In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Introducing OSI Quad Max Slate Gray Elastomeric Polymers Caulk Sealant in a 9.5 fl oz cartridge—a purpose-built solution for sealing that combines durability, paintability, and versatility for both indoor and outdoor projects. This is the sealant you reach for when you need a dependable, flexible barrier that looks right on every surface.

  • Moisture resistant seal to help keep out water and drafts around windows, doors, siding, and trim.
  • Paintable finish lets you color-match to your surfaces for a seamless, professional look.
  • Elastomeric polymers formulation delivers stretch and recovery to accommodate typical building movement without cracking.
  • Indoor and outdoor use—a single sealant that handles everyday conditions across rooms, patios, and exteriors.
  • Cartridge packaging fits standard caulk guns for clean, precise application.
  • Coverage approximately 29.1 sq ft per cartridge, making it practical for medium to larger projects.
  • Color slate gray blends with gray siding, trim, and fixtures for a cohesive finish.
  • Not designed for high-heat or fire exposure—best suited for typical residential sealing tasks that don’t reach extreme temperatures.
  • Not mildew resistant—in damp environments, prep and ventilation are important to maintain long-term performance.

Who should consider OSI Quad Max slate gray? Homeowners tackling window and door gaps, exterior joint sealing, or renovation jobs where a paintable, flexible sealant matters. It’s ideal for projects where you need a durable barrier that can be painted to match, without committing to a specialty silicone product. If you value a single, adaptable caulk that handles movement, moisture, and appearance in one package, this Quad Max sealant is designed to deliver real-world results.

Pro tips for best results: clean and dry surfaces before application, apply in moderate conditions, and back roll after tooling to ensure a smooth bead. Remember, while it provides moisture resistance and paintability, it’s not intended for high-heat environments or areas where mildew resistance is required.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
