Application of Isolation Coat to Acrylic Painting

You need to apply the isolation coat very consciously. As it is a transparent layer you should carefully apply it to the painting so that not to distract them from the brushstrokes of the isolation coat.

If you apply an isolation coat with a brush to your acrylic painting with a considerable amount of texture can produce foam. This might require a spray application or the decision to avoid an isolation coat altogether.

In case of painting involving colored wash or stains, an isolation coat may be very important because the pigments may not be in the binder in sufficient quantity and may bind, making these areas fragile and sometimes very brittle for varnish removal without the possibility of making paint lift.

This fact also means that a spray application of an isolation coat might be essential for you to avoid any bleeding or smearing of the paints.

Before applying an isolation coat, make sure that the painting dries completely. Ideally, take 24 hours to dry the paints before applying an isolation coat.

When you applying, look over the surface of the painting up close to see you don’t have any rogue brush hairs on the surface.

You should use a clean brush and then only use this brush for varnish. It will be tempting if you are in a rush to use another brush that you think is completely clean.

An isolation coat should dry within approximately 10-30 minutes of application. It is best to allow the isolation coat to dry one day before applying a varnish.

If there is a time period of two weeks or greater in between the application of the isolation coat and the varnish, it may be necessary to wipe the surface of the isolation coat down with a soft, lint-free damp rag in order to remove any surfactants that could cause a lack of adhesion with the varnish layer.
