What to do if the newly renovated house is eye-catching

The newly renovated house is eye-irritating because of excessive toxic gases. People should not move into such a house immediately. It is better to live in it after sufficient ventilation to avoid the impact of formaldehyde on the human body. You can ask a professional formaldehyde removal company to clean the formaldehyde, or you can use activated carbon to absorb formaldehyde, which can reduce the formaldehyde content to a certain extent.

If a newly renovated house looks unpleasant to the eyes, it means that the content of harmful gases in the decoration materials exceeds the standard, such as formaldehyde, benzene, toluene, ammonia, etc. These gases are extremely harmful to human health. Therefore, do not live in a newly renovated house. It is best to fully ventilate the house for more than 3 months before moving in.

If the newly renovated house is eye-irritating, you can ask a professional formaldehyde removal company to test the formaldehyde content in the house. If formaldehyde or other toxic gases exceed the standard, you need to use a special formaldehyde removal instrument to remove the formaldehyde to reduce the harm of formaldehyde to the human body.

Activated carbon can absorb formaldehyde and harmful gases. You can place a large amount of activated carbon in the corners of your home and in your wardrobe to make it play its adsorption role. Note that activated carbon needs to be replaced every 7 to 15 days to avoid excessive adsorption and secondary pollution.

Toxic substances in newly renovated houses

1. Formaldehyde is a colorless, soluble, irritating gas. Artificial boards such as particleboard, density board, plywood, adhesives and wallpaper are the main sources of formaldehyde in the air, and the release period is as long as 3 to 15 years. It can be absorbed through the respiratory tract. The harm of formaldehyde to the human body is long-term, latent and hidden. Long-term inhalation of formaldehyde can cause serious diseases such as nasopharyngeal cancer and laryngeal cancer.

2. Benzene is a colorless gas with a special aromatic smell. Glue, paint, coating and adhesive are the main sources of benzene in the air. When benzene and benzene derivatives are inhaled by the human body, they can cause central nervous system anesthesia; they can inhibit the body's hematopoietic function, reduce red blood cells, white blood cells and platelets, and increase the incidence of aplastic anemia; they can also cause abnormal menstruation in women and congenital defects in the fetus.

3. Radon is a colorless, odorless, and undetectable inert gas. Construction materials such as cement, brick sand, marble, and tiles are the main sources of radon, and a large amount of radon will also be released in geological fault zones. Radon and its progeny enter the human body with the air, or adhere to the tracheal mucosa and lung surface, or dissolve into body fluids and enter cell tissues, forming internal radiation, inducing lung cancer, leukemia, and respiratory tract lesions.

4. Ammonia is a colorless gas with a strong pungent odor. It mainly comes from admixtures such as concrete antifreeze and flame retardants in fireproof boards. It has a strong irritating effect on the eyes, throat, and upper respiratory tract, and can cause poisoning through the skin and respiratory tract. In mild cases, it can cause congestion, increased secretions, pulmonary edema, bronchitis, and dermatitis. In severe cases, laryngeal edema and laryngeal spasm may occur, and it can also cause breathing difficulties, coma, shock, etc. High ammonia content can even cause reflex respiratory arrest.

5. Volatile organic compounds include formaldehyde, benzene, p-(m-)(o-)xylene, styrene, ethylbenzene, butyl acetate, trichloroethylene, chloroform, undecane, etc. Volatile organic compounds are toxic and irritating, can cause immune disorders, affect the function of the central nervous system, and cause symptoms such as dizziness, headache, drowsiness, weakness, and chest tightness. They may also affect the digestive system, causing loss of appetite, nausea, etc. In severe cases, they can damage the liver and hematopoietic system, and even cause death.

Decoration precautions

1. Do not choose damp wood and store it carefully to prevent deformation

When purchasing wood, you must go to a large wholesaler, not a street shop. Because the wood from large wholesalers is generally dried at the place of origin and then shipped in containers. Wholesalers directly pick up the goods from the containers and then transport them to the home of the owner of the renovation, which reduces the chance of the wood getting damp. If you are still worried, you may as well ask for a humidity test on the wood using a hygrometer when purchasing, so that you can be sure of it. It should be reminded that the wood should be placed in the house for two or three days after it is bought back, and then construction can be carried out after it adapts to the ground atmosphere. Before construction, the ground should be kept dry and a moisture-proof layer should be laid. In this way, the wood will basically not deform.

2. Buy tiles and check the moisture content to prevent cracks

There are many kinds of tiles. When buying in spring, you should pay attention to their water content. Products with smooth and delicate surface, crystal luster, and soft matte feel are products with better water content. At the same time, you should pay special attention to the difference between pottery and porcelain. Porcelain tiles have low water absorption, fine structure, and crisp and pleasant knocking sounds, while pottery tiles have high water absorption, many structural holes, and dull knocking sounds. Porcelain tiles with low water absorption are not easy to crack when the temperature difference between day and night changes in spring. In addition, when choosing materials, you must choose elastic latex paint and adhesives, and then add helpers to prevent the corner lines from drying out and breaking when the spring breeze comes.

3. Choose a good decoration company and sign a formal contract

Formal decoration companies that mainly focus on home decoration mostly provide a one-year warranty for the owners. They each have their own unique skills in spring moisture prevention. Therefore, industry insiders suggest that it is particularly important to hire a formal decoration company for decoration in spring. But if you hire a "guerrilla" to decorate, you will have to endure more fatigue. After choosing a company, you should first check their office location, understand the company's reputation, and keep their phone number. If you find a problem, you should report it to the Municipal Decoration Industry Association and the Municipal Consumer Council in a timely manner. The contract is an important "weapon" for consumers to safeguard their legitimate rights and interests, so you must be more careful when signing a home decoration contract. In the process of signing a decoration contract, consumers should pay special attention to the name of the company, that is, the name of the contractor on the contract should be consistent with the name on the decoration company's business license. For items in the contract that need to be filled in after consensus between the two parties, try not to omit them; after the contract is signed, the official seal of the decoration company must be affixed. In addition, you should also pay attention to whether the relevant regulations on post-decoration repair and maintenance services are stated. Be sure to listen to the decorator's plans for waterproofing and moisture-proofing first, and sign a one-year warranty contract with the decorator to facilitate your negotiations with the decorator about decoration problems exposed by seasonal changes.

4. Leave expansion joints when laying the floor to prevent the floor from warping

When using boards on the construction site, they should be padded with wooden squares. They should not be placed directly on the ground, let alone in places prone to moisture such as kitchens, bathrooms, and balconies. When applying paint, the base moisture-proof primer cannot be saved. After painting, pay attention to ventilation and strive for maximum drying. In addition, you can choose to apply lining cloth when treating the base of the wall to ensure that the wall will not crack. It is best to do waterproof and moisture-proof treatment when laying wooden floors. The normal procedure is: use pearl cotton or asphalt to prime, and then leave expansion joints when installing the floor. In this way, the floor will not warp, nor will it turn black or moldy due to moisture. During construction, be sure to ask the installer to leave enough expansion joints so that the floor will not warp when summer comes. At the same time, pay attention to keeping the indoor air dry. It is hot and humid in spring, and the paint dries slowly after being applied. Moreover, after the paint absorbs moisture in the air, a layer of fog will be produced, so a drying agent is generally used to make the paint dry quickly. Similarly, latex paint is not easy to dry, and it will mold and taste bad if it is not done properly. This requires turning on the air conditioner to dehumidify after construction to completely remove moisture from the air.
