Sika Chapdur Powder Floor Hardener (30 kg HDPE Bag) for Industrial Construction

About Sika Chapdur Powder Floor Hardener (30 kg HDPE Bag) for Industrial Construction

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 Strength and Durability

Sika Chapdur Powder Floor Hardener delivers exceptional compressive strength (>80 N/mm2) and flexural strength (>10 N/mm2), making it ideal for environments where concrete floors face heavy traffic and mechanical stress. The high abrasion resistance ensures floors maintain integrity and finish, reducing maintenance needs and extending service life.


Optimal Application and Coverage

Packaged in convenient 30 kg HDPE bags, Sika Chapdur is applied using the dry shake method at a dosage of 4-6 kg/m2 based on duty requirements. The granular powder spreads uniformly across freshly placed concrete surfaces, forming a hard, dense, and durable layer once integrated by mechanical troweling.


Reliable Protection and Safety

This non-metallic mineral aggregate hardener provides a dust-proof, slip-resistant finish, supporting workplace safety. Its neutral to slightly alkaline pH, non-toxic nature, and odourless composition make it user-friendly for various industrial and commercial settings.
