When it comes to achieving the perfect application within flat roofing environments, on many occasions it is important for installers to use a primer when preparing the surface upon which the waterproofing membrane will be applied. This can help optimise your installation and ensure compatibility with various substrates, reducing the risk of any problems arising after the project has been completed. In this article we delve into five reasons why you should prime.
Enhanced Adhesion
Applying a primer to the roof area prior to the application of the waterproofing system, will ensure that the membrane is sufficiently bonded for many substrates. This in effect reduces the risk of delamination from occurring and will enhance the overall adhesion strength between the substrate and the waterproofing system, helping you to achieve a robust finish that will serve to protect the building for many years to come.
Vast Compatibility
Incorporating a primer into the installation process of your liquid membrane can significantly influence its compatibility with different substrates. Owing to the large range of primers available through Polyroof, this equips installers with enhanced versatility, as the waterproofing systems can be bonded to many substrates that other conventional systems cannot, including preexisting liquid membranes, bitumen, and single ply. This reduces the need to remove substrates prior to application, which in turn reduces waste on site.
Barrier Against Unstable Substrates
Many roof substrates, especially bituminous ones, can deteriorate over time. This can present significant risk to the integrity of the waterproofing system and the overall roof area, should the installer negate to prime the roof area. By incorporating a barrier primer into the application process, this will provide added protection to the liquid-applied membrane from substrate deficiencies and instability throughout the lifespan of the system.
Better Coverage
Another benefit of using a primer in conjunction with your liquid applied membrane, is the better coverage that you can achieve across the roof area. By sealing the surface, the primer subsequently minimises resin wastage, therefore, achieving a more seamless, more cost-effective application.
Improves Aesthetic Finish
Applying a primer in conjunction with your liquid applied membrane will enable you to enhance the overall aesthetics of the flat roof, resulting in a sleeker, more appealing finish. This is particularly beneficial for projects where your client requires a high-end, aesthetically pleasing roof.
