Acrylic Latex
Acrylic latex caulks are the easiest to apply and smoothen out. They're also the only sealants that clean upwards with h2o. Wait for versions labeled "siliconized" or "plus silicone." Adding silicone to acrylic latex improves adhesion and flexibility.
Polyurethane
Poly caulks are generally tougher than other sealants, making them a practiced choice for driveways and other areas that take a beating. But their gooey consistency makes them difficult to work with. Check the label before painting; you may have to wait several days.
Solvent-Based
Many solvent-based caulks are groovy for roofing because they don't degrade in straight sunlight and can be applied to moisture surfaces. Simply they're gooey and hard to utilise neatly.
Hybrid
Most hybrid caulks combine silicone and polyurethane for top-notch adhesion, flexibility and longevity. They're easier to apply neatly than polyurethane but not every bit easy as acrylic latex. Most aren't labeled "hybrid," so we've pointed out the hybrids in the various photos. Toll is a inkling: High-quality hybrids are normally the most expensive caulks on the shelf.
