What is the difference between silicone and siliconized caulk?
Siliconized latex/acrylic caulk, on the other hand, is easier to apply and correct than sticky pure silicone, which can be a real pain if you make a mistake during application. But it’s less moisture resistant and more likely to crack with thermal expansion, so a caulk job will be more short lived (30 to 40 years).
