A crucial aspect of successful cementitious material application involves optimizing the bond between the newly applied material and the existing substrate. The question of whether to employ an intermediary bonding substance is paramount for ensuring durability and structural integrity.
Adopting a bonding agent can significantly enhance adhesion, especially when the existing surface is smooth, non-porous, or contaminated. This practice mitigates potential issues such as delamination, cracking, and premature failure of the applied cementitious layer. Historically, mechanical methods like roughening the substrate were the primary means of enhancing adhesion; however, bonding agents offer a more reliable and consistent solution, reducing reliance on labor-intensive preparation techniques.
