​Key benefits at a glance

Crack-bridging

Crack-bridging

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.

​​​MasterSeal Coating
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.

​​

Primer

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.

​

Membrane

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.
