Abstract: The invention relates to a hand stamp adhesive applicator and method for applying a liquid adhesive to a defined area on a surface. The applicator includes a housing, an adhesive transfer stamp pad, a container, an adhesive applying stamp body, and a support mechanism for the stamp body. The housing includes a base and an upper part coupled to, and vertically displaceable with respect to, the base. The adhesive transfer stamp pad is supported in the housing and formed of a material permeable to the liquid adhesive. The container is also supported in the housing above, and in fluid communication with, the stamp pad. The adhesive applying stamp body applies the liquid adhesive to the defined area of the surface; and the support mechanism supports the adhesive applying stamp body in the housing for motion between an upwardly facing inoperative position to receive the liquid adhesive from the adhesive transfer stamp pad and a downwardly facing operative position to apply the liquid adhesive to the surface.
