About This

  • BROAD TEMPERATURE RESILIENCE: Donseal PU440 Polyurethane Caulk operates effectively across a temperature range of -22°F to 175°F, suitable for concrete expansion joints. Its moisture-cure process forms an elastic material, ideal for sidewalk applications.
  • MULTIPLE SURFACE COMPATIBILITY: Formulated for a wide array of substrates, Donseal PU440 can seal concrete, wood, gypsum, aluminum, steel, and ceramic surfaces. This makes it a versatile choice for DIY home projects, foundation and sidewalk tasks, offering reliable sealing across diverse materials.
  • VERSATILE USE: Donseal PU440 is suitable for use in dry, wet, and water-filled concrete holes. The polyurethane caulk offers a robust bond not only to concrete, but also to solid and hollow masonry, hard natural stone, as well as solid and porous rock. Once cured, it accepts both latex and water-based paints.
  • EASY TO USE: Packaged in a 10.1 fl. oz. cartridge for use with a standard caulk gun, allowing for smooth and consistent application. For enhanced efficiency and precision, consider using our new polyurethane gun, specially designed for optimal use with PU440. No pre-mixing required.
  • EXPIRATION-DATED PRODUCT: Donseal PU440 has a shelf life of 365 days from the manufacturing date. Both the manufacturing date (Prod.) and expiration date (EXP) are clearly printed on the product packaging to ensure proper usage within the recommended timeframe.

    ⭐⭐⭐⭐⭐

    "Saved me from an expensive plumbing repair"

    I discovered a small leak under my kitchen sink late at night.

    This repair tape was incredibly easy to apply and stopped the leak immediately.

    It held securely until I could arrange a permanent repair.

    A must-have item for every homeowner.

    ⭐️⭐️⭐️⭐️⭐️

    "Quick fix that actually works"

    I used this waterproof repair tape on an outdoor water pipe.

    The application took only a few minutes and the seal has remained strong through several rainstorms.

    It's durable, reliable, and much easier than I expected.

    I'm very impressed with the results.

    ⭐️⭐️⭐️⭐️⭐️

    "Perfect for emergency repairs"

    A pipe in my garage started leaking unexpectedly.

    This tape gave me a fast temporary solution without needing special tools.

    The adhesion is strong and the material feels high quality.

    Definitely worth keeping in a home repair kit.

    ⭐⭐⭐⭐⭐

    "Every DIY homeowner should have this"

    I purchased this for emergency household repairs and it exceeded my expectations.

    It sealed a leaking connection quickly and helped prevent further water damage.

    The instructions were simple and the product worked exactly as advertised.

    I'll be ordering another roll just to keep on hand.
