Repairs and Seals: Using Epoxy Cement for Lasting Results

Choosing the Right Epoxy for Repairs

Not all epoxy products are equal—some are tailored for horizontal repairs, while others excel on vertical or sloping surfaces. For surfaces like natural or artificial stone, cement, and metal, a thixotropic, weather-resistant epoxy such as Magelstick Epoxy Mastic is particularly reliable. Its two-component system ensures precise mixing and minimises shrinkage, vital for keeping repairs flush and intact.

How to Apply Epoxy Cement for Optimal Sealing

Start by making sure your surfaces are clean, dry, and dust-free. Carefully mix the epoxy components according to the manufacturer’s recommended 100:50 ratio. Only prepare what you can apply within the pot life to reduce waste. Spread evenly onto your repair or joint, pressing firmly into gaps or cracks. Thanks to its non-sag texture, Magelstick is especially effective for sealing vertical joints and grouting stonework.

• Use above 10°C for best results
• Protect freshly-applied epoxy from heavy rain or frost until fully cured
• For interior decorative sealing, consider a pigmented option such as Vertical Glass epoxy coating

When Careful Repairs and Seals Are Most Critical

Durable sealing with epoxy cement matters most in areas exposed to weather or where materials like stone and cement meet. It’s essential for outdoor restoration, high-traffic hallways, bathroom grouting, and places where movement or moisture could cause structural issues. The right epoxy prevents water ingress, supports stability, and delivers a neat finish.
