Epoxy Resin

So it's actually *epoxy* resin. I've been saying poly resin which is different stuff, apparently.
Here is the painting I want to epoxy resin. It's ink on bristol board.
The painting was sprayed with Krylon UV resistant clear acrylic coating, (no photo) and allowed to dry.

Next, I painted the edges and sides of a 12 x 12 box canvas black (the chosen border color). Once the canvas was dry, I used Golden brand gel gloss medium to fix the painting to the canvas.



A layer goes on the canvas and on the back of the painting.

I used this handy dandy tool to smooth the painting onto the canvas. I think I used it originally in a print-making class many years ago. I don't remember what it's called or where to get it. A plastic putty knife would work just as well. I will use that later for the resin.

I smoothed the front and the backside of the canvas.
Then I put a heavy pile of books on top of the upside down canvas, so that the painting will dry very flat.
So, here's the cast of characters for the next part: epoxy resin (it comes in two parts the resin, and the hardener), a disposable stirring spoon and bowl, protective gloves, and the putty knife (not pictured).
Also, make sure the place you are working is well ventilated. Epoxy resin doesn't really have a strong odor, but it still isn't safe to breathe. It's too humid to work outside now so my system is a fan on the resined pieces pointing towards a fan that is in the window.

Also, wear a mask. AND if you have long hair, tie it up.

Mix equal parts resin and hardener. This is important. If the ratio isn't 1:1 the resin won't harden right. Mix thoroughly.

Pour it on the piece. Be careful not to resin your piece to the floor. Resin will bind just about anything together. I once had to knock a piece off my basement floor with a hammer and screw-driver.
Spread it around making sure everything is covered. I also used the mixing spoon or a disposable paint brush to smooth the resin around the edges of the box.

Every 10 minutes or so, use a blow dryer to pop any bubbles that form on the surface. If you skip this step, your piece will have permanent micro-bubbles.
Let it dry. It will be hard to the touch in about 8 hours. Make sure no one disturbs it during the time. If the place it's drying isn't exactly pristine (like a garage maybe), you might need to protect your piece from dust or bugs with a carboard box.
It will be completely cured in maybe 3 days. Resin self levels, so there is no need to fuss over it, with the exception of the micro-bubbles.

Old work made new and a Commission

These were painted in 2005. They had been in storage until 2009. When we moved I decided to hang them in the house, and they have been exposed to sunlight during that time, but haven't faded noticeably. I varnished them today with one coat of permanent Liquitex Gloss Varish. The varnish retains a wet look after drying, which causes the paint to look as saturated as it did when first applied.

This painting was an experiment with acrylic, watercolor pencils, and ink on wood. I sprayed the final painting with a fixative to prevent the ink from bleeding, and then I applied a layer of poly resin. The resin gives the painting a thick glass like coating. I really like the effect.

This painting was done in ink and acrylic and various texturing mediums, sealed with a coat of Gloss Varnish.
