Will protect concrete from carbonation by protecting the calcium hydroxide in the cement paste from reacting with the carbon dioxide in the atmosphere, thus reducing the amount of calcium carbonate formed and extending the life and durability of the concrete substrate.
Is hydrophobic and therefore will repel moisture. Water will either evaporate or run off without penetrating the masonry. Is non-toxic, non-flammable and UV resistant.
