2. For better adhesion, surfaces should be dry, frost-free, and
fully cured a minimum of 28 days.
Note: It is the responsibility of the installer/applicator to ensure
the suitability of the product for its intended use.
Application
1. Use cartridge in standard caulking gun. Trim cartridge tip to
desired bead size. Puncture seal multiple times with a seal
punch.
2. Use in joints of maximum width of 1½ in. and depth of 1 in. If
the gap is more than 1 in. deep partially fill with a closed-cell
backer rod or clean, dry sand before filling with product. The
maximum finished depth of Akonaflex Pro Expansion Joint
Filler should be ½ the thickness of the width of the joint (2:1
width-to-depth ratio).
3. Repair can be tooled to even out the surface. Taping on each
side of a crack can give finished joints a cleaner appearance.
4. For best results, air and surface temperature should be
between 40°F-100°F (4°C-38°C) for proper application. Do
not apply if rain threatens or is predicted within 2 hours.
Curing
Product should be air-cured. Protect from traffic and debris for
24 hours. Allow joint filler to cure for at least 2 hours
before exposing to water; reaches full cure in 24 hours. (Lower
temperatures and humidity can extend cure time.) If painting is
desired use a water-based paint, allow a minimum cure time of
24 hours prior to painting.
Clean Up
Tools should be cleaned with a citrus or solvent-based cleaner
before the product cures. Excess material may be cleaned with
a damp cloth and/or mineral spirits. Avoid getting sealant on
skin. Wash hands with soap and water. Excess cured caulk can
be removed with a razor blade. Avoid undercutting the seal.
Limitations
• Follow all industry standard safety procedures when handling,
such as gloves and eye protection.
• Use opened cartridge the same day.
• Rigid paints/coatings (including epoxy coatings) over flexible
sealants may result in a loss of adhesion of the paint/coating
due to potential movement of the sealant.

3. PRODUCT DESCRIPTION
Akonaflex Pro Expansion Joint Filler is a superior-grade, one-
component, urethane sealant and filler to be used in concrete
joints as well as a wide variety of substrates. Its semi-self-
leveling characteristics provide a smooth finish which makes it
ideal for filling cracks or gaps on horizontal surfaces such as
concrete driveways, sidewalks, patios, steps, garage floors,
above ground foundations, and other concrete surfaces. Fills
expansion joints up to 1½ in. wide x 1 in. deep, and contains a
unique, specially-formulated technology which allows it to be
exposed to water after only 2 hours without washing out.
Reaches full cure after 24 hours. Won’t crack or shrink and
acts as an excellent waterproof seal.
