The Big Pink, Foamie !

Good to see you didn't use the Advantek floor sheeting. We have that in
out 1977 Avion and ALL the edges are rotted out and the rest of the floor is
weak. Your exterior ply with the "Mix" treatment seems the best way to go
as you did. Just let a way for the bottom to breath as well.

THANKS FOR YOUR COMMENTS !
I did treat all the old exposed floor inside and I'm removing all the plastic and pink insulation underneath and intend to spray "the mix" with a pressure sprayer.
I haven't gotten much done recently, but did reinstall the water heater and furnace. I added a piece of scrap aluminum to the bottom of the very front so water can't get between the frame and the floor.
My next step is to reinstall the water pump, linoleum on the bathroom floor, and composite flooring in the kitchen.
I'll also be adding a drip edge along the bottom of the sides.
And then I have to rebuild the shower stall and bathroom vanity...

Tac, please look for the sign of ANY leaking ... roof, doors, windows ... We know the manufacturers do a purposefully poor job of modern trailer building .... Their recommended self-leveling caulk is , excuse my French .... Crap !!! We were experimenting with Eternabond tape which was supposedly good for 25 years ... The RV dealer recommended HE re-caulk the trailer once a year .... ( for $1200.00 ...) Ridiculous ... and even with his re-caulk, it leaked and failed anyway ... These are not your Grandfathers trailers which were an attempt to build proper campers .... These are "designed to Fail" , and require expensive repairs , your dealer is so willing to supply .. for $150.00 hour , plus highly inflated materials cost ... It's "good for their Economy" ....

Best get it fixed up and find some place to keep it INSIDE, and bring it out occasionally ... They are really NOT made to live outside ... try not to even wash if you don't have to ...

Wow what a ride! Read the original thread all the way through this one. The Big Pink now has a spot in my heart. I loved reading the evolution of this sizable foamy!

What a transformation!

[GPW]

Well Done !!!

Tac , apologies , but I couldn’t help re-posting that floor damage pic .... that’s so TYPICAL of what happens ... ( picture enhanced for more detail and Horror )

[GPW]

You’ll notice the bottom “Membrane” which is a plastic sheet placed underneath so they don’t have to take the time and expense to properly undercoat the bottom . It takes them much less time to throw a plastic sheet down and build over that ... They don’t even glue it to the floor bottom ... .... we’ve actually seen many many cases where that plastic sheet HOLDS WATER and moisture in , sometimes like a big bubble underneath FULL of water ... certain to quickly ROT an untreated floor ...

[tac422]

Doc,
Just to make sure the plastic held water they put 1" of spun fiberglass insulation between the floor and the plastic.
The insulation literally dripped water as I took it out.

[GPW]

That’s just Ridiculous huh ???  Who builds these trailers , Idiots ....

You know , I’ve never run across a pressboard material that absorbs water so readily , then turns so quickly to Oatmeal ... It either has to be the absolute cheapest material they can find , or it is intentionally done to generate service and repair money ... And why there is not even the slightest treatment to make it really waterproof , I cannot logically understand. On my commercial trailer, making floor repairs , the provided flooring that was not damaged , would literally soak up “the Mix” like a sponge ... I’ve never seen a product do that , save a real sponge ... And we’ll not even talk of the roof , which seemed designed to fail ... and then there were the revolutionary “dry fit “ windows they boasted of , which also leaked and caused de-lamination of certain wall members ... Not your Grandpa’s trailer company for sure ...

Ohhhh! That's beautiful! ...What a difference!

While we’re off on commercial trailers ... The other day I was looking at one of those Aluminum sided camper trailers in the rain . I noticed Rain falls from Up to down . All the metal sided buildings we see have the corrugations running vertically up to down . But trailers have the corrugations running side to side ... If you think about it , that’s much more difficult to drain than a vertical arrangement ... Meaning not only the roof has to be leak free but now , also all the side seams too ... No wonder conventional trailers eventually leak ...

Ps. Oddly enough , we’ve seen several “construction site” trailer looking buildings with the metal run vertically ... and they seem fine lasting for years outside ...
