Mapei Bituminous Damp-Proof Coating, 200L, Suitable for Horizontal and Vertical DPC on Foundations and Basement Walls

Mapei Plastimul DPC is a high-performance, flexible and waterproof mortar designed for interior and exterior applications. It works as a render and repair mortar with a built‑in water‑repellent system to resist moisture, provides strong adhesion to concrete, brick and blockwork, and can be used for damp-proofing around walls, columns and other structures.

Yes. Plastimul DPC is formulated for interior and exterior use, making it suitable for renders, repairs and damp‑proofing on walls exposed to different weather conditions.

It offers excellent adhesion to concrete, brick and blockwork, helping restore properties and fix columns and damp‑proof courses when needed.

It incorporates a water‑repellent system within the mortar, helping prevent moisture penetration and minimizing the formation of damp on walls while maintaining good mechanical performance.

It is ideal for highly resistant renderings, plasters and repairs for walls, including surfaces profiled with cement-based finishes or coatings for exteriors and interiors. It’s suitable for restoration projects and new construction where some deformability is expected.

Prepare a clean, sound substrate, dampen as needed, then apply Plastimul DPC with a stiff-bristled brush or trowel until the desired render or repair thickness is achieved. The mortar is designed for straightforward, quick application.

Surface prep (clean, sound substrate), mixing with clean water as per the technical guidelines, applying with a brush or trowel, finishing to the required profile, and allowing proper curing in suitable conditions before the finish coat is applied.

Follow the product’s safety data sheet (SDS). Use appropriate PPE (gloves, eye protection, dust mask as needed), work in well-ventilated areas, and dispose of waste according to local regulations.

Yes. Its combination of adhesion, waterproofing and deformability can reduce maintenance and rework over time, making it cost‑effective for large exterior walls prone to moisture and movement.

Mapei Mapelastic is a flexible cementitious waterproof coating used as a waterproofing layer, while Plastimul DPC is a render/repair mortar with a built‑in water‑repellent system. For larger waterproofing surfaces, Mapelastic can be used as a coating; for renders and repairs where you also need adhesion to substrates, Plastimul DPC is a strong choice.
