Bostik Cementone Flexacryl Grey Roof Coating 2.5kg 30811945

The Bostik Cementone Flexacryl Grey Roof Coating 2.5kg is a high-performance, ready-to-use roof repair compound designed for instant waterproofing. This single-pack, solvent-based acrylic compound is reinforced with fibres to bridge small cracks and resist rain immediately after application—making it an essential product for fast, reliable roof maintenance.

Product Features/Specifications:

Presented in a mid-grey finish, Bostik Flexacryl is a fibre-reinforced, solvent-based roof coating ideal for both emergency and planned repairs. With no need for a primer on most surfaces, it provides a seamless, flexible finish that accommodates minor structural movement and adheres to most roofing materials.

Detailed Product Benefits:

Bostik Cementone Flexacryl is engineered for all-weather performance. Unlike standard roof coatings, its fibre-reinforced formulation allows it to bridge small gaps and cracks, delivering a continuous, elastomeric membrane that remains flexible under changing temperatures. Rainproof in just minutes, it can be applied even during damp conditions, minimising downtime and protecting structures from further water ingress. Its high bond strength ensures excellent adhesion to roofing felt, asphalt, concrete, metal, and other common substrates.

Applications and Versatility:

Perfect for both emergency patchwork and long-term maintenance, Flexacryl is suitable for flat and pitched roofs, guttering, flashing, bituminous surfaces, and metal sheeting. Whether sealing around chimneys, skylights, or valleys, this product offers a quick and easy solution without requiring specialist tools or prior priming. Ideal for domestic and commercial roofing projects where speed and durability are critical.
