Top picks just for you
It is easy to use and flexible to seal the air leaks.
It's quite adhesive and has a pliable texture similar to airy playdough. It may require a bit of manipulation to achieve your desired consistency, but it's manageable. After using it, you'll want to wash your hands due to its stickiness. However, it excels at creating effective seals and is ideal for both construction and DIY projects.
The mass becomes dry after approximately 24 hours and cannot be perfectly molded at the end of this period.
So much nicer than the spray foam.
I found this product to be a handy and effective solution for a range of sealing and repair needs.
I've never encountered or utilized something quite like this before. While I'm familiar with putty and spackle separately, this product seems like a blend of the two.
I quickly received the order and now need to test the material. It seems to be of good quality and I believe it will perform well when used. The delivery was prompt, and the seller is reliable.
