Dry shake hardener for concrete floors

About Dry shake hardener for concrete floors

 91 000 74051 Sika Chapdur (IN) is a one-part, premixed, coloured mineral dry-shake hardener used for concrete floors. When broadcast and worked into fresh concrete, it creates an extremely hard-wearing, abrasion-resistant, dust-proof surface. Ideal for areas subject to heavy mechanical wear like warehouses, parking lots, factories, service stations, public floors, and more. 
Key Features & BenefitsReady to use; simple application method. High wear resistance & impact resistance. Dust-proof surface; easy to clean. Non-metallic, rust-free formula. Increased resistance to oils and grease.
Q1. What is the coverage of one 30 kg bag?A: For heavy duty (~5.5-6.0 kg/m), one 30 kg bag will cover approximately 5 to 5.5 m. For lighter duty, higher coverage.Q2. Can I apply this on any concrete/slab?A: The substrate concrete must be good quality, fully compacted, with slump in the range ~75-110 mm. Compressive strength of the concrete should be at least ~20 N/mm. Surface should be clean and free of weak laitance. Q3. How long before the floor can be used?A: Foot traffic after ~72 hours; full service (heavier loads) after ~7 days, when fully cured. Q4. Is this product suitable where oil / grease / chemical spillage happens?A: Yes the product has increased resistance to oils and grease. However, frequent cleaning and maintenance are needed.Q5. What precautions should I take during application?A:Do not apply in strong wind or excessively dry air.Do not add water over the dry shake once applied.Spread in two stages for better blending: first ~60% then ~40%.Use proper finishing tools (trowels, power trowels) to compact and smooth.Cure immediately after finishing, protect from rain or contamination.

Superior Abrasion Resistance for Industrial Flooring

This dry shake hardener offers a significant upgrade for concrete floors, enhancing surface durability and resistance to wear. When applied to fresh concrete and finished with a power trowel, it forms a robust, dense surface capable of withstanding heavy industrial traffic. Its formulation increases abrasion resistance by up to 300% compared to plain concrete, ensuring the longevity and performance of floors in demanding environments.


Versatile Application and Reliable Strength

Designed for industrial settings, the hardener is characterized by high compressive strength (>70 MPa) and excellent coverage (4-6 kg/m2). Its fine particle size (<2 mm) ensures smooth blending, while the low chloride and water content help maintain structural integrity. With available color options and consistent physical properties, it adapts easily to diverse functional and aesthetic requirements.
