DAP DynaFlex Ultra Window and Door Sealant

DynaFlex Ultra (dynaflex) sealants are used in all types of doors and windows. They have been developed to provide maximum protection against water intrusion while maintaining the flexibility required for ease of installation.

The main advantages of using a dap sealant over other products include:

• Durable – Daps are designed with durability in mind, which means they will not crack or break down under high temperatures or extreme pressure.

• Waterproof – Daps are waterproof, meaning they won’t allow moisture to enter through them.

• Flexible – Because of their design, daps do not require glue or adhesive to adhere to the surface. Instead, they are applied with a squeegee or applicator tool.

• Easy to Install – Unlike some other sealants, daps are easy to install. Simply apply it with a squeegee or applicator tool and let the product dry completely before applying your next coat.

How does DAP DynaFlex Ultra Sealant work?

DynaFlex Ultra is made up of two different ingredients: silicone oil and polyisobutylene (PIB). The PIB gives the sealant its durable characteristics and provides protection against extreme temperatures, while the silicone oil provides weather-resistance and flexibility.

Because dap sealants are flexible, they are able to easily fill in the small gaps and spaces where other sealants cannot, making them more effective at keeping out moisture. Dap also boasts a low odor, which is ideal for those who are sensitive to strong chemical smells.
