It's unlike any caulk I have used. Very durable and water resistant. Can't paint over it for about 48 hours in my opinion but once it's down it's there for good. I repaired several loose and crumbly panels on a garage door primed and painted it. Now it's as good as new. Also troublesome windows that were leaking with every other kind of caulk after the sun baked it for a year so. This put an end to it. It can be tooled by the way. I've seen videos that say it can't. But it certainly can. ### ⭐⭐⭐⭐⭐ Best sealant for Hardie board *by T***F on April 30, 2024* I had to replace some Hardie plank on my house and looked up what was recommended by the OEM for sealant and OSI Quad Max is what Hardie recommends.If you want a sealant that is not going to let go and last a long time - this is it. ### ⭐⭐⭐⭐⭐ Bought cause my contractor used it *by A***R on May 30, 2023* Recently had some windows installed and this tuff kept its shape and shines months later. So I bought some to redo some others windows at another house that were done 5 years ago. Looking forward to great results with it long term. ## Frequently Bought Together - 3 Pack OSI Sealants 9.5 oz Quad Max Window, Door and Siding Sealant, White - ALLWAY CT31 3-in-1 Caulk Tool for Removal and Application - Newborn Octogun 930-GTD Drip-Free Caulking Gun - Gator Trigger Grip | Fits 1/10 Gallon Cartridge |10:1 Thrust Ratio | Smooth Hex Rod Cradle with Built-in Smoother Tool | Scraper & Plug Included --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/444857563-3-pack-osi-sealants-9-5-oz-quad-max-window](https://www.desertcart.ma/products/444857563-3-pack-osi-sealants-9-5-oz-quad-max-window) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-04-26*
