All that glitters may not be gold, but it can look a lot like it when you know how to fake it. If you find yourself in need of a lot of the glittery substance and the real deal is too precious for your particular situation, a few inexpensive materials and a couple of hours of crafty alchemy can transform an ordinary space into a vault at Fort Knox. The secret is in the can---of gold metallic paint, that is. Containing fine, shiny brass powder, it makes an excellent substitute for gold when facade is all that counts.

  1. 1

    Shape the foam blocks into bricks with tapering sides, using a sharp knife. Each brick should be shaped like a long, low truncated pyramid or loaf. Size is not critical as gold bars come in a wide variety of sizes from 1 gm to many pounds, but keep the proportions roughly two or three times as long and high or wide.

  2. 2

    Mix a quantity of plaster sufficient to coat one or two bricks at a time in a large bowl according to package directions.

  3. 3

    Push a skewer into the bottom of each brick to use as a handle for dipping it in plaster.

  4. 4

    Dip each foam brick into the plaster in the bowl to coat it on all sides. Plaster should be the consistency of double cream at this point.

  5. 5

    Set the coated bricks aside on a wire rack until the plaster hardens. For a complete cure, allow at least 24 hours or until the plaster is no longer cool to the touch when held to your cheek.

  6. 6

    Use sandpaper to smooth and even out rough areas once the plaster is completely hard.

  7. 7

    Wipe off any plaster dust with a damp rag and allow the wet areas to dry all the way through once more.

  8. 8

    Spray the bricks with gold paint untilthey're lightly coated. Repeat several times, using light coats each time and letting them dry a few minutes between coats to produce the best finish.

  9. 9

    Let dry for the period recommended on the paint can before using.

Tips and warnings

  • For best results, make sure every bit of the foam is covered with plaster before painting. Many spray paints contain solvents that can eat into and dissolve unprotected foam.
  • If you want to put letters on your bars, use stamps designed for leather work to press the numbers and letters into the foam before plastering.
  • Wear gloves, a paint mask and eye protection when spraying paint, and always paint in a well-ventilated room or outdoors.
