A: Priming is generally not required for most substrates. However, for suspect surfaces, adhesion testing is recommended to ensure optimal bonding.

Q: What is the recommended joint design for Everflex JS?

A: Good building practice allows for ±25% movement, though Everflex JS can handle ±50%. The minimum sealant depth is 6mm, and the maximum is 10mm, regardless of joint width. Maintain a 2:1 depth-to-width ratio.

Q: How do I prevent three-sided adhesion with Everflex JS?

A: Use a backer rod or bond breaker tape to control joint depth and prevent the sealant from adhering to the back of the joint, allowing for proper movement.

Q: Is Everflex JS paintable?

A: Yes, Everflex JS is paintable, allowing for seamless integration with the surrounding surfaces and finishes.
