The newly renovated living room didn’t stay fresh for long. The walls began peeling, cracking, and losing their finish. This was frustrating, to say the least. However, the source of this issue isn’t just poor workmanship or subpar materials. A lot of the time, it’s the way the base layer was handled during construction that causes these problems.
Start with a Solid Base
So how do you avoid these headaches? First, the wall needs to be solid, completely dry with a moisture content of less than 10%, and any old base layers should be thoroughly cleaned. Some builders use 821 putty when finishing new homes. Unfortunately, this type of putty tends to crumble easily, so it should always be removed and replaced. Second, apply a primer before reapplying the putty. This helps neutralize the pH of the wall, strengthens the base layer, and improves adhesion between the wall and the final coat. Always opt for a reputable brand's primer rather than using random glue.
Lastly, and perhaps most importantly, choosing the right putty is crucial. For a smooth finish before painting, you’ll want to apply two coats of high-quality, water-resistant putty from a well-known manufacturer. These putties tend to be whiter, more durable, and less prone to cracking or flaking. Once the putty job is done, you can confidently apply quality latex paint to your walls.
Whether you’re considering “standard paint,†“eco-friendly paint,†or “green paint,†the first thing to check is whether it meets national standards for hazardous substances. In theory, compliant paints are safe. While volatile organic compounds (VOCs) in paint can be harmful, the key is moderation. As long as the VOC levels fall within acceptable limits, they won’t pose significant health risks. There’s no need to panic unnecessarily.
Choosing the Right Paint
Just like with other products, the paint market has its fair share of fakes and knockoffs. To stay safe, it’s best to invest in well-known brands when buying paint. This ensures both quality and peace of mind for you and your family.
Don’t be fooled by fancy labels or the word “green†on the packaging. Always check the product’s quality inspection report, inspect the paint can for signs of rust or leaks, and verify that all necessary markings are present. For imported paints, look for ones with Chinese labels and descriptions for easier understanding.
Many low-quality paints have excessive levels of harmful substances like VOCs and formaldehyde, often giving off strong odors that can make people feel unwell. If you notice a pungent smell while shopping, proceed with caution. Additionally, avoid scented paints since additives themselves can be harmful chemicals.
Keep your receipt and, if possible, ask the seller to open the can so you can examine the contents. Poor-quality paint might show severe separation, while good-quality paint will cling to a stick when stirred and spread smoothly without dripping excessively. Lighter colors are usually better indicators of quality. (Translated by Zhong Jie)
