Bostik Cementone Flexacryl Roof Coating Black 5kg – 30811957

Bostik Cementone Flexacryl Roof Coating is a high-performance, fibre-reinforced waterproofing compound designed for fast, effective repair and protection of roofs. Ready to use straight from the tin, this durable coating forms an instant waterproof seal, making it ideal for general roof maintenance and repair work.

Product Features/Specifications:

This premium black roof coating features a thick, brush-on formulation packed with fibres for added strength and crack-bridging capability. Designed to bond securely to most roofing substrates, it delivers long-lasting weatherproof protection with excellent resistance to standing water.

Detailed Product Benefits:

The Flexacryl formula provides exceptional elasticity, allowing the coating to accommodate structural movement and temperature changes without splitting or peeling. Its fibre-reinforced composition enables it to fill and bridge gaps, ensuring a seamless and robust protective layer. Because it cures quickly—even on damp surfaces—Flexacryl offers reliable waterproofing in unpredictable weather, significantly reducing downtime for repairs. Once applied, it forms a tough, weather-resilient membrane that extends the lifespan of roofs and prevents water ingress in vulnerable areas.

Applications and Versatility:

Suitable for a variety of roofing materials, including roofing felt, asphalt, bitumen, cement, metal, and more, Bostik Cementone Flexacryl is ideal for both emergency patch repairs and planned maintenance. It can be applied to flat roofs, pitched roofs, gutters, flashings, upstands, and other exposed areas requiring immediate waterproofing. Its deep black finish provides a neat, uniform appearance while enhancing surface durability and weather resistance.
