Easy to apply and clean up, it prevents moisture-related deterioration while allowing for paint customization, making it the go-to choice for durable, eco-conscious home protection. ## Description ChimneySaver Water-Base is a penetrating, V.O.C. compliant, brick and masonry sealer which contains a proprietary modified siloxane. This water-based siloxane penetrates masonry up to 1/4 inch or more depending on surface porosity and moisture content at the time of application. ChimneySaver reacts with the minerals in masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process allow ChimneySaver Water-Base to become an integral part of the substrate and provide long term protection from leaks and water damage. ## Features - Water-Based Formula: Our water-based formula ensures a safer and more environmentally conscious application. - Prevents Water Damage: ChimneySaver Water-Base forms a powerful barrier, preventing water penetration and protecting your chimney from moisture-related issues such as cracking, spalling, and deterioration. - Long-Lasting Protection: With its advanced formula, this waterproofer provides long-lasting protection against water intrusion, ensuring the longevity and structural integrity of your chimney. - Easy Application and Cleanup: Applying ChimneySaver is a breeze. Its user-friendly application process allows for quick and hassle-free coverage. Cleanup is easy with soap and water, saving you time and effort. - Paintable with Oil-Based Primer: If desired, you can easily paint over this sealant with an oil-based primer, allowing for customization and seamless integration with your chimney's aesthetics. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KF3RKX2 | | Best Sellers Rank | #349,756 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,016 in Hardware Sealers | | Brand Name | ChimneySaver | | Color | clear | | Compatible Material | Masonry | | Customer Reviews | 4.7 4.7 out of 5 stars (3) | | Global Trade Identification Number | 00709057000604 | | Included Components | ChimneySaver Water-Base Waterproofing Sealer (5 Gallon) | | Item Form | Liquid | | Manufacturer | SaverSystems | | Material Type | Masonry | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 300031 | | Style Name | 2.5 Gallon | | Supported Standards | V.O.C. compliant | | Surface Recommendation | Masonry | | UPC | 709057000604 | | Unit Count | 320 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** ChimneySaver - **Item Form:** Liquid - **Material:** Masonry - **Style:** 2.5 Gallon - **Water Resistance Level:** Waterproof ## Images ![ChimneySaver Water-Base Waterproofing Sealer (2.5 Gallon) - Image 1](https://m.media-amazon.com/images/I/31JHTPP8iGL.jpg) ![ChimneySaver Water-Base Waterproofing Sealer (2.5 Gallon) - Image 2](https://m.media-amazon.com/images/I/51qX5DPgiyL.jpg) ![ChimneySaver Water-Base Waterproofing Sealer (2.5 Gallon) - Image 3](https://m.media-amazon.com/images/I/51CLa82TUDL.jpg) ![ChimneySaver Water-Base Waterproofing Sealer (2.5 Gallon) - Image 4](https://m.media-amazon.com/images/I/51EQW-lBa5L.jpg) ![ChimneySaver Water-Base Waterproofing Sealer (2.5 Gallon) - Image 5](https://m.media-amazon.com/images/I/51UrpIQyNAL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - ChimneySaver Water-Base Waterproofing Sealer (5 Gallon) - FlashSeal Elastomeric Flashing Sealant, 1 Gallon (Black) - ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon --- ## 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.be/products/46624489-chimneysaver-water-base-waterproofing-sealer-2-5-gallon](https://www.desertcart.be/products/46624489-chimneysaver-water-base-waterproofing-sealer-2-5-gallon) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-29*
