    ​MasterSeal Roof
    Hot Spray Applied Waterproofing Solution for all Roofs

    Hot spray systems are watertight, have excellent crack-bridging properties, are wear-resistant and have a lightweight, which makes them ideal for roof waterproofing applications. 
    Hot spray systems in the MasterSeal Roof range can be applied to all kinds of buildings and are suitable for all: 
    • Slopes: can be applied on vertical, horizontal and sloped surfaces 
    • Shapes: guarantee perfect forming in shaped surfac​es from flat to round roofs including the most unconventional shapes and green roofs
    • Weather conditions: resist a wide range of temperatures and environmental effects such as pollution and acid rain without special heavy-duty protection
    • Uses: resist all kinds of traffic and loads typical of the roof deck of a​ car park
    • Substrates: can be installed on most substrates including old concrete, build-up felt asphalt and timber substrates in both new and refurbishment projects
    • Details: allow easy detailing, creating the membrane around the details quickly without any seams, prefabricated moulded parts, mechanical fixing or additional flashings.​​

    Key benefits at a glance



    Hot spray systems are highly elastic, UV-stable and can easily be sprayed, allowing seamless waterproofing on the complex shapes of skylights, roof drains, etc.

    Fast curing

    Fast curing

    Hot spray membranes take only a few seconds to harden, allowing a very fast return to service. This means they are less dependent on weather conditions than traditional systems.



    A primer is the foundation of all systems and ensures adhesion between the protective system and the substrate.

    Chemicals and mechanical resistance

    Chemical and mechanical resistance

    Hot spray membranes are exceptionally robust and resistant to mechanical wear, abrasion and UV-stable and can be used without special protection on top.


    The membrane is the watertight and flexible layer which gives its properties to the complete system.

    Durability and maintenance costs

    Durability and maintenance costs

    Hot spray membranes are a long-lasting and very reliable solution which ensures a significant reduction in maintenance costs during the life cycle of the structures to which they are applied.


    Top coat

    The top coat has a key role and must ensure full protection against: temperature variations, sunlight, attack by deicing salts, and wheel abrasion. It has to be easy to clean and allow a fast return to service.

    Hot Spray Water tanks

    Water tanks

    Hot spray systems cope very well with the specific challenges of water storage where the water tries constantly to escape through the weakest parts of the structure.
