Question 1

What is Henkel WB 200l High-Coverage Poly Prime and what does it do?

Accepted Answer

Henkel WB 200l High-Coverage Poly Prime is a water-based emulsified bitumen primer designed to create a strong bonding foundation for bituminous waterproofing systems. It primes the substrate to improve adhesion with torch-applied membranes and oxidized bitumen, promotes longevity, and supports faster project progress thanks to its quick-drying formulation. It comes in a 200 L container and emphasizes low VOC/environmental friendliness.

Question 2

Which substrates is Poly Prime WB suitable for priming before bituminous membranes?

Accepted Answer

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.

Question 3

How does Poly Prime WB compare to other primers available on Fepy in terms of performance?

Accepted Answer

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.

Question 4

What are the key specifications and attributes of Poly Prime WB?

Accepted Answer

- 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.

Question 5

How should I apply Poly Prime WB to a substrate?

Accepted Answer

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.

Question 6

How long does Poly Prime WB take to dry and when can I apply the next layer?

Accepted Answer

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.

Question 7

Is Poly Prime WB environmentally friendly and safe to use?

Accepted Answer

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.

Question 8

What are the typical use cases or applications for Poly Prime WB?

Accepted Answer

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.

Question 9

How does Poly Prime WB compare with smaller-pack alternatives on Fepy (like 20 L or 5 L sizes)?

Accepted Answer

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:

Question 10

What safety and handling considerations should I know when using Poly Prime WB?

Accepted Answer

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.

Question 11

Is there a clear value proposition for choosing Poly Prime WB, and are there return options if it doesn’t meet needs?

Accepted Answer

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.

Question 12

How can I maximize performance from Poly Prime WB in a project?

Accepted Answer

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.
