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?


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.

When hoping for a perfect varnish finish, in addition to keeping the temperature up in the room, it is also helpful to fine mist the air with water several minutes before applying the varnish to weigh down any floating dust particles that might be in the room.
