based primer and oil based enamel over it. The 2X framework was epoxied to the plywood floor, and siliconed and through bolted to the frame. I live in a dry climate and the paint will be plenty. The tear is garaged during non use periods.....Doug Hodder

[GeorgeT]

I used the same water based Sherwin Williams exterior paint that is on my house. Not a wet climate here most of the time and I garage it when not in use. If I lived in a wetter climate I'd probably go with some sort of petroleum based product like the asphalt stuff.

Ol Timer,

I looked it up, and you are right. I was wrong. Can someone please change my vote? I used asphalt..not tar.

How can I ever be forgiven?

[Arne]

Asphalt coating sticks to anything. Just try using it, you will see what i mean.

It won't ding from debris hitting it, it won't need redoing in my lifetime.

If it came in white, I'd dot the whole tear with it... ah, maybe not, it is kind of rough.... bad aero....

I wrote a man who has a woodshop site who just moved from NY to Canada and has put his teardrop on hold to rebuild his woodshop and livlyhood.

I would probably use aluminum. We live in the country and the
mice will get through anything else - even roofing tar.

Best regards,

I used asphalt emulsion to coat the entire under floor, insulated it with 1" rigid styrofoam, then coated it all again. Once dry I installed the floor on the trailer, I put a .032" aluminum pan between the trailer frame and the floor. I sealed the mating surfaces of the trailer /aluminum pan / floor assembly with a polyurethane caulk.

Water tight and relatively road hazard proof.

I was at H.D. and they had Henreys 107 asphalt emultion

will that work? Mike can you show a picture of your can??

We used Dupli-Color brand truck bed coating. I rolled it on we a textured paint roll, it gave a very nice looking, durable, waterproof finish.

[norm perkiss]

I used a left over gallon of "Snow Roof". It is used to coat roofs of just about anything. It is waterproof, I think it was water based and stays flexable forever. It soaked in to the wood nicely, first coat. I put 3 coats on the underside.

If it works for the for the life of the TD, great. If not, I can always build another one. I probably would have used the asphalt, but had this stuff one hand. If I remember correctly it was around $20 a gallon.

We have a Coleman tent trailer, there is nothing coating the underside and it is a strand ply of some sort.
