Mortar bonding additives are typically formulated from a blend of polymers, resins, and other chemical agents that improve the bond strength between the mortar and the substrates. These additives can be classified into two primary categories polymer-based and chemical additives. Polymer-based additives, often in the form of emulsions or powders, enhance the flexibility and workability of the mortar, allowing it to better accommodate slight movements in the building materials. Chemical additives, on the other hand, may include fortifying agents that improve water retention and enhance adhesion properties.
