Mak Sealing Compound [ Gr. A & Gr. B ] [ISI MARKED] A joint sealing compound must display good adhesion towards concrete and have the ability to withstand extension without cracking. It must also have a low susceptibility to flow during hot weather conditions. It should be durable and plastic, and at the same time offer resistance to ingress of solid foreign matter. The Joint Sealing Compound is heated to temperature which will permit easy pouring into the expansion joint above the joint filler. This temperature should be well below that at which the Joint Sealing Compound undergoes.
