1- Preparation of substrate :

• The surface must be solid and free of residue of all kinds (cement, coating, oil materials, dust.. etc.) It must be completely dry.

2- Application

• Mixing :

Add AKRE REPAIR 720 slowly to the amount of clean water in the mixing bowl (20 % 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 mortar using a flat trowel with firm pressure to get good adhesion and to ensure that the mortar is stable in its appropriate place, as it is possible to spread the mortar with horizontal or vertical layers. When needed to apply more than one layer you should leave the first layer to dry and become solid before applying the second layer thus that the thickness is between 1-5 mm per layer. The mortar must be used within 60 minutes after mixing to obtain an effective result. The consumption is ( ~ 2 kg / m² / mm ) on average, and this ratio changes depending on the surface properties and climatic conditions.

Post-application recommendation:

• If the application is on a surface exposed to direct sunlight or wind, it is preferable to moisturize the place of application within 24 hours following the application.
• Dispose of the remaining product after application when exceeding the duration of use.
• According to the nature of the surface the mortar must be protected after application using suitable protection chips or cover the treated surface with a durable plastic cover - It is necessary to protect the treated place from winds and direct sunlight to avoid rapid drying.
• The surface becomes ready for use (tiling or painting.... etc.) 24 hours after the end of the application.

Cleaning: :

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

Storage:

• Storage in relatively dry warehouses away from humidity and direct sunlight.
• No more than 10 bags should be placed on top of each other during storage.
• Shelf life 12 months in appropriate conditions.

Packaging:
