Palatine Rubber Bitumen Emulsion is a high-performance, thixotropic, cold-applied rubberised bitumen emulsion designed to provide a durable, flexible, and waterproof coating. Upon application, it appears brown but dries to a tough, black finish. This product is specifically formulated to protect concrete and brick foundations, retaining walls, and bridge abutments from water ingress and sulphate attacks present in soils.
Benefits:
- Waterproofing: Provides a reliable waterproof membrane for various structures.
- Protection: Shields concrete structures from sulphate attacks.
- Versatility: Suitable for floors, walls, and various substrates including felt, asphalt, lead, zinc, aluminium, concrete, slate, timber, and corrugated roofs.
- Ease of Application: Can be applied to damp surfaces and dries to a flexible coating.
Typical Uses:
- Waterproofing Structures: Ideal for tanking and waterproofing concrete and brick foundations, retaining walls, bridge abutments, and culverts.
- Surface Treatment: Effective for treating interior and exterior floors, vapour barrier walls, and roofs.
- Damp Proofing: Provides a damp-proof membrane for concrete beams and columns before cladding.
- Plastering: Enhances keying properties on difficult surfaces like gloss painted walls and old tiles.
Please note: This is a water based emulsion and must be completely dry before being subjected to wet conditions
Surface Preparation
Ensure all surfaces are sound, stable, and free from dust, dirt, grease, oil, and loose material.
Can be applied to damp (not waterlogged) surfaces.
Porous or hot dry surfaces should be dampened with clean cold water before application.
Application
Stir well before use.
Apply using a brush.
Do not apply in wet weather or if rain is expected.
Ensure good ventilation in confined areas.
Allow each coat to dry completely before applying the next.
Drying times
Drying times are dependant on Temperature, Humidity and substrate porosity, therefore it is not possible to give a definitive time but normally the DPM would dry overnight.

Special Applications
Floors (Sandwich Construction): Apply 2 coats at 1 m²/L. Blind second coat with sand. Apply 50mm screed.
Interior Walls (Moderate Damp): Apply 2 coats at 2 m²/L. Leave 300mm untreated for moisture escape.
Exterior Walls: Apply 3 coats at 2 m²/L. Blind final coat with sand.
Plastering on Difficult Surfaces: Apply 2 coats at 4.5 m²/L. Blind second coat with sand before plastering.
Cleaning
Clean tools with warm water before the product sets.
If dried, remove with White Spirit or paraffin.
Q: What is Rubber Bitumen Emulsion DPM and what does “DPM” stand for?
A: Rubber Bitumen Emulsion DPM is a cold-applied, rubberised bitumen emulsion designed to form a flexible, waterproof coating. “DPM” stands for Damp Proof Membrane — meaning this product helps prevent moisture migration through structural elements.
Q: Where should I use Rubber Bitumen Emulsion DPM?
A: It is ideal for waterproofing concrete and brick foundations, retaining walls, bridge abutments, tanking systems, and other below-ground structures. It can also be used on floors, walls, and to protect against sulphate attack in soil.

Q: Can I apply it to damp surfaces?
A: Yes — the product can be applied to damp (but not waterlogged) surfaces. However, surfaces must be sound, stable, and free from dust, grease, or loose material. Porous or dry substrates should be pre-dampened with clean water before application.
Palatine Paints
Q: How many coats are required and what is the coverage per coat?
A: For floors (sandwich construction): apply 2 coats at ~1 m² per litre. Blind the second coat with clean sand.
For interior walls with moderate damp: 2 coats at ~2 m² per litre.
For exterior walls: 3 coats at ~2 m² per litre per coat.
Always allow the previous coat to dry fully before applying the next.
Q: How long does it take to dry and when can it be exposed to wet conditions?
A: Drying time depends on temperature, humidity, and substrate porosity. Typically, it will dry overnight. However, because it’s a water-based emulsion, it must be completely dry before being exposed to wet or saturated conditions
