Mapei Bituminous Damp-Proof Membrane, 200L, Suitable for Protecting Floors and Walls Against Rising and Penetrating Damp

Mapei Plastimul DPM 200L is a moisture-activated polyurethane damp-proof membrane. It comes as self-adhesive sheets that prevent rising damp from entering deep walls such as foundations and basements, while remaining water-resistant and breathable.

It’s suitable for use on substrates like concrete, plaster and brick and is designed for damp areas such as basements, foundations and wet rooms (e.g., bathrooms).

Yes. Plastimul DPM 200L provides water resistance to protect against moisture while allowing moisture within walls to escape, helping to manage damp conditions without trapping vapor.

Prepare a clean, dry surface. Unroll the self-adhesive sheets, peel back the backing, and firmly press the sheet onto the substrate using a roller to ensure good adhesion. Overlap sheet edges and seal joints as you go. For complex shapes or penetrations, cut carefully to fit and ensure complete coverage.

It can be applied to concrete, plaster and brick surfaces, making it suitable for foundations, basements and other damp areas.

Yes. Use appropriate PPE such as gloves and eye protection, ensure adequate ventilation during installation, and follow the product’s safety data guidance for handling polyurethane materials.

Plastimul DPM 200L is a moisture-activated polyurethane sheet membrane that is self-adhesive and low-odor. Alternatives on Fepy may differ in size, activation method or substrate compatibility. For example, other Mapei damp-proof membranes available on Fepy include Plastimul DPM 150L (https://fepy.com/product/mapei-plastimul-dpm-150l) and Plastimul DPM 300L (https://fepy.com/product/mapei-plastimul-dpm-300l), which offer similar protection with different coverage options.

Yes. It can be used as a damp-proof barrier in combination with additional waterproofing products or surface finishes. Always ensure compatibility with the materials you plan to install over it and follow any manufacturer guidance.

When installed correctly on appropriate substrates in suitable conditions, Plastimul DPM 200L provides long-lasting damp-proof protection by blocking moisture ingress while remaining breathable. Durability also depends on substrate condition and correct installation practices.

The product is supplied as self-adhesive damp-proof membrane sheets designed for fast installation without additional adhesives. While Plastimul DPM 200L is the 200L option, Fepy carries other sizes such as Plastimul DPM 150L and Plastimul DPM 300L, offering different coverage to suit project needs: 150L (https://fepy.com/product/mapei-plastimul-dpm-150l) and 300L (https://fepy.com/product/mapei-plastimul-dpm-300l).

Yes, it can be used behind tiles or other finishes as part of a damp-proofing regime. Ensure proper surface preparation and adequate adhesion of the membrane before applying decorative finishes or tiling.

Avoid installing on actively running water or on dusty, loose or contaminated surfaces. Ensure sheets are fully adhered with clean overlaps, and seal joints properly to prevent moisture migration. Follow proper cutting and fitting for corners and penetrations to maintain continuous damp-proof coverage.
