Product advantages

UV-resistant.
Ready to use.
Easy to apply (with brush or roller).
Excellent adhesion to any surface.
Curing with humidity in air ensures elastic and durable film.
Prevents leakage since it does not create joints.
Effective permeability to water vapor allows the surface to breathe hence preventing the moisture accumulation.
Even if membrane is damaged in any manner, the damaged part can be easily repaired in a short time.
Is resistant to water and other chemical materials.
