A rubberised bitumen emulsion liquid waterproofing membrane for protecting walls, floors, and foundations against water ingress.

Who This Product Is For

This product is designed for construction professionals, builders, and contractors working on waterproofing projects. It also suits experienced DIY individuals undertaking substantial building work where damp proofing is required.

It is appropriate for those working on foundations, retaining walls, bridge abutments, and other structural elements that need protection from water penetration and soil-based sulphate attack.

Key Features

• Waterproofing: Forms a strong, impermeable barrier to prevent water penetration.
• Application: Suitable for use on walls, floors, foundations, and above-ground structures.
• Sulphate Resistance: Protects concrete from soil-based sulphate attack and helps maintain structural integrity.
• Adhesive Properties: Bonds effectively with materials such as wood blocks, insulation boards, and more.
• Dual Finish: Dries from brown to black for a consistent appearance.

Key Benefits

• Provides long-term protection against water damage.
• Straightforward to apply with its formulation.
• Helps extend the lifespan of structures by preventing soil-based deterioration.
• Reduces the need for additional adhesives or bonding agents.

Practical Applications

This liquid waterproofing membrane suits a range of tasks, including:

• Waterproofing floors, walls, and foundations to help stop dampness.
• Protecting bridge abutments and retaining walls from environmental wear.
• Bonding challenging substrates like glazed tiles or expanded polystyrene.
• Acting as a plaster bonding agent for difficult surfaces.
• Providing a curing agent for concrete in construction projects.

How This Fits Into a Typical Job

This damp proof membrane is applied during the construction or renovation sequence after surface preparation but before final finishes. It creates the waterproof barrier that protects structural elements from moisture ingress.

In typical use, it forms part of a system where surfaces are cleaned and prepared, the membrane is applied in coats, allowed to dry, and then subsequent construction layers or finishes are added over it.

How to Use

1. Surface Preparation:
   • Make sure all surfaces are clean, stable, and free from dust, grease, or loose material.
   • If you need a wash-down first, use a masonry and stone cleaner and allow the surface to dry.
   • Dampen hot or porous surfaces with water before you apply the product.
2. Application:
   • Apply evenly using a brush or roller kit.
   • For best results, apply two coats. Let the first coat dry fully.
3. Drying Time:
   • Allow around 4-6 hours for each coat to dry.
4. Finishing:
   • If you paint over the membrane, use a primer recommended by the paint manufacturer.
5. Cleaning Up:
   • Clean brushes and tools with water straight after use to help keep them in good condition.
