Polyflex MS
Next-generation waterproofing technology, built for performance and reliability.
Polyflex MS
Polyflex MS is a high-performance roof membrane developed using advanced Japanese MS Polymer technology. Unlike traditional polyurethane, silicone, bitumen, or cement–acrylic coatings, Polyflex MS offers a safer, stronger, and more flexible solution for long-lasting waterproofing across a wide variety of applications.
This innovative liquid-applied system has become the roofer’s number one choice for flat roofs, balconies, terraces, and detailing work, thanks to its combination of durability, ease of application, and proven results.
Why Choose Polyflex MS?
Polyflex MS has been engineered to solve many of the common issues roofers face on-site. Its solvent- and isocyanate-free composition makes it safe for both installers and the environment, while its 100% elastomeric structure ensures it will not shrink or crack over time.
Key advantages include:
- Outstanding flexibility and durability – bridges cracks up to 3mm and withstands building movement without splitting.
- UV and weather resistance – resists yellowing, cracking, and sagging, even under prolonged sunlight.
- Primerless adhesion – bonds securely to a wide range of substrates including bitumen, concrete, timber, metal, stone, brick, glass, and ceramics – even on damp surfaces.
- Seamless, self-levelling finish – eliminates weak points associated with laps and joints.
- Quick curing – rainproof in just 30 minutes, with full curing in 7 days.
- Safe and user-friendly – almost odourless, solvent-free, and low VOC for use in sensitive environments.
Application Areas
Polyflex MS is designed for both new build and refurbishment projects across residential, commercial, and industrial settings. Thanks to its versatility, it can be applied to both horizontal and vertical surfaces with ease, using a brush, roller, or trowel.
Typical applications include:
- Balconies, terraces, and pitched roofs
- Waterproofing around chimneys, skylights, and ventilation details
- Wet rooms, bathrooms, and kitchens
- Basements, garages, and foundations (non-pressurised water)
- Localised repairs or complete roof overlays
With no reinforcement required for areas up to 100m², Polyflex MS is a practical and efficient choice for contractors looking to save time without compromising on performance.
Easy Application
Polyflex MS is supplied as a ready-to-use, single-component system – no mixing, priming (in most cases), or dilution required. Simply pour, spread, and allow it to level.
For best results:
- Apply in two coats, perpendicular to each other
- Allow 6–12 hours between applications
- Use reinforcing mesh on areas above 100m²
- Protect from rain, dew, or frost until dry
A smooth, seamless, and durable waterproof layer can be achieved with minimal effort, making Polyflex MS a contractor-friendly system.
