ڤيتوسيل اكس دبليو 771
مانع تسرب مقاوم للماء قائم على السيلان-سيلاكسين بأساس مائي.
Vetoseal XW771 is a water-based silane-siloxane water repellent that’s penetrating & hydrophobic. It penetrates cementitious and stone substrates & works by reaction to increase the surface tension of water (to slide away easily from the surface). Vetoseal XW771 allows the substrate to breathe by giving water vapor space to escape. It also drastically reduces water absorption & has a high resistance to the ingress of chloride ions.

Uses
- To transform construction substrates to water repelling surfaces.
- For cementitious substrates (block & brickwork, precast panels, and plasters).
- To seal & treat natural stone, marble, and absorbent tiles.
- As a sealer for cementitious-based Vetotouch range (of EIFS/ ETICS finishes).
Advantages
- Single component (enables a fast & easy application).
- Cost-effective.
- Easily penetrates substrates.
- Non-staining.
- Reduces water & chloride intrusion.
- Increases freeze-thaw resistance.
- Minimizes efflorescence.
- Allows water vapor to escape from the structure
- Resists atmospheric contaminants.
Usage Instructions
Surfaces about to be treated with Vetoseal XW771 must be structurally sound and free from loose materials, grease, oils, or other contaminants. If contamination is present, we recommend removing it by grit blasting and using an industrial chemical degreaser. Repair cracks or holes using a standard Saveto repair system (and allow it to cure before proceeding).
Apply Vetoseal XW771 as a continuous flood coat using either a soft brush or a low-pressure spray at the correct coverage rate (4 - 6 m² /ltr.). Two to three flood coats are sufficient for best performance (leave 4 - 6 hours between coats).
Clean equipment & tools using Vetonit Solvent XX400 immediately after use. Use mechanical means (like a wire brush) to remove residue & cured material.
1. Water Pressure Testing: Vetoseal XW771 cannot undergo high-water pressure testing. Instead, it is recommended to apply it manually or using a garden spray for testing purposes.
2. Factors Affecting Performance: The performance of Vetoseal XW771 may be influenced by the following factors:
- Erosion, Sandstorms, and heavy storms: Exposure to these environmental conditions can have an impact on the performance of the product.
- Friction: Friction can affect the effectiveness of Vetoseal XW771. Care should be taken to minimize friction during application and subsequent usage.
- Vibration: Vibrations can lead to the development of micro cracks in the substrate, which might compromise the performance of Vetoseal XW771.
- Impact Forces: Any accidents or incidents that result in impact forces on the substrate can also pose a risk to the performance of the product.
3. Waterproofing Capability: It’s important to note that Vetoseal XW771 is not a waterproofing membrane designed to withstand hydrostatic pressure. As such, it is recommended only for applications where hydrostatic pressure is not a concern.
