Maxcrete 622 Self-Leveling Mortar

TECHNICAL SPECIFICATIONS

Below is a detailed technical specification table for Maxcrete 622 Self-Leveling Mortar, tested according to ASTM standards:

APPLICATIONS

Maxcrete 622 Self-Leveling Mortar is commonly used in the following applications:

• Leveling and creating an even concrete floor surface before installing vinyl flooring, epoxy paint, carpeting, ceramic tiles, and wood flooring.

• Repairing and leveling old, uneven floor surfaces.

• Preparing subfloors for interior projects requiring high flatness and aesthetics.

INSTALLATION GUIDE

Step 1 – Surface Preparation:

• Concrete surface must be at least 14 days old, and screed must be 7 days old.

• Clean off oil, grease, dust, and excess cement mortar. Dampen the subfloor and remove any standing water before pouring.

• Erect sturdy formwork, ensuring it is watertight.

Step 2 – Mixing:

• Pour 5 liters of clean water into a bucket, then gradually add 25 kg of Maxcrete 622 powder.

• Use an electric mixer at 500 rpm, keeping the paddle close to the bottom, and mix for 2 minutes until the mixture is smooth, homogeneous, and lump-free.

• If a thickness greater than 5mm is required, clean, dry aggregate of 1-3mm size can be added after mixing the mortar.

Step 3 – Pouring:

• Pour or pump the mortar immediately after mixing. Apply continuously to avoid cold joints.

• Use a spiked roller to roll back and forth to remove air bubbles, resulting in a smoother surface.

• Recommended application thickness: 2–5 mm.

Step 4 – Curing:

• Protect the surface from sun, wind, dust, and rain.

• Light foot traffic is possible after 24 hours. Tile installation after 72 hours, vinyl/carpet/wood flooring installation after 7 days.
