1. What Is Rough Face Stone Floor?
Rough face stone floor (split face/rough face) is a type of natural stone flooring whose surface we make rough yet relatively flat through mechanical splitting. Unlike polished glossy stone or smooth machine‑cut (sawn cut) stone, this product displays the natural texture resulting from the split.
We cut the stone with a special saw, then split its middle part so that a rough split face emerges. The final result shows evenly distributed bumps and small indentations that also act as natural grip.
This product measures 10×20 cm. Initially, the stone thickness when still a saw‑cut piece is about 3.5 cm. After manual splitting into two pieces, the final thickness of each piece ranges from 1–1.6 cm. Thus, from one slab you get two pieces with a rough natural front surface and a relatively flat back surface. It is lightweight and easy to install, yet strong enough for pedestrian traffic and wall applications.
2. Production Process: From Quarry to Your Yard
To produce high‑quality rough face stone floor, we carry out a series of stages involving meticulous craftsmen and modern machinery. The complete process is as follows:
- Stone Quarrying: First, we extract stone from the heart of mountains in high‑quality andesite producing areas such as Magelang and its surroundings in Central Java. We select blocks with minimal natural cracks and a uniform base color.
- Block Cutting: Then, gangsaw or water‑lubricated circular saw machines cut large blocks into slabs about 3.5 cm thick. This process minimizes dust and maintains precision.
- Size Cutting: Next, precision cutting machines turn the slabs into 10×20 cm pieces with very small tolerance.
- Manual Splitting (Split): This is the core stage. We split each 3.5 cm thick piece manually using a special chisel and hammer. As a result, this splitting produces two parts, each with one rough natural surface (split face) and one flat surface (sawn). The final thickness of each piece ranges from 1–1.6 cm.
- Cleaning and Sorting: Afterwards, we clean each piece from residual dust, inspect for hairline cracks, and sort them based on color uniformity and thickness.
- Packaging: Finally, we pack the product in bulk for local delivery. However, if needed, we also provide wooden box pallets or carton boxes to maintain integrity.
Note: This product requires pre‑order (no finished stock). Processing time depends on order volume; therefore, please contact us first for an estimate.

4. Advantages of Split Face Floor Compared to Other Materials
- Natural anti‑slip – its rough surface provides high traction, safe when wet without needing additional coating.
- Lightweight – the 1–1.6 cm thickness makes it lighter than thick paving. As a result, transportation and installation become easier, and structural load is reduced.
- Unique aesthetics – each piece is different, creating a natural mosaic that is never monotonous.
- Cost‑effective – from one 3.5 cm slab we produce two pieces. Thus, the cost per square meter is more efficient.
- Application flexibility – suitable for floors, walls, stairs, or decorative accents.
- Eco‑friendly – natural material without combustion processes, low carbon footprint, and recyclable.
- Naturally cool – volcanic stone stays cool even when exposed to sunlight. Therefore, bare feet remain comfortable stepping on it.
5. Why Is a Rough Flat Surface Important for Outdoor Flooring?
The risk of slipping in exterior areas is very high, especially when it rains. Rough face stone floor answers this need through its rough flat texture that creates thousands of micro‑points as natural grip. Water does not puddle, while safety increases, especially for children and the elderly. On the other hand, ceramic or polished granite can be very slippery. For that reason, split face is the safest choice without sacrificing beauty.
6. Design Inspiration for Outdoor Spaces with Natural Stone Split Face
- Running Bond Pattern – alternating arrangement that is neat and easy to install.
- Herringbone Pattern – stones arranged at a 45° angle forming a V, making it suitable for dynamic areas.
- Combination with Grass or Gravel – stones installed as separate stepping stones; gaps filled with grass or white gravel. The natural effect is very strong and water still seeps through.
- Exterior Wall Accent – this lightweight stone can also be applied on walls as a feature wall, combined with climbing plants.
7. Installation Guide for Rough Face Stone Floor
Because the final thickness is only 1–1.6 cm, the installation of rough face stone floor requires special treatment to be sturdy and durable. Therefore, follow these steps:
- Surface Preparation: First, ensure the base floor is flat, clean, and stable. If you are installing over soil, create a thin reinforced concrete work floor with a 1‑2% slope for drainage.
- Stone Soaking: Next, soak the stone in clean water for 5–10 minutes before installation. The purpose is to prevent the stone from absorbing water from the mortar too quickly. Lift and drain.
- Mortar Application: Then, use a special natural stone adhesive mortar (thinbed) with a notched trowel. Apply on the base floor and on the back of the stone (double buttering) for maximum adhesion.
- Stone Placement: After that, carefully affix the stone, press gently, and adjust the position. Use spacers for uniform joint gaps of 3–5 mm. Check flatness with a spirit level and tap gently with a rubber mallet if necessary.
- Cleaning Excess Mortar: Immediately clean any mortar sticking to the stone surface with a wet cloth before it dries.
- Joint Filling: Once the mortar has hardened (24 hours), fill the joints with special joint mortar or a mixture of cement and fine sand. Level and clean again.
- Finishing: Finally, after drying, you can apply a water‑based natural stone sealer if you want to protect it from stains. Make sure the sealer does not make the surface slippery.
Important: Avoid installation in areas frequently traversed by heavy vehicles. In addition, ensure the base is strong enough and there are no cavities under the stone that could cause cracking due to point loads.
8. Maintenance of Outdoor Natural Stone Floor
- Sweep or spray with low‑pressure water for routine cleaning.
- Stubborn stains can be cleaned with a soft brush and mild soap solution.
- Avoid acids, bleach, or abrasive detergents that can alter the stone’s natural color.
- Meanwhile, for moss, use a mixture of water and vinegar (1:1), spray, leave for 15 minutes, then brush.
- You can also apply an optional water‑based sealer for extra protection.
9. Comparison with Other Outdoor Flooring Materials

10. Understanding Color Variations and Characteristics of Natural Stone
The color of split face stone strongly depends on the mineral content during lava solidification. Available natural hues include brownish‑gray, dark gray, to deep black. Since no two pieces are identical, every installation creates a truly exclusive mosaic. Moreover, the dark color contrasts beautifully with green plants. Therefore, the garden looks even more vibrant.
11. Tips for Choosing Quality Rough Face Stone Floor
- Ensure the final thickness is within the 1–1.6 cm range with small tolerance.
- Choose dense stones, without large cavities or natural cracks.
- The split texture should feel uniformly rough; there should be no parts that are still slippery or irregularly chipped.
- In addition, make sure the stock is sufficient to complete your project in one go.
- Buy from a trusted supplier like watucandi.com.
12. How to Calculate Your Rough Face Stone Floor Needs
Size 10×20 cm = 0.02 m² per piece. Therefore, the requirement per square meter is 1 / 0.02 = 50 pieces. Add 5–10% for cutting and damage reserves. For example, for an area of 20 m², prepare about 1,050–1,100 pieces.
13. Price Information and Ordering

14. Testimonials and Real Project Examples
Many residential and commercial projects have already used split face floor. For example, a villa in Puncak combined this stone with black gravel on the garden path. Meanwhile, a café in Semarang used it as a safe and aesthetic terrace floor. Likewise in Yogyakarta, the city’s pedestrian paths applied this material to give a heritage touch that blends with nature.
15. Split Face Floor for Commercial Areas
Because it is lightweight, easy to install, and anti‑slip, split face stone is ideal for outdoor cafés, garden restaurants, boutiques, spas, and resorts. Its rough texture prevents guests from slipping while creating a premium relaxation atmosphere. Furthermore, this material withstands heavy foot traffic without significant wear.
16. Ecological and Sustainability Aspects
The production process of rough face stone floor does not require high‑temperature burning. Consequently, its carbon footprint is low. Although you can install it with cement mortar, if you install it as separate stepping stones, rainwater can still seep into the ground. After its service life ends, the stone can be reused or left to return to nature without polluting the soil.
17. Frequently Asked Questions (FAQ)
Can rough face stone floor be installed indoors?
Of course, this material is very suitable for semi‑outdoor terraces, natural bathrooms, or interior accent walls.
