Henkel WB 200l High-Coverage Poly Prime

It is intended to prime substrates used in bituminous waterproofing, with the goal of forming a reliable bond between the substrate and subsequent bituminous membranes. Typical substrates include common roofing and waterproofing materials, such as concrete and masonry, where a bonding primer is needed before applying torch-applied membranes or oxidized bitumen.

Poly Prime WB emphasizes high adhesion to improve the durability of the waterproofing system, along with a faster drying time and low VOC profile. It is formulated specifically for compatibility with torch-applied bituminous membranes and oxidized bitumen, offering easy application and reliable weather resistance—attributes that may set it apart from standard primers on the platform.

- High Adhesion: enhances bonding between substrate and bituminous membranes. - Emulsified Bitumen Composition: provides superior sealing and priming properties. - Versatile Application: suitable as a primer coat before torch-applied membranes and oxidized bitumen. - Enhanced Durability: helps extend the lifespan of the waterproofing system. - Easy Application: designed for use with standard tools and equipment. - Quick Drying Time: fast-drying formula to streamline workflows. - Weather Resistance: performs well under moisture and UV exposure. - Environmentally Friendly: low VOC content. - Cost-Effective: value-driven solution for construction projects. - Quality Assurance: manufactured by Henkel, ensuring consistent quality.

Prepare the substrate (clean and dry the surface). Stir the primer as needed and apply using standard tools such as a brush, roller, or spray equipment to achieve a uniform coat. Allow the primer to dry according to site conditions before placing the torch-applied membrane or oxidized bitumen layer. Recoat if the substrate shows bare spots after the initial dry time.

Poly Prime WB is described as quick-drying, with the next waterproofing layer typically applied once the primer is tack-free under ambient conditions. Exact drying times depend on temperature, humidity, and ventilation, so plan for shorter or longer cycles accordingly.

Yes. The product is low in VOCs and designed with an environmentally considerate profile, making it a greener choice for bituminous waterproofing priming. As with any chemical primer, use standard PPE (gloves, eye protection, and ventilation) and follow site safety guidelines.

Ideal as a primer coat before applying torch-applied bituminous waterproofing membranes and oxidized bitumen. It supports roofing, terrace, balcony, and other waterproofing projects where a reliable adhesion layer is required to ensure the performance of the waterproofing system.

The core performance—adhesion, fast dry, and compatibility with torch-applied membranes—remains the same across pack sizes. The 200 L version is suited for large-scale projects, while smaller sizes (e.g., 20 L or 5 L) offer flexibility for smaller jobs or trial applications. Compare the 20 L and 5 L options to tailor procurement to project size and batching needs: - 20 L: https://fepy.com/product/poly-prime-wb-20l - 5 L: https://fepy.com/product/poly-prime-wb-5l

Handle with standard primer precautions: use appropriate PPE (gloves, eye protection, and ventilation). Store in a cool, dry place in the original container, sealed when not in use, away from heat sources and open flames. Follow the local regulations and MSDS guidance for safe use and disposal.

Poly Prime WB offers a high-adhesion, quick-drying primer with low VOCs, contributing to faster project progression and potentially lower maintenance for waterproofing systems, which translates to overall project value. For returns, refer to Fepy’s standard return terms to determine eligibility and process.

Ensure proper surface preparation (clean, dry substrate), apply a uniform coat with suitable tools, and allow adequate drying before membrane installation. Using the primer as recommended for torch-applied membranes and oxidized bitumen helps achieve optimal adhesion and long-term durability, reducing the likelihood of future failures.
