"Studio Tip - Varnish. Why and With What?"
Welcome back to another BobBlast!
I apply a final coat of varnish on everything... Everything! Generally, a coat of varnish is the final protective coat applied to a painting. Not only will it protect the painting surface from scratches or accumulated dust, but the painting will have a richer looking finish. Much like rubbing furniture oil on your wood table top - the entire surface has a uniformity to it!
Varnishes are sold in art supply stores and hardware stores. There are two types:
1) Water-based varnish for acrylics (dries clear)
2) Oil-based varnish for oil paintings (may have a warmer finish - it's oil!)
There are 4 sheens - your choice...
*Gloss
*Semi-Gloss
*Satin
*Matte
In this week's BobBlast, I demo my technique of applying acrylic, water-based varnish to a painting on paper and another larger canvas. I also demo using Dorland's wax Medium as a varnish you buff on the painting!
Click here to read a handout I provide about Varnishes in my workshops.
Bob's Tip & Techniques about Applying Varnish
*Do not shake the can or jar of varnish. Instead, stir gently
*Follow the instructions and use a soft 2 inch wide brush
*Brush on the varnish in one direction - rather than back and forth
*Two thin coats - brush on gently in one direction only
Because I use an acrylic varnish on top of my acrylic painting, I can continue painting on top of the varnish - It's all acrylic and compatible!
Now go paint!

For a very long time I wanted to know about vanishing. After watching the video I will start varnishing all my art. Thanks bob
Thanks for sharing all your wonderful tips and teachings😇😇
Thanks so much! This was great! Really positive and great vibe.. Subbed
You're welcome!
Always good tips! Thank Bob!
Thank you Bob, thank you very much. Keep up the good work.
Great tutorial, Bob!!! You're fantastic!! Thank you 😃👌
Thank you so much. Watching your video gave me the confidence to tackle this task. Cheers!
Wonderful pieces you varnished, there, Bob!
wow love his work
Came here to learn about Holbein varnish application, appreciate the insight!
Good tips here - thank you. i sometimes use Minwax polyacrylic in the acrylic paint to get a bit of light refraction like oil paints.
Great!
Thanks 😊
Love you Bob😁💙
Gracias , gracias , gracias no entiendo tu idioma eres un buen maestro...desde Barcelona España
Bob, thanks for your great tutorials. I discovered your channel while looking for ways to frame acrylics on paper. Loved your piece about using the wood panels. Game changer! I have been researching ways to seal & protect the pieces. The use of Dorland's wax is very appealing. There is conflicting information about whether to varnish before using the wax. Most people use glass varnish first as an isolation coat. What do you think? Also, can the piece be waxed or varnished after it is applied to the board? thanks for all your help, I love your work.
Learning a lot. Can you share about your recommendation on varnish finishes depending on the painting style?
Don't know if that's the one but Golden has a varnish that can be removed with ammonia if you ever needed to remove it.
I would have liked to hear why and which one we use for the type of art produced. What mediums shouldn't have varnish etc.
Treat your varnish like your martini...stir not shaking...Thanks Bob
The polycyclic made my paint lift from the canvas. I use a semigloss clear coat made by Rust-Oleum.
I don’t use rust oleum so I don’t know why your paint lifts. Not dry enough?
Great video! I have the Minwax Polyacrylic protective finish....can I use that over an oil painting? Thanks!
As Bob points out many times you can paint oil over Acrylic base but not Acrylic over oil,it will peel.
Was that a horse at 3:30? Nice effect!
Bob, Why do you recommend water based and not oil based varnish from mini wax?
The oil based will yellow over time.
Does the hardware varnish have UV Protection?
How do u clean your brush???
Is the varnish naturally so liquid? Or you added water?
Hey Bob great tips, just had 2 questions though. Would appreciate your thoughts on these - 1. There is a 3rd kind of varnish called 'Satin' varnish...any comments on those? 2. I've noticed that when I use Gloss varnish it makes it hard to take photographs of my canvases because the light reflects from the entire surface. Would you recommend only Matte varnishes in that case? Thanks in advance, and much love from India!
Minwax makes a polyacrylic varnish that produces a satin finish. I've purchased it in the paint department of our local department store; but, you could probably find it in any hardware store that sells paint and paint products. Make sure it is water-based when you buy it.
The Minwax polycrylic comes in a matte finish. I agree with what you said that it’s difficult to photograph with the gloss finish.
I only use satin or matte because of those very reasons. Krylon also makes a wonderful finishing UV protection spray that I use on my acrylics/inks/watercolours etc. It is a spray, however, it's affordable and wide ranging.
Best to photograph your paintings before you varnish them otherwise you get light bounce.
@@angelreading5098 thanks.
Why isn't the varnish smearing the paint?
Because Acrylic is waterproof when cured.
Can I use the cat to varnish? 😬
I assume you don't paint on the Dorlan's wax...
That is correct!
Thank you for your video! I am planning on gluing pastel paper (that has spray paint on it) onto stretched canvas. It is a large piece. 12" x 16" , and other 12 x 15, etc. I have quite a few. I want to use a larger canvas, such as 20 x 24, and paint on the extra space to unify that painting on paper with the extended background. This way the painting will have less-busy breathing space. After painting the canvas (and I may do some of these on wood panels) I don't want the edges of the paper to be obvious. Will the minwax varnish fill in the height difference and the paper can then visually blend with the background? What are your thoughts?
Hi Maureen - My thoughts are: I don't hide the fact this is a paper piece adhered professionally to a panel. In fact, I show it off and emphasize the deckle edge. The varnish will not compensate for height difference. Hope this helps!
