Abstract: Pads for posting removable adhesive sheets capable of receiving markings are disclosed. The pads comprise a stack of a plurality of adhesive sheets having release sheets adhered to the back of each, wherein each adhesive sheet, when applied to a surface, is removable without leaving an adhesive residue. The adhesive sheets comprise a flexible polymer film, polymer-reinforced sheet or cloth having a Taber stiffness of not less than 0.03 measured according to ASTM D747, a front side capable of receiving markings and a back side substantially covered with a pressure sensitive adhesive having an initial tack value of at least 200 g measured according to ASTM D2979 on a Polyken.TM. probe tack tester, an adhesive tack sufficient to prevent conformability failure of the adhesive sheet after 10 hours conformability testing, and an adhesive strength of at least 100N/m according to ASTM D1000 and each release sheet covers at least 50 percent of the pressure sensitive adhesive on the back of each adhesive sheet.
