Varnish brush for varnishing large acrylic paintings
Reader Question: Hi, I am about to varnish a 36" x 48" painting. Is there a larger brush size you would recommend and if so, which brand or does that matter?
Thank you for posting this great information.
For varnishing such a large painting, I'd recommend using a larger brush size, something between 2 to 4 inches wide. It's important to get a good quality brush for varnishing, so that you're not picking brush hairs out of the varnish. Also, a brush that has softer, smoother brush hairs will help you achieve a smoother, more even finish. Try to stay away from brushes that are "bristle-y" and stiff, if you know what I mean!
Here are a few large brushes that are designed for varnishing large acrylic paintings. They can also be used for gessoing and painting, but I prefer to aside a special brush just for varnishing, to ensure that it stays in good shape for as long as possible.
A natural bristle brush available in widths up to 102mm (4 inches).
A synthetic brush available in sizes up to 80mm (3.14 inches).
A long-handled hog bristle brush, available in widths up to 100mm (almost 4 inches).
