AMES Blue Max 1 Gallon Liquid Rubber Waterproofer – Indoor & Outdoor Waterproofing

Meet AMES Blue Max, a high- solids elastomeric liquid rubber designed to protect basements, foundations, and other surfaces from moisture. This blue coating flows into cracks as a liquid and cures into a tough, flexible membrane that adapts to movement and temperature changes. Built to work on concrete, wood, metal, and more, Blue Max is a versatile waterproofing solution for both interior and exterior projects. It’s non-toxic and VOC compliant, made in the USA, and reflects AMES’ heritage as a woman-owned, veteran-founded company. Note that UV exposure requires a top coat for exterior applications to maintain color and durability.

Why choose AMES Blue Max?

• Superior waterproofing across above- and below-grade surfaces, walls, and foundations with seamless coverage.
• High elasticity (up to 1200% elongation) to resist cracking and peeling as surfaces move or freeze/thaw cycles occur.
• Excellent substrate versatility — bonds to concrete, wood, metal, and more, and can act as a primer for other AMES products.
• Flexible, rubber-like film that expands and contracts with the surface to maintain a protective seal.
• UV considerations: exterior use requires a top coat to protect against sunlight and extend life.
• Non-toxic, eco-friendly formulation and VOC compliant in all 50 states; proudly manufactured in the USA.
• AMeS as a brand note: the product is part of a company that is woman-owned and veteran-founded.

Where and how to use

• Basements, foundations, and below-grade walls where a seamless, impermeable layer is beneficial.
• Insulated concrete forms (ICFs) and other concrete, wood, or metal substrates requiring protection from moisture.
• As a primer and waterproofing membrane on roofs or structural surfaces where moisture resistance is desired.
• Versatile for interior or exterior applications, with multiple application methods available (brush, roller, or spray).

Application essentials

Blue Max is designed to flow into cracks and crevices, then cure into a durable rubbery film. For exterior uses, plan for a top coat to guard against UV exposure. The product is designed for uniform millage to create a continuous, seamless barrier and can bond surfaces to enhance wall construction when used as a coating or primer.

• Surface prep: ensure the area is clean, dry, and free of loose material.
• Application methods: brush, roller, or spray on vertical or horizontal surfaces for even coverage.
• Film behavior: elastomeric membrane that expands and contracts with the substrate to resist cracking.
• UV note: exterior uses require a UV top coat to maintain performance and appearance.
• Safety and origin: non-toxic formulation; VOC compliant; made in the USA; AMES stands for reliability and experience.

While Blue Max offers versatile waterproofing benefits, actual results depend on proper surface preparation, uniform application, and environmental conditions. It can serve as a protective layer on multiple substrates and, in some cases, may enhance wall construction with its adhesive characteristics. Consider your project needs, surface types, and exposure when planning your waterproofing strategy.
