Vetoseal XW771 is a water-based silane-siloxane penetrating hydrophobic water repellent. It penetrates the cementitious or stone substrates; it reacts and works by increasing the surface tension of water to slide away from the surface. Vetoseal XW771 allows the substrate to breathe by allowing water vapor to escape the substrate and drastically reducing water absorption and resisting the ingress of chloride ions.
Surfaces to be treated with Vetoseal XW771 must be structurally sound and free from loose materials, grease, oils, or other contaminants. If such contamination is present, it is recommended to remove these by grit blasting and using an industrial chemical degreaser. Repair cracks or holes using a recommended Saveto repair material; allow it to cure before proceeding.
Apply Vetoseal XW771 as a continuous flood coat using either a soft brush or low-pressure spray equipment at the correct coverage rate. Two to three flood coats are recommended for best performance with 4 to 6 hours between coats (4 - 6 m2 / Liter).
Clean equipment and tools using Vetonit Solvent XX400 immediately after use. If residual material exists or hardens, mechanical means such as wire brush would be required to remove residue.
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:
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 for applications where hydrostatic pressure is not a concern.
