1. Introduction: What is Robust Self Flow?

Robust Self Flow is a high-performance cementitious self-leveling compound designed to create smooth, flat, and even surfaces on concrete substrates. It is ideal for both residential and commercial flooring where precise leveling and surface regularity are required before applying tiles, vinyl, epoxy, carpet, or wooden floors.

This advanced formulation from Robust Construction Chemicals combines high-quality cement, graded fillers, and polymer additives that ensure excellent flow characteristics, self-leveling ability, and superior adhesion to substrates. Once mixed with water, it forms a fluid and easy-to-apply compound that naturally spreads out to form a perfectly level surface.

Why Choose Robust Self Flow?

Modern construction demands precision, aesthetics, and performance. Uneven or rough surfaces not only affect the appearance of floor finishes but also lead to premature failures. Robust Self Flow eliminates undulations, improves adhesion for top coatings, and significantly enhances floor performance.

• Mechanical mixer or drill with paddle

• Measuring jug for water

Mixing Procedure:

1. Pour the recommended amount of clean water into the bucket.

2. Gradually add Robust Self Flow powder while mixing.

3. Mix continuously for 3–5 minutes until a lump-free, homogeneous, flowable mixture is obtained.

4. Allow the mix to rest for 2 minutes, then remix briefly before application.

Avoid over-mixing or adding extra water, as it may cause segregation or reduced strength.

7. Application Procedure

1. Pour or Pump the mixed compound onto the prepared surface.

2. Spread evenly using a steel trowel or spreader.

3. Allow the compound to flow and self-level naturally.

4. For large areas, work in sections maintaining wet edges to avoid cold joints.

22. Advanced Technical Insights into Robust Self Flow

A. Composition and Chemistry

Robust Self Flow is a carefully engineered cementitious formulation that combines:

• Portland cement (base binder)

• Redispersible polymer powders (for flexibility and bonding)

• Calcium aluminate (for rapid hardening)

• Graded silica fillers (to improve density and flow)

• Flow and leveling agents (to enhance self-spreading ability)

• Shrinkage compensators (to minimize cracking)

• Defoaming and plasticizing additives

This optimized combination gives the compound:

• Smooth consistency

• Extended working time

• High early strength

• Excellent adhesion to cement-based substrates

B. Polymer Modification Explained

The polymer modification plays a critical role in enhancing the tensile and flexural strength of the self-leveling layer. The polymers increase the compound’s resistance to cracking, improve its elasticity, and enable it to adhere strongly even on slightly flexible or vibrating substrates.

This makes Robust Self Flow suitable for diverse conditions such as:

• High foot traffic areas

• Industrial floors subject to vibration

• Renovation over old concrete substrates

23. Performance and Strength Testing

Each batch of Robust Self Flow undergoes rigorous quality control and testing at Robust Construction Chemicals’ R&D facility.

Long-Term Durability:

Field tests have shown that floors installed with Robust Self Flow maintain their levelness, bond strength, and surface integrity for 10+ years under normal conditions — proving its reliability for long-term performance.

24. Importance of Self-Leveling Compounds in Modern Construction

In modern architecture and interior design, floor perfection is not optional — it’s essential. Uneven floors cause:

• Tile cracking

• Poor finish aesthetics

• Uneven load distribution

• Water ponding in wet areas

• Difficulty installing floor finishes

Robust Self Flow addresses all these issues. It’s a smart solution that not only levels the surface but also prepares the floor to perfection for advanced finishes like:

• Epoxy and polyurethane coatings

• Decorative microtopping

• Vinyl planks or tiles

• Large-format porcelain tiles

25. Step-by-Step Professional Application Guide

This section details how professional applicators ensure optimal results with Robust Self Flow.

Step 1: Surface Inspection

Inspect for cracks, laitance, or moisture content. Moisture content should be below 5% before application.

Step 2: Surface Preparation

Mechanically grind or scarify the surface to remove laitance or contaminants. Vacuum clean the surface thoroughly.

Step 3: Priming

Apply Robust Acrylic Primer diluted 1:1 with water using a roller. This seals the surface and prevents rapid water absorption.

Step 4: Mixing

Use a mechanical paddle mixer. Mix one 25 kg bag with 5–5.5 liters of clean, cool water for 3–5 minutes.

Step 5: Pouring and Spreading

Pour the mixture immediately and spread using a steel spreader or gauge rake. Maintain a uniform thickness.

Step 6: Air Release

Use a spiked roller to release entrapped air and ensure smoothness.

Step 7: Curing

Allow the floor to set undisturbed for at least 6 hours. Protect from direct sun or strong airflow.

Step 8: Floor Finishing

After 24–48 hours, the floor can be ready for:

• Tile fixing using Robust Tile Adhesive

• Epoxy coating

• Vinyl or carpet laying
