How To Remove And Replace The Silicone Sealant

How to remove the old silicone sealant

Cover the area with Cinta-inch painter’s tape about a ¼ inch above and below the joint you want to seal. Place the adhesive tape as straight as possible, and press the edge so that the silicone can not run under it.

To remove and replace the silicone sealant, you must first remove the old silicone sealant so that the new silicone can adhere.

Solution

To remove and replace the silicone sealant, begin by removing as much silicone as possible with a paint scraper, a razor blade or a silicone removal tool. Be careful not to damage the surface.

After scraping as much of the old silicone sealant as possible, apply a product to remove the silicone sealant, following the manufacturer’s instructions. The product will not dissolve the silicone, but it will soften it, and you can continue to remove the silicone sealant.

You can obtain the same result by soaking some paper towels with turpentine and covering the silicone with them. Next, keep the paper towels covered with plastic wrap for an hour or more.

Re-scrape the silicone putty, and you can remove it even more. Next, apply a thin layer of the product to remove the silicone sealant along the joint. Wait for the recommended time and then use a Mr. Clean Magic Eraser pad to remove any remaining silicone.

This will also help you eliminate marks left by the scraper or razor blade. Moisten the Magic Eraser pad with water and scrub the area.

Problem: It seems that there is no old silicone sealant left, but how can you be sure?

Solution: Obliterate the product to remove the silicone sealant and dry the area with a cloth or paper towel. If you used turpentine, remove the paint thinner with a product such as Simple Green. Next, rinse the area with clean water and dry it.

With a paintbrush, apply a small amount of fine powder (it can be flour or composite for joints of drywall or drywall ).

Rub the powder with your finger. This will be inserted in areas where there are traces of soft silicone. Mark these areas (you can do it with a piece of protective tape) and apply the product to remove silicone only in those areas. Scrape with a plastic scraper.

Repeat the process to make sure that the silicone has been removed and allow the area to dry completely before applying the new silicone sealant.

The silicone sealant paste 2

Seal the joint, and run a finger along the joint, so that the bead of sealing paste is uniform.

Problem: If applying silicone is not your specialty, try this method. It takes a little more time, but the result will be worth it.

Solution: Cover the area with Cinta-inch painter’s tape about a ¼ inch above and below the joint you want to seal.

Place the adhesive tape as straight as possible, and press the edge so that the silicone can not run under it. Seal the joint and run a finger along the joint so that the sealing paste bead is even. Remove the protective adhesive tape, and with it, the excess silicone will come out.

The silicone sealant paste 3

Remove the protective adhesive tape; with this one will leave the excess of sealing paste.

Let the new silicone sealant rest for a few minutes, and then “finish” the flange by passing a finger that has been submerged in a solution (50/50) of water and liquid dishwashing detergent along the joint.

The soap will prevent the silicone sealant from adhering to your finger, while you give it the desired shape. Keep dipping your finger in the solution and running it along with the silicone sealant until the entire area is even.

If you remove too much silicone from some area, reapply it and shape it. The new silicone will adhere to the new silicone sealant covered with the soapy solution. Allow the silicone sealant to cure until the next day.

Before trying to remove a moldy silicone sealant, try doing this. Mix bicarbonate with pure bleach to create a paste that you can apply with a spoon or spatula along with the moldy silicone.

Cover the silicone with plastic wrap strips to prevent it from drying out and let it rest until the next day. When removing the plastic wrap and cleaning the silicone, the stain must have disappeared. If not, repeat the process.
