Application Techniques for Best Results

To achieve the best results with 789p, follow these techniques:

1. Load the cartridge into the caulking gun.
2. Cut the nozzle at a 45-degree angle to the desired bead size.
3. Apply an even bead of sealant along the joint or gap, moving steadily without stopping.
4. Use a scraper or your finger to smooth the surface if necessary.

Post-Application Care and Maintenance Tips

After applying 789p, adhere to these maintenance tips:

• Allow the sealant to cure fully before exposing it to moisture or stress.
• Check regularly for any cracks or breakdowns, especially in exterior applications.
• Clean any excess sealant promptly with a suitable solvent to maintain aesthetics.
