Applications
For laminating stone, patching and mending, bonding stone to compatible construction materials and anchor-bolt applications. Select the flowing version where the joint can retain a liquid; knife-grade Express II is a separate formulation.
Selection and Use
- Bond only clean, completely dry, dust-free material without oil, grease or coatings.
- Measure the 2:1 volume ratio and mix small batches that can be placed within the short pot life. Temperature changes affect the setting rate.
- Do not stress the joint before full cure. Some yellowing and chalking can occur under ultraviolet exposure, even though the adhesive is exterior grade.
