Suitability and pre-treatment of surfaces
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.
Durability of sealants under normal weather circumstances can vary from 5 to more than 30 years, depending the type. This means with good functioning and application of the sealant, replacement is only mandatory after several years. In this period, in...Read more
