Types of Acrylic Varnishes
Varnish comes in many types. You have to choose the one that best fits your paintings.
Removable vs. Permanent
If you decide to use removable varnish, make sure you apply an isolation coat beforehand. This way, your painting will be protected from the chemicals that will strip away the varnish.
Resin vs. Polymer
Both resin and polymer can effectively protect your artworks from scratches and weathering effects.
However, their application can be quite different. Here’s a quick comparison:
Acrylic Resin Varnish
Acrylic resin varnishes give a clear, glossy finish to your paintwork. So if a high-gloss finish is what you’re after, this is the one to go with.
To dilute it and clean your brushes, you need mineral spirits. Using water won’t work with this type of varnish.
The only problem with resin varnish is that it can be hazardous to your health if inhaled. So make sure you’re in a spacious, well-ventilated area.
Acrylic Polymer Varnish
Polymer varnish, on the other hand, isn’t toxic. So you can safely use it anywhere. It’s made up of synthetic materials, which make it smoother and easier to apply.
It can be thinned using plain water. Your brushes can also be cleaned off with water and soap.
Glossy, Matte, or Satin?
Both resin and polymer varnishes are available in three categories. You can choose from glossy, matte, or satin depending on what kind of finish you want for your painting.
If you want to take things up a notch, you can mix them together. Some artists layer them to alter their effects and give their painting a different aspect.
Glossy varnish brings out the colors in your painting and makes them pop more. Yet, it makes the painting have a mild shiny reflection.
This will be especially noticeable when you take a photo of the painting, or when the light hits it at certain angles.
Matte varnish gives less glare and reflection. It works to make darker colors appear somewhat lighter. This varnish gives paintings a flat finish compared with the other types.
Satin varnish also reduces the glare of a painting. It gives an effect that’s somewhere in between glossy and matte finishes.
Tips for a Perfect Varnish Finish
Keep reading for some tips on how to get a perfectly varnished painting.
Whether you choose a spray or liquid varnish, keep an eye out for places you might have missed. You may even need a second coat to make sure you’ve covered the artwork completely.
If you’re using spray varnish, shake vigorously to mix the chemicals inside. And remember to clean the nozzle regularly. This prevents foam particles from spewing out and clinging to the surface of your painting.
The best time to apply varnish would be a day or two after you’ve finished painting. This gives time for the paint to dry completely.
This is the time when you can add an optional isolation layer, too. If you do apply this layer, you should wait for another couple of days to allow it to dry before applying varnish.
The best type of brush to apply the varnish would be a relatively wide, flat painting brush. It’s even better if it has split-end bristles since this wouldn’t leave brush strokes over the final piece.
You’ll also need a glass jar or any type of clean container to put the varnish in. It needs to be completely clean, rinsed, and dried before you add any varnish to it.
Summarizing Pros and Cons
Using varnish on your acrylic painting can bring out many of its best qualities. Yet it all comes down to your personal preference as an artist.
Here are several benefits and drawbacks of adding a layer of varnish to your paintwork.
