When applied to paper that is destined to go under ICE Resin, this paper sealant will maintain its opacity, instead of becoming transparent, as paper does under ICE Resin. It is quick drying: just paint it on with a sponge and hold it in the air for 30 seconds to a minute; then apply ICE Resin (sold separately), as usual, and insert it into a bezel that is ready for an ICE Resin pour. The use of Paper Sealant is for those special cases where you want to keep very dark, graphic lines in your collage work, or when using actual photographs, which can have a mottled look under resin because of uneven emulsion. Each package includes one 2 ounce bottle.
