Frost King B2WT 19 oz/90' Mortite Caulking Cord, Woodtone

I had floor-to-ceiling gaps on both sides of my stone fireplace where it met my wood-paneled walls. The gaps ranged from 1/16” to 1/4” wide. The gaps never bothered me until I saw a roach exit the gap on one side of the fireplace, zip across the stone, and then disappear into the gap on the other side. Yuck, can’t have that. A few knowledgeable people advised me to apply a clear silicone bead, but I was reluctant because I figured I’d mess it up somehow and then I’d be upset that it didn’t look good.It was sheer serendipity that I came across this product while wasting time on Amazon. The product is 90’ in length made of 8 strips across that can easily be pulled apart. In my case, I peeled off a 3 strip section (which is approximately 1/2” wide (depending on how you squish it) and, starting at the ceiling, worked my way down, using my fingers to push the product along the gap and over and around the stone (the gap is very bumpy and uneven). The biggest issue I had was holding the big roll as I rolled it down the wall. In the end, I was very happy with the seal, the overall look, how easy it was to do, how unmessy it was to work with, and the brown color that complements the paneling.I attached a photo of what it looks like up close. It actually looks much better in person because the caulk lies in recessed corners on both sides of the fireplace; it just looks like dark corners without all the detail of the up-close photo.- Easy to remove? Yes, in the beginning and for at least 1 year (in my experience). I don’t know how easy it is to remove when it dries out over time.- How long will it last? I don’t know. So far, it’s been 1 year and it’s still adhering and still looking good.- Will it damage the wood paneling? I don’t know. I guess I’ll find out whenever it deteriorates enough that I have to remove it.- Will it leave residue on the stone? See answer above.I’m thinking I should probably remove it before it hardens and re-bead the gap with fresh product. For the price, ease of use, and color, it was a good solution for my problem. I think it probably looks better than the silicone would have, too.___________________________Update: December 2024 (6 years after putting up the product):A small portion (about 2 ft starting at the ceiling) of the caulk fell off, but the rest is still holding fairly well. I can tell it's dry in places because there's slight movement in places down the bead. So, I replaced the bead on once side of the fireplace and will eventually get around to doing the other.Thus, it held up for a solid 6 yrs. I don't know if that's good or bad, but it seems decent to me. The caulk did not damage my wood paneling, did not damage the stone of the fireplace, did not leave any residue anywhere, and was easy to remove.

I’m using it in my windows, works great easy to apply. I recommend it.

Very easily molded into the cracks you want to fill. I use this gray color around the stone fireplace. I really wanted a wood tone brown, but the brown they offer is very dark. I wish you came in different shades of brown.

I love this stuff!!!I used it to seal up 3 of my 103 year old windows (the worst ones out of the 9 i have)I am no longer getting horrible drafts in my living room! And more importantly i am no longer getting ladybugs constantly coming in my living room windows through the gaps in the shrunken wood of my poor ancient wooden windows.I was soooo tired of them flying around in my light fixtures in the evening and night bouncing off of the shades and bulbs over and over and over again!And a bonus is i will have far far fewer bugs in general find their way inside my house come spring. Hallelujah!!!I fully sealed one of my windows that i plan on never opening and temporarily sealed 2 of my windows that i do plan on opening come hot weather. I should have no problem removing this stuff once i need to. It's awesome!!!I highly reccomend it!!!*update*this stuff is still as awesome as the day i bought it!It removes fully and cleanly and is re-useable if you kneed it in your hands and then roll it into a snake! (Gotta kneed it in your hands if it's been a long while, because it gets a bit crumbly when you try to press it back on otherwise. Kneeding it in your warm hands re-activates the oils in it that make it flexible)

Its been a year since I applied this to various areas around my Trex deck and up against my stucco exterior walls. Noticed in early summer it almost all pulled away and was no longer 'leak' proof. Great idea, but maybe not where I live - 7500' in the mountains of Colorado. Think snow and winter!

This item was a waste of money, it is not anything that it states it does! Overall terrible, it should be taken off the market.

Seals air leaks well!

Bought this on the recommendation from my sister. Was not going to buy it based on reviews but after reading some of them I realized some were silly to me. Especially the one where the lady says it's sticky....hmmm....it's supposed to be like that. I bought 2 becausecI knew that the 90 feet was for one skinny strip. And I mean skinny. So I used 3 skinny strip to caulk my front door to stop the cols air from coming in. It works as it should. I use to take it but it would take Tha paint off in spring. We don't use the front door in the winter. Yes it's sticky but thays good so you can squeeze it ever so slightly into the gap. I recommend this to anyone just be sure you buy enough. I only used the one box on front door and will put away the other till next year. Enjoy!!!
