Why Do Problems Frequently Occur When Using Household Sealants? How Can We Solve Them?

Sealant is a bonding, sealing and finishing material commonly used in home decoration. As a home decoration auxiliary material, sealant accounts for a very small proportion in home decoration projects, but problems such as odor, debonding, breakage, yellowing, mildew, etc. caused by improper use are widespread and difficult to completely solve, and have become a major pain point affecting the comfort of residents at home. Today we will discuss the causes and solutions to these problems.

1. Why are household sealants prone to problems during use?

Sealant is often called "glass glue". In the eyes of the public, "glass glue" has become synonymous with structural glue, weather-resistant glue, and sealant for construction. As the excellent performance of "glass glue" is widely recognized, it naturally enters the field of home decoration. From the development history of sealant products, we can see that the most widely used and largest-volume construction glue is in the fields of curtain wall glass structural bonding, door and window glass sealing bonding, etc. Such products require good weather resistance and strong anti-displacement ability. Therefore, volatile solvents need to be added during the production process. During use, these solvents evaporate into the air as the colloid solidifies, which is the source of the "odor".

Then, let's discuss how sealants enter the home. In the process of home decoration, owners generally entrust third-party decoration companies or construction teams to carry out construction. Whether it is a package of labor and materials, or a package of cleaning and auxiliary materials, for niche auxiliary materials such as sealants, most owners will entrust the construction party to purchase them. In order to save costs and increase profits, the construction party will purchase low-priced and low-quality sealants. In order to reduce costs, manufacturers of low-priced and low-quality products use inferior solvents, reduce glue content, and add inferior solids in excess during production. This causes the sealant to have a strong odor, insufficient bonding properties, poor elasticity, and low chemical stability. After use, users will experience problems such as "odor, debonding, breakage, yellowing, and mildew."

2. How to choose and use sealant?

So, is there any sealant suitable for home decoration, and how should users choose the right sealant for home decoration?

In home decoration, sealants have three main application scenarios: one is the bonding and sealing of glass doors and windows and sun rooms; the second is the dry construction bonding of prefabricated wall panels, tiles, rock slabs and walls, and the bonding of prefabricated floors and floors; the third is the edge sealing of door and window frames, skirtings, kitchen and bathroom countertops, sanitary ware and walls and floors. These three application scenarios have different requirements for sealant functions.

Scenario 1: The sealant needs to face the sun directly, resist the powdering problem caused by ultraviolet radiation, and maintain good bonding and sealing performance between glass and substrate for a long time. Therefore, silicone glue is still the best choice, and qualified silicone structural glue and weather-resistant glue can meet user needs well.

Scenario 2: The amount of glue applied is large, and the glue is sealed between the board, wall and floor, the curing is slow, and the harmful substances volatilize for a long time. Therefore, the environmental protection performance of the sealant is extremely high, and modified silicone glue (MS glue) is more suitable. Qualified MS glue does not add solvents in the production process, does not volatilize harmful substances such as formaldehyde, benzene, isocyanate, etc. during the curing process, and can ensure the indoor air quality after decoration. Among them, when dry-hanging rock slabs and tiles on the wall, it is recommended to choose MS glue products because the bonding performance requirements are higher.

Scenario 3: Gluing is applied in the open and mostly used on the white decorative layer, which affects the overall and local effects of interior decoration. Therefore, the sealant must be able to resist the shrinkage and displacement of the substrate, always maintain a strong bond, and maintain a stable color for a long time without yellowing or mildew. In this scenario, qualified silicone glue and modified silicone glue (MS glue) can be selected. It is recommended to choose mildew-proof sealant for kitchens and bathrooms. The climate in the south is relatively humid, so it is recommended to choose mildew-proof products for the whole house.

3. Conclusion

In short, the selection of different types of sealants should be based on specific circumstances, such as the use location, use environment, environmental protection, durability requirements and other factors. In addition, in addition to choosing the right product type according to the scenario, it is also very important to choose brand products. Whether the owner purchases it by himself or entrusts the foreman to purchase it, it is best to do a good job of research in advance and clarify the brand and model to purchase. Don't affect the decoration effect and home experience because of saving a little money. Therefore, choose our sealant, so that you have no worries.
