Customer Reviews for Frost King 5/8 in. x 20 ft. Polyurethane Caulk Saver

Great backer for caulk and sealants. It greatly reduces the amount of caulk or sealant you need to apply into a gap or crack. This backer saves you a lot of money and hassle. Just shove it in a crack you are filling or in a window/door gap. Its not just a backer, it provides some insulation too. Easy to cut and use, I highly recommend this for caulking and filling big cracks. I most recently used this large size when filling a 1/4" to 1" thick crack between my from porch and the walkway.

This is a great product to fill cracks and space. I was looking around the Home Depot "windows" isle to fix my air leak under the window frame and ran into this item. I liked the idea and bought it to give a try. It was easy to install, and the air leak has been completely stopped.

I use this to fill in gaps for a log home due to natural separation between the logs. It does a great job insulating and has lasted for years.

The Frost King caulk saver does exactly that. It fills gaps to support the caulk in large spaces. This allows faster drying and less shrinkage.

Used it for an alternate purpose, as a draft stopper for my screen door. It worked great and I have a lot left over for other projects.

Good for filling/ backing the openings in-between components in the basement

Used this before and it's excellent

Used it to fill gap between a cabinet shelf and warped plywood back.

Not really soft, but has reasonable amount of give to it. The firmness allows it to fill cracks nicely. Used it to fill a large gap under a door threshold and followed up with silicon sealant...preventing me from having to fill the whole gap with sealant. Worked great.

I purchased this to make sprinkles on my outdoor decorative Christmas cupcakes. Worked really well.

This Front King Caulk Saver is a caulk king. It goes in nice and tight and even withstood being shoved in with a screwdriver. It's easy to cut and work and was super cheap. Highly recommend it!

This product worked great for my application. I was installing water proof laminent flooring and wanted to seal the edges. This foam will prevent water penetration and allow expansion of the flooring. There also was cold coming in front the space at the front of the house (outside wall). The foam also stopped this draft.

I found the caulk myself. But thanks to a helpful associate in customer service we were able to locate distilled water which was hidden behind some boxes.

Made easy my job good product.

great product to fill gaps. much easier & cleaner than foam

Just what I needed to fill a large gap between my foundation and vinyl sliding glass door frame before topping it off with self-leveling sealant

I'm a landlord and used the product to fill the gap between a fixed door and an adjacent space. Did the job.
