EASY APPLICATION WITH DURABLE RESULTS

The Laurenco PMMA System is designed for use in roofing and waterproofing applications not subjected to vehicle traffic.

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.

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.

Features & Benefits

Features & benefits

The Laurenco PMMA System provides a high-performance waterproofing solution that is efficient to apply, highly durable, and engineered for safe installation and use.

MADE IN THE USA

Laurenco PMMA System components are manufactured in the United States and readily available to help keep project timelines on schedule.

BLUE PRIMER

Laurenco Universal BLUE Primer incorporates a blue tint to improve visual coverage verification, simplifying inspections and allowing applicators to easily identify underapplied areas.

USE ALL SEASON LONG

The Laurenco PMMA System is engineered for application in temperatures from 20°F to 120°F, enabling year-round installation in most climates and supporting accelerated project schedules.

USE AS A STAND-ALONE OR COMBINED SYSTEM

The Laurenco PMMA System is engineered for standalone roofing and waterproofing or integration into the Laurenco RMA System as a composite assembly, offering flexibility for varying project requirements and conditions.
