5. INSTALLATION
Preparation
Read all directions before starting work. Proper surface
preparation is crucial to achieving a successful application.
1. Remove all loose or unsound materials. Thoroughly clean
surface of paint, dirt, dust, grease, or other contaminants
before patching, topping, or placing overlays. Do not apply to
painted, sealed, or waxed surfaces - these contaminants
must be mechanically removed to ensure proper adhesion to
the substrate as chemical removal drives the contamination
into the surface.
2. For patching or filling any holes or cracks, use Akona Repair
Products prior to application of Heavy-Duty Waterproofing
Base Coat and allow curing as recommended for the product.
3. Just prior to application, pre-dampen surface to be
repaired with clean water to saturated surface dry (SSD)
condition with no standing water remaining.

3. PRODUCT DESCRIPTION
Akona Heavy-Duty Waterproofing Base Coat is a Portland
cement-based damp-proofing coating for use over concrete,
block, brick, or stucco surfaces. Use for interior or exterior
coating of foundation, basement, or retaining walls above or
below grade. When applied over non-uniform areas, this
product provides a smooth or textured surface that can be left
as a finished, decorative coating. In addition, this product can
serve as a base coat for paint or similar faux finishes. Please
note that this product needs to be mixed with a mixture of
water and Akona Concrete Bonding Additive (sold
separately, BOM #102659).
