Below Grade Exterior Foundations

Application Instructions

Preparation:

Read all label instructions before proceeding. Be sure surfaces are clean and dry before the coating application. Pressure wash when possible using pure water. Be sure surfaces are clean and completely dry before the coating application. Do not use any soaps, or detergents. Remove all loose paint, tar, dirt, oil, and grease leaving surface clean and completely dry. In certain situations a shot-blaster may be needed to help clean and roughen the surface. Always run a test patch first in an inconspicuous area to ensure that proper adhesion and drying occurs and the product works to your satisfaction. All cracks, joints (1/8″ or less), and seams should be caulked with a non-silicone, paintable caulk or Ames® Blue Max® Trowel Grade coating and filler. For larger cracks (1/8″ or larger) fill with a cementitious filler. Make sure surface is as smooth as possible. For best results and adhesion, it is ideal to apply coating over a bare surface void of paint or residue of any kind. Product comes ready to use, no mixing or stirring required. For newly poured concrete, you must allow at least 30 days for complete dry and cure time before applying product.

Tools:

Ames® Blue Max® or Ames®  Block & Wall® Liquid Rubber can be applied with a paint brush, a low nap roller or a commercial/industrial airless sprayer. You may also need Ames® Peel & Stick™ Seam Tape, as well as scissors, a utility knife and a standard paint tray. For larger commercial jobs, we recommend an airless sprayer.

Application:

Steps 1: Directions are the same for both Ames® Blue Max® and Block & Wall® Liquid Rubber.  They do not need a primer.  Caulk all cracks greater than 1/8″ wide with Ames® Blue Max® Trowel Grade.

Step 2: Surfaces with joints, cracks, or where two unlike surfaces come together, require Ames® Peel & Stick™ Seam Tape (PS250, PS450 or PS650) to provide some additional strength and reinforcement. It is important to seam tape all joints and cracks to avoid future cracking and leaking. Prime all surfaces generously with Ames® Blue Max® prior to setting the Seam Tape in place.

Step 3: Apply a liberal topcoat of Ames® Blue Max® or Block & Wall™ Liquid Rubber over the Seam Tape and allow to cure.

Important: Ames® Liquid Rubbers must be protected from the suns UV rays if exposed. Top coat with Ames Paint & Prime® or similiar Ames® Acrylic coatings.

Estimated Coverage:

We recommend three gallons per 100 square feet for water containment.  No need to shake or stir prior to use. 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). Two coats minimum, three to four is superior. More coats equal longer life. Rough surfaces will require additional product and drying time.

Weather & Drying Guidelines:

Both Ames® Blue Max® and Block & Wall® Liquid Rubber are best applied between 50° to 90° F (10° to 32° C) on warm dry surfaces. For exterior applications apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in 30 minutes to 2 hours, depending on thickness of application and weather. It continues to cure for up to 2 weeks. A slight tack is normal after drying. Ames® Blue Max® may be re-coated or top coated when it is dry to the touch. 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: 

Ames® Blue Max® trowel-grade and works well as a primer and waterproofing membrane for Ames® Safe-T-Deck®, Ames® Snow Seal®, Ames® Maximum-Stretch®, Ames® Block & Wall®, Ames® Iron Coat® and many other coatings. Ames® Blue Max® must be top coated for UV protection in exterior applications.
