US Heritage Group Hosts Historic Masonry Repointing, Stone Repair Training
US Heritage Group will host Historic Masonry Repointing and Stone Repair Training classes at its headquarters in Chicago in January, February and March.
One-Day Lime Putty Mortar Certification Training
Learn the tricks to “Walk-Away Installation” that can give you a competitive advantage by producing superior results while eliminating the need to re-work joints and acid wash surfaces from mortar smears. Overcome the surprises and challenges facing experienced masons as they struggle with their best attempts at repointing with lime putty mortars.
Authentic mortar matches cannot be achieved by mixing masonry pigments to ready-mix, striking the joints wet and washing down the work with muriatic acid. The first step is to establish the match based on the key historic ingredients. Second is to mix and apply the mortar properly.
