Technical Information
Product Description

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.

  • Single component fast easy application.
  • Cost-effective.
  • Easily penetrates substrates.
  • Nonstaining.
  • Reduces water and chloride intrusion.
  • Increases freeze-thaw resistance.
  • Minimizes efflorescence.
  • Allows water vapor to escape from the structure and resistant to atmospheric contaminants.
  • AASHTO T277-02 (2006R): Low
  • ASTM C1202-12: Low
Packaging & Coverage

Vetoseal XW771 is supplied in 20 Liters Containers.

Theoretical Coverage: 4 - 12 m2 / liter.

Stated consumption data are for general guidance. Actual consumption depends on the nature of the substrate, method of application, and wastage.

Shelf Life & Storage

The original sealed container of Vetoseal XW771 has a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded place below 35ºC.

Application Information
Instructions for use

Design Criteria

Vetoseal XW771 is designed by brush or low-pressure spray in two to three flood coats for maximum performance. Treating tiles by immersion of silane-siloxane solution may slightly reduce the tile bonding that relies on absorption of adhesive paste for bonding.


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 2 to 4 hours between coats (4 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.

Surface Preparation

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.

Additional Information
Health & Sefety

Vetoseal XW771 should not come into contact with skin and eyes or be swallowed. Avoid inhalation of vapor and spray. Use only in well-ventilated areas. In case of insufficient ventilation, wear suitable respiratory protection.

Wear suitable protective clothing, gloves, and eye/face protection. Barrier creams provide additional skin protection.

Should accidental skin contact occur, remove immediately with a suitable skin cleanser followed by washing with soap and water.

In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice.

If swallowed, seek medical attention immediately - do not induce vomiting.
