MasterSeal 754 SB

Post-applied FPO waterproofing membrane for below ground concrete structures

How does MasterSeal 754 SB work?

MasterSeal 754 SB is a post-applied sheet membrane in combination with the MasterSeal P 754 (Primer) waterproofing system. MasterSeal 754 is a highly flexible polyolefin membrane with self-adhesive backing. This flexible system provides a durable bond. It is created when the self-adhesive backing is completely adhered using the system primer to the correctly cleaned and prepared surface of the substructure. MasterSeal 754 SB is a cold applied and post-applied product, as it is installed without heat or open flames to existing structures.
