Bostik 30812207 Cementone Aquaprufe Damp Proofer & Waterproofer is a premium waterproofing solution designed to protect both interior and exterior surfaces from moisture ingress. This 5‑litre, black formulation offers superior adhesion, flexibility, and durability for a wide range of applications.

Key Features

• Solvent‑free composition – Provides an environmentally friendly option without compromising performance.
• High resistance to water penetration – Creates a robust barrier against rain, groundwater, and dampness.
• Excellent adhesion on wet surfaces – Can be applied directly to damp substrates, reducing preparation time.
• Flexible film formation – Accommodates structural movements without cracking.
• Long‑lasting protection – Maintains integrity for years under harsh weather conditions.

Ideal Applications

The product is suitable for a variety of surfaces and settings:

• Exterior walls – Protects masonry, concrete, and brick from moisture damage.
• Interior walls and ceilings – Prevents damp spots in bathrooms, basements, and kitchens.
• Floors – Ideal for tile, wood, or concrete floors that are exposed to water.
• Roofing membranes – Enhances the waterproof layer of flat roofs and terraces.
• Waterproofing joints and seams – Seals gaps in construction where water could seep through.

Application Process

1. Surface preparation: Clean the area to remove dust, grease, or loose material. Ensure the surface is dry but not excessively wet unless specified for a wet‑surface application.
2. Mixing: Stir the product thoroughly until it achieves a uniform consistency. Avoid overmixing to prevent foaming.
3. Application method: Use a brush, roller, or spray gun depending on surface size and texture. Apply evenly in layers of 2–3 mm thickness.
4. Curing time: Allow the first coat to dry for at least 4 hours before applying a second coat if needed. Full cure typically occurs within 24 hours under normal conditions.
5. Inspection: After curing, inspect the surface for uniform coverage and absence of defects such as bubbles or streaks.

Performance Benefits

The Cementone Aquaprufe Damp Proofer & Waterproofer delivers:

• Superior water‑tight seal – Prevents moisture penetration even in high‑humidity environments.
• Resistance to UV and weathering – Maintains colour and integrity under sun exposure.
• Low VOC content – Reduces indoor air pollution during application.
• Compatibility with other coatings – Can be layered over existing waterproof membranes or paints.

Maintenance & Longevity

Once applied, the product requires minimal upkeep. Periodic inspections every 3–5 years are recommended to ensure continued performance. If minor surface wear occurs, a fresh coat can be applied directly over the existing layer without extensive preparation.

Environmental Considerations

• Solvent‑free formula – Eliminates harmful solvents, making it safer for both applicators and occupants.
• Low VOC emissions – Contributes to healthier indoor air quality during curing.
• Recyclable packaging – The 5‑litre container can be recycled according to local regulations.
