Martin's Frisket Mask Liquid is a safer liquid frisket that lets you mask out areas of paper, photos, and other media you want to remain pristine while overlaying applications of color.
Waterbased and AP certified non-toxic, it conforms to ASTM D-4236.
When dry, simply remove the frisket by peeling or rubbing it with a soft eraser.
It seals well on almost any surface, does not stain, and peels off cleanly without tearing or removing the sizing from paper.
The bottle includes an eyedropper lid for easy application.
