Covered every inch of the floor and noticed a huge difference in sound on the road.
The furring strips were glued straight to the sound deadener in the deepest three grooves.
Coated the wood in polyurethane for water protection.Marked the ends of the furring strips to know where they were after putting down the plywood.
Using the eucaboard tempates to mark the SSR for cutting.
The plywood was cut a 1/4 inch from most of the edges to prevent rubbing on the van.
Three coats of spar polyurethane on all of the sub floor plywood. I didn’t sand the polyurethane and used a foam roller to add even more texture so the lifeproof planks would grip.
The back piece of plywood was about 1/8″ off, not quite level because of a seam that Mercedes paints on. I cut it off from other places in the van to make the plywood level with the ridges in the floor but missed the sections around the wheel wells. The Lifeproof flooring was still level aftewards though.
Used some twine for a screw line.Neighborhood cat visits during the build.
Secured with stainless screws.
Set some inch wide pieces of the floor before the caulking to prevent shifting.
Backer rod at the edge of the plywood and below the vinyl flooring.
