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

AMES Blue Max is a liquid rubber waterproof coating built for jobs where you need a durable, flexible membrane rather than a thin paint-like seal. This 5-gallon container covers up to 500 square feet and goes on with a brush, roller, or sprayer, so it works whether you're tackling a small foundation patch or a full basement wall. The blue liquid rubber formula is low VOC and rated for indoor and outdoor use, making it a fit for foundations, basements, planters, roofs, and other areas exposed to standing water or moisture.

Apply it between 50 and 90 degrees for proper cure. Plan your schedule around the dry time: 24 hours before recoating, with full cure at one day. It's not UV resistant, so it's best suited to below-grade or covered applications rather than surfaces left in direct, prolonged sun. Made in the USA, this is a job for anyone dealing with water intrusion who wants a rubberized barrier instead of a standard masonry sealer.

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.
