Epoxy-Based Mastics: A Useful Guide

Where and When to Use Epoxy-Based Mastics

These specialist adhesives are highly suited for work on natural and artificial stone, metals, and cement. Whether you’re tackling marble restoration, granite repairs, or concrete fixing, epoxy mastics provide durable adhesion and structural integrity. Thanks to their formulation, they’re also suitable for outdoor tasks—resisting sunlight and weather exposure.

• Stonework: Secure bonding of tiles, decorative slabs, and countertops.
• Metal repairs: Fill gaps and cracks in gate posts or garden fixtures.
• Cement surfaces: Reliable solution for patching steps, sills, or masonry.

Get the Best Results: Application Tips

For optimal performance, ensure surfaces are clean, dry, and free from dust or grease. Most products, such as the Magelstick Epoxy Mastic, require thorough mixing of the two components in the correct ratio—check the manufacturer’s guidance, and work in small batches if precision is crucial. The thixotropic nature of quality mastics prevents drips on vertical applications, aiding control and finish. Apply at temperatures above 10°C for best results and allow recommended curing time before stressing the bond.

When Epoxy Mastic Matters Most

Epoxy-based mastics stand out when high strength, weather resistance, and gap-filling on intricate or vertical surfaces are required. They’re especially valuable in restoration, structural repair, and scenarios where a lasting solution is essential.
