Fields of application

PROMASEAL® Sealants will adhere to most construction materials. Very porous surfaces may need to be wetted with clean water to prevent too rapid drying of the sealant before proper cure.  If in doubt, the sealant should be applied to a small length of joint and examined, or the Promat Technical Services Department should be contacted.  All surfaces should be clean, dry, oil, dust and grease-free and loose paint should be removed from steel.
