DAP AMP vs. GE Supreme Silicone
DAP AMP is an all-purpose sealant with an advanced hybrid polymer formula. It is ideal for caulking and sealing surfaces.
It is also an all-weather window, door, and siding sealant that has proven effective on wet surfaces.
Another product is GE Supreme, a 100% waterproof silicone caulk for windows and doors. It can provide a reliable seal in weather-prone areas.
GE Supreme is one of the most convenient and effective sealants, with 40% more flexibility and 7X stronger adhesion than any regular silicone sealant.
Set & Cure Time
DAP AMP’s setting time is only 30 minutes. It reaches its maximum strength within 24 hours. Once set, it becomes paintable and can be exposed to water.
It is an all-weather sealant with a 30-minute rain and water-ready formula.
The GE Supreme silicone sealant takes 30 minutes to set, which means both sealants have similar setting times.
However, unlike DAP AMP, this product is non-paintable.
Color
The DAP AMP sealant is white, but the GE Supreme silicone sealant is available in two colors: white and clear.
Performance
The DAP AMP claims to have maximum performance. It is an all-weather sealant for doors, windows, siding, and more.
It has proven to work on wet surfaces and provide long-lasting flexibility. Moreover, it includes low odor, UV resistance, and a lifetime guarantee.
Furthermore, the DAP AMP sealant becomes paintable in 30 minutes. So, it provides faster results, which is a plus.
On the other hand, the GE Supreme is a reliable product that offers a 100% silicone formula, is waterproof, and is weatherproof, protecting against water damage.
It also offers 40% more flexibility and 7X stronger adhesion than regular sealants.
It withstands extreme expansion and contraction due to temperature fluctuations.
It is ideal for interior applications because of its 30-minute rain-ready formula, 50% joint-movement capability without cracking or shrinking, lifetime mold-free protection, and low odor.

The GE Supreme silicone sealant can withstand temperatures from 40 to 100 degrees Fahrenheit, which shows that the DAP AMP can tolerate more.
Resistance & Benefits
The DAP AMP sealant uses a hybrid technology. It is UV-resistant and can be applied to wet and damp areas.
Also, it provides 100% waterproof and weatherproof outcomes on surfaces with superior adhesion.
GE Supreme is a 100% waterproof and weatherproof silicone sealant.
Its 100% silicone formula delivers protection from water damage and offers a reliable seal in weather-prone areas.
Once it’s cured, it is crack—and shrink-proof. That means it withstands extreme expansion and contraction during temperature fluctuations.
It is also resistant to stain-causing mold and mildew growth.
Caution
DAP AMP sealant is a good product, but some precautions must be taken when using it.
This sealant is harmful to the skin and eyes and can cause irritation.
If the product contacts the skin or eye, wash it off immediately with water and consult a doctor.
Do not use mineral spirits or any other solvent to clean the skin.
Use mineral spirits to clean up excess, uncured adhesive from the surface. If it’s cured, scrape it away. Reseal the product for reuse.
GE Supreme is also harmful to the skin and eyes, irritating them. So, taking precautions is a must.
Editor’s Note
DAP AMP has hybrid technology that offers maximum performance in damp areas. It also has UV resistance.
The GE Supreme claims to have a freeze-proof and sun-proof formula.
GE Supreme is a silicone sealant with a lifetime mold-free formula, is shrink—and crack-proof, and is waterproof.
Both are suitable for indoor and outdoor use. One clear difference is that the DAP AMP is paintable, but the GE Supreme is non-paintable.
Overall, GE Supreme is suitable for stronger adhesion.
If you want a waterproof sealant for wet areas and an additional UV resistance formula, then I think the DAP AMP sealant is the better choice.
