In the current home improvement project, stone is widely used in the local design of the interior, such as: floating window countertops, pass the door stone, wave line, stone floor, decorative wall, ladder step, bathroom countertops, cabinet countertops and so on. However, what kind of stone should be used in various parts of the room, how to choose the stone, how to calculate the amount of the purchase, what precautions when installing ... ... Are you clear about these issues? May wish to hear what the experts say.

Part of stone interior disabled

According to Yang Guangqiang, Chief Engineer of Kuda Decoration, China’s stone is divided into three categories according to the level of radioactivity: A, B, and C. According to regulations, only Class A can be used for home interior decoration, while Classes B and C are used for outdoor decoration. There are two types of natural stone: marble and granite. The radioactivity of marble is generally lower than that of granite. Most of it can be used for interior decoration. Granite should not be used in large quantities in the room, especially in the bedroom, the elderly, and children's rooms. use. Man-made stone varies depending on the ingredients it adds.

Many consumers will think that only natural stone is a good stone, artificial stone certainly is not naturally good. This view is wrong, natural stone is not all safe and reliable, such as high-level radioactive C natural stone can not be used for indoor decoration, and most man-made stone can be used in the indoor professional detection, and artificial stone by production The level of craft is also divided into different grades. In general, regular stone manufacturers and sellers can issue professional inspection reports. Consumers must first choose quality and reliable products.

Different parts are different

Artificial stone is based on unsaturated polyester resin as binding agent, together with natural marble or inorganic powder such as calcite, silica sand, and glass powder, as well as suitable flame retardant and coloring agent, etc. Casting, vibration compression, extrusion and other methods of molding, curing made. It is based on the problems that are easily encountered in the actual use of natural stone. It has made great progress in terms of moisture proofing, acid proofing, high temperature resistance, and patchwork. Of course, man-made stone also has its drawbacks, and the texture is relatively unnatural, so it is mostly used in cabinets, etc., where practicality is more demanding, and places where kitchens, toilets and other environments are relatively harsh. Window sills, floors, etc. emphasize decorative areas and are used less frequently.

When choosing a stone for interior decoration, pay attention to the different stone materials in different locations. When choosing, choose the material according to factors such as hardness, color, and abrasion resistance. Cabinet countertops, pass door stone, wave line, ladder step mainly use rock hardness is relatively strong stone, darker color, good care, color difference, but also rich sense of hierarchy, will not produce a feeling of contempt; floating window table, Decorative wall, floor stone, bathroom countertops can choose rock hardness is relatively weak, the color is diverse, beautiful texture of the stone, such as the bay window, the ground choose more light colors, can give a warm, quiet feeling, but also from the visual On the "expansion" area. It is best not to choose a dark stone and spread it over the ground, which will make people feel “dark and dark”. If the decorative wall can use beige or white stone, it seems simple atmosphere. In addition, considering the strength of the decoration and the load-bearing weight of the house, thin slab stone should be selected.

Select materials first test

The quality of stone depends on the quality of raw materials and processing technology. Under normal circumstances, a good stone should have such characteristics: the surface is smooth, no roughness when touched by hand; the front is bright, the light reflection effect is the same when the light is observed, there is no flickering phenomenon; the trimming is smooth and the side is observed and cut The edge presents a straight line with no serrated pits; the color is uniform and there is no color difference on the surface of each stone; the texture is clear and the texture of the same type of stone is the same without significant differences. The high-quality stone surface does not contain too much variegated color, uniform cloth color, no obvious light and shade transitions, and the quality of the stone will have many irreparable “defects” after processing. Therefore, the pattern tone of the surface is to evaluate the quality of the stone. Advantages and disadvantages of important indicators. If the processing technology and process are not enough, the finished products will have warping, dents, stains, stains, missing corners, cracks, color lines, pits, and so on. This type of stone is a “defective product”. .

In general, imported artificial stone has better performance. For example, imported artificial marble allows grinding scratches on the surface with sandpaper. Consumers can handle it on their own, and many domestically produced artificial stones are more polished. In the purchase, it is best to take a sample plate upside down soy sauce or oil, and wear tests.

Measurement requires loss

The price of stone sold in the market varies greatly from tens of yuan per square meter to over a thousand yuan per square meter. Most products are based on area, and some products are sold at the price of each block or meter.

No matter which part of the room you choose, it is calculated by area. If it is a regular rectangle, it is calculated by length multiplied by width. The irregular shape is calculated by multiplying the length of the longest part in the longitudinal direction by the length of the longest part in the lateral direction. The excess part is a normal loss. In addition, the stone that needs to be edging must also increase the loss of 1-2 cm, double-edged. Generally increase the loss of 3 cm or more.

The stone products purchased by the manufacturers are not only the raw material costs of the stone materials, but also the installation fees and other expenses; if you want to customize the stone products, you have to pay the raw material costs and processing fees (edge ​​grinding, angle cutting, hole digging) , Hanging), transportation fees, upstairs fees, installation fees, etc. It should be noted that some merchants will use the excuse of cutting a small part of the stone from a large plate to collect cutting costs, and consumers can refuse to pay.

Spread the parquet before laying

Buy a stone, basically are the business door installation. However, the installation is not as easy as paving the floor tiles, and some details need to be taken care of. First of all, we must do the mosaic (color) treatment of the stone, even if the same batch of stone, there will be some color, texture is not exactly the same phenomenon, so the mosaic section is important before the pavement, to make the color of the stone, After the pattern is assembled, it will show a gradient effect, and then number it and label it on the back. When labeling, do not select tools for liquid color pigments so as not to infiltrate the material into the stone and dye it.

When paving, first apply a layer of clear cement slurry to the ground, and then use cement mortar as the bottom layer. After diluting and leveling, pour the supernatant into the cement slurry and paste the stone. The thickness of the cement mortar base layer should not be less than 2 cm. Do not walk or press heavy objects, etc. within 8 to 12 hours after laying the stone to avoid empty shell or unevenness. At the same time, it must be noted that some imported stone backs have a plastic network attached to them, and the sheet network must be torn off before installation.

The installation sequence of stone is also stress. Passing the door stone can be installed together with the floor tiles, and can also be installed before the installation of the Anmen line; the floating window table surface can be installed before the last putty before the leveling of the wall surface, which can make up for gaps and will not stain the wall surface; ladder step The platform can be installed after installing the floor tiles. There will be no gaps between the bricks and the step platforms; the decorative walls, washbasins and cabinet countertops may be determined according to the progress of the project.

In addition, the owner also needs to prepare some accessories. Such as the installation of light-colored stone, you need to bring white cement and river sand; dark stone can use ordinary cement; if you directly shop on the wood base, the owner also needs to prepare glass glue.

Do not carelessly wax

The stone is not conquered. Care should be taken when using it. No matter how good the stone is, its resistance to acidity and alkalinity is weak, and it is easily corroded by acid and alkali. Consumers should try to avoid touching this type of material; the surface is polished to avoid hard objects scratching; in addition, the stone has a certain degree of The breathability, it is best not to cover the surface of other materials for a long time, so as not to affect their normal "breathing" and cause changes in water content. It is also necessary to ensure that the surrounding environment is dry. If the stone is in a humid environment for a long time, it will undergo changes such as hydrolysis and whitening.

Care should be taken when using the waterproof agent that can be used with quality assurance. However, it is not free to wax. There are many types of wax on the market, including water-based waxes, stearic acid waxes, oily waxes, acrylic waxes, etc. These waxes basically contain acid-base substances that block the pores of the stone and are easily stained with dust. The formation of wax scales causes yellowing on the surface of the stone; moreover, most of the wax contains ammonia, which can adversely affect the human body and the environment after it is volatilized.
