Crackle products offer an easy way to create much more interesting craft projects. Whether it is a decoupage project that you are working on or a mixed media piece, crackle product will let you create a truly inspirational item. Although there are numerous different brands of crackle mediums available, there are two basic types of crackle products – one component (one step) and two-components (two step) crackle mediums. The basic difference between these two groups is the technique used to apply them. Additionally, each of these types renders different visual results. As with other decoupage and craft products, crackle mediums also come in formulas crated specifically to create larger or more subtle cracks, antique effect and so on.

One component crackle mediums create the effect of cracked paint. Besides the fact they are inexpensive, these products are great to start learning how to use crackle products for your decoupage or other craft projects. One step crackle mediums can be applied to almost any surface – wood, glass, paper, stone, etc., and the basic application technique is very straightforward.

What one component crackle mediums do is quite simple – applied between two coats of paint the medium will make the top paint coat to crack creating the effect of aged, cracked paint. The application technique is quite simple:

  1. Apply a coat of paint to the surface. Wait to dry completely.
  2. (optional) You may apply a coat of crackle medium directly onto the surface of your item – it will cause the top layer of paint to crack revealing the surface.
  3. Apply a layer of one component crackle medium over it. Wait to dry completely.
  4. Apply a contrast layer of paint over it – you will notice cracks appearing almost immediately, revealing the first paint coat.

Once everything is completely dry, you can proceed to decorating the item with decoupage using paper napkins, rice paper for decoupage or any other paper cut outs.

Although the basic technique for applying one step crackle medium is very straight forward, there are several things to be careful about:

  • The tool used for applying crackle medium determines the shape and direction of cracks: crackle medium applied with a sponge brush will result in random cracks, while crackle medium applied with a brush will render even cracks which will follow the direction of the brush strokes.
  • The thickness of the medium determines the size of the cracks – the thicker the layer, the larger the cracks.
  • Paint applied on top of a crackle medium starts to crack almost immediately. To achieve professional looking results always follow this basic rule – never paint at the same spot twice.

One component crackle products are pretty straightforward to use and render beautiful results. Using this basic crackle technique will make your decoupage projects much more interesting and truly unique.
