JTB Polymer Strengthening Mortar offers high compressive strength, good plastering workability, and reliable resistance to corrosion and aging. Its mechanical properties are comparable to those of concrete, providing good freeze-thaw resistance and long-term durability.
• Good plastering workability
• High strength
• High temperature & corrosion resistance
• Aging resistance & durability
• Eco-friendly
• Plastering for concrete structure reinforcement; stainless steel strand mesh strengthening
• Repair of honeycombs, voids, and exposed rebar on concrete surfaces
• Surface preparation: Remove the milk skin and loose parts on the concrete surface to expose the solid base layer, and remove sand particles, dust, grease and other debris on the surface. Fully moisten the base layer.
• Proportioning and stirring: Calculate the water consumption at approximately 18% to 20% of the powder weight. Use a low-speed stirring device to stir for 3 to 5 minutes, let it stand for 2 to 3 minutes, and then stir again. Each batch of ingredients should be used up within 30 minutes to 1 hour.
• Construction: According to the construction requirements of the project, use a trowel to apply the prepared slurry to the area to be repaired. During application, press it firmly while smoothing it out. It can be put into use 3 to 14 days after completion.
• Reference dosage: 1600kg/m ³
• Maintenance: Cover with plastic sheeting and maintain moist curing for 7 days.
JTB Polymer Strengthening Mortar is ready-to-use upon mixing. Once it sets, it cannot be re-mixed with water for use. During the operation, ensure your safety by wearing personal protective equipment to avoid splashing the material onto your eyes or skin. After the reinforcement is completed, perform appropriate maintenance treatment, such as covering with plastic film or straw mats, to keep the wall moist so that the cement mortar can harden properly.
Packaging Specification: Kraft paper‑plastic film bags, 25 kg ± 1 kg per bag.

Setting a 40-tonne compressor on its foundation looks simple until you measure the gap: typically 25 to 80 millimetres between the underside of the steel baseplate and the top of the concrete. That gap carries the entire operating load, plus vibration, thermal movement and occas...
READ MOREA base plate sits 25 mm above a concrete foundation, and every tonne that presses, vibrates, or torques the equipment above it will pass through that gap. Fill it with ordinary mortar and the mix dries, shrinks, and pulls away from the steel. Leave it as-cast concrete and the co...
READ MOREA concrete patch usually fails where the new material meets the old one. Unmodified cement-sand mortars shrink as they dry, bond weakly to the prepared substrate, and open a hairline gap that admits water and chlorides — the very corrosion cycle you were trying to stop. Polymer-...
