You can apply it in the winter and pull it off in the spring. It is so cheap, but I have also saved thicker strips for re-use by storing in a baggy and then using them in the out of the way places like a cellar window where I am not so concerned about the look of it being patched together. You can't beat this stuff for the price! **Q: Can this be applied outside in cold temps (20F or below)?** A: Yes, you can apply it if the temperatures are 20F or below. Please note that you need to divide the sections so that you have only the width that you need. Then you need to push it INTO THE SPACE OR INTO THE CRACK for it to stay in place. **Q: 5.5 x 5.8 x 1.2 inches? These dimentions don't even come close to the photo or a 45 foot roll. anybody have a clue?** A: Roll has 8 single strings of caulk which are rolled over and over again but are attached like licorice strings. It’s a lot and I have a 90 ft roll. The strings are a little thin an 1/8 of an inch in diameter x 90 ft long but they work. **Q: I have sliding windows, and patio door. Will the grey work good to seal the drafts on them?** A: Absolutely! I wasn't sure how good it was going to be so I ended up ordering more. I bought the wood - colored one as well to put on places where wood meets the sill, as I could feel air seeping in. I can't say how great this stuff is. I've got it on all my windows. It's very easy if you need to adjust it and taking it off is a breeze. You can peel it off in whayever is needed....thin, medium or thick pieces. It's inexpensive as well! I needed to write this review for you because I believe when you're going to buy a product...it's nice to hear from someone who has used it if it's good or not. Again, great great product and price!! ## Frequently Bought Together - Weatherstrip, 45 ft, Gray - Frost King V73/9H Indoor Shrink Window Kit 42 62-Inch, Clear, 9-Pack - Frost King R338H Self-Stick Rubber Foam Weatherseal, 3/8"W, 3/16"T, Black|Blacks --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/13303845-f4-mortite-caulking-cord-45-feet-long-9-1-2](https://www.desertcart.sn/products/13303845-f4-mortite-caulking-cord-45-feet-long-9-1-2) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-02*
