Its Sunburst brown shade blends seamlessly with wood tones and earth-inspired exteriors, while the elastomeric polymer technology delivers lasting flexibility that moves with the substrate without cracking or weakening. Key features that matter in real-life projects\n- Permanently flexible elastomeric polymer formula that accommodates expansion and contraction, helping joints stay sealed through temperature changes and daily wear.\n- Moisture resistant and mildew resistant, making it a dependable choice for bathrooms, kitchens, laundry areas, basements, and exterior surfaces where moisture is common.\n- Indoor and outdoor use with broad substrate compatibility, plus the option to paint after curing to achieve a tailored, cohesive look.\n- 9.5 oz cartridge designed for easy application with a standard caulk gun, delivering controlled beads and minimal waste.\n- Sunburst color from the brown family provides a natural, low-contrast finish that blends with trim, siding, and cabinetry.\n- Not fire-rated or designed for high-heat environments, so it’s best reserved for typical interior and exterior joint sealing rather than grills, heaters, or direct flame zones. Where to use it: practical scenarios and ideas\n- Around windows and doors to block drafts and moisture while maintaining a clean, finished edge.\n- Exterior siding and trim joints that face seasonal weather; the seal remains flexible as the building expands and contracts.\n- In bathrooms and kitchens around tubs, showers, sinks, and backsplashes where water exposure is routine.\n- Interior trim work—baseboards, crown molding, and other wooden details—for a paintable, seamless look.\n- Garage, basement, and utility areas where a durable, mildew-resistant seal helps protect against moisture intrusion. Why this sealant stands out\n- The combination of permanent elasticity and mildew resistance provides long-lasting performance where standard caulks might fail with movement or humidity.\n- Paintability gives you the freedom to achieve a precise color match after cure, reducing the need for masking or multiple coats.\n- The Sunburst color minimizes the need for frequent touch-ups on woodwork and exterior accents, letting you finish with confidence. Pro tips for best results\n- Prep surfaces by cleaning and ensuring they’re dry before application for optimal adhesion.\n- Cut the nozzle at a 45-degree angle to control bead size and achieve a clean, professional seal.\n- Smooth the bead with a damp caulk tool or finger to create a uniform finish that matches surrounding surfaces.\n- Allow sufficient cure time per package directions before painting or exposing to moisture or heavy use. This OSI Quad Max Sunburst 9.5 oz caulk sealant offers a concrete combination of moisture resistance, mildew control, paintability, and enduring flexibility, all wrapped in a color designed to complement brown-toned spaces—delivering a durable seal that looks as good as it performs.\u003c\/div\u003e","brand":"Osi","offers":[{"title":"Default Title","offer_id":52272838836498,"sku":"1044440","price":13.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/1024\/8466\/files\/1044440_A.eps_High.jpg?v=1778782878","url":"https:\/\/nationalhardwaregroup.com\/products\/osi-quad-max-sunburst-elastomeric-polymers-caulk-sealant-9-5-oz","provider":"National Hardware Group","version":"1.0","type":"link"}
