Vetoseal XX772
High-efficiency silane-siloxane water repellent (solventbased).
Vetoseal XX772 is a solvent-based silane-siloxane water repellent that’s penetrating and hydrophobic. It penetrates cementitious and stone substrates and works by reaction to increase the surface tension of water (to slide away easily from the surface). Vetoseal XX772 allows the substrate to breathe by giving water vapor space to escape. It also drastically reduces water absorption and has a high resistance to the ingress of chloride ions.
Uses
- To transform construction substrates to water repelling surfaces.
- For cementitious substrates (block and brickwork, precast panels, and plasters).
- To seal and 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 and easy application).
- Cost-effective.
- Easily penetrates substrates.
- Non-staining.
- Reduces water and 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 XX772 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 XX772 as a continuous flood coat using either a soft brush or a low-pressure spray at the correct coverage rate (5 m2/ltr.). Two to three flood coats are sufficient for best performance (leave 2 - 4 hours between coats).
Clean equipment and tools using Vetonit Solvent XX400 immediately after use. Use mechanical means (like a wire brush) to remove residue and cured material.
1. Water Pressure Testing: Vetoseal XX772 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 XX772 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 XX772. 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 XX772.
- 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 XX772 is not a waterproofing membrane designed to withstand hydrostatic pressure. As such, it is recommended for applications where hydrostatic pressure is not a concern.
