Questions & Answers

Can this be used for filling expansion gaps on driveways?

No, too soft, foam cell type material. Will break down fast.

Can I use this product to fill an expansion joint with a 1/2" opening & about 1 1/2" depth around...

Can I use this product to fill an expansion joint with a 1/2" opening & about 1 1/2" depth around the outer perimeter of our pool, in which we also have to fill the top 1/2" of the opening with Deck O'Seal? Do you think we may need to put 2 layers of the 3/8" Caulk Saver to fill about 1" depth of the opening, before filling the top 1/2" with Deck O'Seal? Thank you.
Asked by: Goldie
The caulk is really for small gaps and openings in expansion joints. You may have too large an opening. I have seen 5/8" caulk saver.

Asked by: tj
You will be leaving a space between the wall and the flooring to allow expansion of the laminate flooring. It is in this space where the caulk saver will go and then caulk on the top of the caulk saver. Caulk allows the flooring to expand and keep out any water that gets left on the flooring. For example, wet boots, pets accidents. Used all around the room perimeter.

Can this be used to fill deep brick mortar joints and then caulked

Can this be used to fill deep brick mortar joints and then caulked
Asked by: wcwitherssr
Sorry for the late response. Hope you had success. I believe it can. I used it to fill the gaps between my exterior walls and the slab on the inside of the house (poorly constructed semi tract home.) I then used acrylic caulking to seal it in. It is quite sturdy.

I have filled the space in between the counter top and my range oven so that nothing will fall into the slot. It is also good for sealing the space when the window does not close tight and leaks air.

Rated 5 out of 5 by from Good buy I purchased this product to fill in larger gaps around my window siding before re-caulking and worked great and was easy to use. I just wish it was stocked at the store.

Rated 5 out of 5 by from Make sure you get the right size! If you've ever tried to push in a lot of caulk or cement crack... Make sure you get the right size! If you've ever tried to push in a lot of caulk or cement crack fillers, you'll know how many caulk tubes you have to go through. With the caulk saver, you'll be able to save a lot of caulk and I believe it makes the top layer of caulk last even longer and become stronger. You can stuff these but it may be better to "round down" since you can stuff it twice versus if you bought a bigger one, you can't stuff it. Most caulks I use tend to hold well to this.
