FAQ:

Q: Which adhesive sealant is best?

A: The Permatex Clear Silicone Adhesive Sealant is our overall best pick. You can use this glue to fix broken mirrors, snow globes, and other similar products. It will maintain its strength across extreme temperatures.

Q: What is the difference between silicone and acrylic sealant?

A: Acrylic sealants are applied around windows and doors to patch leaks that prevent proper insulation. Meanwhile, silicone sealants are commonly used inside the bathroom where their flexibility is helpful on fixtures. Their curing rate, durability, and their paintability are other notable differences.

Q: What is best way to remove silicone sealant?

A: Scrape the remaining softened silicone away using the sharp blade or razor. Scrub all areas where caulk was removed, staying away from existing caulk, with an abrasive pad and mineral oil to remove any last pieces of silicone or silicone residue.

Q: What adhesive to use on silicone?

A: Very little sticks to silicone other than a silicone adhesive itself, short of the silicone substrate being etched in some way. I would strongly suggest using a silicone based adhesive to adhere two silicone surfaces together to achieve acceptable results. A silicone based caulk, silicone transfer tape, or even VHB or UHB tape are all good options.
