Understanding Silicone Sealants
Silicone is one of the most durable and flexible sealants available, making it ideal for window sealing. It resists moisture, temperature changes, and UV exposure, ensuring long-lasting protection.
Types of Silicone Sealants
- Neutral Cure Silicone – Best for most window applications, odorless, and safe on various materials.
- Acetoxy Silicone – Stronger adhesion but releases vinegar-like fumes during curing.
- High-Temperature Silicone – Suitable for areas exposed to extreme heat.
For most homeowners, neutral cure silicone is the best choice for sealing double glazing windows and frames.
How Long Does Silicone Take to Dry?
One of the most common questions is: “How long does silicone take to dry?” The answer depends on several factors:
✔ Surface Touch-Dry: 30 minutes to 2 hours
✔ Full Cure Time: 24 hours (may vary based on humidity and temperature)
✔ Thicker Applications: Can take up to 48 hours
Tips for Faster Drying
- Apply in thin, even layers
- Ensure proper ventilation
- Avoid sealing in high humidity
Step-by-Step Guide to Sealing Windows

2. Prepare the Surface
- Remove old sealant with a scraper.
