Removing old sealant, particularly silicone, often requires a bit of effort and the right products. While mechanical scraping is essential, using a dedicated sealant removal gel can significantly ease the process, especially for stubborn residue.
There are two main approaches when incorporating sealant removal gel into your process, as highlighted by practical advice:
Using Sealant Removal Gel: Two Effective Options
Sealant removal gels are designed to break down the sealant material, making it much easier to lift and clean away. You can choose to apply the gel either before or after initial scraping, depending on the condition of the sealant and your preference.
Here are the two primary methods:
-
Option 1: Apply Gel First
- Apply the gel first first and leave the silicone to break down. This method allows the gel to penetrate and weaken the entire layer of sealant before you begin scraping.
- Leaving the gel for the recommended time (check product instructions) makes it much easier to scrape off the softened silicone.
- This can be particularly effective for large areas or very thick, old sealant that is difficult to budge initially.
- After the gel has worked, use a scraper (like a utility knife, razor blade, or a dedicated sealant scraper) to remove the softened material. Clean up any remaining residue.
-
Option 2: Scrape First, Then Use Gel
- Scrape off the old sealant by hand first. Remove as much of the bulk sealant as you can using a scraper. Be careful not to damage the underlying surface.
- Then, use the gel to break down the stubborn bits that won't come off. Apply the gel specifically to the remaining thin layers or difficult-to-reach spots.
- This method targets the hardest-to-remove residue after the majority has been mechanically removed.
- Allow the gel to work, then scrape or wipe away the dissolved or softened remnants.
Both options leverage the chemical action of the gel to reduce the physical effort required, making the sealant removal task more efficient. Always follow the specific instructions on your chosen sealant removal product for best results and safety.
