Silicone Caulking - Flexseal NS901

Materials You'll Need:

• Flexseal NS901 silicone caulking cartridge
• Caulking gun
• Joint backing rod
• Clean rags or paper towels
• Utility knife or caulk finishing tool
• Isopropyl alcohol (for cleaning surfaces)

Step 1: Preparation

• Ensure the surface to be sealed is clean, dry, and free from dust, dirt, grease, and old caulk. Use isopropyl alcohol to clean the surface if necessary.

Step 2: Load the Cartridge

• Insert the Flexseal NS901 silicone caulking cartridge into the caulking gun. Cut the cartridge nozzle at a 45-degree angle to the desired bead size. A smaller opening will result in a finer bead, while a larger opening will produce a thicker bead.

Step 3: Apply the Caulk

• Hold the caulking gun at a 45-degree angle to the surface, ensuring the nozzle is in contact with the joint. Apply steady and even pressure on the trigger while moving the gun along the joint. Ensure that the silicone flows into the joint evenly. Use a joint backing rod where necessary.

Step 4: Smooth the Caulk

• After applying the silicone caulking, use a caulk finishing tool or the back of a spoon to smooth the surface. This will ensure a clean and professional finish.

Step 5: Cleanup

• Wipe off excess caulk from the surface and your tools using a clean rag or paper towel. Flexseal NS901 is typically skin-forming within 10-20 minutes, so work efficiently.

Step 6: Allow for Curing

• Let the caulk cure for at least 24 hours before exposing it to water, moisture, or extreme temperature variations.

Step 7: Maintenance

• Regularly inspect the caulked area for any signs of wear, cracking, or damage. Reapply Flexseal NS901 silicone caulking as needed to maintain an effective seal.

Remember to follow the manufacturer's recommendations and safety guidelines provided with the product.
