It is recommended that the alignment of the masonry surface and concrete should be as straight as possible. This will result in the use of minimum material for maximum coverage and output hence minimizing the cost and time used in execution.
Prior to the application of Ressi PlastoRend 120 C it is recommended that all the joints between masonry and concrete surfaces are treated with an appropriate method like a wire metal mesh between the RCC and masonry joint. There are several joint sealants (Cement compatible) that can also be used for this application.
