Which Adhesive to Choose for Stone Repairs?

Why Epoxy Mastic Is Recommended for Stone Repairs

For stone repairs, particularly where strength and longevity are vital, a two-part epoxy mastic such as Magelstick is an excellent choice. Its thixotropic (non-drip) formulation helps prevent sagging when used on walls or vertical surfaces. This adhesive offers superior mechanical strength, ensuring that repairs on stone, cement, or even metal hold fast and resist the stresses of daily use. Additionally, Magelstick can be applied both indoors and outdoors thanks to its UV and weather resistance, making it suitable for a broad range of restoration scenarios.

Practical Application Tips

When using epoxy mastic for stone, always follow the specified mixing ratio carefully to achieve the best results. Prepare only as much product as you will use within the working time, as two-part epoxies begin curing quickly once mixed. Surfaces should be clean and dry before application to maximise adhesion. The thixotropic texture makes it easy to apply to joints or upright features without mess or waste, while minimal shrinkage ensures a smooth, seamless finish after curing.

When This Matters

• Working on vertical stone surfaces where traditional adhesives might run or drip.
• Outdoors, where UV and weather resistance are needed.
• Renovation or repair of high-stress or structural elements in stone, cement, or metal.
