Linseed Oil Preserves Concrete, Naturally
Linseed oil effectively preserves concrete surfaces, naturally. A coating prevents destructive water and salts from penetrating concrete. It stabilizes the smooth concrete surfaces in parking structures, bridges and concrete buildings, and prevents the breakdown of reinforcing steel. A testing program completed at the University of Hong Kong in 1996, proved conclusively that linseed oil-based preservatives extend and enhance the life of concrete.
