Sealing holes, breaches, ensuring few insects enter unnoticed…

Well, how did we seal all those holes from the previous owner’s shoddy RV install? How did we cover up every breach from all the rows of seats bolted into the floor? You’ll find out in this article LET ME TELL YOU.

First, I wanted to get something substantial over the holes in the floor that were made for the toilet-to-blackwater tank, and various other holes Prev-Owner-Guy had drilled into the floor. You’ll be delighted to know he even cut out parts of the frame for these PVC pipes–so great was the need to “put a shitter there.”

Here’s a shot of my tools and materials:


Soooo, anyway, we’re here to talk about sealing the floor. I checked in with some local HVAC companies, knowing they cut from large pieces of sheet metal, to see if they had any scraps they’d sell me. I walked out with several pieces around 24,” which I intended to use directly on the floor. I went with this not only because it cost about $2, compared to the well-over 50$ it would have taken to buy individual similarly-sized pieces of flashing from the hardware store, but I also chose this metal because it is much more durable than the flashing you can buy locally. I mean, this stuff is the professional grade, and you can tell the difference in your hand. Sorry I don’t have a good shot of all the metal we acquired, but you can seem them installed below:


This will cover all three holes. I’m happy with that because it solves my problem quickly. (This is a time-crunch project, remember. Also, I’m not trying to build one of those fancy wooden-walled yacht-wannabe skoolies… This one’s “crunchy.”)


We removed the propane water heater (though we may later re-install properly, as it was loose and leaking in water from all sides (no seal or anything. Lovely.) To seal the hole, I firmly pressed the sheet metal to the outside while using self-drilling screws; I then filled it in from behind with the expanding foam. I wasn’t sure how it would turn out (ugly, sure), but its very effective. You could even give the patch a solid round-house kick and its not going anywhere.


Here are the finished installs of my floor patches:


They’re not the prettiest, but wait til you see the end pic with the 2nd layer of Rustloeum! Also, I chose rounded, flat-ish screws with a metal-tapping end (to go through the metal, of course.) When I install my floor, I will be using foam board, and I figure that stuff can just squish onto the screws a little, or I can “notch” them out, if needed. Its not like I want to live in this thing when I’m 70, so I found this adequate, fast, and affordable for patching giant holes in the floor. (The biggest was like 3″x3″)

Okay, next, how to patch the over-100 holes in the floor? They were too big for traditional “sealer” to fix, so we sought a creative solution… it cost just a little over $1 (well, the tube of E6000 was about $6):


And the process, so beautifully simple:


Now, a shot from the back, with all the patches. Can you believe all the holes!?


After sealing, and allowing to dry, we painted on our second layer of Rustoleum Professional. I like the white because it brightens the inside and looks super-clean. Plus, it was the only option aside from “tractor green.” Ick!


This time, we painted up the sides, and covered all the stuff in the front driver’s area that didn’t get the first-time around covering. For comparison, here is a shot of the first layer:


and a shot of the SECOND layer! If you look closely, you can see all the patches, and the overall way-more-finished look to it. I’m happy enough to move my stuff in there, now that its clean and sealed.


That’s all for now!
