What are the advantages of using Liquid Mask?

As the name suggests, 'Liquid Mask' (70.523) by Vallejo is a liquid-based masking agent, specially formulated for use by modellers. Liquid Mask can be used either in combination or as an alternative to traditional masking tapes or sheets to mask off areas prior to painting.

Liquid Mask can be applied directly over painted surfaces or onto clear plastic transparencies. It can be applied by brush or through an airbrush (recommended nozzle 1.4-1.7 mm) although if being applied over a painted surface it is essential that the painted surface is completely dry first. It will generally dry after 30 minutes but it is good to leave it for longer, especially where larger areas have been covered or if multiple layers have been applied. When dry, the applied mask will go completely transparent which can be a helpful indication that it is now ready for additional coats of paint. Liquid Mask can also be applied to uneven surfaces and unusually shaped contours where it would otherwise be tricky to apply traditional masking tape.

The Liquid Mask can be removed when the required painting has been completed. The mask can be removed in a number of different ways depending on the precise contours of the model, including a toothpick, a sharp hobby knife or a damp wide bristled paintbrush.

Liquid Mask can also be highly useful in the application of certain weathering effects, such as rust. Firstly, an appropriate rust-based undercoat should be applied to the area in question. Next, apply the Liquid Mask but in a haphazard or random fashion. This can be achieved by a small amount of mask applied to a small section of torn foam backing from a scouring pad, or by flicking Mask from a brush via a toothpick or other brush handle. Both of these methods will cause a suitably random pattern to occur. Once the mask is dry the appropriate top coat of paint can be applied and when this is dry the mask can gently be removed to reveal the rust-based undercoat. It can be beneficial to leave small areas of the mask in place as this can give a three-dimensional effect that complements the application of the mask. Additionally, this technique can be used in combination with other weathering techniques such as powders to create a really stunning visual effect.
