Before you varnish, take the following into account:
Ensure the varnish and your painting are at room temperature during application and drying. If they are not, a white cast may appear on your work, since changes in temperature can cause condensation under the layer of varnish.
Shake well before use. Apply the varnish in a thin layer, holding the spray can approximately 40 cm from your work. Only use the varnish in a well-ventilated room.
Make sure to apply varnish in a single layer only. Multiple layers may cause inconsistencies in sheen.
