nDura FLEX – The Ultimate Decorative Concrete Topping System

Engineered for Performance, Designed for Beauty

At nDura Architectural Concrete Systems, we take innovation seriously. That’s why we developed nDura FLEX, our proprietary, high-performance, pigmented, 100% solids, two-component topping system. Mixed with a wide selection of decorative aggregates and applied at a 3/8-inch nominal thickness, nDura FLEX offers unparalleled durability, aesthetics, and long-term performance.

Unlike traditional concrete toppings, nDura FLEX is engineered for extreme durability, resists cracks and stains, and delivers a seamless, highly decorative finish that lasts decades with minimal maintenance. When paired with our Waterproofing and Crack Isolation Membrane, it becomes the most durable and resilient decorative concrete system available today.

Installation Process – Engineered for Strength & Precision

1. Poured-In-Place Pre-Leveling

To achieve the best adhesion and longevity, all substrates must be properly prepared:

Surface Preparation: The existing concrete subfloor must be clean, sound, and free from dirt, oil, grease, or curing compounds that may prevent bonding.
Mechanical Profiling: Surface contaminants are removed through grinding, shot blasting, or scarifying (solvent stripping and acid etching are not acceptable).
Crack Repair & Joint Treatment: All cracks, joints, and voids are treated to minimize telegraphing through the nDura FLEX topping.
Membrane Installation (If Required): For enhanced waterproofing and crack isolation, a high-performance membrane is applied before topping installation.

2. Poured-In-Place Installation

Primer Application: The surface is primed 24 hours before installation and again immediately before pouring, ensuring maximum adhesion.
Material Placement: The nDura FLEX mixture is placed within pre-formed divider strips and troweled to achieve a smooth, uniform finish.
Compaction & Leveling: The surface is consolidated with a 3/8” spike roller to remove air pockets and ensure a dense, even finish.
Curing: The system is allowed to cure for 24-72 hours before proceeding to the polishing and sealing process.

3. Wet Grind & Polishing Process

Initial Grinding:
- Rough grind using 30/40 grit diamond plates to establish a level surface.
- Follow with 80-grit diamond plates to refine the surface.
Grouting & Patching:
- Surface is cleansed and any remaining voids are filled with a specialty grout mix.
- The grout is cured before continuing to the fine grinding process.
Fine Grinding & Finishing:
- Final grind using 80-120 grit or finer, depending on aggregate exposure and finish preference.
- Polishing process follows manufacturer specifications for a satin, semi-gloss, or high-gloss finish.
- The completed nDura FLEX system will provide uniform color and chip density, matching the approved design sample.
