【New, Unused】Konishi K-Mortar
Product Details
Case of 2 sets.
New and unused item. Purchased November 2025.
The box may have some scratches, but the contents are new.
K-Mortar is a lightweight, high-strength special epoxy resin mortar formulated with epoxy resin and special lightweight aggregate.
Its lightweight nature allows for thick application on vertical and overhead surfaces, which is not possible with conventional resin mortars.
Furthermore, even when applied thinly, it does not cause dry-out like cement mortar and is highly effective for filling and repairing defects in concrete structures.
■ Applications
Filling and Repair:
Filler for repairing defects and exposed rebar in concrete structures.
Leveling:
Resin mortar for leveling uneven surfaces and steps.
■ Features
Lightweight Mortar:
Weighs 0.8 or less, so it won't sag on vertical or overhead surfaces (for applications up to 20mm thick).
Workability:
Good moldability, allowing for application from thin to thick layers as needed.
Adhesion:
Strongly adheres to concrete substrates.
Durability:
Excellent freeze-thaw resistance and long-term durability.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
