Patch LRM 143 – High-Performance Fiber-Reinforced, Latex-Modified Cement Repair Mortar

Patch LRM 143 is a premium, cement-based repair mortar specifically engineered for structural concrete applications. Enhanced with powdered latex and reinforced with polypropylene fibers, this advanced mortar ensures exceptional adhesion to concrete and steel, providing superior durability and resistance to environmental stressors. When mixed with the recommended amount of water, Patch LRM 143 forms a smooth, highly cohesive, and long-lasting paste, ideal for repairing and restoring concrete structures.

Designed for both industrial and civil construction projects, Patch LRM 143 is particularly effective in repairing beams, columns, foundations, walls, and other load-bearing concrete elements. Its unique formulation ensures shrinkage compensation, reducing the risk of cracking and ensuring excellent load transfer in repaired areas.

Applications

• High-performance structural repairs using trowel or spray, maximum layer thickness up to 40 mm per pass.
• Repair of load-bearing beams, columns, and slabs subjected to repeated or heavy loading.
• Reinforced and prestressed concrete element repairs without compromising integrity.
• Industrial environments resistant to oils, hydraulic fluids, and chemicals.
• Marine structures including bridges, piers, and dock decks, providing protection against chloride and salt attack.
• Safe for potable water structures.
• Acts as a low-permeability layer, protecting underlying concrete from aggressive agents.

Key Features and Benefits

• Shrinkage-compensated: minimizes cracking and ensures load transfer.
• Primer-free: faster application and lower material costs.
• Sprayable for large areas with minimal waste.
• High durability and very low permeability.
• Fiber-reinforced: polypropylene fibers prevent micro-cracking.
• Safe for drinking water applications.

Technical Specifications

Surface Preparation

• Ensure the substrate is solid, clean, and free of dust, grease, oil, or other contaminants.
• Cut vertical edges to a minimum depth of 14 mm; avoid thin edges.
• Pre-saturate the surface (SSD condition) before applying Patch LRM 143.
• Use mechanical methods like sandblasting, grinding, or scarifying for optimal bonding.

Mixing Instructions

• For one 85 kg bag, use 5–5.5 liters of clean water depending on desired consistency.
• Pour water into a portable electric mixer and gradually add Patch LRM 143 powder while mixing.
• Mix until a homogeneous, bubble-free paste is achieved. Avoid over-mixing.

Application Method

• Spray application using suitable equipment for minimal waste.
• Trowel application: press mortar firmly onto saturated substrate for strong bonding.
• Initial leveling with wooden or plastic trowels; final finishing with steel trowel when partially set.

Curing Instructions

• Cure for 5–7 days using water to maintain moisture.
• Extra care required in hot, dry, or windy conditions for optimal durability.
