Varnish is a clear coating that painters apply to an oil painting after the paint dries fully, which usually takes two to three weeks. Varnishing the canvas is a crucial step for the following reasons:

- __Adds a protective barrier__: Varnish, also known as picture varnish, is a protective top layer that can keep a painting scratch and dust-free. “Once dust gets into the painting, it's really hard to get out,” Devon says. “With the varnish, it's sort of like a protective barrier.” Many varnishes contain ultraviolet light stabilizers, which prevent color changes from UV damage.
- __Keeps the color vibrant__: After the drying process, particularly for oil paintings, the colors and pigments become dull and matte. A gloss varnish brings colors back to life. It gives the dry paint a glossy, vibrant finish. A matte varnish protects paintings from the elements, but a matting agent will give the painting a matte finish with less intense colors.
- __Protects paintings from aging__: Varnish also protects an oil painting from the effects of aging. Conservators remove varnish with mineral spirits and turpentine, then retouch varnish to prolong the life of a painting. “Years down the road, if you ever become a famous artist, a conservator could remove that varnish, all the paint is gonna be pristine as if you just painted it,” Devon says. “And then they could reapply varnish.” When varnishing acrylic paintings, removable varnish products generally require an isolation coat to separate the paint from the varnish.
You can choose from different types of varnishes, including spray varnish for easy application or a quick-drying loss varnish that you can use two to three weeks after your painting is dry. You should apply most traditional varnishes six months after you finish a painting, and it is completely dry. Paintings with impasto, or thick paint layers, can take longer. Here’s Devon’s step-by-step tutorial on how to varnish an oil painting using varnish and a foam brush: 

1. __Apply the varnish indoors__. Apply varnish to your paintings indoors, in a well-ventilated area that is dust-free and lint-free. “Once you get dust in it, it's super hard to get out, it gets trapped in the varnish,” Devon says. “And then make sure there's no hairs in your varnish.”
2. __Lay the painting flat__. To prevent drips, lay the painting flat. “If you varnish it while it's upright, then all the varnish is gonna drip,” he adds. “It's not gonna be even and consistent.”
3. __Pour the varnish on__. Grab the bottle of varnish and “pour a little bit out” onto the surface of the painting, Devon says. 
4. __Cover the painting with the varnish__. Using a clean soft brush, such as a foam brush, move the varnish around, glazing the painting so a thin coat of varnish covers the entire painting. When using a varnishing brush, make sure you use the same brush strokes throughout. “It doesn't matter which direction you go, but if you do go up and down, make sure the whole thing is up and down,” he says. “And if you go side to side, make sure the whole thing is uniform.” You only need one layer of varnish; you do not need a second coat. 
5. __Ensure you cover the painting__. Cover the entire painting in a thin layer of varnish; it should look wet. Devon advises you “look at it from different angles to make sure the whole thing is shiny.” You do not need to apply the varnish perfectly for it to be effective. “As long as the whole thing is covered and you did it in a consistent fashion, then that's good enough,” he adds. “And when it settles, it's all gonna dry very consistently.” You may also notice bubbles on the painting from the varnish that will go away as the varnish dries. The bristles in the brush strokes will also disappear with time. 

Let the varnish dry before you handle the painting again. The drying time is typically twenty-four hours, depending on the room's temperature. The warmer it is, the faster it will dry.
There are several types of varnishes and finishes that work for various painting mediums. You can find these varnishes in art supplies stores:

1. __Oil-based varnishes__: Oil-based varnishes, which typically include a base of linseed oil and resin, work well on oil paintings, water-mixable oil paintings, acrylic paintings, and alkyd paintings. Some oil varnishes yellow with time, and solvents such as turpentine or mineral spirits can remove the varnish. Oil-based varnishes include Dammar Varnish (also spelled Damar Varnish).
2. __Water-based varnishes__: Water-based varnishes come in liquid varnish and spray varnish products and work best for acrylic paintings. These varnishes include polymer varnish and mineral spirit acrylic (MSA) varnish.

Finishes for varnishes generally include a matte finish, <a href='https://masterclass.com/articles/what-is-satin-fabric-a-guide-to-the-types-characteristics-and-uses-for-satin' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/what-is-satin-fabric-a-guide-to-the-types-characteristics-and-uses-for-satin","linkCopy":"satin","category":"automated-link"}' automatic='true'>satin</a> finish, gloss finish, and high gloss finish.
