Sheathing Tape for Epoxy Pours

Sheathing tape is what woodworkers use to seal a slab before an epoxy pour. Press it over the underside of cracks, splits, knots and voids and it keeps the resin from leaking through while it cures. Cured epoxy does not bond to the tape's slick surface, so it peels off cleanly afterward.

The same tape lines river table molds and forms and makes a quick dam along the edge of a slab or tabletop. This is Tuck Tape contractors sheathing tape, the same tape we use in our own shop.
