APPLICATION PROCEDURE
Application Surfaces
Indoors and Outdoors;
- Gas concrete
- Brick
Surface Preparation
• The application surface should be dry, clean, sound and dust free, and should have been
cleansed of oil, dirt or any materials that may prevent adhesion, and any such materials as
mortar and cement residues should be scraped from the application surface.
• The surface should be checked and be leveled and smoothed in the event of any defects
prior to masonry with construction elements such as gas concrete and brick.
Application Methods
• The MegaBlok mortar prepared should be spread properly and homogenously in equal
thickness on the application surface with a trowel. The mortar should, then, be dredged with
a 10x10 mm dredge to ensure uniform thickness in application.
• During the masonry, the horizontal and vertical joint gaps should be allowed as 3 mm, and
due care must be taken to ensure that the joint gaps are thoroughly filled with MegaBlok
mortar.
Application Recommendations
• The product should, once mixed, be used before the expiration of its pot life. Any mortar,
the pot life of which has expired, should not be used during the application.
• Any such foreign substance as lime, cement or plaster should not be added to the mortar
prepared.
• Any extra water should not be added to the mixture.
• The product should not be applied on unsound surfaces. The soundness and the load
bearing capacity of old surfaces should be checked prior to adhesion.
• The surface should be preserved from air currents and water contact during and after the
application.
• The product should not be applied to such surfaces, which are exposed to risk of freezing
within the next 24 hours, which are frozen or the frost of which is thawing.
• Due care should be taken to ensure that the material is not exposed to direct sunlight in hot
weather conditions, and the product should be mixed with cold water.
• The product should not be applied on extremely windy weather conditions or on hot
surfaces, which are exposed to direct sunlight; and in the cases, where application is
imperative under such conditions, the environment and the surface should be prepared for
application in advance.
• The product should not be applied in rainy weather conditions, and the application surface
should be preserved from rain for a period of 24 hours.
• Refer to our technical support hotline for recommendation on different surface applications.

APPLICATION INSTRUCTIONS
Mixing Ratio
The product should be mixed with water, weighing equal to 24 - 26 % of the product. (6.0 -
6.5 liters of water for a 25 kg package)
Mixing Equipment
• Low speed electrical mixer (400 cycles/ min.)
• Special tip stirring equipment
Mixing Period
The product should be stirred with a low-speed mixer until any dry dust and globs are
eliminated. The mortar should, then, be stirred once again for 1 to 2 minutes after being had
settled for 2 to 3 minutes following preparation.
Application Equipment
• Steel trowel
Equipment Cleaning
The equipment used should be cleaned with water following the application before the mortar
dries.
