Hey there! As a supplier of sintered stone, I often get asked about the water absorption rate of this amazing material. So, I thought I’d take a moment to break it down for you. Sintered Stone

First off, let’s talk about what sintered stone is. Sintered stone is a high – performance material made from natural raw materials like quartz, feldspar, and other minerals. These materials are subjected to high pressure and extreme heat, usually around 1200 – 1300 degrees Celsius, in a process called sintering. This process fuses the materials together, creating a dense, durable, and non – porous surface.
Now, the water absorption rate is a crucial factor when it comes to evaluating the quality and performance of sintered stone. It refers to the amount of water that a material can absorb when it’s immersed in water for a certain period. In simple terms, a lower water absorption rate means better resistance to water damage, stains, and mold growth.
For sintered stone, the water absorption rate is extremely low. In fact, most high – quality sintered stones have a water absorption rate of less than 0.05%. That’s incredibly low compared to other common building materials. For example, granite, which is also a popular choice for countertops, typically has a water absorption rate of around 0.4 – 0.6%. Ceramic tiles can have a water absorption rate that varies widely, from less than 0.5% for porcelain tiles to over 10% for some types of ceramic tiles.
The low water absorption rate of sintered stone brings a whole bunch of benefits. First of all, it makes the material highly resistant to stains. Since water can’t penetrate the surface easily, spills like coffee, wine, or oil are less likely to seep in and leave a permanent mark. You can just wipe them away with a damp cloth.
Secondly, it’s great for areas with high humidity or where there’s a lot of water exposure, like kitchens and bathrooms. The low water absorption means that the stone won’t swell or warp due to moisture, ensuring its long – term stability and appearance.
Another advantage is its resistance to mold and mildew. Since water can’t stay on the surface or inside the material, there’s no place for mold and mildew to grow. This is especially important in areas where hygiene is a concern, such as hospitals or food preparation areas.
So, how do we measure the water absorption rate of sintered stone? Well, there are standard testing methods. One common method is to weigh a dry sample of the sintered stone, then immerse it in water for a specific period (usually 24 hours). After that, the sample is removed, the surface water is dried off, and it’s weighed again. The difference in weight before and after immersion is used to calculate the water absorption rate as a percentage of the dry weight.
It’s important to note that not all sintered stones are created equal. The quality of the raw materials, the manufacturing process, and the level of quality control can all affect the water absorption rate. As a supplier, we take great care in ensuring that our sintered stone products meet the highest standards. We source the best raw materials and use state – of – the – art manufacturing equipment to produce sintered stone with a consistently low water absorption rate.
In addition to the water absorption rate, there are other factors that you should consider when choosing sintered stone. For example, the hardness of the stone, its scratch resistance, and its color and pattern. Our sintered stone products are not only low in water absorption but also very hard and scratch – resistant. They come in a wide range of colors and patterns, so you can find the perfect one to match your design needs.
Whether you’re a homeowner looking to renovate your kitchen or bathroom, an interior designer working on a commercial project, or a contractor building a new property, sintered stone is a great choice. Its low water absorption rate, combined with its other excellent properties, makes it a durable and long – lasting material that can stand up to the test of time.
