ACM Panels or: How I Learned to Stop Worrying and Prepare My Own Surfaces

This past year I made the leap from my old standby surfaces - wood panel or masonite for oil paintings and illustration board for pastels - to ACM (Aluminum Composite Material). ACM is used for commercial signs and is easy to use, easy to frame (it's 3mm thick!), won't bend or warp, takes any surface you want to put on it, is more archival than anything on the market today, and most importantly cheaper by the foot than stretched canvas or commercial pastel papers if you prepare it yourself. A common brand name of ACM is Dibond and you can usually get it from your local sign maker or plastics manufacturer (Pro tip - when shopping ask for ACM instead of Dibond and save yourself $30+ per sheet). I get mine from Piedmont Plastics in Albany, NY. Prices can fluctuate but the last time I picked up a couple sheets it was $65 per 4x8' sheet. Most places will cut it down for a small fee you so it'll fit in your car.

So what do you do with this giant sheet? First remove the protective sticker on both sides (shown above). ACM cuts easily with a carbide-tipped saw blade - if you have a table saw or circular saw you probably have a carbide-tipped blade already. I like to use an 80 tooth blade for a smoother cut but I've read that you can even cut ACM using a utility knife - just score it a several times on both sides and snap it off. 

Once it is cut to size you need to sand the side that you're going to paint on. There's a primer on the panel that you want to scuff up so your gesso will adhere - but do not sand so much that you remove the primer or your gesso won't stick. It sounds scarier than it is: I use a palm sander with 300+ grit paper and very little pressure in a circular motion. The semi-gloss panel that you had before should look matte when you're done. Wear a dust mask. 

Left panel is sanded, right panel not.

Now you need to degrease the panel and remove the primer dust. Rubbing alcohol and a paper towel will do the trick. You're done when all the dust has been removed. If you're not going to immediately gesso your panel then make sure to degrease again beforehand. You want a clean surface.

Use your gesso of choice (actually acrylic dispersion, traditional gesso is something else but most manufacturers call it gesso). I'm partial to Golden's. Paint on a coat of gesso making sure your brush strokes are all going in the same direction and then allow the paint to cure. Notice I didn't say dry. The gesso will be dry to the touch in an hour or two but it won't be cured for about 8-12 hours. You know it has cured when it is room temperature - uncured gesso will be cool to the touch. Ain't science awesome? 

Paint on 4 coats of gesso (curing between coats), with each coat's brush strokes at a right angle to the previous. This will create a slight weave-like texture that will help subsequent layers adhere.

If you're an preparing the panel for oil paint then you're good to go! You can sand the texture down if you like, you can paint directly on the gessoed surface, or if you have a preferred oil painting ground now is the time to add it. 


But what if you want to work in pastels...


Here's the recipe for my patented hand-dandy homemade pastel surface:

  • 1 part gesso
  • 1 part powdered pumice
  • 1 part Golden Fine Pumice Gel
  • Acrylic paint if you want a toned surface
  • A little bit of water to help it all mix together

Store the unused portion it in a tight sealed jar and it'll stay viable for years.

Paint on 2-3 coats. It'll hold your brush strokes if you want them for added texture, otherwise you can go over each coat lightly with a soft brush to remove them.

If the surface is too gritty when you're done a single pass with 300+ grit sandpaper will even it out nicely.

Credit where credit is due: I learned much of this process from Kate Stone's blog and Underpaintings magazine The pastel part is all me though. :)



Arkell Museum Exhibit

I was invited to exhibit at the Stone Wall Gallery in the Arkell Museum/Canajoarie Library in Canajoharie, NY after being in their annual juried show last year. I'm absolutely thrilled to have 13 of my works housed in the same building as some on my idols of American painting: William Merritt Chase, Thomas Eakins, Winslow Homer, John Singer Sargent, and Andrew freaking Wyeth (not his actual middle name, I know)! The exhibit is up through July 1st.

Portrait Demo

Join me this Saturday at the Shirt Factory Gallery in Glens Falls for the opening reception of Artist as Teacher, a showcase of art by artist/teachers from Salem Art Works, The Adirondack Folk Art School, North Country Arts, and the Shirt Factory. I will be exhibiting some new work and demonstrating my portraiture techniques with a live model while providing insight into my process.

Some thoughts on revisiting a piece that wasn't quite "there"

I completed the pastel on the right some time around March. I was happy with it for about a week before The Doubt crept it done? Can it be better? (What the heck is up with that left hand?)

So it sat in the studio for months. Unframed and unloved. I needed to fix that hand, but I was still happy with the dress and general color scheme.

The day finally came when I decided to jump back in, if only to get it out of the studio. 5 hours later and I had redone EVERYTHING. And was 1000 times happier with it.

The moral of this story? Sometimes all a failed piece needs is a fresh perspective.

So finally, here is:

Sketch Club

Every Monday evening from 6:30-9:30 pm I attend the Sketch Club at Saratoga Arts in Saratoga Springs, NY. This is an open studio with a live model doing a single 3 hour pose, usually nude but occasionally in costume. 

And every now and then the model doesn't show up.

This was the case last Monday. But instead of packing up and going home we asked for a volunteer and fellow artist Kelly Smith came to our rescue. Above is my contribution: Kelly, oil on paper, about 12x16", 2 1/2 hr pose.

The Sketch Club has a website where the artists' works are posted every week: There's also information there for anyone who is interested in attending.


Painting in Saratoga Springs this Saturday, June 14th

Saturday, June 14th, 2014, I will be one of twenty local artists painting en plein air (that's French for painting outside. Everything sounds classier in French) on Broadway in Saratoga Springs, NY in conjunction with Saratoga's ArtsFest. I'll be in front of City Hall from 10-4 with a reception following at The Niche Gallery from 6-8. I'll also have a couple paintings hanging in The Niche Gallery during the day. A map to my location is below - The Niche Gallery is just a few steps north of me. Come on down and see some great art being made!

Follow-up 6/15: Had a great time painting yesterday and met some wonderful artists. The weather was perfect in the morning but the wind really picked up in the afternoon. My easel kept trying to fulfill it's apparent lifelong dream to become a kite. I still managed to pull off 2 paintings - an 11x14" of City Hall and a tiny 4x4" of the Collamer Building.

Here's a not-so-great iPhone pic of yesterday's plein air painting, framed. There are some subtle violets and blues in the window that the camera didn't pick up at all - but the painting sold at the reception so this is the best image we're going to get!
