About This Product
Sikadur-31 is a two-component, thixotropic epoxy adhesive and repair mortar — it stays where it's placed on vertical and overhead surfaces rather than sagging, which makes it suited to structural bonding and patch repairs on concrete, stone, steel and masonry. For experienced applicators only, as with any structural epoxy.
System Role
Structural adhesive & repair mortar
Used where a rigid, high-strength bond is required — structural element bonding, edge and corner repair, or filling voids ahead of finishing.
