The Laurenco PMMA System is a multi-layered waterproofing and roofing assembly consisting of a universal primer, high-quality PMMA resins, and fleece reinforcement. The system utilizes pre-measured gel catalyst packs that simplify mixing and significantly improve jobsite safety by eliminating the need to handle and measure loose powdered catalysts. Laurenco PMMA Systems are designed for year-round application, with working temperatures ranging from 20°F to 122°F. PMMA resins are available in both horizontal and flashing grades, allowing for precise detailing and efficient installation. The system is compatible with a wide variety of substrates, including new and existing concrete, wood, plywood, metal, masonry, and more. ### Download the PMMA Systems Installation Guide Learn more about our durable, easy-to-use PMMA waterproofing system designed for reliable performance and efficient installation [DOWNLOAD](https://www.laurencowaterproofing.com/hubfs/Technical%20Documentation/PMMA-Installation-Guide-001-rev-06-1.pdf?hsLang=en) products ## PMAA Products \[6\] Built from proven materials that work together ![](https://www.laurencowaterproofing.com/hubfs/BLUE-1.png) BLUE PMMA UNIVERSAL PRIMER ![fleece](https://www.laurencowaterproofing.com/hubfs/fleece.png) LAURENCO FLEECE ![](https://www.laurencowaterproofing.com/hubfs/catalyst.png) PMMA CATALYST ![](https://www.laurencowaterproofing.com/hubfs/PMMA-PRR.png) PMMA PRR ![FLASHING](https://www.laurencowaterproofing.com/hubfs/pmma-flashing.png) PMMA FLASHING RESIN ![PMMA-H](https://www.laurencowaterproofing.com/hubfs/PMMA-H.png) PMMA-H RESIN ### Laurenco’s PMMA System is designed with the contractor’s safety and ease of application in mind. From the initial primer through the final protective layer, the Laurenco PMMA System has become a preferred waterproofing and roofing solution among contractors. The Universal Blue PMMA Primer enhances visibility during application, allowing for more accurate coverage and more thorough inspections. A controlled “snap-cure” formulation provides sufficient working time for proper placement and detailing before rapid cure. The Laurenco PMMA System may be used as a standalone waterproofing solution or integrated into the Laurenco RMA System to provide enhanced composite waterproofing performance. Pre-measured Laurenco PMMA gel catalyst packs improve jobsite safety and consistency by eliminating the need to handle loose powdered catalysts. This simplified activation process reduces mixing errors, saves time, and supports reliable system performance.
