SRS PU Fibre is a ready-reinforced, one-component polyurethane waterproof coating designed for precision detailing and reliable repairs. As part of the SRS range of advanced liquid roofing systems, PU Fibre combines thixotropic properties with elastomeric flexibility to deliver a seamless, durable, and highly adaptable waterproofing solution.

This fibre-reinforced liquid polyurethane is particularly effective for localised applications around complex details such as pipes, upstands, skylight bases, and gutters – areas where traditional membranes often fail. By incorporating reinforcing fibres directly into the formula, PU Fibre provides added thickness, strength, and crack-bridging performance in a single coat.

Key Advantages of SRS PU Fibre

• Fibre-reinforced formula – built-in fibres simplify installation by eliminating the need for additional sheet reinforcement.
• Seamless and durable – delivers long-lasting waterproofing protection in one application.
• Thixotropic properties – minimises sagging on vertical surfaces and complex details.
• Elastomeric flexibility – accommodates structural movement without cracking or compromising the waterproof seal.
• Fast curing – rain resistant within 30 minutes and ready to overcoat in around 2 hours.
• Single-component convenience – no mixing required, reducing time and application errors.

Application Guidelines

• Surface preparation: Ensure surfaces are clean, dry, and free of contaminants. Repair or prime as required according to technical datasheets.
• Application: Stir well before use to evenly distribute fibres. Apply by brush or roller to suit project requirements.
• Curing: Resistant to rain within 30 minutes; ready for overcoating in approximately 2 hours (subject to temperature and humidity).

Packaging and Coverage

• Available sizes: 2.5kg, 5kg, and 10kg containers.
• Coverage rate: 1.5–1.8 kg/m².
