Mapei Mapegrout Patch 218 – Fibre-Reinforced, Shrinkage-Controlled Concrete Repair Mortar for Vertical & Overhead Repairs

Concrete defects such as honeycombs, chipped edges, spalled concrete, exposed reinforcement bars, tie-rod holes, surface voids, and damaged precast panels are common problems found in residential, commercial, and industrial construction projects. If these defects are not repaired correctly, they may allow water penetration, accelerate reinforcement corrosion, reduce structural durability, and affect the overall appearance of the concrete.

.

Mapegrout Patch 218 is a professional-grade, fibre-reinforced, shrinkage-controlled cementitious repair mortar specially developed for repairing damaged concrete surfaces. It is manufactured using high-quality cement, selected graded aggregates, special additives, and synthetic fibres to provide excellent bonding, high strength, crack resistance, and easy application on horizontal, vertical, and overhead surfaces.

.

Unlike ordinary cement mortar, Mapegrout Patch 218 is formulated to remain stable after application without sagging, making it an excellent solution for repairing beams, columns, ceilings, walls, slabs, precast panels, drains, water tanks, and many other reinforced concrete structures.

.

Whether you are a contractor, builder, engineer, facility maintenance team, or homeowner, Mapegrout Patch 218 offers a reliable, durable, and professional concrete repair solution that saves time while delivering long-lasting performance.

Why Choose Mapei Mapegrout Patch 218?

Many contractors make the mistake of repairing damaged concrete using ordinary cement mortar. While this may temporarily cover the defect, conventional mortar often shrinks during curing, resulting in cracks, poor adhesion, and repair failure after a short period.

.

Mapegrout Patch 218 is specially engineered to overcome these common repair problems.

.

Its fibre-reinforced and shrinkage-controlled formulation provides stronger bonding with existing concrete while minimizing shrinkage cracks during curing. Once hardened, it develops high compressive and flexural strength with excellent adhesion, creating a durable repair that can withstand everyday service conditions.

.

The mortar is also thixotropic, meaning it stays firmly in place after application. It will not easily slump or fall off vertical walls or overhead ceilings, allowing contractors to repair difficult areas without complicated formwork. Contact Us Buildmate Home Living Sdn bhd

No additional cement, sand or admixtures are required.

Recommended Mixing Ratio

• 25 kg powder
• 3.5 – 4.0 litres of clean water

Mixing Procedure

1. Pour clean water into a clean mixing container.
2. Slowly add the powder while continuously mixing.
3. Mix using a low-speed mechanical mixer for approximately 3–5 minutes until smooth and lump-free.
4. Allow the mixture to stand briefly.

Surface Preparation

Proper surface preparation is essential for achieving maximum bond strength.

Before application:

• Remove all loose concrete.
• Remove dust and dirt.
• Remove grease and oil contamination.
• Remove paint and curing compounds.
• Remove deteriorated concrete.
• Expose sound concrete.
• Roughen smooth concrete surfaces.

Before placing the repair mortar, thoroughly wet the concrete substrate until it reaches a Saturated Surface Dry (SSD) condition. The surface should be damp but free of standing water.

Application Guide

For Concrete Surface Repairs

Apply the mortar firmly using a steel trowel.

Compact the mortar properly to eliminate air pockets.

The maximum recommended thickness is 30 mm per layer.

For deeper repairs, apply additional layers before the previous layer has completely hardened.

For Anchor Bolts & Fixings

Fill the prepared cavity with freshly mixed mortar.

Compact thoroughly to eliminate voids.

Insert the anchor bolt, hinge, pipe support or fixing while the mortar remains workable.

Finish the surface neatly using a steel trowel.

Consumption
