 How to select and use sealant?

So, are there any sealants suitable for home decoration? How should users choose a suitable sealant for home decoration?

In home decoration, sealants mainly have three application scenarios: one is the bonding and sealing of glass doors, windows and sunrooms; the other is the dry construction bonding of prefabricated wall panels, ceramic tiles, rock slabs and walls, and prefabricated floors. Bonding to the ground; third, edge sealing of door and window covers, skirting boards, kitchen and bathroom countertops, and sanitary ware connections with walls and floors. These three types of application scenarios have different requirements for sealant functions.

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

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

Scenario 3: Gluing is applied in exposed places and is mostly used on white decorative layers, which has an impact on the overall and local effects of interior decoration. Therefore, the sealant must be able to resist the shrinkage and displacement of the base material, always maintain a strong bond, and must be maintained for a long time. The color is stable, non-yellowing and non-mildew. In this scenario, you can choose qualified silicone sealant or modified silicone sealant (MS sealant). It is recommended to choose anti-mildew sealant for kitchens and bathrooms.
