Sika launches Sikalastic Rapid PMMA for flashing and roofing

Sika Corporation’s Roofing & Waterproofing division has introduced Sikalastic Rapid PMMA, a unified PMMA line for flashing and field membrane applications. The launch is designed to give contractors and owners a single system with faster installation, broader compatibility and more finish options for demanding roofing and waterproofing projects.

Why it matters: - Sikalastic Rapid PMMA combines flashing and field-applied PMMA solutions under one brand, which can simplify product selection for roofing and waterproofing projects. - The line is designed to support faster installations, broader application flexibility and long-term protection in exposed building areas. - The launch also expands options for contractors working in complex details and for owners who want both performance and finished appearance.

What happened: - Sika Corporation – Roofing & Waterproofing introduced Sikalastic Rapid PMMA on July 1, 2026. - The new brand covers PMMA solutions for both flashing applications and field membrane applications. - The flashing product is Sikalastic Rapid-724. - The roofing and waterproofing field membrane product is Sikalastic Rapid-723. - Sikalastic Rapid PMMA is a two-component, fast-curing liquid resin system.

The details: - The system creates a seamless, fully reinforced waterproofing membrane. - Catalyst is added to the resin to activate the chemical curing process. - Fleece reinforcement is used to form a monolithic, self-flashing and self-adhering reinforced membrane. - In flashing applications, the product is positioned for complex penetration details and irregular shapes. - The flashing system is intended to provide a cleaner finished appearance in tight clearances. - As a field-applied solution, the product is designed for amenity decks, balconies, terraces and other exposed surfaces. - The line offers color options and slip-resistant finishes for occupied spaces. - The product portfolio also supports planters, fountains, pools, pedestrian traffic systems, under pavers and complex detailing conditions.

Between the lines: - The move to a unified brand suggests Sika is trying to make its PMMA offering easier to specify and use across more project types. - The emphasis on compatibility and broader application coverage points to a push for more complete roofing and waterproofing systems rather than standalone products. - William Bellico, vice president of marketing, said the launch is a significant step forward in how Sika delivers PMMA systems and performance.
