Why I Use ArtResin
I love using ArtResin on all of my fluid art paintings and coasters. It provides a beautifully smooth, glass-like finish, enhances metallic paint and really makes colors pop. It has no VOCs or fumes, so I can safely use it indoors, and it is food safe. Although there is a learning curve, it is easy to use, with a 1-1 ratio of an epoxy resin/hardner. ArtResin also has a great e-book tutorial and a lot of excellent instructional videos on their website. While it is expensive, the ease of use and the quality of the results make it well worth the price.
For best results, I strongly recommend using the product in an enclosed room with an air purifier that you run regularly to reduce the dust and hairs in the air, and to cover the piece with a clean box while the ArtResin cures. I have also found that it is important to make sure the room temperature stays above 70°F/21°C while the resin cures, so where I live I need to use a heater in the winter. It is best to get a space heater that radiates heat rather than blows hot air, so that you don't add more particles to the air that can land on the resin before you cover it. Something I learned the hard way is that it is best to work on wood rather than canvas, because while you can resin canvas, you have to take extra measures to make sure the canvas doesn't sag in the middle with the weight of the resin. Working on wood avoids this problem entirely.
Perhaps the best part about working with ArtResin is that it is very forgiving. If there is a flaw in the finish, all you have to do is lightly sand the surface of the piece once it is fully cured to give it some grit (making sure you do not sand through to the paint), clean the surface with a damp towel, wait for it to dry, and then pour another layer. I personally prefer the finish with two layers of ArtResin so I do this regularly.
