Suman Refractory produces a wide range of fireclay and high alumina mortars. These mortars are used as jointing materials for various fireclay and high alumina bricks. Mortars, suitable for different types of insulation bricks, are also manufactured by us. Some of the mortars are supplied as two component system, where liquid binder is separately provided with powder material. In such case, liquid component should be used only as per our recommendation. Where water is used as liquid component, the amount of water used should be such that it results in trowelling consistency.
