Varnishes are used as a finishing layer to protect artwork from discoloration, moisture, dirt, and UV rays. Which varnish you choose will affect the finished look. A glossy finish will make colors appear more vibrant, matte will reduce glare and soften colors, and a satin varnish will provide a finish somewhere between glossy and matte. Often preferred over brush application, spray varnishes work well for fragile surfaces that could be disrupted by a brush, or for paintings with a rough or impasto texture where brushes could cause foam or bubbles to form. Make sure work is thoroughly dry before applying, and allow time for the varnish to dry completely after each application. Please note that most of these products are extremely flammable and must be used with adequate ventilation. Our picks below will help you find the best spray varnish for your project.
