What is a Stone Carpet and Why is 2-4 mm Gravel the Gold Standard?

A stone carpet is a modern surface made of natural gravel bonded with clear resin. This type of flooring is known for its durability, water resistance, and natural beauty. 2-4 mm gravel for resin floors is considered the most suitable: it provides a pleasant texture to the touch, is easy to work with, and ensures an even resin spread.

What You Should Know Before Getting Started

💡 Here are the main mistakes to avoid and professional tips for a perfect installation:

1. Granulometry is Key

• Too large gravel creates an uneven surface.
• Too fine gravel may be “smothered” by the resin.
• 2-4 mm gravel for resin floors provides the best balance between aesthetics and functionality.

👉 Check out:

• 3-6 mm Gravel – ideal for outdoor areas with heavy traffic
• 5-8 mm Gravel – perfect for three-dimensional visual effects

2. Choose the Right Resin

• Epoxy resin is very durable but may yellow if not treated with UV filters.
• Polyurethane resin is more flexible and suitable for outdoor use, but more challenging to apply.

🎯 Tip: For outdoors, choose a UV-resistant polyurethane; for indoors, epoxy resin works perfectly.

3. Proper Subfloor Preparation is Crucial

• The subfloor must be completely dry, clean, and level.
• Applying a primer coat is essential for perfect adhesion.
