Like is recommended with FlashSeal?** A: Are you talking about the mesh material. First cut your pieces or have a pair of scissors I find her easier to use. Get a cheap paint brush take your time paint above flashing onto the brick above the flashing and lay the mesh over. You got about 10-20 seconds to play with it …after that she gets hard to work with, and you’ll make it look worse. If you need to do a second coat wait until it dries then go back and put a second coat. If you try to go back and add more before it’s dry you’ll just mess it up. This is the type of information it takes years to acquire through trial and error. if you don’t do it right, it’s a pain to remove and then you’re really getting into a sticky situation. So recap. Depending on the size of the chimney, and I would do med/ large sections at a time. I have your pieces ready put your first coat on lay you mesh pieces and make sure you put your second coat thick enough that you can’t see the mesh. ## Frequently Bought Together - MasonryDefender Chimney Flashing Sealer - Flexible Coating That Protects Chimney Flashings from Water Leaks - MasonryDefender Chimney Crown Sealer - Brushable Sealant Fixes Cracked Chimney Tops & Prevents Chimney Leaks - MasonryDefender Chimney Brick Sealer, Clear Water-Based Siloxane Sealer - Breathable Waterproofer for All Exterior, Vertical Masonry Surfaces - 1 Gal --- ## 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.co.il/products/238713604-chimney-flashing-sealer](https://www.desertcart.co.il/products/238713604-chimney-flashing-sealer) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-06-19*
