    Floorboards, painted or not

    Hello all
    In the process of making replacement floorboards for my 1960 PA18-95. The original floors appear to be varnish, then at some point painted over in black enamel.

    Question is what's original?

    Piper reference material indicates that all wood was finished in varnish, but then I also read that all cubs came from the factory with black floors.

    My plan was to used two part urethane varnish but looking for originality.
    Thanks
    Scott

    Original would have simply been a marine varnish. I would recommend Epifanes single part varnish if you want to get fancy or simply Minwax Helmsman Urethane if you want something more simple to apply.

    I have used Epifanes and found it to be a very tough product for floorboards.

    The 5 original Super Cubs I rebuilt had painted floorboards. Probably had some kind of varnish applied first. From the factory in the mid 70s:

    From looking at the inside of the fabric on some never recovered Super Cubs and these original factory pictures I determined they shot the black on the floorboards after cover and paint but before the bootcowl was installed.

    I stain them black and then brush one coat and spray subsequent coats of epoxy varnish on them.

    I am with Steve - just did my Decathlon exactly that way. Rugs were hideous.

    Dealing with an old beat up floor, (or new floor?) I had pretty good results by applying black Aerothane, catalized but no reducer. Clean and lightly scuff old plywood floor and apply paint with a roller, continue to “stipple” the paint with roller as it thickens until you get desired texture. Texture will act like non skid as well as hide imperfections in floor.
    Add flattener to paint if matte finish is desired.
    this can be done with minimal masking, in the plane.

    Thank you
    This makes sense based on what I see on this aircraft. I don't like the notion of spraying after assembly, especially given all the time I've spent stripping, media blasting, priming and painting all the floor-mounted stuff. I had concidered staining the floor black followed by epoxy varnish and that sounds good to me.

    I'm all for exceptions from originality where the oem motivation was time saving!

    Thanks everyone for your help
