Vallejo's waterbased acrylic varnish with a new, quick drying formula, and an acrylic resin of extraordinary hardness and permanence. Protects painted models from dust and scratches, dirt and humidity. Acrylic Varnish should never be applied until the paint has dried completely (see note), and it is recommended to wait at least 24 hours. Varnish should be applied in fine coats at approximately 5-10 minute intervals.
Note: If a varnish is applied with a brush, the coat is thicker and more time must be allowed for drying; also the contact with the brush and the movement of the brush will disturb the coat underneath, so that it is very important that the varnish has thoroughly dried. These same varnishes applied with an airbrush in fine layers dry indeed in 10-15 minutes, and since the airbrush does not disturb the previous thin layers, additional coating can be quickly applied.
