After successfully detaching the old silicone, preparing the surface is paramount. Cleaning the area is essential to ensure the new silicone adheres correctly and forms a watertight seal. Utilize isopropyl alcohol or specialized adhesive removers to erase any lingering residue that could compromise adhesion.

In addition to cleaning, it’s advisable to thoroughly inspect the underlying surfaces for any signs of damage. Check for cracks or corrosion, particularly common in outdoor installations exposed to the elements. Any underlying damage should be repaired before applying new silicone. This ensures that the surface onto which the silicone is applied is sound and secure.

Once the area is cleaned and checked, wait for it to dry completely. Silicone works best on dry surfaces, allowing it to bond effectively. Taking the extra time during the cleaning and preparation phase is indispensable, as this often determines the longevity and quality of the new seal.

5, APPLYING NEW SILICONE SEALANT

When ready, you can confidently proceed to apply the new silicone sealant. Using the caulking gun simplifies this process, allowing for controlled and steady applications along the edges of the tubes. Start at one end of the joint and slowly squeeze the trigger while moving along the length of the seam. This technique creates a consistent bead and reduces the chances of gaps or inconsistencies.

As you apply the silicone, check for air bubbles or irregularities. These can weaken the seal and lead to moisture infiltration. If you notice any imperfections, don’t hesitate to smooth the silicone immediately. A moistened finger or a specialized smoothing tool works well for this purpose. Gently run it along the edge, ensuring the silicone fills all the gaps effectively.

Remember to be generous with the silicone; a thicker layer typically equates to better sealing capabilities. After application, do not disturb the seal for at least 24 hours to ensure it cures completely and effectively. Allowing the silicone to set undisturbed fortifies its adhesion and longevity, ultimately leading to better protection for the solar tubes.

6, FINISHING TOUCHES

Once the new silicone cured fully, take some time to inspect the areas you worked on. Look for any spots that may require additional silicone or smoothing to ensure a consistent, professional finish.
