There are a few options for flooring- one layer, 2 layers, wood, wood and lino, wood and plastic composites.
We wanted a natural flooring, so opted for wood. We used a base layer of 18mm hardwood ply, then recycled cedar tongue and groove boards on top.
We began by doing a final clean of the chassis, then applied 3 coats of chassis paint.
Then we measured the space, and determined how many sheets of plywood we would need. It ended up being 2 sheets of the 18mm hardwood ply. We shopped around, and concluded Wickes had competitively priced ply.
We measured and marked up the ply, then cut the pieces using a jigsaw. We check the fit of the pieces, then we removed them and painted the ply: using tough underbody car paint for the underside of the ply, and external wood paint to protect the topside.
Then the ply was reinstated inside the trailer in order for us to drill holes into the wood to compensate for where the axle bolts stand out. We drilled upwards from the underside of the trailer straight through the existing axle bolt holes in the chassis, into the plywood.
We decided to weld on an extra plate for the ply to sit upon. This was made of flat steel, held up by 2 gussets at either end of the plate.
We also added wooden spacers onto both axles, which were a little lower down than the rest of the chassis. This meant the floor could be screwed flat onto the spacers.
Most of the fixing of the floor was done with 4mm screws that went into both the wood and the metal.
But we used bolts to attach the floor in a few places, drilling out a hole, then tapping the hole to create a thread that the bolt can grip, removing the need for a nut on the underside.
And the first floor is fixed down! A very exciting step, as we can now move around inside the trailer 🙂
Internal Walls
To clad the internal walls with wood. The spaces were measured, then pieces cut to size.
Each piece got 3 coats of external wood paint front and back.
We used 25mm long M8 bolts screwed into threaded fasteners to attach the wood to the trailer. This removed the need for a nut on the inside.
2nd Floor- Recycled Cedar Wood
Now we can start decking out the interior to work as our mobile kitchen.
