How To Resin Chalk Pastel

Posted on 17 Jul 09:55
Covering your chalk pastel artwork in a coating of ArtResin is easy - in fact, epoxy resin takes chalk pastel pieces next level, sealing and protecting them with a professional looking finish and a glossy sheen that makes colour pop!

We love using our Wood Art Panels here at ArtResin - you can mount your artwork and pour your resin directly in the panel!  With a unique raised lip specifically designed to contain resin - they make for a super easy pour with clean edges!

Measure, mix, pour, spread, cover and wait, and in 24 hours your chalk pastel piece will go from good to gorgeous!

Let's get started .... 



Supplies:
  • ArtResin's 12 x 12" wood Art Panel 
  • a chalk pastel piece of artwork sized to fit the panel 
  • adhesive such as white glue, spray adhesive or a glue stick
  • paper and a brayer
  • ArtResin epoxy resin 
  • nitrile gloves 
  • a level
  • a measuring cup with easy to read measurement lines 
  • a mixing container 
  • a stir stick 
  • spreader or popsicle stick 
  • a handheld torch like our Artist's Torch
  • toothpicks
  • an empty plastic tote or cardboard box with the flaps cut off to protect your piece while it dries

Steps:

1. Complete your chalk pastel piece on paper sized to fit the panel. 





Mount your work directly to the panel using an adhesive of your choice: a glue stick, spray adhesive or brush on white glue with a foam brush.  




For best results, place a piece of paper on the surface of your print to protect it, then smooth it out with your hands or a brayer to ensure that it's evenly mounted, with no air pockets.




A Note On Sealing:

 

We always recommend testing your particular materials out with ArtResin on a scrap piece so you know exactly what to expect before you resin your final project.  There are certain cases, however, when sealing your work prior to resining is required ....

  • Sealing over low quality paper.  It's a good precaution to pre-seal when applying ArtResin over soft or low quality paper that may otherwise absorb the resin, causing dark, wet spots in your work or causing your work to bleed.

  • Sealing over loose material.  With chalk pastel, you want to be mindful of loose chalk dust that might get mixed up and float away in your liquid resin. For this piece, we chose not to seal and instead made sure we removed as much excess dust as we could by regularly tapping the paper against our work surface. However, for peace of mind, you can certainly err on the side of caution and seal your artwork first with a spray fixative specifically formulated for chalk pastel.  

  • Sealing the wood panel. Being an organic material, wood may contain trapped air which can release into your resin as bubbles. There are many variables that can affect gas bubbles: the type of wood, how dry the wood is, humidity etc. Pre-sealing wood with a spray or brush-on sealant is an option to help to prevent bubbles. We've used these wood panels enough to know that we don't need to pre-seal them, but we always recommend testing with your particular materials so you know exactly what results to expect before you resin your final project. Again, if in doubt, you can never go wrong by pre-sealing first if it makes you feel more comfortable.    

 
2. Using our Resin Calculator, simply enter the length and width of your piece to determine how much ArtResin you’ll need.

👉TIP: a standard 1/8" coating for a 12" x 12" panel requires 5 oz resin ( 2.5 oz resin and 2.5 oz hardener ). Measure the lip on your panel as they can vary. The panel in our video, for example, has a 1/4" lip. In order to fill it to the top, you'd use double the amount: 10oz total resin ( 5oz resin and 5oz hardener ).






3. Wearing gloves, measure accurately ( by volume ) precisely equal amounts of resin and hardener. Stir thoroughly for 3 minutes total, ensuring you scrape the bottom and sides of your mixing container as you go. 
👉 TIP: for our very best measuring and mixing tips, read the blog How To Measure And Mix Resin And Hardener.




4. Pour the ArtResin onto the centre of your piece and spread it out to the edges using a plastic spreader or a popsicle stick. You'll have about 45 minutes of working time before the resin gets too thick to work with.

5. Using your Artist’s Torch, hold the flame a couple of inches above the resin surface just long enough to pop the bubbles, keeping the torch moving from side to side at all times. 
👉TIP: if you're nervous about using a torch, don't be! Read our blog with all you need to know about How To Use A Torch On Epoxy Resin.




6. Once the piece has been torched, look at the resin in the light for any missed bubbles, tiny hairs or bits of dust, using a toothpick to fish them out. 





7. With a plastic tote or a cardboard box ( with the flaps cut off ) cover your piece and let it sit for 24 hrs until it’s dry to the touch.




8. After 24hrs has passed, reveal your piece!  
👉TIP: the resin will be dry to the touch at the 24hr mark.  At this point, you're free to hang and admire your artwork on the wall, absolutely, but if you're planning on packing and shipping your artwork, please wait at least 72hrs until the resin has fully cured.
