Neoproof PU Fiber

Neoproof PU Fiber is a fiber-reinforced, water-based polyurethane waterproofing coating designed for exposed roofs requiring enhanced crack-bridging performance, durability, and resistance to standing water. It forms a thicker, elastic membrane ideal for both full-surface application and detailing in complex roof areas.


Suitable Applications

▪ Exposed roofs constructed with concrete, cement tiles, or cementitious screeds
▪ Walkable roofs requiring high resistance to ponding water
▪ Metallic roof surfaces with appropriate priming
▪ Application over new or existing liquid waterproofing systems
▪ Installation over mineral bitumen membranes
▪ Local detailing around pipes, gutters, chimneys, and roof penetrations

Description

Fiber-Reinforced Polyurethane Waterproofing for Enhanced Roof Protection

Neoproof PU Fiber is a one-component, water-based polyurethane elastomeric waterproofing coating reinforced with fibers to deliver improved membrane thickness, durability, and crack-bridging performance. It is specifically developed for exposed roof applications where standard coatings may not provide sufficient strength or flexibility.

The system cures to form a seamless, moisture-impermeable membrane that protects roof substrates from water ingress, UV radiation, and environmental stress. Its fiber-reinforced structure enhances resistance to movement and surface irregularities, making it particularly suitable for roofs with minor cracks, uneven substrates, or areas requiring localized reinforcement.

At Everkast, this system is recommended for projects where additional reinforcement, durability, and long-term waterproofing reliability are required — especially under Nigerian climate conditions involving heavy rainfall, intense sunlight, and thermal movement.

Neoproof PU Fiber can be applied across entire roof surfaces or used for detailing in critical areas such as around penetrations, drainage points, and joints. It is also compatible with other water-based waterproofing systems, making it suitable for refurbishment and repair of existing coatings.
