Italy has always influenced global architecture through its deep emphasis on aesthetics, craftsmanship, and long-lasting materials. As outdoor living spaces continue to define Italian design—from terraces in Florence and balconies in Rome to pool decks along the Amalfi Coast - stone carpet flooring has emerged as one of the most desirable surface systems for modern residential and commercial projects.
Stone carpet (also known as resin-bound stone) blends natural stones marble, quartz, river stones—with a high-performance polyurethane binder. The result is a smooth, seamless, breathable, and visually elegant surface that perfectly complements Italy’s outdoor architecture.
However, while the stones define the look, the binder defines the performance.
This is where Drocarp™ 401 and Drocarp™ 402, advanced 2-component polyurethane binders from D.R. Coats, bring engineering precision to Italy’s design-driven flooring market.
Italy’s architectural culture values materials that combine:
Stone carpet flooring aligns with all these principles, making it ideal for:
Pool decks
Northern Italy experiences cold winters and humidity; southern Italy experiences high heat and UV exposure.
Stone carpet systems:
This makes them more stable than tile, concrete, or epoxy-based solutions.
While the natural stones provide the architecture, the binder provides the engineering.
A high-quality binder determines:
Drocarp™ binders are engineered to meet exactly these demands.
Drocarp™ 401 and Drocarp™ 402 are two-component polyurethane binders supplied as:
When mixed together, they create a 100% solids, solvent-free binder that is ideal for outdoor stone carpet systems.
| Parameter | Part A | Part B |
|---|---|---|
| Appearance | Pale yellow liquid | Clear, water-white liquid |
| Viscosity @ 25°C (BF) | 3000–5000 cPs | 2000–4000 cPs |
| Mixing Ratio (A : B) | 100 : 100 phr | - |
| Gel Time @ 25°C (100 gms) | 40–60 minutes | - |
This balance of viscosity and gel time gives installers excellent workability while ensuring strong mechanical properties after curing.

Infrastructure
Drocarp™ binders support each of these applications by providing the necessary strength, flexibility, and UV stability.
Epoxy tends to:
Polyurethane offers:
This aligns with Italy’s architectural need for durability + beauty.
With Drocarp™ 401 & 402, D.R. Coats provides:
Contractors, manufacturers, and architects benefit from:
Stone carpet flooring is becoming a signature trend in Italian outdoor surface design—combining natural beauty, comfort, and long-term durability. As the aesthetics of modern Italian architecture evolve, there is increasing demand for seamless, breathable, UV-resistant flooring systems that can withstand weather, wear, and time.
Drocarp™ 401 and 402 polyurethane binders deliver exactly that:
a perfect balance of architectural elegance and engineered performance.
Whether used for terraces in Milan, pool decks in Sicily, or pedestrian pathways in Florence, Drocarp™ binders provide Italy’s designers and installers with a future-ready solution that enhances both form and function.
1. Why are PU binders preferred for stone carpet flooring in Italy?
PU binders like Drocarp™ 401 & 402 offer superior UV resistance, flexibility, and long-term durability—ideal for Italy’s climate and outdoor spaces.
2. What is the mixing ratio for stone carpet systems?
The recommended formulation is 100:100:1500 (A:B:Stone) per the official Drocarp™ 402 TDS.
3. Can stone carpet be used around pools?
Yes — Drocarp™ binders resist water, chlorine, salt, and detergents, making them suitable for wet areas such as pools and fountains.
4. What aggregate size is recommended?
2–6 mm natural stone, marble, or quartz aggregates, as noted in the TDS.
