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

About Product Overview

DRYLOK Masonry Waterproofer is a latex-based coating built to stop water intrusion on concrete, both above and below grade. This 5-gallon container covers 375-500 square feet, making it a practical choice for basement walls, foundations, retaining walls, and other masonry surfaces that take on moisture year-round.

The flat gray finish goes on with standard tools and cleans up with just soap and water, no solvents required. It's rated for indoor and outdoor use, so the same product handles an interior basement wall and an exterior foundation. Recoat in as little as 3 hours, with a full cure at 24 hours, so you can get through a job in a day rather than stretching it over a weekend. It also has stain-blocking properties, useful on masonry that's already showing water marks or mineral deposits.

This is not a tintable product, so plan on the gray finish as-is. Good fit for homeowners tackling a damp basement or contractors waterproofing foundations and retaining walls where reliable coverage per gallon matters.

  • Coating material: Latex, flat sheen, gray
  • Recoat time: 3 hours; full cure: 24 hours

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.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

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 familiar 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.
