Selofalt is a two pack anti-skid protective surfacing material used to increase durability and improve safety on standard asphalt or concrete pavements. The product especially protects bituminous pavements against external aggressive substances that may spill on its surface such as oil, gasoline, hydraulic fluid, organic solvents and compounds, most chemicals and corrosive materials, etc.

Supplied in a two-pack kit in liquid form, the product must be mixed right before application onto the pavement. Selofalt is applied by airless spray or rollers directly on the surface of the pavement in one or more layers and may incorporate coarse abrasive grit material to provide ultimate anti-skid conditions.

Selofalt works by penetrating the surface of the asphalt and chemically reacting to the existing bituminous binder, modifying it and forming a polymeric protective shied chemically bound to the pavement.

Critical areas of bituminous pavements treated with Selofalt have shown from 300 to 500% extended lifetime compared with similar non-treated areas.

The exclusive high-volume bus corridor located in the City of Sao Paulo in Brazil was treated by using yellow Selofalt. Three years later the new bituminous pavement covered with Selofalt did not present any sign of “plastic deformation”, which commonly occurs after one year of use, due to the penetration of oil and petroleum derivatives that commonly leak from the buses. Additionally, around 94% of the yellow surfacing anti-skid film of Selofalt remained preserved.
