Sealants play a crucial role in home renovation. They are widely used to seal and bond various joints, gaps, and openings. During interior decoration, gaps between building materials and furniture must be properly sealed to prevent dust, water, and other contaminants from penetrating into crevices, which could otherwise lead to bacteria growth and pest infestation.
In addition, sealant application helps refine edges, corners, and connection points, covering exposed substrates and improving the overall visual finish of decorative surfaces. Proper sealing not only enhances durability but also significantly improves aesthetic quality.
There are many types of sealants commonly used in home renovation, including polyurethane sealants, polysulfide sealants, epoxy sealants, and silicone sealants. However, some sealants may contain substances harmful to human health, such as formaldehyde and benzene compounds, which are known carcinogens.
Among all options, silicone sealant stands out as a healthier and more environmentally friendly choice. During both raw material selection and manufacturing, silicone sealants do not introduce toxic substances such as formaldehyde or toluene. As a result, they are widely recognized as a safe sealant solution for residential applications.
Acidic silicone sealant offers strong adhesion and can be used on aluminum alloys, ceramics, and glass. It cures quickly and is generally the most affordable option among different sealant types.
However, due to its acidic nature, it may cause corrosion on certain substrates. During curing, it releases a pungent vinegar-like odor (acetic acid). Although not harmful to the human body, this strong smell makes acidic silicone sealant less suitable for general home interior applications.
Neutral Silicone Sealant
Neutral silicone sealant is suitable for a wide range of substrates, including masonry, aluminum, painted surfaces, and coated materials. It provides excellent sealing performance with minimal odor and no corrosive effects.
Compared with acidic silicone sealant, neutral silicone sealant is slightly more expensive, but its safety, versatility, and mild curing characteristics make it a preferred choice for most residential renovation projects.
For bonding or gap sealing in areas such as interior doors and windows, integrated wall panels, wall cladding, background panels, skirting boards, and decorative moldings, high bonding strength is usually not required. The primary function is gap filling, sealing, and visual enhancement.
Recommended choice: Neutral silicone sealant
Applications such as shower enclosures, sanitary ware, bathtubs, wash basins, sinks, bathroom countertops, kitchen worktops, and basements are constantly exposed to moisture.
Standard waterproof sealants may still develop mold, dark staining, and bacterial growth over time in such environments. Therefore, it is essential to use mold-resistant silicone sealant, which provides long-term waterproofing and hygienic protection.
Recommended choice: Anti-mildew silicone sealant
Exterior joints are continuously exposed to sunlight, rain, temperature changes, and structural movement. These conditions place high demands on sealant durability and flexibility.
Recommended choice: Weather-resistant curtain wall silicone sealant, featuring excellent aging resistance, high movement capability, strong UV resistance, and long service life without cracking or shrinking.
Choosing the right sealant is a common challenge during home renovation. Understanding the application environment and selecting the appropriate silicone sealant can significantly improve sealing performance, durability, and indoor air quality.
