In most cases you don't need to use a sealant before applying ArtResin; however, there are some situations when sealing first makes sense: sealing over paper which may otherwise absorb the resin, sealing over loose materials that may float away in the resin, and sealing over natural objects that may off-gas, such as wood. Use a brush-on or a spray sealant that dries clear and is appropriate for your particular artwork. If in doubt, it never hurts to use a sealant first, but we always recommend doing a test on a scrap piece before you resin your masterpiece.
