1- Preparation of substrate :

• The surface must be solid, dry and clean from various foreign materials such as dust, dirt, oils and paint.
• The surface must be free of excesses and residues, which can be removed using sharp tools or a hammer.
• If the concrete iron is damaged, it must be ensured that it is completely exposed, then cleaned completely, and it is preferable to use AKRE FLEX 2060 as a foundation layer before use.

2- Application

• Mixing :

Add AKRE REPAIR 720 slowly to the amount of clean water in the mixing bowl (17-19 % water ratio) while avoiding adding any other substances during mixing, then mix using a low-speed mechanical mixer, quietly and for 2 minutes until we reach a homogeneous mixture, free of clusters, let the mixture rest for 2 minutes, then re-mix for (30-60 sec ), and the mixture is ready to apply.

• Spreading :

spread the mixture with a trowel or rubber gloves to stick the materials in place. With a thickness ranging from (5-50 mm) for each layer on several layers for vertical or horizontal surfaces.

When several layers are required, the previous layer should be criss-crossed and at the beginning of its drying before applying the second layer.
The mixture must be used within a period not exceeding 60 minutes after the end of mixing to obtain an effective result.
The consumption is ( ~ 1.9 - 2 kg / m² / mm ), and this ratio changes depending on the surface properties and climatic conditions.

Post-application recommendation :

• Do not apply in very hot weather or when there are strong winds, heavy dust or heavy rain.
• Water absorbent surfaces should be coated with Akre Primer 2054 before application.
• In case of application at high temperatures, the surface should be slightly moistened before application.
• The appropriate temperature when applying (5 - 35 degrees Celsius).
• Dispose of the remaining product after application when exceeding the duration of use.

Cleaning :

• Clean equipment and hands with direct water
• Clean the surface of the stuck material after installation with a wet cloth.
