DescriptionS4Repair EG 21 is a high-performance, two-component, epoxy-based, solvent-free, thixotropic repair, anchoring, and mounting mortar. It is designed for structural repairs, anchoring, and bonding applications on concrete, masonry, ceramics, metals, and stones. With excellent bonding strength, superior chemical resistance, and high durability, it is suitable for both indoor and outdoor use, even in harsh environments where high chemical resistance is required. The mortar provides exceptional protection against water, oils, and various acids and alkalis.✅ Advantages:Ready to use and easy to applySolvent-freeVery high bond strengthDoes not sag in vertical applicationsHigh mechanical strength against impacts and abrasionsHigh chemical resistance against water, mineral oils, fuel, acids, and alkalisWater impermeable�� Application Areas:Repair, bonding, mounting, chamfering, and filler mortarIndoors and outdoorsOn cement-based surfaces, old concrete, and metal surfacesRepair of reinforced concrete structures such as columns, beams, and curtain wallsRepair of large cracksIn ore planting applications in reinforced concrete structuresBonding of concrete elements, ceramics, natural stone, metals such as iron, steel, wood, and glassBonding applications of waterproofing and dilatation tapesEdge, corner hole, and gap filling applicationsOld and new concrete jointsFor assembly works subjected to heavy and medium loadsInstallation of bolts and dowels⚙️ Technical Specifications:PropertyValueChemical StructureEpoxy Resin (Component A), Epoxy Hardener (Component B)Mortar Density~1.8 kg/ltBond Strength (28 days)≥ 3 N/mm² (EN 1542)Compressive Strength (28 days)≥ 60 N/mm² (EN 12190)Bending Strength (28 days)≥ 15 N/mm² (EN 196-1)Curing Time7 days (Full Curing)Consumption1.60–3.20 kg/m² (for 1-2 mm thickness)��️ Application Instructions:Mix the two components (A and B) with a low-speed mixer until a homogeneous mixture is obtained (approximately 3 minutes).Apply the mixture using a trowel or spatula to the surface.The maximum thickness for a single coat is 30 mm.If the primer is applied before, ensure mortar application is completed before the primer dries.⚠️ Warnings:Do not apply in weather conditions below 10°C or above 30°C.Avoid application on surfaces that are wet, frozen, or at risk of freezing within 24 hours after application.Do not add solvents or thinners to the mixture during application.Curing times may vary depending on ambient conditions, so the working time may increase or decrease.�� Cleaning & Storage:Clean tools with solvent immediately after use.Store in a dry, moisture-free environment, and protect from frost. Shelf life is up to 12 months.�� Safety:Wear protective clothing, gloves, and masks during application.Avoid direct contact with eyes and skin.Keep out of reach of children.Consult the Safety Data Sheet (SDS) for further safety information.
