Where to Use:
It is designed especially for waterproofing in extreme situations

• Below-Grade Foundations
• Basement Walls
• ICF (insulated concrete forms)
• Metal
• Wood
• Concrete
• and Many Other Applications

The surface must be clean, dry, and free of loose material before the coating application. Power wash thoroughly, if needed. Brush, trowel, or caulk all cracks greater than 1/8” wide with Ames® Blue Max® Trowel Grade coating and filler. Always run a test patch first in an inconspicuous area. This is to ensure that there is proper adhesion and drying, and that the product performs to your satisfaction. No need to shake or stir. It comes ready to use straight out of the can. Prime all surfaces generously with Ames’® Block & Wall® Liquid Rubber.

Application by surface type:
When applied in a uniform and seamless fashion with adequate millage Block & Wall® Liquid Rubber is impervious to water. Block & Wall® Liquid Rubber has a slight tack when dry. It is UV sensitive and MUST BE TOPCOATED if used on exterior above grade. May topcoat walls with Ames’® Paint & Prime®. On below-grade exterior walls use plastic sheeting, or similar, for further protection of the coating from backfill. Block & Wall® Liquid Rubber is water impervious up to .016 perms.

Concrete Walls & Foundations
Fill all joints or cracks wider than 1/8inch with Blue Max® Trowel Grade filler. Surfaces with cracks, vents, or where two unlike surfaces come together, require Ames® Peel & Stick™ Seam Tape (PS250, PS450 or PS650) to provide some additional strength and reinforcement. First prior to setting the Seam Tape in place, apply a liberal topcoat of Block & Wall® Liquid Rubber or Ames® Blue Max® to the surface at the rate of one gallon per 100 sq. feet per coat and allow to cure. Apply Block & Wall® Liquid Rubber or Blue Max® over the seam tape and allow to cure. For a complete application we recommend two gallons per 100 square feet for walls. Block & Wall® Liquid Rubber can be slightly tacky and may be top-coated on basement walls with Ames® Block & Wall® Acrylic coating or Ames® Paint & Prime®. The following instructions are some suggested methods of application that may work for you on your waterproofing project.

Plywood, Underlayment, OSB Siding and Roofs
Use Block & Wall® Liquid Rubber as a vapor barrier on plywood, underlayment, O.S.B. siding and roofs. Block & Wall® Liquid Rubber penetrates and seals wood to a watertight condition. Seam Tape all joints and coat with 1 gallon per 100 square feet of Block & Wall® Liquid Rubber. Seam tape all seams before coating.

Sprayer Instruction:
If using a commercial sprayer, we recommend a 3/8-inch hose for commercial applications. Call us for specifications. For smaller applications apply by brush or roller.

Block & Wall® Liquid Rubber may be brushed, rolled or sprayed. We recommend two gallons per 100 square foot for walls. The application must be applied in a continuous, unbroken seal of a minimum dry thickness of no less than 30 mils (the thickness of a dime). Block & Wall® Liquid Rubber is a heavy duty, sprayable grade. It may also be applied with 3-4-inch paint brush, Commercial Airless Sprayer or a Roller and Handle. With a commercial sprayer, call for proper specifications.

Estimated Coverage:
Standard product coverage on a smooth surface is 100 sq. ft. per one gallon, per coat (est. 10 mil). At least two coats are always recommended. More coats equal longer life. Rough surfaces will require additional product and drying time. Minimum application rate is two gallons per 100 square feet.

Weather & Drying Guidelines:
Ames’® Block & Wall® Liquid Rubber is best applied between 50° to 90° F (10° to 32° C) on warm dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in 2-8 hours, depending on thickness of application and weather. For best results wait a minimum of 24 hours between coats. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.

Clean-up, Storage, and Disposal:
Clean tools and small spills with water. Store unused product in its original container, tightly sealed and protected from freezing. Dispose of this product in accordance with local, state, or federal requirements.

Can be used in Conjunction with:
Block & Wall® Liquid Rubber outperforms isocyanate urethanes, and works well as a waterproofing membrane for Ames® products such as Safe-T-Deck®, Snow Seal®, Maximum-Stretch®, Block & Wall® Acrylic. Topcoat walls with Paint & Prime®.
