KYK MegaFloor BYS Z121 | Quartz-Based Concrete Surface Hardener (Grey, Red, Green)
Product Description
KYK MegaFloor BYS Z121 is a cement and mineral-based, quartz-containing, pre-colored concrete surface hardener designed for improving the durability and appearance of fresh concrete surfaces.
Applied as a dry shake powder on fresh concrete, it significantly increases abrasion resistance, surface hardness, dust resistance, and aesthetic quality. Its ready-to-use formulation provides a practical solution for industrial and commercial concrete floors exposed to heavy traffic.
Applications
KYK MegaFloor BYS Z121 is suitable for:
- Warehouses and industrial facilities
- Factories and production areas
- Shopping malls and commercial spaces
- Restaurants and high-traffic public areas
- Interior and exterior horizontal concrete surfaces
- Fresh concrete floor applications
It is especially preferred where durable, wear-resistant, and visually attractive concrete surfaces are required.
Advantages of KYK MegaFloor BYS Z121
Enhanced Surface Strength with Quartz Aggregate
The quartz content increases the hardness, abrasion resistance, and impact strength of concrete surfaces.
Improved Wear Resistance
Provides superior resistance against mechanical wear and heavy pedestrian or vehicle traffic.
Dust-Free Surface Performance
Reduces water absorption and prevents surface dusting, creating cleaner and longer-lasting floors.
Decorative Color Options
Available in Grey, Red, and Green color options to provide both functional and aesthetic solutions.
Smooth Surface Finish
After the surface reaches suitable hardness, high-speed power troweling creates a dense and smooth final finish.
Additional Curing Protection
For improved dust resistance and prevention of shrinkage cracks, KYK MegaFloor Cure Z201 is recommended after application.
Application Instructions
Surface Preparation
- The substrate concrete must be sound, dense, and properly leveled.
- The structural concrete should have a minimum strength class of C25.
- Dust, dirt, and construction residues must be removed before concrete placement.
Dry Shake Application and Finishing
- Fresh concrete should be leveled and prepared until it reaches a consistency where a hand mark of approximately 3–5 mm can be formed.
- Approximately 2/3 of the material is evenly distributed over the surface.
- Allow the material to absorb moisture from the concrete.
- Work the material into the surface using a mechanical power trowel.
- Apply the remaining 1/3 of the material and repeat the finishing process.
- Once the surface reaches walking hardness, complete the final finishing with high-speed troweling.
- Apply KYK MegaFloor Cure Z201 for curing protection.
Application Temperature: +5°C to +35°C
Application Recommendations
- Avoid application during extremely hot, windy, or rainy weather conditions.
- Protect the treated surface from rain for at least 24 hours.
- Ensure proper curing to achieve maximum surface performance.
