    Hello all,

    Hope we all have our air cons on full blast and that your vinyl isnt melting as it sits on the shelf.

    As the title suggests I have been asked to vinyl the interior walls of a portacabin. These are covered in a textured finish, not seen the actual one but are these not just a cheap wall paper and we should be able to apply MD5 block out over the top.

    TIA

    Iain

    i would be concerned as its likely to be low energy. Definitily do a tester first as you may need a HT film

    is the surface like this attached image, Iain?

    they normally are, but “this is a very close up photo” zoomed in, so appears much flatter.
    not all, but most are made from a thin metal sheet or grp that’s coated in a grained PVC coating, called plastisol which comes in about 60 colours and has a 25-year colour stable life. its repellant to many things and for this reason is used to clad factories, portacabins and so on.

    it will take vinyl though and because of the natural vein-like grain on its surface, it acts like a bubble-free vinyl.

    in short, your vinyl can be applied to it.

    however, that’s “IF” it’s this type of surface coating.

    As martyn correctly points out. some have a sort of low energy surface, which is normally just a cheaper type pvc coating that is again easy for them to be wiped clean.

    I have been using this plastic-coated metal in 10ft x 49inch deep sheets, for around 25+ years now and we buy it in by the ton.
