Application Overview
Interior decoration sealants are widely used in residential renovation, commercial fit-out, hotels, apartments, and office buildings, involving substrates such as wood, gypsum board, ceramic tiles, glass, metal, and stone.
In interior environments, sealants are not only used for bonding and sealing, but also play a key role in finishing quality, aesthetic appearance, and long-term durability.
Compared to exterior applications, interior decoration requires sealants with excellent material compatibility, low shrinkage, paintability, low odor, and easy application. Improper sealant selection may lead to cracking, discoloration, poor adhesion, or unsatisfactory finishing results.
Common Challenges/Pain Points
Multiple substrates in one area require excellent compatibility
Exposed joints demand clean and smooth finishing
Ordinary sealants tend to shrink or crack after curing
Indoor environments are sensitive to odor and corrosiveness
