Henkel Polybit Polyshield HD Damp Proof Membrane

Polyshield HD features a self-adhesive backing for quick, tool-free installation and is made from a polyethylene film laminated with a polymer bitumen adhesive. It is designed to offer both internal and external application with durable waterproofing and UV resistance, which can help it perform better in exposed or sunlit conditions.

It is suitable for use on a variety of substrates, including concrete, brick, blockwork, and plasterboard, making it versatile for different wall and floor surfaces in damp areas.

Yes. The membrane is designed for internal and external use, and its UV resistance helps it hold up when exposed to sunlight. Proper surface preparation and adhesion are important for best results in either environment.

Basic installation steps: (1) Ensure the surface is clean, dry, and free of loose material. (2) Cut the membrane to the required size. (3) Peel back a portion of the backing and apply the membrane to the substrate, pressing firmly to activate the adhesive. (4) Smooth out air pockets with a roller to ensure full adhesion. (5) Seal seams with compatible tape or by overlapping and pressing firmly. (6) For external use, protect exposed edges and joints from abrasion. Always follow surface-specific preparation and seam-adhesion guidance for best performance.

The membrane uses a polyethylene film laminated with a polymer bitumen adhesive, providing a strong, waterproof barrier with a self-adhesive backing for easy handling and installation.

When handling and cutting damp-proof membranes, wear gloves to protect your hands from the adhesive and edges. Work in a well-ventilated area and follow standard safety practices for cutting and handling outdoor/indoor construction materials. Dispose of waste according to local regulations and consult the product’s safety data sheet for any specific guidelines.

Polyshield HD is designed to block water ingress and dampness with a waterproof polymer-bitumen adhesive layer. Its UV resistance also helps prevent degradation when used in sun-exposed areas, contributing to longer-term protection in damp-prone environments.

Compared with standard damp-proof membranes, Polyshield HD offers a self-adhesive application, making installation quicker and cleaner. Its UV resistance and exterior-use capability provide additional versatility for projects that involve external exposure. For direct comparisons, you can consider alternates such as Henkel’s other damp-proof options and other HD membranes available on Fepy, which typically differ in backing, adhesive formulation, and intended use.

Use Polyshield HD in basements, cellars, and bathrooms to prevent dampness and water ingress. It can also be applied to external walls or areas where moisture control is critical, such as under slabs or other damp-prone surfaces, to create a reliable moisture barrier.

Tips include ensuring surfaces are clean and dry before application, cutting sheets precisely to avoid gaps, firmly pressing the membrane to activate adhesion, overlapping seams and sealing them properly, and protecting exposed edges from mechanical damage. For external installations, consider additional protective measures against abrasion and environmental exposure.

Consider the damp-prone conditions, whether you need internal or external protection, and the convenience of a self-adhesive backing. If you require a durable, UV-resistant membrane with quick installation, Polyshield HD offers good value for larger damp-prone projects. Compare with other damp-proof options on Fepy to balance cost, ease of installation, and long-term performance.
