Joint Design
The joint width must be designed to suit the movement capacity of the sealant. All joints must be properly
designed and dimensioned by the specifier and the main contractor in accordance with the relevant standards.
The basis of the calculation for the necessary joint width are the technical values of the joint sealant and the
adjacent building materials, the environmental exposure of the building, its method of construction and its
dimensions. In general, when wider than 10mmthe width to depth ratio of 2:1 must be maintained.
Method of Application
1 SURFACE PREPARATION
}}The joint surface should be sound, thoroughly clean, dry and free from grease, oil or any other contamination.
All dust and debris must be removed by wire brushing, grinding and vacuuming. Damaged joints should
berepaired using a suitable mortar from the Pidilite range.
}}Ensure that the filler material such as a closed cell polyethylene sheet or rod is tightly packed and no gaps
orvoids are evident at the base of the joint. Where backing rod is not fitted a bond breaker tape must be used.
}}Fix masking tape on both sides of joint surface to provide a neat appearance and ensure the tape is
removed immediately after tooling.
