1. Assess the Joint Gap: Measure the expected movement range.
2. Prepare the Surface: Clean the concrete edges thoroughly.
3. Install Backer Rod: Choose the correct size to fit the joint depth.
4. Apply Primer (if needed): Some sealants require surface priming.
5. Insert Sealant: Use a caulking gun to apply an even bead.
6. Tool the Surface: Smooth out for proper adhesion.
7. Cure & Protect: Allow time to cure and protect from water or debris.

Following these steps ensures a strong, long-lasting seal that prevents water ingress and cracking. Always refer to the manufacturer’s datasheet for best results.
