Teardrops n Tiny Travel Trailers

What's good to use for undercoating the bottom of the floor to keep those nasty road salts(chemicals) and rain spray from soaking into the plywood? Any ideas??
Thanks in advance!

Asphalt emulsion, a gallon will more than cover a 4x8.

they ought to call it attack emultion,,I swear I think the stuff will jump 5 ft out of the can to get on ya,,I dont care how careful or slow you go it WILL get on you,,,,ya been warned,,,but its good for the purpose of sealing the bottom,,,,

This is what I used!

Greetings,

Anyone ever use the spray undercoating you get at the auto parts store?
If so, how did you like it and would you use it on another TD/TTT?

TIA,

Eagle

I have seen a couple of TDs that used the Rhino sprayed-on bedliner, but I can't remember who.

I used roof coating from home depot. I think it will hold up for a long time. One gallon for about $7.00... by a heavy applicator brush, throw it away when done.

I used driveway sealer but fear it may be too porous. Woulda used roof sealant/putty but it seems too thick to spread without lotsa trouble.

I tryed the spray stuff and it sucked ,,wouldn't stick good and comes right off when dry,,get the stuff in a can..thats what I did the second time..

I have seen alot of ways the seal the bottom of a teardrop. Spray undercoating, roofing tar compounds, varnish, epoxy, metal, and fiberglass etc. I think that they are all good ways of protecting the underside of a teardrop. I plan on using on the second teardrop I am building to use fiberglass and epoxy resin process that Steve Fredrick used on his tear. I like the way the process penetrates the the fiber of the wood and plasticizes it as a water proof barrier as he states. It may be alittle more expensive, but, well worth the piece of mind of water damage on the underside at the attach points and frame rail contact areas. It has always been my experience that out of sight out of mind areas, like the underside of anything. That the damage is only noticed after it is to late. Just my opinion

I concur with Woody. Besides that is a good place to practice playing with epoxy and glass. If it looks bad only the worms, mice and snakes will notice.

Your right about the practice playing with the stuff

The Wet Stick Roof Coating that I used is not coming off any time soon. It's actually impregnated itself into the wood. And it was cheap too! And brushing it on was really easy.

I only have 2 types of this stuff local. A Kool Seal brand in a white and blue can and a Gardner brand in a red and black can. Anyone have any comments?


BTW: whats the drying time??

Woody,
Unless you REALY need the practice,:wink: I wouldn't waste the money on the bottom of the trailer. I used roof coating, as most do, for $5/$6 per gal. As long as you don't try sailing the tear,:wink: you shouldn't have any trouble. I use the epoxy/'glass for it's waterproofing AND structural benefits. The way I like to stretch plywood kind of "requires" reinforcement.
