What Customers Are Saying

Customers overwhelmingly praise this product for effectively sealing air gaps and reducing drafts around windows, doors, and other openings, with many reporting measurable energy savings and lower utility bills. Reviewers consistently highlight its ease of use—requiring no tools, leaving no residue, and remaining reusable year after year. The ability to mold it by hand to irregular shapes and peel it off cleanly without damage is frequently cited as a major advantage. Most find it superior to traditional caulking and weatherstripping. A few note that strand separation can be time-consuming due to thick indentations, and some report inconsistent adhesion in certain applications, though these concerns remain minor among overwhelmingly positive feedback.

A good product that has many useful applications

Would Recommend

A versatile product that can be used for improving insulation, filling larger gaps prior to caulking or closing gaps in siding to prevent insects from settling in. This is a spool of 4 independent beads that can be seperated or combined as needed.

Don't waste your time or money.

Would Not Recommend

This caulk is horrible. It is not pliable at all, breaks when you try to seperate the threads or try to unroll any length at all. It doesn't want to mold into crevices no matter how much you press it in. It is dry and flimsy. Bought because Lowes was out of the normal brand that I use every year.

Cheap way to fill gaps or strangely shaped holes

Would Recommend

I had some areas where the gap is too complicated to fit a caulking gun or foam insulation. It worked great, and I can no longer feel the cold wind coming in. It has the consistency of slightly sticky modeling clay. They say you can use it indoors and out, so I might try it where the patio roof meets the bricks, as well. I tried it where the front door has gaps, too, but that didn't work. The door wouldn't lock anymore.

Very dependable and reusable.

Would Recommend

I like this product because it can be shaped and molded to the size and shaped to cracks that you want to cover. It can be easily removed and reused.
