Cromar – Cromaprufe DPM Damp Proof Liquid Membrane – 25L (ACP-601)

Cromar Cromaprufe DPM Damp Proof Liquid Waterproofing Membrane – 25 Litre Drum

MPN: ACP/601

Ref: 900428

Barcode: 5036684002837

This advanced waterproofing solution’s 25-litre drum is a versatile, rubberised bitumen emulsion designed for both internal and external applications, forming a robust barrier against water ingress and dampness.

Who This Product Is For

This product is suitable for professional contractors working on construction and waterproofing projects, as well as experienced DIY users undertaking substantial building work. The 25-litre drum size makes it appropriate for medium to large-scale applications.

It is designed for those working on structural waterproofing tasks, including foundation protection, retaining wall treatments, and creating damp-proof barriers in both residential and commercial buildings.

Key Features

• Rubberised Bitumen Formula: Delivers exceptional adhesion and flexibility, ensuring long-lasting protection across diverse substrates.
• Comprehensive Waterproofing: Prevents water penetration into walls, floors, and structures, reducing the risk of moisture-related deterioration.
• Application Flexibility: Suitable for internal and external use on substrates such as brick, concrete, and cement renderings.
• Sulphate Resistance: Protects concrete structures from soil-borne sulphates, extending durability in challenging environments.
• Dual-Purpose Use: Functions as both a waterproof membrane and an adhesive for insulation boards, polystyrene, and more.

Practical Applications

The waterproofing membrane is appropriate for a range of tasks, including:

• Creating a damp-proof sandwich layer for walls and floors to block water ingress.
• Internal and external waterproofing of foundations, retaining walls, and bridge abutments.
• Acting as an adhesive for wood flooring, insulation boards, and plaster bonding on glazed tiles.
• Providing a protective coating for concrete structures exposed to potentially corrosive soils.
• Sealing tanking systems to ensure resistance against water and vapour.

How This Fits Into a Typical Job

This liquid membrane is typically applied during the preparation phase of construction or renovation work, after surface preparation but before finishing materials are installed. It serves as a critical barrier layer in damp-proofing systems.

In a standard application sequence, it follows surface cleaning and preparation, is applied in multiple coats with proper drying intervals, and then becomes the substrate for subsequent building materials like insulation, flooring, or wall finishes.

How to Use

1. Surface Preparation: Ensure surfaces are stable, clean, and free from dust, grease, and loose debris. If working on porous or hot, dry surfaces, dampen them slightly with cold water before application.
2. Application: Use a brush or roller to apply the liquid membrane evenly. Begin with a thin coat and allow it to dry thoroughly before applying a second coat.
3. Layering: For optimal results, apply at least two coats, ensuring complete coverage and forming a strong barrier against moisture.
4. Drying Time: Allow approximately 4–6 hours for drying between coats, depending on environmental conditions.
5. Overpainting: If painting over the membrane, apply a suitable primer beforehand to prevent bleed-through.

• Product FAQs

  Q: What is the primary function of this product?
  A: Its main purpose is to act as a damp-proof barrier that prevents water ingress and protects surfaces like walls and floors from moisture damage.
  Q: Can this be used on damp surfaces?
  A: Yes, it can be applied to damp surfaces, though they should not be waterlogged. Slightly dampening porous surfaces can improve adhesion during application.
  Q: Does this product require a primer?
  A: A primer may not be necessary for initial application; however, to avoid bleed-through when painting over the dried membrane, a primer recommended by the paint manufacturer should be used.
  Q: Is it safe for use indoors?
  A: Absolutely. It is designed for both internal and external applications, making it highly versatile for various projects.
  Q: How many coats are needed for maximum effectiveness?
  A: Two coats are recommended for optimal coverage and long-lasting waterproofing.
  Q: What surfaces is this product compatible with?
  A: It adheres well to materials such as concrete, brick, cement render, wood flooring, insulation boards, and even glazed tiles for plaster bonding.
