How to make cardboard look metal???? Answered

I was wanting to know how to make cardboard look metal for like movie props and stuff like that.


Start by sealing the card with any kind of paint. Acrylic is a good choice because it is waterproof when dry. Then spray with matt black spray paint.
Dry brush with matt aluminium paint, or gunmetal paint.
For a metallic 'sheen', get some graphite powder and a soft cloth and rub the graphite into the matt finish paint.
Finally give it a spray with cheap hairspray to seal evet=ything in. You don't say what the final use is but here's a cardboard gun:


Seal the cardboard with sealer then spray it with gray paint. You can spray some areas with a dusting of brown for rust etc. if you want it to look older.

Nice touch re: brown for rust...that's just sweet brain activity imo.

i have used spray-on hammerite - the hammered finish is especially good.

This'll work fine. If you don't want the cardboard "flutes" to show, glue a layer for thick cardstock on first. Then prime, and finish with a metallic or faux-metal spray paint.

I've done a similar thing two different ways depending on the look I wanted. Method 1: Use spray-on adhesive and glue aluminum foil to the cardboard. Method 2: Seal the cardboard with Haymes Paper Faced Plasterboard Sealer and then spay paint it with a metallic paint.

If you want it shiny, you could try one of the metallic spray paints, or for a duller finish just use aluminum paint.
