By LOTFIX / August 28,2025

Silicone sealant is a highly adaptable adhesive that can be used to repair cracks or fill gaps in doors and glass. Its popularity can be attributed to its ability to create a strong and lasting bond. Whether you need to seal the space around wooden windows, doors, or glass doors and windows, silicone sealant can solve your problem and help you achieve a professional appearance.

The main purpose of silicone sealant is to prevent air and moisture from penetrating through the gap between two surfaces or materials. Its flexibility, elasticity, and ability to withstand extreme temperatures make it the perfect choice for construction and maintenance work. Although some types of silicone sealants may have a curing time of up to 24 hours, the final result is well worth waiting for. Some quick drying alternatives, such as Lotfix D5 quick curing sealant, can cure in just two hours.


To ensure that your silicone adhesive matches the color tone of the material you will be using, it is recommended to choose silicone sealant or sealant of the same color. This is because once applied, the silicone cannot be applied again.

But the design of silicone sealant is to fill gaps, not to support extremely heavy loads. Therefore, they should never be used for load-bearing structures.


Before applying silicone sealant, be sure to carefully read the instructions as additional preparation may be required, especially if you are working on wood or metal surfaces.
