Johnstone's Trade Stormshield Sol Silicate Masonry is formulated for exterior masonry where a breathable mineral finish is required.
Its sol silicate technology helps the coating bond to suitable mineral surfaces while maintaining vapour permeability, making it useful on appropriate renovation and maintenance work where trapped moisture needs to be avoided.
