Like all epoxy that you use it will have some odor. The odors will be different in each brand and can range from a light to a stronger smell. Often with an odor, it brings up the question of whether or not breathing in the epoxy resin can be a health hazard. Some customers feel as if the smell is non-existent, while it might bother some. How you interpret the smell has to do with each person’s sensitivities. It is important to know that the smell is NOT a fume or a VOC (volatile organic compound), and Promise Epoxy Resin poses no risk to your health. As with any chemical, we still want to encourage our users to work in a well-ventilated area (a large room with moving air works, as opposed to working in a small closet) and to protect your skin from the epoxy resin by wearing gloves.
