Abstract
An aqueous silane composition for increasing the resistance to penetration by aqueous media of an absorbent substrate is disclosed. The compositions are made from effective amounts of ingredients that initially include: a hydrolyzable silane; a low molecular weight silicone; an amino-functional silicone; an amino-functional silane; and the balance of water. The aqueous silane compositions are characterized by increased shelf-life, increased depth of penetration; and the ability to be made in high concentrations that facilitate lower shipping costs, while at the same time, being dilutable for application to masonry.
