PROSOCO celebrates 80 years: Innovations in masonry protection

PROSOCO racked up another first in the 1960s with the creation of its Weather Seal line of masonry sealers, penetrating water repellents and masonry stains. While those early Weather Seal products were improvements over what had been used in the past, the emergence of numerous, low-budget competitors created a market full of false claims and lackluster performance. 

In the early 1980s, PROSOCO became the first company in North America to introduce penetrating siloxane water repellents for masonry and steel reinforced concrete.  This marked a dramatic improvement to the levels of performance in protective surface treatments.    

 “Properly formulated, siloxane water repellents penetrate deeply and chemically react with concrete and masonry,” said David Boyer, PROSOCO CEO and President. “They produce long-lasting performance without altering the appearance of treated surfaces. Compared with more volatile silanes that react most effectively on newly installed concrete, siloxanes proved more versatile and yielded predictable, long-term performance on a wider variety of surfaces.”    

Again, copycats arrived soon after PROSOCO’s new range of Weather Seal products hit the market, a reminder to Boyer that there’s no rest for industry pioneers.

“Many producers that initially promoted silane at the expense of siloxane chemistry, soon began to offer siloxanes of their own. That proved again, PROSOCO’s need to keep continually improving to stay ahead of the curve,” he said.
