Interior Tuckpointing

Crews from American Masonry are carefully tuckpointing every interior mortar joint throughout the church. The existing mortar is removed and replaced with new mortar to secure the 4-inch-thick Mankato limestone and help preserve the structural integrity of the building.

Once the stone is stabilized, a specialized cleaning material is applied to the surface. After it cures, the material is carefully peeled away, lifting embedded soot and particulate deposits that have accumulated over the past century and revealing the natural beauty of the limestone beneath.
