Sealant Stays Looking Clean, Fresh & New!

Helpful Tips

  • 1

    To ensure strong adhesion, make sure the area to be sealed is free of all old caulk, clean and dry. As a final step before applying new sealant wipe the seam with rubbing alcohol to remove residue.

  • 2

    The “secret” to straight edges: Prior to sealing, apply painter’s masking tape above and below the joint you’ll be sealing. Once you’ve finished, make sure to remove the tape while the caulk is still wet.

  • 3

    Need to seal in a tight space? For areas where it may be hard to navigate a caulk gun and cartridge, try using a squeeze tube. Squeeze tubes don't require a caulk gun and fit easily in the palm of your hand so you can get into tight spaces and corners. It's also great for smaller projects.

  • 4

    Caulking a shower? Work from the inside out. Seal the inside seams and joints before the external ones so you don’t brush up against any wet caulk and have to reapply the sealant.

  • 5

    Cut the nozzle at a 45º angle and load into caulk gun. Hold the caulk gun at a 45º angle to the surface and gently squeeze the trigger with steady pressure to apply an even and consistent bead of sealant to the seam. Move the caulk gun slowly and steadily, filling the joint with sealant.

    Want a professional-looking finish? After you’ve applied the sealant, “tool” or smooth the bead of sealant with a caulk finishing tool dipped in water.

Frequently Asked Questions

The new innovative, ultra hydrophobic technology of KWIK SEAL ULTRA™ repels water, dirt, stains and soap scum, so mildew can’t grow, stains won’t stick and dirt rinses off. If any dirt or scum collects on the sealant, it easily wipes or rinses away, without the need to scrub. However, regular cleaning of the surrounding area of the sealant is suggested.

No. The advanced repelling technology is built-in throughout the sealant and doesn’t wear or wash away over time.

Because of its innovative, ultra hydrophobic technology which repels water, liquids, dirt and stains, KWIK SEAL ULTRA™ cannot be painted. Most sealants used in kitchen and bathroom applications are not painted, so this feature should not be viewed as a negative.

DAP® KWIK SEAL ULTRA™ outperforms conventional acrylic latex sealants in many ways that are meaningful to consumers. The innovative ultra hydrophobic technology of KWIK SEAL ULTRA™ repels water, dirt, and soap scum, so the sealant stays looking clean, fresh and new. It has exceptional stain proof protection to resist the toughest stains. Latex sealants can’t do this and usually require scrubbing to clean away dirt, grime and soap scum. Difficult stains, such as mustard and grape juice can permanently stain latex sealants. Also, KWIK SEAL ULTRA™ is water ready in just 4 hours without washing out, unlike other latex caulks and sealants which require a 24-48 waiting period before exposing to water. And, KWIK SEAL ULTRA™ is the only sealant on the market today to offer a lifetime mold and mildew resistance guarantee.

DAP® KWIK SEAL ULTRA™ also outperforms silicone sealants in many ways. While silicone does repel water, it doesn’t repel soap scum and dirt and therefore can be difficult to clean and stay looking clean. Sometimes silicone requires scrubbing to remove soap scum, stains and other dirt. Silicones by nature also have an electrostatic attraction which attracts dust and dirt to the surface, making them dirty and hard to clean. Compared to acetoxy silicone, KWIK SEAL ULTRA™ is low in odor, so it is ideal for working in enclosed spaces, and is water ready in just 4 hours. Compared to neutral cure silicones, KWIK SEAL ULTRA™ has better stain resistance. Unlike both acetoxy and neutral cure silicone, KWIK SEAL ULTRA™ cleans up easily with soap and water versus mineral spirits; applies smoothly and easily versus being stringy; and doesn’t stain granite or marble surfaces. And, KWIK SEAL ULTRA™ is the only sealant on the market today backed by a lifetime mold and mildew resistance guarantee.

Yes, KWIK SEAL ULTRA™ clear applies white and dries clear in 7 days, just like other latex sealants. However, it still can be exposed to water in just 4 hours without washing out.
