At present, about 80% of kitchen/cabinet countertops on the market also use quartz. But when you buy quartz, how do you judge the quality of quartz countertops?

One look

Observe the texture and appearance

From the perspective of raw materials, the main materials of quartz contain more than 90% quartz ore sand and about 10% resin and granular trace elements. There are two main types of quartz ore sand: coarse sand and refined sand. Coarse sand contains more impurities due to screening reasons, and the ore sand is relatively coarse, so it is not as good-looking and durable as the countertop made of refined sand. Since the price of coarse sand and refined sand raw materials is twice that of refined sand, many quartz countertops on the market are made of coarse sand, but not much refined sand.

From the perspective of particles, good quartz has richer particles, including glass particles, quartz sand particles, and metal particles, and good board particles have fewer impurities. Such boards are refreshing, clean and beautiful.

The surface of high-quality quartz countertops should be smooth and flat, without obvious bubbles, cracks or flaws. The color and pattern of quartz should be evenly distributed without obvious color difference or spots.

Second knock

Check the touch and anti-penetration test

According to the hardness of the plate, there are two ways to make quartz: one is die-casting; the other is casting. Casting quartz is directly cast, resulting in pores in the middle of the plate, which makes it easy for the plate to penetrate. Too much resin is easy to crack. Die-cast quartz is to be die-cast by a press, making the plate tighter and denser and not penetrating. Generally, knocking on the countertop on site, the sound is crisper, and the quality of the countertop is more reliable.

By directly touching it, because the hardness and density of quartz are higher, you can clearly feel the warmth and skin-friendly of the countertop by touching it (taking the glossy surface as an example). At the same time, drop water on the surface of the quartz stone to observe whether it will be absorbed. High-quality quartz stone has low porosity, and water drops should stay on the surface for a long time without being absorbed by the diffuser.

Three smell identification

Identify the quality by smell

When cutting this material, due to the high temperature, it may release a smell similar to burning plastic, but after a short period of volatilization, the smell will dissipate.

The environmentally friendly resin used in Aibo quartz countertops will not affect future use. Inferior quartz stone is filled with calcium powder and mixed with more adhesives during the manufacturing process. Even after a long period of volatilization, you can still smell a pungent odor when you smell it closely. This type of quartz stone must not be purchased.

Four quality assurance

Certification and testing

High-quality quartz products usually have relevant quality certifications and test reports, such as the US Green Guard Gold Certification, SGS testing, NSF certification, Korean KS certification, etc. Professional organizations give you an extra layer of protection.

Installation and after-sales

Go to the shopping guide or official online customer service to understand the processing process of quartz stone. High-quality quartz stone should use advanced processing technology to ensure accurate size and smooth edges. Choose a professional installation team for installation to ensure the splicing and installation quality of the quartz countertop.

When purchasing quartz countertops, you should consider its appearance, texture, hardness, impermeability, odor, and whether it has authoritative certification. Observe whether the surface is smooth and flawless, and whether the particles are uniform; knock and listen to the sound to judge the density; check whether water droplets are absorbed quickly; smell whether the odor is pungent and lasting when it is cut; finally, check the product’s quality certification and professional installation service to ensure that the selected quartz countertop is both beautiful and durable.
