For most caulking applications, homeowners will either use an acrylic latex caulking material or one made from silicone compounds. Acrylic caulking is more popular because of its ease of use and because it cleans up well. It also provides a clean, neat seal. It is worth pointing out though that acrylic sealants don’t work well on larger openings. Since they don’t expand that much following application, they may not be able to completely cover up a big opening that’s present along a door or window.

This trait makes silicone the caulking of choice around showers, bathtubs, sinks, and toilets.
