Adhesion Inhibitors4.1 GeneralAmong the items that inhibit the initial adhe-sion of membrane waterproofing
21、 systems are form releaseagents, concrete curing compounds, admixtures, laitance, con-crete surfacing compounds, grease or oils, moisture, and forsome membrane types, surface roughness of the concrete.4.2 Form release agents, such as oil, grease, wax, andsilicones, will transfer from the forms to th
22、e surface of theconcrete during casting. These can cause poor adhesion ofwaterproofing systems. Since these agents are almost invisible,it is difficult to detect their presence. Any procedure for theremoval of such materials will be specific to that material.Proprietary form coating materials should
23、 be accepted prior touse and after evaluation by the specifier to determine that theyare appropriate for use with the proposed waterproofingmaterials and systems. Proprietary paint systems applied to theforms that are non-transferable and formulated to preventcontamination of the concrete surface sh
24、ould be used wheneverpossible.4.3 Concrete curing compounds may contain waxes, resins,chlorinated rubber, or film formers of various types. If suchmaterials must be used, the specifier should be certain that thematerials can be completely removed or that the waterproofingsystem manufacturer has eval
