Step 3 - Mounting the Artwork on a Panel

At the beginning of the mounting process I realized that I didn't have a table big enough for the arwork so I had to be creative and decided to place a mirror closet door on top of the smaller table I had available.

 

First I carefully trimmed the extra canvas around my piece. The trimmed canvas at this point is a bit larger than the cradled panel to account for possible misalignments during mounting. The wood panel I always use for mounting my art is an Ampersand Claybord

 

My favorite mounting adhesive is Gudy 831, a very aggressive double-stick adhesive film especially suitable for applications on rough or textured surfaces. It's acid free (pH 7), it passed the photo activity test (PAT), and will not dry out or discolor with age. It's available on rolls with a single release liner. Gudy 831 can be purchased online from Talas in different size rolls. However, if you don't use a large quantity of adhesive as I do or are just experimenting, I suggest you buy Grafix Double Tack Mounting Film which comes in sheets of different sizes. This is also acid free and archival. 

  

After carefully unrolling the adhesive onto the surface of the Claybord, I burnished it with a brayer and trimmed the excess around the edges. I punctured the air bubbles with an X-Acto knife and burnished the area until the air was gone.

 

Next I created a fold on the release liner to expose a 1" wide section of the tacky area of the mounting adhesive.

 

I positioned the canvas over the Claybord and, when perfectly centered, I pressed the canvas on the exposed 1" section of adhesive. 

 

Then I slowly pulled away the release liner while unrolling the canvas over the adhesive. With a sheet of tracing paper covering the canvas, I gently rubbed the surface with a rag until all the release liner was pulled out. As I forgot to take a picture of this step, I'm using a reference from an older artwork. 

 

I turned the board upside down on the mirror to trim the extra canvas with an X-Acto knife.

Here's the canvas mounted and trimmed.

 

I rolled a rubber brayer all over the surface protected by tracing paper.

 

Then I placed the board under weights overnight. Heavy books will do especially with smaller pieces. 

 

Finally I painted the sides of the cradled board with acrylic.

 

On my next post I will talk about the process of getting my artwork professionally photographed.

 

Step 1: before varnishing

Step 2: sealing the artwork

Step 3: mounting the artwork on a panel

Step 4: digital capture of the artwork

Step 5: applying the final varnish

Step 6: framing the artwork

 

Step 2 - Sealing the Artwork

After cleaning up the artwork from debris and cat hair, as explained in Step 1, I taped the canvas on a piece of gatorboard. Any rigid surface like cardboard or foamboard can also work for this purpose. Then I took it outside to begin the sealing process.

Sealing the piece creates a separation layer between the painting and the final varnish. Because the final varnish ages and collects dust and grime through the years, it needs to be removable for conservation purposes; if it sticks to the painting it would be impossible to replace. 

However, there's another very important reason for sealing. In my technique, beside colored pencils, I use wax pastels (Neocolor), both the water-soluble and water-resistant ones, and blend them with heat . If I were to apply the final varnish without sealing, the water-soluble pastels would get wet and possibly smeared by the brush during the painting process. I use a final varnish because I frame my art without glass.  

I sealed the artwork with Golden Archival Spray Varnish, gloss. This sealing varnish contains ultraviolet light filters and stabilizers (UVLS) to provide archival protection and inhibit light damage. It's a mineral spirit varnish and therefore I apply it outside while wearing a dust mask on a non-windy day. I lean the artwork on a wall so that big droplets fall onto the pavement and not on the painting. 

Golden Archival Spray Varnish can be used in place of fixative by colored pencil artists who frame their work under glass. It not only protects from UV damage but it also completely suppresses wax bloom formation, a problem that occurs with some wax-based colored pencils. For this purpose, 5 or 6 light layers are sufficient.

Considering that my piece is very large and needs complete sealing, I sprayed a total of 12 light layers, waiting at least 30 minutes in between. After each layer I bring the artwork inside the garage and let it dry away from sun and moving air. I rotate the artwork from a horizontal to a vertical position at each spraying session and always spray from side to side at about 10" distance. When the sealing process is finished I let the artwork rest inside for a few days. 

On my next post I will show you how I mount the canvas on a 40" x 60" x 2" Claybord.

Step 1- Before Varnishing

I've finally finished my 40" x 60" piece and now I'm preparing the surface for varnishing.

Step 1: I begin by going over the highlights that lost their brightness with a white Neocolor. I will then examine every single square inch of canvas (in this case 2,400 sq inches) with my strongest magnifiers. If you work with colored pencils and wax pastels like Neocolors, you know how easily tiny debris of pigment can become embedded in the surface. The goal is to lightly scrape off the debris and the occasional cat hair using a small X-ACTO knife. This takes some patience of course but it's a worthwhile effort; it's very disappointing to notice debris after varnishing because, at that point, there's nothing one can do. 

I will post five more steps to explore and update the intricacies of my method of glassless framing. After more than 10 years of experience with this method I have developed a reliable technique that I'm always happy to share.
