INSTALLATION
Surface Preparation & Use
Use gloves, wear eye protection, and avoid skin contact. When grinding cured materials, wear a dust mask. Mix only the amount of material which can be used in 15 minutes. Clean uncured HRM Historic Restoration Mortar from tools with hot, soapy water. Remove cured material mechanically. Recommend testing an area of the structure before applying to large sections.
Mixing instructions
All materials should be at or above 55°F. Priming: For best adhesion, do not apply product to dry surfaces- light misting is appropriate. Mix part b well before using. Combine the two ingredients of powder and liquid until a slurry or knife grade desired consistency is obtained. Determine the powder to liquid proportion that works and handles the best for your particular application. Use a straight edge trowel to spread the material. Lightly mist the repair mortar with clean water immediately after application. Allow to cure before carving, grinding, or shaping.
Temperature dependency: Temperature will affect the working properties of the material. Minimum temperatures are above 50F.
MAINTENANCE: Designed for application in areas inaccessible to maintenance procedures.
Application Thickness: The Historic Restoration Mortar(HRM) is recommended for maximum thickness of 1 inch per application. For a thickness greater than 1 inch, multiple layering applications are recommended.
