Keep your veneer edges tight while inside the press with Gummed Veneer Tape! Includes a 650 foot long roll of white 34 gram cellulose tape that measures 3/4" wide. Apply it to your joint, then as it dries, it shrinks. This shrinking action helps to hold the seam together while in the press. Perforated with a three hole pattern for ease of use, and it lets you see the seam under the tape which allows for adjusting/tightening of the seam before the tape dries.
