For an optimal functioning of a sealant joint it is of essential concern that the sealant will make a good bonding on the surface it is applicated to. Indeed if the bonding fails, the function of sealing partly fails. The strength of bonding between sealant and surface depends to: 1 Strength of surface. 2 Suitability of surface. 3 Pre-treatment of surface. 4 Situation of surface during application. 5 Tolerance of surface with the sealant applied. 6 Application of bonding primer. Furthermore, it is of course important that the sealant is applied in the correct manner.
