KefaSeal is a water based primer. It is recommended for use in porous, absorbent surfaces before applying KefaRid or KefaRid Spray. KefaSeal is designed for interior walls and ceilings and can be applied by brush or spray.
KefaSeal can also be used for binding loose or badly bonded asbestos material and binding asbestos dust, or after encapsulation or cleaning up, to bind possible loose fibers where it is difficult to vacuumclean 100% free from fibers.
