Caulk & Sealant: What You Need to Know

Caulks and sealants, often referred to as joint fillers or gap sealers, are designed to prevent air, water, and moisture from entering joints or seams in buildings and structures. Available in various colors like white, gray, clear, and black—and packaging sizes from 1 oz. tubes to full 10 oz. and 28 oz. cartridges—this category supports a wide range of interior and exterior sealing needs.

Type:

  • Caulk: Flexible sealing compound used to fill gaps in windows, doors, baseboards, and trims. Commonly applied in both paintable and waterproof formulas for indoor and outdoor projects.
  • Caulk Guns: Manual or trigger-operated tools designed to apply caulk or adhesive cartridges with precision. Essential for professional-grade control and consistent bead application.
  • Gutter Sealant: Specialized for bonding and sealing joints in metal and vinyl gutter systems. Withstands extreme weather and prevents water leaks at seams and corners.
  • Sealants: Durable and elastic compounds used for sealing expansion joints, plumbing penetrations, and structural gaps. Offers weatherproof, waterproof, and crack-resistant performance in high-movement areas.

Material:

  • Acrylic: Paintable water-based formula ideal for low-movement joints like trim, baseboards, and interior gaps. Easy cleanup and quick drying make it suitable for indoor use.
  • Acrylic Latex: Enhanced acrylic formula that increases flexibility and adhesion. Offers better durability while still allowing for smooth paint coverage.
  • Advanced Modified Polymer: A high-performance hybrid designed for commercial-grade adhesion and flexibility. Bonds to wet surfaces and offers superior UV and moisture resistance.
  • High Heat Resistant: Formulated to withstand elevated temperatures, often used around fireplaces, stoves, and heating systems. Maintains integrity under extreme heat conditions.
  • Installation Foam: Expanding polyurethane foam that fills large voids and irregular cavities. Commonly used for sealing around windows, doors, and penetrations.
  • Latex: Standard interior-use material that offers easy tooling and paintability. Best for sealing drywall, baseboards, and decorative trim.
  • Polyurethane: Premium-grade material used for roofing, masonry, and concrete joints. Highly flexible and adheres strongly to a wide range of substrates.
  • Sealant: Generic category for specialty compounds that don’t fall under caulk but offer sealing properties. Used in niche or manufacturer-specific applications.
  • Silicone: 100% waterproof and highly flexible, ideal for kitchens, bathrooms, and exteriors. Bonds to non-porous surfaces like glass, tile, and metal.
  • Waterproof Paste: Dense, non-shrinking formulation used for filling or sealing areas with constant water exposure. Ideal for roof patching or leak repairs.

Caulk & Sealant FAQ

How quickly can caulk and sealant be delivered across Los Angeles?

Caulk and sealant can be delivered across Los Angeles the same day, often within four hours when in stock. Supply Ontime also offers scheduled two-hour delivery windows to match project timelines. Delivery options include Truck Bed Delivery, Curbside Delivery, and White Gloves Delivery, ensuring supplies arrive exactly where they’re needed without delays.

What types of caulk and sealant are available for delivery in Los Angeles?

The types of caulk and sealant available for delivery in Los Angeles include acrylic latex, silicone, polyurethane, epoxy, and specialized gutter sealants. Each has a specific application—such as interior drywall seams, exterior weatherproofing, sealing metal joints, or withstanding high heat and moisture. Products are sold individually for small projects or in bulk contractor packs for larger-scale jobs.

Should I use silicone caulk or polyurethane sealant for my Los Angeles project?

You should use silicone caulk when flexibility and waterproofing are needed, such as in bathrooms, kitchens, and other moisture-prone areas. Polyurethane sealant is a stronger option for heavy-duty applications like concrete joints, driveways, and structural work. In Los Angeles, homeowners typically rely on silicone for indoor projects, while contractors prefer polyurethane for outdoor and industrial jobs.
