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.

Concrete Sealants FAQ

Why should I seal my concrete driveway or patio in Los Angeles?

Concrete sealing serves as a protective barrier that stops water penetration, blocks stains, and protects surfaces from UV light exposure. The combination of strong sunlight and occasional rain in Los Angeles' weather leads to concrete deterioration through cracking and fading when surfaces remain unsealed. A high-quality sealer establishes a protective barrier that blocks moisture penetration while defending surfaces from harm and simultaneously improves their appearance through color enhancement and sheen addition. The process of regular sealing protects outdoor concrete surfaces including driveways, walkways, and patios from damage that leads to longer product life.

What types of concrete sealers are available and which is best?

The market offers four primary types of concrete sealers which include acrylic, silane/siloxane, epoxy, and polyurethane. Acrylic sealers serve two purposes by improving color appearance and offering budget-friendly protection for outdoor patio surfaces. The water-resistant properties of silane/siloxane sealers establish an invisible moisture barrier which delivers maximum protection for areas exposed to moisture. The chemical-resistant epoxy finish makes it suitable for garage applications because it delivers long-lasting protection. Polyurethane stands out as the best material for Los Angeles sun-exposed areas because it offers exceptional protection against UV rays and abrasion. The selection between these sealers depends on the amount of surface area you need to protect and your desired finish outcome.

How often should I reseal concrete surfaces in Los Angeles?

The frequency of concrete resealing depends on sealer type, exposure conditions, and traffic volume which requires reapplication every two to five years. The resealing process for driveways and patios in Los Angeles needs to happen every two years because of their exposure to sunlight and frequent usage. The resealing process needs to be performed when the color fades away and water stops creating droplets on the surface. Regular resealing protects concrete surfaces from expensive damage while maintaining their original appearance.

Can I order concrete sealants for same-day delivery?

Yes. Supply Ontime offers same-day delivery of concrete sealers and tools such as rollers and sprayers. The company delivers materials directly to construction sites across Los Angeles which helps contractors obtain their needed supplies at the correct time. The immediate availability of sealers allows project teams to stay on schedule while providing immediate protection for surfaces.
