About Sika Chapdur Non Metallic Floor Hardener - Standard Size Industrial Application,Durable Floor Protection

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 Heavy-Duty Flooring

Sika Chapdur Non Metallic Floor Hardener is specifically engineered to increase the abrasion resistance and compressive strength of concrete surfaces in industrial environments. Its non-metallic formulation makes it safe from corrosion, while the application process ensures a dense, hard-wearing surface ideal for warehouses, factories, and high-traffic areas.


Easy Application for Consistent Results

This floor hardener is applied by sprinkling and trowelling directly onto fresh concrete surfaces. With a recommended dosage of 4-6 kg/m2, the process is efficient and ensures uniform protection. The powder's granular consistency allows for easy handling and uniform spread, ensuring reliable performance over large surface areas.


Safe, Durable, and Long-Lasting

Free from hazardous components and odourless, Sika Chapdur ensures safe installation and minimal environmental impact. Its high compressive strength, lasting up to 80 MPa after 28 days, translates into floors that withstand years of heavy use without significant surface degradation. The product comes with a 6-month shelf life when stored in cool, dry, and ventilated conditions.
