Polyurethane Roof Coating

Polyurethane roof coatings provide a seamless, fully bonded waterproofing solution for flat roofs. Applied as a liquid membrane, these systems cure to form a durable, flexible layer that protects against water ingress, UV exposure and general weathering.

Suitable for both refurbishment and repair applications, polyurethane coatings are commonly used on existing felt, asphalt, concrete and timber substrates where a cold-applied, joint-free system is required.

Vanquish Systems offers a practical, trade-focused approach to liquid waterproofing, with products designed for straightforward application and reliable long-term performance.

A typical polyurethane waterproofing system normally relies on suitable substrate preparation, primer where required, and a liquid-applied polyurethane coating. Some liquid systems require separate reinforcement to be embedded during application, particularly at details, joints and high-risk areas.

Vanquish Fibre PU simplifies this process by incorporating fibre reinforcement within the coating itself, helping reduce application steps and improve installation speed while still providing a seamless, reinforced waterproofing layer.

Each system should be installed to the relevant product guidance, with suitable preparation, priming and detailing carried out where required.


Polyurethane Roof Coating - Vanquish Fibre-PU
Vanquish Fibre PU is a fibre-reinforced polyurethane roof coating suitable for flat roof waterproofing and repair applications. The reinforcement is pre-embedded within the coating, reducing the need for separate matting in many standard applications and helping speed up installation. Applied by brush or roller, it forms a seamless, fully bonded waterproofing membrane.

Polyurethane Roof Primer - Vanquish PU-Prep
Vanquish PU Prep is a high-performance polyurethane primer used to prepare substrates prior to coating application, promoting adhesion and improving system performance.
