Acrypol

Acrypol is a leading name in the UK for liquid-applied waterproofing systems, with a strong reputation built over three decades. The brand is especially recognised for its fibre-reinforced coatings, such as Acrypol+, which deliver long-lasting protection for flat roofs, pitched roofs, and a wide range of detailing applications. Designed with ease of use and performance in mind, Acrypol products offer reliable waterproofing even in less-than-ideal weather conditions, making them a go-to choice for reactive maintenance, emergency repairs, and planned refurbishment projects. Their formulations are engineered to provide strong adhesion, high elasticity, and seamless coverage — all essential for coping with structural movement and the demands of UK weather.

Acrypol waterproofing systems are highly versatile and compatible with a wide variety of construction materials commonly found on both new builds and existing properties. These include traditional roofing substrates such as asphalt, bituminous felt, concrete, slate, fibre cement, and metal — including galvanised steel, lead, and zinc. Acrypol coatings are also often used on more specialist surfaces such as asbestos cement sheeting, PVC, brickwork, and guttering. This broad compatibility means the range can be confidently used for everything from large flat roofs and pitched surfaces to complex detailing around skylights, flashings, chimneys, and parapets.

Yes. Acrypol products are trusted by professional roofing contractors, building maintenance teams, and property managers across the UK, but they’re also formulated for ease of use, making them accessible to competent DIYers. Many products are single-component and require no primer or mixing, and the thick, brush-on consistency helps reduce mess and ensure even coverage. For domestic projects such as garage roof repairs or small patch jobs, the ability to apply the coating straight from the tin is a huge time-saver. However, for larger or more complex jobs, or where long-term guarantees are needed, it’s generally advisable to consult a roofing specialist.

A key benefit of Acrypol’s waterproofing range is its suitability for year-round use. Many of its coatings are moisture-tolerant and can be applied to damp surfaces, removing the need to wait for a completely dry weather window — a major advantage in the UK climate. Acrypol+ in particular is designed for emergency repair and patchwork scenarios where time is critical. That said, while application during light rain or high humidity is often possible, it’s still recommended to avoid heavy downpours immediately after application to ensure optimal curing and adhesion. The coatings remain flexible once cured, allowing them to expand and contract with temperature changes without cracking or degrading.

Acrypol distinguishes itself through a combination of user-friendly application, exceptional performance in adverse weather, and a product range tailored to both reactive and preventative waterproofing needs. The inclusion of fibre reinforcement in many of its coatings allows for effective bridging of cracks and gaps — often up to 10mm — reducing the need for additional mesh in many cases. Its formulations also prioritise long-term durability, UV resistance, and minimal maintenance, which helps reduce lifecycle costs for property owners. In addition, Acrypol’s ability to perform on a wide variety of surfaces, coupled with availability in different colours and pack sizes, makes it a practical and cost-effective solution for trade professionals managing multiple site conditions.
