Why choose MPM liquid waterproofing?

The question "Why choose liquid waterproofing?" frequently arises during the planning of new builds as well as construction and rehabilitation projects. The answer lies in the ability of cold-applied liquid membranes to create a 100% continuous elastomeric layer—free of joints, overlaps, or seams vulnerable to water ingress. Unlike traditional bituminous membrane systems, which require open-flame torches and pose high risks around complex details, liquid waterproofing adheres continuously and fully to the substrate, perfectly sealing gutters, pipes, skylights, and internal corners (skirtings).

Key Reasons to Choose Liquid Waterproofing:

1. Cold Application and Job-Site Safety: Completely eliminates fire hazards by avoiding open flames, a critical factor when rehabilitating occupied buildings, industrial sites, or timber structures.
2. Continuous, Seamless Membrane: Perfectly molds to any geometry and critical point across roofs, terraces, parking decks, or swimming pools, preventing leaks caused by joint-adhesion failures.
3. High Elasticity and Movement Accommodation: Absorbs the substrate's thermal expansion and contraction, maintaining crack-bridging capabilities even under extreme temperatures.
4. Multi-Substrate Adhesion: Allows direct application onto concrete, ceramics, metal, timber, or over existing bituminous membranes, reducing demolition costs and labor time.

MPM STARFLEX Range: Innovation Serving Construction
As the official distributor for MPM in Portugal, Nacionalrev offers the STARFLEX range, engineered to address every technical requirement:

• STARFLEX ULTRA: Ultra-high-performance polyurea-based system designed for thick, single-coat application. Features exceptional UV resistance with an optional BRoof exterior fire rating certification.
• STARFLEX HR-M: Two-component, elastic, self-leveling polyurea membrane engineered for surfaces subjected to pedestrian and vehicular traffic. Offers high resistance to abrasion, puncturing, and chemicals—making it the perfect solution for parking garages, balconies, and driveable roof decks.
• STARFLEX HYBRID: The only liquid waterproofing membrane in its class capable of being applied directly over wet and damp substrates without requiring a primer. Starflex Hybrid extends the working season year-round, eliminating weather-related project delays and reducing downtime.
• STARFLEX MONO: Highly flexible, durable liquid polyurethane membrane ideal for waterproofing and rehabilitating roofs and terraces. Certified for asbestos encapsulation when applied as a complete system.
• STARFLEX C: Two-component elastic cementitious mortar engineered for continuous waterproofing on new and existing substrates. Ideal when a mineral-based system is required (under-tile applications on flat roofs, wet areas, swimming pools, and foundations), delivering high crack-bridging elasticity and rapid curing, even in cold or humid conditions.
• STARFLEX T: Solvent-free, single-component transparent elastic coating. Specially developed for the transparent waterproofing and protection of terraces, balconies, ceramics, tiles, or polycarbonate surfaces without requiring demolition or removal of existing flooring. UV-resistant (non-yellowing), water-vapor permeable, and suitable for light foot traffic.
