S4Repair SM 13 SULPHATE RESISTANT, NON-SHRINKAGE STRUCTURAL REPAIR MORTAR (R4)

DescriptionS4Repair SM 13 is a high-performance, cement-based repair mortar that is polymer and fiber-enhanced for structural repair applications. It is specifically designed for bonding and repairing concrete, stone, and masonry elements. This non-shrinkage, thixotropic mortar provides excellent bonding strength, high compressive strength, and superior resistance to impacts and vibrations. It is also resistant to sulphate, water, and frost, making it ideal for use in harsh environmental conditions.✅ Advantages:Easy to applyThixotropic structure, ideal for vertical and horizontal applicationsDoes not shrinkProvides high bonding shortly after applicationHigh compressive strength and resistance to impacts and vibrationsResistant to sulphate, water, and frostDoes not contain corrosive materials�� Application Areas:Indoors and outdoorsHorizontal and vertical applicationsRepair and leveling of concrete and reinforced concrete structural elementsIn subsoil, above ground, and underwater environments requiring sulphate resistanceFilling gaps between old and new concreteFilling rod holes and core cavitiesChamfer applications before waterproofing⚙️ Technical Specifications:PropertyValueChemical StructureCement-based, polymer and fiber-added powderDensity~2.05 g/cm³ (±0.1)Mixture Ratio3.75–4.25 L water / 25 kg powderPot Life~25-30 minutesApplication Thickness5–40 mm (for local repairs)Bond Strength to Substrate (EN 1542)≥ 2 N/mm²Compressive Strength (EN 12190)Day 1: ≥ 20 N/mm², Day 7: ≥ 45 N/mm², Day 28: ≥ 60 N/mm²Bending Strength (EN 12190)≥ 8 N/mm²Soluble Chlorine Content≤ 0.05%Consumption1.90–2.10 kg/m² (for 1 mm thickness)Reaction to FireA1��️ Application Instructions:Ensure the surface is clean, smooth, and solidMix the product with clean water until a homogeneous mixture is achievedApply with a trowel to the affected areaFor thicker applications, multiple layers can be applied, with each layer allowing sufficient drying time before applying the next⚠️ Warnings:Do not apply in weather conditions below 5°C or above 30°CAvoid application in areas at risk of freezing within 24 hoursDo not apply on wet or frozen surfaces, or surfaces at risk of frost�� Cleaning & Storage:Clean tools with soapy water immediately after useStore in a dry, moisture-free area, unopened, for up to 12 months�� Safety:Wear protective clothing, gloves, and masks during applicationAvoid contact with eyes and skinKeep out of reach of childrenConsult the Safety Data Sheet (SDS) for more details
