Ramco Hard Worker Floor Screed HW220

Ramco Hard Worker Floor Screed (HW220) is a high-performance, polymer-modified, cementitious screed specifically engineered to provide a perfectly level and high-strength base for all types of flooring. Unlike traditional site-mixed cement-sand screeds that are prone to cracking and unevenness, HW220 is a factory-controlled "dry-mix" solution that ensures a consistent, heavy-duty foundation.

Whether you are preparing a floor for premium vitrified tiles, natural marble, or specialized epoxy coatings, HW220 provides the structural integrity required for modern construction.

Key Features & Benefits

• High Compressive Strength: Formulated to achieve superior load-bearing capacity, making it suitable for both residential interiors and high-traffic commercial environments.
• Low Shrinkage & Crack Resistance: The inclusion of specialized polymers and graded aggregates ensures that the screed does not shrink significantly during the drying process, preventing the formation of structural cracks and "hollow" spots.
• Self-Curing Properties: HW220 is designed to retain moisture more effectively than traditional mixes, reducing the intensity of manual water curing and ensuring the bed achieves its full strength.
• Excellent Workability: The precisely graded sand particles provide a smooth, easy-to-spread consistency, allowing masons to achieve perfect levels and slopes with minimal effort.
• Superior Bond Strength: It creates a powerful bond with the base concrete slab, ensuring the floor remains monolithic and does not de-bond or vibrate under load.
• Uniform Quality: Being a factory-made product, every bag of HW220 delivers the same performance, eliminating the risks associated with poor-quality local sand or improper mixing ratios on-site.

Primary Applications

• Underlayment for Tiles & Stone: The ideal base for laying large-format vitrified tiles, granite, marble, and Kota stone.
• Leveling of RCC Slabs: Used to correct unevenness in raw concrete slabs before the final floor finishing.
• Industrial & Warehouse Flooring: Suitable for areas requiring a high-strength bed to support heavy machinery or vehicular movement.
• Sloped Flooring: Perfect for creating accurate gradients in balconies, terraces, and wet areas like bathrooms to ensure efficient water drainage.

Application Steps

1. Surface Preparation: Clean the base slab to remove all dust, oil, and loose debris. Lightly dampen the surface with water (Saturated Surface Dry condition).
2. Bonding Coat (Optional but Recommended): For maximum adhesion, apply a thin slurry of Ramco Hard Worker HW207 or a cement-water bond coat over the damp slab.
3. Mixing: Mix HW220 with clean water in a designated container or mixer. Stir until a lump-free, semi-dry or flowable consistency (depending on application) is achieved.
4. Laying: Spread the mix over the floor and use a straight-edge (aluminum bar) to level the surface according to the required height markers.
5. Finishing: Compact the screed firmly using a wooden or steel float to achieve a dense, even surface.

Why Choose HW220 Over Traditional Site-Mix?

Traditional "hand-mixed" screeds often use unwashed river sand or "M-Sand" with high silt content, which leads to weak floors that sound hollow over time. Ramco Hard Worker HW220 uses scientifically graded aggregates and chemical enhancers that ensure your expensive flooring has a rock-solid foundation that will last for the life of the building.
