MYK ARMENT AQUA ARM SPU SPL (GREEN) WATERPROOF COATING

About MYK ARMENT AQUA ARM SPU SPL (GREEN) WATERPROOF COATING

 91 000 74051 AquaArm SPU SPL A single-component, high-performance, bitumen-free, polyurethane waterproofing coating. It is moisture-cured, meaning it reacts with humidity in the air to form a highly elastic, seamless, and durable membrane.
Primary Function: To provide a robust, flexible, and chemical-resistant waterproofing barrier for critical areas, both above and below ground, where a high-quality, non-bituminous solution is required.
Key Features & Benefits (from TDS):Bitumen-Free & High Performance: Offers superior elasticity and longevity compared to many modified-bitumen products.High Elasticity: Exceptional elongation (500%) to bridge dynamic cracks (2mm).Excellent Adhesion: Strong peel adhesion to concrete (2.0 N/mm).Durable: Resistant to hydrostatic pressure, punctures, tears, and chemical ingress.Environmentally-Friendly: Non-toxic once cured.Single Component: Ready to use; no on-site mixing required, ensuring consistent quality.
Q1: How is this different from other waterproofing coatings?A: Its key differentiator is that it is a high-performance, bitumen-free polyurethane. This gives it better elasticity, durability, and environmental credentials compared to bitumen-based or acrylic coatings. It is also single-component, unlike 2-part PU systems.Q2: What is the application process?A:Surface Prep: Concrete must be strong, smooth, clean, and dry (moisture <5%). All corners must be rounded (50mm internal, 10mm external).Priming: It is mandatory to apply FloArm Primer PUDC on the prepared surface.Application: Apply the first coat of SPU SPL. Apply the second coat after approx. 12 hours (at 28C) in a direction perpendicular to the first.Protection: The membrane must be protected with a screed or suitable covering.Q3: What is the coverage area?A: The theoretical consumption is 1.5 kg per square meter to achieve a 1mm Dry Film Thickness (DFT). Actual consumption will depend on surface porosity and roughness.Q4: How long does it take to dry and cure?A:Surface Dry: 12 hoursFully Dry: 24 hoursRecoat Time: 12 hours (at 28C)Water Test: Can be performed only after the membrane is fully cured.Q5: What is the shelf life and how should it be stored?A: The shelf life is 6 months from the date of manufacture. It has very specific storage requirements:Store in a cool, dry, moisture-free, shaded place.Transport and store the pails upside down (inverted position) to prevent skin formation.Once opened, the material must be used within 30 minutes.Q6: What are the critical limitations?A:Not root resistant.Do not apply on damp surfaces or if temperatures are below 5C.Avoid application in rain, snow, or sandstorms.The opened pack has a very short application life of 3 hours if resealed.Protect the applied membrane from direct sunlight during peak summer heat.Q7: Is it safe to use?A: Standard chemical safety precautions are necessary:The storage and work area must be well-ventilated.Operators must wear a safety helmet, gloves, and protective shoes.Avoid contact with eyes and skin.Keep aay from fire and ignition sources.

Superior Waterproofing Performance

AQUA ARM SPU SPL GREEN delivers seamless, high-performance waterproofing with outstanding crack bridging and resistance to UV degradation. Its robust elastic membrane effectively prevents water ingress on surfaces exposed to severe weather or standing water. This ensures long-lasting protection for structures, reducing maintenance and repair costs over time.


Fast Curing and Simple Application

With a touch dry time of only 2-4 hours and full cure in just 7 days at 25C, this single-component system offers quick project turnaround. Application is easy and flexible-you can use a brush, roller, or spray, adapting to any job site. Recoating is possible within 4-6 hours, making it efficient for multi-coat systems.


Highly Versatile for Multiple Uses

AQUA ARM SPU SPL GREEN is suitable for a broad range of surfaces, including concrete and masonry. Its remarkable adhesion (>1.0 N/mm2), high tensile strength, and durable, seamless finish make it ideal for rooftops, balconies, wet rooms, tanks, planters, and more. The product is usable in a wide service temperature range (-10C to +80C), ensuring year-round reliability.
