A weatherproof sealant that lasts as long as the surface it is attached to is the only way to ensure your construction, repair, or renovation projects remain durable and withstand the test of time. Read on to find out which GE weatherproofing sealant is right for your project.

What is a weatherproof sealant?

Do items with the suffix -proof live up to expectations or is it just a marketing gimmick? Your favorite handheld device might be marketed as waterproof, but you might not jump at the idea of swimming with it. Consequently, you might approach the idea of a weatherproof silicone sealant with skepticism.

While there might be a catch with other products, GE delivers what is promised with its line of 100% weatherproof Window and Door Sealants. Weatherproof sealants are silicone-based adhesives designed to create a waterproof and flexible seal around gaps and cracks with the capability to resist temperature and sunlight variations.

The long-lasting protection from moisture, temperature, and sunlight makes weatherproof sealants the ideal choice for exterior fixtures, windows, doors, and gutters that come into contact with the weather.

Why choose a weatherproof sealant?

If a surface is exposed to the elements, the need to ensure it can resist the changes in atmospheric conditions is not hard to imagine. Construction adhesives such as caulk and sealant are designed to seal gaps and ensure drafts, pests, and moisture remain outside of the barrier.

Weatherproof sealants ensure that the seal outlasts the surface it is adhered to, and retains its integrity when exposed to rain, extreme temperatures, and UV radiation.

Weatherproof sealants are designed for outdoor use.

GE’s silicone weatherproof sealants

GE’s line of 100% weatherproof sealants employs advanced technology that makes them the ideal choice for a vast majority of home renovation projects that involve outdoor fixtures.

GE’s window and door sealants

Windows and doors do more than simply adorn your walls. Leaks around doors can facilitate the infiltration of moisture, air leakages, pests, and drafts that can cause mold growth (a direct threat to your health), exorbitant energy costs (a threat to your wallet), or reduce the indoor comfort of your home. Sealing around window and door frames, therefore, is one of the most common ways to use silicone weatherproofing sealant.

GE has just the right sealant for all your window and door needs. GE’s line of window and door sealants include:

Supreme Silicone Window and Door Sealant: The Supreme Silicone Window and Door Sealant is the preferred choice when strength is the most important determining parameter. With seven times more strength than standard silicone sealant, it also carries a lifetime mold-free guarantee.

Advanced Silicone Window and Door Sealant: With five times more strength than standard silicone sealant and a 10-year mold-free guarantee, the Advanced Silicone Window and Door Sealant delivers flexibility to any outdoor project.

All-Purpose Silicone Sealant: The All-Purpose Silicone Sealant by GE is perfect for window and door use along with other applications that might require a flexible, weatherproof sealant.

GE’s specialty weatherproofing sealants

When it comes to the world of renovation, not all surfaces are made equal. When working with special surfaces such as concrete, metal, PVC, or any other non-porous surface, standard weatherproof sealant might struggle to cope. To ensure you retain professional and durable finishes on all of these surfaces, GE offers a line of specialty weatherproof silicone sealants with boosted performance that include:

Gutter Silicone Sealant: You don’t have to worry about an approaching rainstorm when applying the Gutter Silicone Sealant as it is rain-ready in half an hour and provides excellent attachment to both wet and dry surfaces. This weatherproofing sealant is perfect for metal and vinyl gutters in direct contact with rain, sunlight, and extreme temperatures.

Metal Silicone Sealant: If you’ve had to work with high-end metal, you might have noticed that some silicone sealants tend to tarnish the metal finish. Additionally, conventional silicone sealants form a less durable bond with the metal surface. However, GE’s Metal Silicone Sealant is ideal for metal roofs, sheds, vents, sidings, and RVs without discoloring the high-end metal finish.

Concrete Silicone Sealant: GE’s Concrete Silicone Sealant works best for concrete and mortar surfaces. When working on your concrete driveway, you can rest assured that the 100 percent flexible formula provides you with both durability and flexibility. Additionally, the fact that the sealant is rain-ready in 30 minutes makes it easy to use in unpredictable weather such as on a cloudy day.

Where not to use GE’s silicone sealants

All of the weatherproof silicone sealants described in this article have one thing in common, they cannot be painted over. When working on an outdoor project where paintability is the determining factor, you should consider using caulk (which has the downside of not being weatherproof).

Alternatively, if you require silicone sealant properties, you may apply a clear weatherproof silicone sealant over a pre-painted surface, or use a siliconized acrylic sealant.

Weatherproof silicone sealants are the partner you didn’t know you needed for all your home renovation projects. Whether you’re working outdoors or on special difficult surfaces, there is an appropriate GE sealant to help you get the job done.
