Features

  • BROAD TEMPERATURE RESILIENCE: Donseal PU440 Polyurethane Caulk operates effectively across a temperature range of -22F to 175F, 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.

  • Solid durable adhesive sealant
Color: Grey Number of Items: 1
Used it around the Freon line coming through the foundation. Applied it last after wrapping the pipe in copper mesh . I think it sealed up very well and will keep the varmints out! Very high quality. Highly Recommended

  • Best Sealant on the Market
Color: Grey Number of Items: 1
After testing multiple brands, this is without question the most reliable and best-performing sealant I’ve found. Nothing else has given me the same level of confidence and results. Easy to apply, excellent adhesion, and outstanding durability. I highly recommend it to both professionals and DIY users. 100% recommended!! ... show more

  • Unuseable due to defective material
Color: Grey Number of Items: 2
This stuff was unusable. Both tubes were virtually solid and I could not get any of the sealant out. I even used a meat skewer to poke bigger holes in the gasket but no luck. Bottom line - I consider this to be a complete ripoff.
