Characteristics
Block & Wall™ Liquid Rubber is a blend of adhesive, high strength,
elastomeric, liquid rubber designed for waterproofing basement
walls and below grade foundations. With up to 1800% elongation,
Block & Wall™ Liquid Rubber adheres to concrete, galvanized steel,
aluminum, and plywood. Block & Wall™ Liquid Rubber dries to a
tough elastic membrane that resists cracking and peeling.

Surface Preparation
All surfaces must be sound and free of spalled areas, loose nails, screws, sharp
protrusions, frost, dirt, grease, oil, or other matter that will hinder the
adhesion of the membrane installation. Clean loose dust and dirt from the
surface by brushing or wiping with a clean, dry cloth, brush, or broom.
Pressure wash if appropriate for the job conditions.
Concrete
Should be cured in place 28 days minimum. All surfaces need to be smooth,
with sharp protrusions such as cold joints ground flush. Honeycomb, holes,
cracks, and joints exceeding 1/8”and up to 5/8” across shall be filled with Blue
Max® Trowel or Blue Max® Caulk.
Concrete Masonry Unit (CMU)
Mortar joints shall be struck flush and free of voids exceeding 1/8” across.
Mortar droppings shall be removed from brick ties and all other surfaces
accepting Block & Wall™ Liquid Rubber Membrane and accessories. Allow
mortar joints to dry a minimum of 28 days prior to application of the Block &
Wall™ Liquid Rubber and accessories.
OSB, Plywood, Lumber, Pressure-Treated Wood
Wood and wood sheathing need to be flush at joints with gaps between
boards according to building codes and manufacturer requirements.
Moisture content, measured with a wood moisture meter in the core of the
substrate, requirement is below 20%. Do not cover any wooden materials
with Block & Wall™ Liquid Rubber and/or accessories if moisture content is
20% or above.
Application Methods
Apply between 50° - 90° F on a warm dry surface. Surface temperature must
be 5° F higher than the dew point and rising

Application Instructions
Review product Application Guide before proceeding. Contact Ames
Research Laboratories Technical Service Representatives
for questions
pertaining to the coating system application and required coating film
thickness. Conduct a test patch to ensure proper adhesion.
• Block & Wall™ Liquid Rubber must be top coated with a high-quality
acrylic paint for all exterior exposures. On interior surfaces Block & Wall™
Rubber must be top coated with a high-quality acrylic paint for washability
• Do not apply Block & Wall™ Liquid Rubber if the temperature is expected
to drop below 32° F within 24 hours of application.
• Do not apply in high heat areas of 180° F
• Do not apply over wet substrates
