Caulks and Sealants

It looks like there are four types of caulk:

• Acrylic Latex - for smaller cracks in dry areas - flexible, easy cleanup
• Vinyl Latex - good adhesion, waterproof, also flexible and easy to cleanup
• Silicone - excellent adhesion, long life, waterproof, not paintable, requires rubbing alcohol for cleanup
• Butyl Rubber - heavy-duty, for outdoor applications, can fill large gaps with a backer rod (foam support rod)

Here are instructions on how to apply caulk correctly.
