This is my first attempt at pouring paint over four objects at the same time. I found cheap sandstone coaster, shown below, at the Dollar General store and thought they would be perfect for my first attempt.
I put a piece of parchment paper on the back of the coaster and taped the edges.
I applied two coats of primer, and lightly sanded the coasters after the primer dried. The holders were a stack of four craft sticks held together with the weaving loom rubber bands.
I let my sister pick the colors. She likes purple/blues with green accents. Yes, I use cheap Walmart brand bags, the ones that are almost impossible to get open, to let the paint drip on.
Lastly, it came time to put resin over the coasters. These are the tips I learned while researching how to apply resin (because I have never been very successful):
- Clean the painting of any oily substance. I let the coaster dry for at least a week, then sprayed the coaster with a mixture of Dawn and water. I let them sit for a minute and gently wiped them off with a paper towel and let dry for another week.
- Seal the painting, because canvas breath and can cause air bubbles in the resin. I seal the coasters with polyurethane and let dry for another week.
- Pour resin in temperatures above 70 degrees.
- Use torch to remove bubbles.
- Cover the work with a box while it dries.
I mixed and poured the resin over the coasters, spread it out with a plastic paint scraper, and removed the air bubble with a heat gun. Yes, I know a torch is recommended. But, while researching torches I scared me that I may burn down the house if the torch did not fully extinguish. So, I was very carefully to keep the heat gun cord and my hair out of the resin. The coasters were covered and let dry for 24 hours.
The results:
