Water Repellent for
Masonry Surfaces
Introduction
PSI 0703 Water Repellent is a water-dilutable solution of potassium
methyl siliconate (Potassium siliconate) developed to impart water
repellency to a wide variety of natural stone and masonry surfaces.
The siliconate reacts with carbon dioxide in the air to form an
insoluble repellent surface and reduce water absorption within
24 hours.
It is suitable for the surface
of natural stone, like sandstone, limestone, and red brick, gray
brick, granite, ceramics etc.; It is not suitable for polished
or glazed surfaces.
Advantages
1. Reduces water absorption into the substrate, thus reducing
spalling due to freeze-thaw and efflorescence, thereby increasing
the life of the substrate.
2. Colorless and non-yellowing protection preserves the natural
appearance of the substrate. Will not form a surface film or gloss.
3. Treated surfaces retain natural vapor permeability.
4. Suitable for interior and exterior surfaces.
5. No solvent odor.
6. Non-flammable.

Applications
PSI 0703 is supplied concentration of 3 percent in water; It may
be used directly, do not dilute it.
Note:
1. Application should be avoided on extremely windy days to avoid
rapid evaporation of the water carrier.
2. It is an alkaline material and should be handled with the same
care as solutions of caustic soda.
3. Stored in airtight, sealed container.
