As you apply layers of paint to your support you will want to fuse (or re-heat) each and every layer to ensure that it is adhered to your ground or substrate. It is important to fuse between layers to prevent them from separating.
• As you practice fusing you will notice that when the paint begins to glisten or shine that is when it is becoming molten again.
• The cooler a paint has been applied the more thoroughly it should be fused, and visa versa.
• A slow thorough fusing will result in a smooth enamel-like surface.
• If you see air bubbles in the surface of your paint a light fusing with your heat gun’s hot air directed at an angle will help to get rid of them.
• Use torches and heat guns to your advantage. Not only are they for fusing, but they can also be used to move and manipulate the paint and create a wide variety of effects that cannot be achieved with a brush.
