    Hydrolastic AP560 liquid applied hybrid polyurethane waterproofing roof coating by MATEX

    Hydrolastic Ap560

    Liquid Applied Hybrid Polyurethane Modified Waterproofing Coating

    HYDROLASTIC AP560 is a cold-applied, one-component hybrid elastomeric waterproofing roof coating based on advanced polyurethane dispersion technology. Designed for tropical climates, it forms a highly elastic, seamless membrane offering outstanding protection against moisture and standing water. HYDROLASTIC AP560 is VOC compliant, non-toxic, and highly UV resistant, with excellent strength, elasticity, and low water uptake. It withstands extreme temperature fluctuations, resists ponded water conditions, and provides superior crack bridging. White roof applications can help reduce interior heat, improving energy efficiency. This flexible, high-performance membrane delivers exceptional durability even under low-temperature conditions.

    How to Apply Hydrolastic Ap560

    Hydrolastic AP560 is applied cold in a minimum of two coats over a prepared, primed substrate.

    1. Prepare the substrate. Clean and prepare all substrates by high pressure water jet, abrasive blast cleaning, scarifying or other approved mechanical methods. Concrete must be sound, clean, dry, cured for at least 28 days and have a moisture content not exceeding 5%; repair voids and blow holes with MATEX concrete repair products and remove mold, mildew and fungus.
    2. Prepare other substrates. Brick and stone mortar joints must be sound and flush pointed. Bituminous felt should be cleaned with high pressure water; metals abraded to bright steel and primed immediately; existing paints must be sound, with oxidized layers removed.
    3. Prime. Prime porous substrates with Hydrolastic AP560 diluted with 10% water. On non-porous substrates apply one coat of Armoprime WB.
    4. Mix. Stir properly with a slow speed mixer to a homogeneous mix, avoiding over mixing to minimize air entrapment. Do not thin the product.
    5. Apply the coats. Apply a minimum of 2 coats, making sure each coat is completely dry before the next (6–8 hrs at 25°C). Total thickness must not be less than 0.5 mm dft.
    6. Reinforce critical points. For additional mechanical strength over the whole surface or at joints, wall junctions, vent pipes and similar details, embed a layer of geotextile membrane between the two coats.
    7. Protect and clean. Avoid ponding water for a minimum of 72 hours after application. Clean tools with water immediately after use; cured material can only be removed mechanically.

    Frequently Asked Questions

    What is the coverage of Hydrolastic AP560?

    One 20 kg unit covers approximately 7.5–8.0 m² at 1.0 mm dry film thickness, applied in a minimum of 2 coats. Total thickness must not be less than 0.5 mm dft.

    What is the drying time between coats of Hydrolastic AP560?

    Each coat must be completely dry before the next is applied, which takes 6–8 hours at 25°C. Ponding water should be avoided for a minimum of 72 hours after application.

    What temperatures can Hydrolastic AP560 be applied and used at?

    Ambient air and substrate temperature must be +8°C to +40°C with relative humidity of 80% max, and the surface must be at least +3°C above the dew point. Service temperature is -5°C to +80°C.

    Can Hydrolastic AP560 be used for ponded water or immersion?

    The TDS lists resistance to ponded water conditions, but states it should not be subjected to permanent water immersion.

    Is Hydrolastic AP560 a reflective roof coating?

    Yes. It is a white coating with a Solar Reflection Index above 90 (E1980), and the TDS lists conformance with LEED SS Credit 7.2 (SRI > 78) and reflectivity requirements of Estidama and Dubai Green Buildings.
