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

Meet a sealant that adapts as your space does: the OSI Quad Max Iron Gray Elastomeric Polymers Caulk Sealant 9.5 oz cartridge. Designed for both interior and exterior jobs, this sealant stays permanently flexible, accepts paint, and resists moisture and mildew—perfect for gaps that see seasonal movement and humidity alike.

  • Elastomeric polymer technology delivers lasting elasticity, so joints move with expansion and contraction without cracking or losing adhesion.
  • Moisture resistant and mildew resistant formula keeps seams sealed in bathrooms, kitchens, basements, and exterior areas subject to rain and humidity.
  • Paintable finish lets you blend the seal with walls, trim, or metal surfaces after it cures for a seamless look.
  • Permanent flexibility ensures durability over time, reducing the need for frequent re-sealing in high-traffic or weather-exposed locations.
  • Indoor and outdoor use with a versatile iron gray color that complements darker trims, metal, and masonry finishes.
  • 9.5 oz cartridge provides ample material for longer runs and bigger projects, with a coverage area listed at 29.1.
Ideal uses and scenarios
Why this sealant stands out

Unlike rigid caulks, this Quad Max variant combines durable moisture resistance with reliable elasticity, ensuring a lasting seal in challenging environments. The iron gray color helps the product blend with metal finishes and darker framing, making repairs less conspicuous while delivering a clean, professional appearance.

How to use (quick guidelines)
  • Prepare joints by cleaning away dust, oil, and old sealant; ensure surfaces are dry before application.
  • Cut nozzle to desired bead size, load into a compatible caulking gun, and apply a steady bead along the seam.
  • Tool or smooth the bead with a caulking tool or damp finger for a clean finish.
  • Allow the sealant to cure according to the package directions before painting or exposing to use. If painting, apply after cure is complete.

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.
