In this video, we’ll cover everything you need to know about glass sealants, from understanding the different types and their properties to choosing the right one for your specific application. We’ll also discuss some common mistakes to avoid and offer tips for a successful application.
So, whether you’re looking to seal your shower door, prevent leaks around your windows, or protect your glass table from scratches, this video has got you covered. Let’s get started!
- Composition: A two-part sealant consisting of a liquid polysulfide polymer and a curing agent.
- Properties:
- Excellent adhesion to glass and other building materials.
- High flexibility and elasticity, allowing for movement and vibration absorption.
- Resistant to weathering, UV radiation, and ozone.
- Good chemical resistance to most common cleaning agents and solvents.
- Available in a variety of colors to match the surrounding materials.
- Applications:
- Sealing insulating glass units (IGUs) for windows and doors.
- Structural glazing applications, where the sealant is used to bond glass panels to the building structure.
- Facade glazing, where the sealant is used to seal the joints between glass panels in curtain walls and other exterior applications.
- Composition: A one-part sealant consisting of a silicone polymer.
- Properties:
- Excellent adhesion to glass and other building materials.
- High flexibility and elasticity, allowing for movement and vibration absorption.
- Resistant to weathering, UV radiation, and ozone.
- Good chemical resistance to most common cleaning agents and solvents.
- Available in a variety of colors to match the surrounding materials.
- Applications:
- Sealing insulating glass units (IGUs) for windows and doors.
- Weatherproofing applications, such as sealing around windows and doors.
- General-purpose sealant for a variety of applications.
- Composition: A two-part sealant consisting of a liquid polyurethane prepolymer and a curing agent.
- Properties:
- Excellent adhesion to glass and other building materials.
- High strength and durability.
- Resistant to weathering, UV radiation, and ozone.
- Good chemical resistance to most common cleaning agents and solvents.
- Available in a variety of colors to match the surrounding materials.
- Applications:
- Structural glazing applications, where the sealant is used to bond glass panels to the building structure.
- Facade glazing, where the sealant is used to seal the joints between glass panels in curtain walls and other exterior applications.
- High-performance sealant for demanding applications.
- Type of application: The type of application will determine the required properties of the sealant. For example, structural glazing applications require a sealant with high strength and durability, while weatherproofing applications require a sealant with good resistance to weathering and UV radiation.
- Material compatibility: The sealant must be compatible with the materials it will be used with, such as glass, aluminum, and concrete.
- Movement capability: The sealant must be able to accommodate the movement of the materials it is sealing. For example, insulating glass units expand and contract with changes in temperature, so the sealant must be able to flex and stretch without cracking or failing.
- Durability: The sealant must be able to withstand the expected environmental conditions, such as exposure to sunlight, rain, and wind.
- Cost: The cost of the sealant should be considered, but it should not be the only factor in the decision-making process.
Choosing the right glass sealant is important for ensuring the long-term performance and durability of the sealed unit. By considering the factors discussed above, you can select the best sealant for your specific application.
There are two main types of glass sealants: silicone and polysulfide. Silicone sealants are more common and are generally less expensive than polysulfide sealants. However, polysulfide sealants are more durable and have a longer lifespan.
The type of glass sealant you choose will also depend on the application. For example, if you are sealing a window, you will need a different type of sealant than if you are sealing a shower door.
If you are unsure about which type of glass sealant to choose, it is always best to consult with a professional. A professional will be able to assess your specific needs and recommend the best type of sealant for your application.
Before applying the sealant, it is important to prepare the surface by cleaning it thoroughly. This will help to ensure that the sealant adheres properly.
Once the surface is prepared, you can apply the sealant. Be sure to follow the manufacturer’s instructions carefully.

After applying the sealant, it is important to allow it to cure properly. This will typically take twenty-four to forty-eight hours.
Once the sealant is cured, it is important to maintain it by cleaning it regularly. This will help to prevent the sealant from cracking or peeling.
Choosing the right glass sealant is important for ensuring that your windows and doors are properly sealed. By following the tips in this video, you can choose the right sealant for your application and ensure that it is applied and maintained properly.
