How to Make Your Vintage Camper’s Sub-floor Watertight

As I'm dismantling the 1956 Shasta I'm noticing how brittle and rotten all the wood is.  I guess some of that can just be age but I was surprised how much wood was left exposed on the underside of the trailer.  Originally it was built using some type of particle board that had a black coating on it.  Then there was plywood on top of that. Then the flooring.  (Two layers of flooring to be exact; Marmoleum and linoleum)

Since my project is a total rebuild I decided to explore how I could make the sub-floor watertight.  I consulted my husband and construction friends and got lots of great suggestions.

But before I tell you my sub-floor secret let me run through how I prepared the trailer frame and underlayment.

With the entire trailer frame exposed, I decided that I wanted to remove all the rust and apply a rust-resistant paint.  I put the trailer up on blocks and removed the wheels.  I started by sandblasting the frame.  My friend Dean lent me his sandblaster and gave me a quick tutorial.  I bought the silica sand that it required and suited up.  Silica can be hazardous to your health so it's imperative that you wear protective gear; respirator, eye protection, hood, coveralls or thick protective clothing and gloves.

Safety is sexy! ok, maybe not in this case!

Unfortunately for me, it was the middle of July and there was nothing sexy about the insufferable heat. I could only work for about fifteen minutes before I thought I was going to suffocate.  (Maaaybe I was being dramatic but I couldn't stand being in that get-up for very long!) Every fifteen minutes I'd throw the hood and respirator off and gasp for air!  My husband thought it was quite comical.  This must have been how Darth Vader felt.  No wonder he was cranky!

After that horrible job was done, (or I just couldn't take it any longer) I used a wire wheel to clean up any areas I wasn't happy with.  I went over the entire trailer, step, hitch, axles and leaf springs.

Then I painted everything with two coats of silver rust-resistant spray paint.



In between coats I got to work on the wheel wells.  They are made of aluminum, 1x1 pine and plywood. The aluminum was in pretty good shape but I replaced the plywood and 1x ends.  I cleaned and lightly sanded them.  I removed any nails and screws and hammered the flange edges straight. Everything got several coats of black spray paint.

Next up was the 2x4 floor joist that runs the length of the trailer.  Since these have been exposed to over 60 years of road grime and water I decided to replace them as well.  In actuality, they are smaller than 2x4 so I had to rip them down to size with my table saw.  I used pressure treated lumber for this so again, make sure you wear a respirator.  There are some blocking pieces as well.  I just used the old pieces as a pattern to measure the new.


I bought new bolts, nuts, and washers, (mostly because I had to cut the old rusted ones off) and drilled holes in the 2x4s to receive them.

While access was easy I decided to run the trailer tail light package.  The wires were just clipped under the old trailer and exposed to the road.   So instead, I installed a length of conduit and fished the trailer light wire through it.  It will be ready to wire the tail and marker lights when I get to that part of the project.

It was finally time to lay the plywood down.  I was careful to use the same thickness as the old because I want everything to match up when I get to the walls and cabinetry.  I used the old pieces of plywood as templates and cut everything to fit.

But...but...but... BEFORE I screwed the plywood down I flipped it over and applied a product known as "ice and water shield".  This is used in roofing to prevent water and ice from creeping in. (You can find it in the roofing department of your home improvement store.) It comes on a roll and can be cut to size.  It has a paper backing that you peel off to expose the sticky side.  AND....It's super sticky! Its tar-like material is thick and water resistant.

Because it's so sticky, my husband helped me put it in place.  (I mean it's like fly-paper-sticky!) We applied it to each piece of plywood and then turned the pieces over so the water shield was facing the road.  Then I cut 4-inch strips of the material and crawled under the trailer and placed them on the seams.  After everything was in place I screwed the plywood down to the wood joist.

Finally, I installed the wheel wells.  They take a bead of calking around the flanges to ensure a watertight seal as well.

Don't forget that this will all get another layer of plywood before the flooring goes down. I put another layer of plywood down making sure they were "bricked".

The wheel well flanges are now sandwiched in between the two layers of plywood.

I definitely feel much better about the level of moisture protection my little camper has now. The next phase of this project is the flooring.

Check out my next blog post for how I did it.

Easy Burlap Chair Sashes

Make perfect burlap chair sashes in just minutes! So easy!I just love how these turned out!  The really make wedding chairs look extra special.  Just adding the sash can make a simple wedding venue look AMAZING!!!  They are super easy to make as well.  Here's how I did it:

Materials you'll need:

  1. Burlap by the yard
  2. Scissors
  3. Thread in a matching color
  4. Serger or sewing machine
  5. Jute String

I have a special way of tying them because they are so bulky.  I'll get to that later.  But here's a'll need some jute string so, put it on your list too. 🙂

I've included a link to the product I purchased.  (100-yard roll)

Here's the jute string link.

I cut the burlap into 90" lengths.  You can adjust the length of your sashes to fit your specific char.  I used a white folding event chair for my measurement.  The sashes won't be tied into a bow so this length will put these sashes hanging on the floor. That means I can get approximately 40 chair sashes from each roll. When I calculate the shipping that's under $2 per chair sash. (That is including the shipping on two rolls so it would make about 80 sashes.)   Pretty great, right?

FYI-Cutting and surging this project is really messy!

Now you're ready to finish the edge.  I used my serger sewing machine with beige thread. I surged all sides and then clipped by threads. You can use a regular sewing machine on a wide zig-zag stitch.  Keep the stitch length somewhat close together to prevent the burlap from unraveling.

Here's a quick video showing how I turned the corners.


Now let's tie them!  Simply place the sash around the chair and cross in back.  Use an 18" length of jute twine to tie the sash where they cross. I tied a tight knot in the jute twine so it wouldn't slip.  For an added special touch you can tie springs of lavender, baby's breath or flowers in the jute twine before tying a bow. Tip...use tried flowers to prevent wilting on your special day.  They stay perky and the color doesn't fade.  Baby's breath is pretty hearty so you could use it fresh.

That's it!  So easy right?  I guarantee that it will make a big impact on your event.

Tip!  This width and length also make a great table runner.  It's more narrow than most runners and that's why I like it.  It allows more room for your table setting on rectangle dining tables.  I've also used them as tie backs, on mantles, buffets, entertainment consoles and couch tables.  So many uses!
