## Overview

AMES Blue Max White Liquid Rubber Waterproofer is a high-performance, elastomeric coating that stretches 900% to create a durable, waterproof membrane on concrete, wood, metal, and more. Non-toxic and VOC compliant, it’s ideal for below-grade foundations, basements, and other wet environments. Made in the USA by a veteran and woman-owned company, it offers professional-grade adhesion and flexibility to protect your surfaces from cracking, peeling, and water damage.

## Description

Ames' Blue Max is a special blend of adhesive, high strength elastomeric liquid rubber for waterproofing basements. It is a new, impenetrable, rubber technology for waterproofing in extreme wet situations such as below grade foundations, basement walls, and cisterns. It is high in solids and dries to a tough 800% elastic membrane that resists cracking and peeling. Blue max remains flexible in freezing temperatures. Ames' blue max is impervious to water when applied in a uniform and seamless fashion with adequate millage. It flows into cracks and crevices as a liquid and sets up as a durable rubber to seal leaks wherever they occur. Ames blue max is uv sensitive and must be top coated if exposed to sunlight. Ames' blue max is also an excellent coating for icf (insulated concrete forms), as well as metal, wood, concrete, and many other applications. The adhesive qualities in Ames' blue max actually glue surfaces together and strengthen wall construction. Ames' blue max outperforms isocyanate urethanes, and works well as a primer and waterproofing membrane for Ames' products. Ames' blue max must be top coated for uv protection in exterior applications.

Review: Durable strength & Waterproof Coating - Wow, what a great coating to support my underlayment cement board. The elasticity and water proof quality provides extra added durability to the cement board. One coating is great -2 would even be better.
Review: Good roof primer! - This served as a primer for an elastomeric coating, over a weathered modified bitumen roof. It's important that you clean the surface first with a soft wash or light pressure wash to get rid of any accumulated gunk that may block adhesion. But once you've got a dry & clean surface, this stuff sticks like, well, glue. I laid down two coats several days apart. It dried / cured fairly quickly, so I was able to walk on it after 24 hours (after each coat). Rain doesn't seem to hurt it after it's had a few hours of initial cure time. Just get it good and dry before re-coating. I'm now finish coating it with AMES Elastomeric white roof coating, with good results so far.
