• Grouting Joints. In mortarless joint applications, fill in the joints with a mortar bag. Accidental smears can be removed with a whisk broom after the mortar is crumbly. Never use a wire brush, acid or acid-based product on the stone.

• Finishing Joints. Allow mortar joints to set up approximately 15-45 minutes. Then strike them up with a jointing tool. Weather and the type of surface both influence curing time. Remove extra mortar, then compress and seal the edge around the stone. Brush stones and joints with a whisk broom to finish and clean the project.
