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.

    • Check to see if caulk is dried and unusable.
Check it as soon as you get it. I didn’t and found the caulk to be dried and unusable. I received it August 13 and didn’t try to use it till mid October. The expiration date on the tube was 04-20-2026.

Update!**** company reached out and refunded me, very impressive. I really appreciate that. Quality product, plus quality company. 5 stars The product seems great, would have been 5 stars if both tubes were good. One was solid and already set up in tube. So I was only able to use one tube.

    • Didn’t fit.
I had no idea that there were different sizes of caulk tubes. These were too big for my gun but I didn’t realize that under both tubes and my gun were destroyed by my efforts. My fault, not the company’s. Just writing so others will know.

    • They came cemented in the tubes - huge waste of money.
Came seized up in the tube - completely unusable.

I've used it to seal my metal garage between the concrete and the metal, it looks like it does the job, now let's see if it last.

    • 10.1 oz tube doesn’t work with all caulk guns.
EASY APPLICATION: This product is packaged in a 10.1 fl. oz. cartridge for use with any standard caulk gun, This is not true, I have two “standard” caulk guns, the tube fit in as normal but attempting to screw on the large application nozzle is interfered with by the caulk gun end, results in a connection that cannot get tight enough to seal around the nozzle, resulting in a product that cannot be used. ... show more
