BITUTHENE® waterproofing membranes are specifically formulated to perform as a system with BITUTHENE® accessory products, for example the BITUTHENE® System 4000 Surface Conditioner and the BITUTHENE® family of primers. Extensive research and development efforts have been undertaken to assure that all components of the BITUTHENE® waterproofing systems are chemically compatible when used according to GCP printed instructions and recommendations.
Use of non GCP primers and surface treatments along with BITUTHENE® membranes is not recommended by GCP.
Use of these may result in field compatibility problems during and after the BITUTHENE® membrane installation, to include but not limited to:
- Use of competitive primers with BITUTHENE® Membranes have been observed to cause the membrane to gradually peel off a vertical wall, even though the initial adhesion of the membrane to the primed wall appeared to be excellent.
- Long term compatibility problems may occur.
- Chemicals within other primers and surface treatments may attack the rubberized asphalt adhesive of the BITUTHENE® Membrane and lower the adhesion of the membrane to the structure, jeopardizing the performance of the waterproofing system.
