Living in the Pacific Northwest, where rain is a constant, our patio and driveway were constantly getting soaked and stained. After applying this Silane Siloxane-based sealer, the difference has been remarkable. Water Repellency & Protection: The sealer is incredibly effective at creating a deep, penetrating barrier that prevents water from soaking into the concrete. After application, I noticed that water now beads up and rolls off the surface, even with the heavy, consistent rains we get here. It's like our patio has a protective shield against moisture, which not only keeps the surface dry but also prevents potential damage from water infiltration, such as cracks and discoloration. Easy to Apply & Long-Lasting: Applying the sealer was straightforward, and the 2.5-gallon size was more than enough to cover our entire patio and driveway. It dries quickly and doesn’t leave any sticky residue or odd finish—just a smooth, invisible protection that doesn’t alter the appearance of the concrete. I’m confident it will provide long-lasting protection for our surfaces, especially during the wet months when they are most vulnerable. Great for Concrete Pavers: We also have concrete pavers in our backyard, and this sealer has been fantastic for them as well. The pavers no longer absorb water, which means no more staining or deterioration from rainwater. Overall: I’m thoroughly pleased with the MasonryDefender Concrete Sealer and would highly recommend it to anyone in the Pacific Northwest (or anywhere with a lot of rain) who wants to protect their concrete and pavers. It’s an excellent investment to keep your outdoor spaces looking great and standing up to the elements year-round! Review: Impressive results that last - I am going on the third year after treatment of my driveway and I am very pleased to report the protection is still there and has made a remarkable difference. I have a long fibre-crete driveway in SC. The summers are long and hot and there is intermittent rain. The finish job on my concrete was never pretty to begin with so the surface is rougher than I would have liked which leads to shading and surface inconsistencies, pockets for water to collect which leads to mold growth and dirt collection. Not great. I decided to seal a bunch of test areas on the driveway to see if that would help. I applied 5 gallons of this product 2 summers ago. I stuck to doing entire driveway squares so it wouldn't look ridiculous. Now going on my 3rd year you can still see the marked difference in the way that the treated squares of concrete repel dirt and mold due to accumulating water. The photos I included show the difference between treated and untreated areas. Keep in mind my concrete has always looked very shaded due to the way it was finished in the first place so don't judge the results by this ugly shading -that's just part of my concrete. This product didn't cause any additional shading. If anything, it lessened the visual impact of the original shading in the concrete. For sure every square that I have treated is much whiter and cleaner looking than the untreated squares. More like what it looked like immediately following the power washing that I did prior to application 2 years ago. I will treat the remaining squares this year and then reseal the original test squares. Great product. ## Features - CLEAR PROTECTION FOR CONCRETE: This clear penetrating concrete sealer provides invisible, non-glossy protection for driveways, sidewalks, and patios without changing color or appearance. - WATER REPELLENT TECHNOLOGY: Advanced silane siloxane concrete sealer bonds with surfaces to repel water, causing moisture to bead and roll off while allowing concrete to breathe naturally. - DURABLE OUTDOOR DEFENSE: Protect your driveway from pitting, cracking, ice melt salts, chloride ions, freeze-thaw cycles, and efflorescence stains with this long-lasting concrete sealant. - EASY APPLICATION AND COVERAGE: Clean concrete thoroughly before use. Apply with a low-pressure garden sprayer for even coverage. One gallon covers 90-150 sq. ft. for reliable outdoor sealing. - BREATHABLE PENETRATING FORMULA: This siloxane concrete sealer penetrates deep into pores, blocking water infiltration without forming a surface film, keeping your driveway protected and breathable. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076DB2LBY | | Best Sellers Rank | #28,776 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #109 in Hardware Sealers | | Brand | MasonryDefender | | Brand Name | MasonryDefender | | Color | clear | | Compatible Material | Concrete | | Customer Reviews | 4.4 out of 5 stars 911 Reviews | | Item Form | Liquid | | Item Weight | 9 pounds | | Manufacturer | SaverSystems | | Material | Silicone | | Material Type | Silicone | | Number of Items | 1 | | Part Number | 300550 | | Style | Bead,Protection | | Style Name | Bead,Protection | | Surface Recommendation | Concrete | | UPC | 709057000307 | | Unit Count | 128 Fluid Ounces | | Water Resistance Level | Water Repellent | ## Product Details - **Brand:** MasonryDefender - **Item Weight:** 9 pounds - **Material:** Silicone - **Style:** Bead,Protection - **Water Resistance Level:** Water Repellent ## Images ![Concrete Sealer - Deep Penetrating Water Repellent, Silane Siloxane - 1 Gallon - Image 1](https://m.media-amazon.com/images/I/61-3gBUh8NL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this product go over another brand of sealer?** A: I did and have seen no negative effects, but I have been disappointed in the product in that rain does not bead up as on other dealers. **Q: Does this prevent berries and leaves from staining the concrete?** A: The concrete driveway sealer is designed to prevent long term deterioration from water damage and de-icing salts. It prevents water from from penetrating the concrete while allowing the concrete to breathe. Like any surface it is important to clean up sources of possible stains to prevent discoloration **Q: is this sold in local big box stores?** A: No. Only from the web. **Q: I applied this to my concrete patio last year. Can I apply it again this year without stripping the previous coat off (I will power wash first)?** A: I have in the past applied the year after the initial coat. It seemed to work well. I would not use a power washer, however, since that might strip the previous year's coat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Concrete and Pavers in the PNW Rains *by J***W on December 28, 2024* I recently used MasonryDefender Concrete Sealer on our concrete pavers and patio, and I couldn’t be more impressed with the results.

Cement steps looked the same as after cleaning them before application. Water beads up nicely after rain. ## Frequently Bought Together - MasonryDefender Concrete Sealer for Driveways, Patios, & Sidewalks - Deep Penetrating Water Repellent Protection - Silane Siloxane Sealer - 1 Gallon - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - MasonryDefender All-Purpose Masonry & Concrete Cleaner, 2 LB Pail - Cleans Driveways, Sidewalks, Patios, Garage Floors, Pavers & More --- ## 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.tn/products/72166533-concrete-sealer-deep-penetrating-water-repellent-silane-siloxane-1-gallon](https://www.desertcart.tn/products/72166533-concrete-sealer-deep-penetrating-water-repellent-silane-siloxane-1-gallon) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-05*
