The glue is activated by moistening. After drying, good and permanent adhesion (adhesive strength) is acquired. In comparison to self-adhesive tapes, removable if re-moistened with water. To detach the surface of the tape, moisten it for 5 – 10 minutes and then peel it off carefully.
Please ensure while moistening the paper tape, that the gummed side of the tape is moistened evenly, using either a wet sponge or a humidifier. Do not moisture excessively! The gummed side can easily be recognized by comparing the front and back side, the gummed side is slightly yellowish in colour. Please prevent immersing the paper tape completely into the water bowl because in this case the glue releases itself from the paper tape. Experience has proven that the most effective moistening method is by using a plastic bowl filled with sponge and with the top section also covered with a sponge cloth. Please note that the ultimate adhensive strength is only achieved after complete drying of the adhesive bond.
