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.

Conclusion

The Bostik 30812207 Cementone Aquaprufe Damp Proofer & Waterproofer stands out as a versatile, high‑performance solution for protecting surfaces against moisture. Its solvent‑free composition, strong adhesion to wet substrates, and durable flexible film make it an excellent choice for both new construction and renovation projects where long‑term waterproofing is essential.
