In the demanding world of construction and roofing, finding a waterproofing solution that combines long-term durability, ease of application, and exceptional weather resistance—especially for fully exposed surfaces—is a constant challenge. Meet Aquaseal 305 Water-based Rubberized Waterproof Coating (Exposed), a technological leap in protective coatings designed to deliver unparalleled performance where it matters most.
What is Aquaseal 305?
Aquaseal 305 is a premium-grade, ready-to-use, single-component elastomeric coating. Formulated with high-quality rubber polymers and resins, it cures to form a seamless, flexible, and rubber-like membrane directly on the substrate. Its key distinction is its formulation for exposed applications, meaning it requires no protective topping or covering layer, making it an efficient and cost-effective choice for a wide range of waterproofing and repair projects.

Unmatched Product Advantages for Lasting Protection
1.Superior Long-Term Weather & UV Resistance:Engineered to withstand harsh environmental stressors, Aquaseal 305 offers excellent UV aging resistance. It reflects solar radiation and maintains its integrity, preventing the common issues of cracking, embrittlement, and fading that plague inferior coatings. It is designed to perform in exposed conditions for 5 years and beyond, providing reliable, long-lasting protection.
2.Exceptional Flexibility & Elasticity:The advanced rubberized formula grants the cured membrane outstanding elasticity. It can bridge existing hairline cracks and accommodate natural substrate movement due to thermal expansion and contraction, ensuring a continuous, seamless barrier that prevents water ingress.
3.Durable & Light-Trafficable Surface:Unlike many liquid coatings, Aquaseal 305 cures to form a wear-resistant and light-trafficable This makes it ideal for roof terraces, balconies, walkways, and other areas that may require occasional foot traffic for maintenance, without compromising the waterproofing layer.
4.Eco-Friendly & User-Friendly Application: As a water-based product, Aquaseal 305 features low VOC content, ensuring a safer environment for applicators and building occupants.

·Application Rate:Approximately 0.75 kg/m² per coat.
·Coverage Guide:
5 kg Pail: Covers 3 m² to 4 m² (based on 2-3 coats).
20 kg Pail: Covers 12 m² to 16 m² (based on 2-3 coats).
Professional Note: The provided data is based on standard laboratory conditions and is for reference. Actual consumption must be calculated based on the specific porosity, texture, and condition of the onsite substrate.
Professional Construction Procedures
To guarantee maximum performance and lifespan, follow these key steps:
1.Surface Preparation: The substrate must be clean, sound, dry, and free of dust, oil, grease, and loose particles. Proper preparation is critical for adhesion.
2.Primer Application (001 Primer): Apply the recommended primer to enhance bonding, especially on porous or specific substrates.
3.Detail & Node Enhancement: Reinforce critical areas such as drains, corners, cracks, and penetrations with additional coating and embedded non-woven fabric.
4.Base Coat Application: Apply the first full coat of Aquaseal 305 evenly over the prepared surface.
5.Subsequent Coats with Reinforcement: Apply the 2nd and 3rd coats, typically embedding a layer of non-woven fabric between coats for added tensile strength and crack-bridging capability, as per design requirements.
6.Curing & Protection: Allow sufficient time for the coating to cure fully before subjecting it to traffic or water exposure. Protect from rain during application and initial curing.
