Terrazzo, a cement-based composite material, is gaining popularity for its durability and aesthetic appeal in both commercial and residential buildings. Known for its unique look, this material is made from chips of marble, quartz, granite, stone, or glass set in a cement or polymer render. The resulting surface is then ground and polished to a smooth finish. This blog post explores everything you need to know about terrazzo, from its composition to installation and maintenance.
What is Terrazzo?
Terrazzo is a versatile material that can be made in place or precast before installation. It’s used for interior and exterior surfaces such as floors, stairs, and walls, as well as for baths and kitchen benchtops. The wide range of colors and grain sizes allows for diverse designs. The color of terrazzo comes from the selection of colored stone or crystal chips, as well as coloring agents mixed into the cement.
Terrazzo is often laid in panels separated by dividers made of strips of brass, aluminum, glass, or even wood. These panels can also be used to separate colors and create unique floor patterns. Metal strips often mark transitions between sections, color changes, or material differences. Additional chips can be sprinkled on top of the mix before it sets. Once cured, the surface is ground and polished to achieve a uniform texture. The term “terrazzo” is sometimes used to describe any similar pattern.
Terrazzo in Bali: A Cost-Effective Choice
Terrazzo is particularly popular for floors and stairs, especially in government buildings. It’s also becoming a go-to choice for baths, kitchen tops, and washbasins. In Bali, the labor-intensive process of making terrazzo is more cost-effective compared to other countries. If you are thinking about including terrazzo in your project, here are a few things to consider:
Installation and Care
When it comes to installing terrazzo for baths, ensure that the base structure is robust. Avoid using light concrete blocks with a thin skim of cement, as this isn’t strong enough to withstand the weight of a full bathtub. Instead, use concrete with steel reinforcement. Also, consider the size of your terrazzo bath, as large ones can take a long time to fill with a regular hot water heater. A demand-type heater may be more suitable for larger tubs.
Maintaining terrazzo is crucial to preserving its beauty and longevity. Follow these tips:
- Clean terrazzo regularly, but remember that it has a sealant.
- Avoid using abrasive cleaners such as cream cleaners, scouring powders, or scouring pads. These can remove the sealant, making the surface susceptible to stains.
- Instead, use gentle cleaning methods, such as soap and warm water.
Repairing terrazzo can be challenging, especially if it’s cracked. Crack repairs tend to be superficial, often not looking great and likely to crack again. In many cases, it’s better to replace the entire section. If your terrazzo needs deep cleaning, polishing, or resealing, consider hiring a professional. Be sure to select a tradesman with a proven track record and good references.
In conclusion, terrazzo is a great material to include in your projects here in Bali, offering both durability and aesthetic appeal. By taking note of the installation and maintenance tips outlined above, you can ensure that your terrazzo surfaces remain beautiful and functional for years to come.
