MegaZemin SL20
Self Levelling Grader Trowel Coating (3 - 20 mm)
PRODUCT DESCRIPTION
Cement based, easily spread surface grader trowel coating, which enhances floor strength an
contains special additives.
AREAS OF USE
MegaZemin SL20 is used on such spaces exposed to pedestrian traffic, the cement based
surfaces and concrete slabs in order to form a smooth and contraction free floor with high
surface quality prior to the pavement of flooring materials (such as ceramic, PVC, carpet and
parquet). It is suitable for use on horizontal surfaces of indoors and outdoors spaces.
PRODUCT ADVANTAGES
• Highly adhesion and surface resistant.
• Does not cause cracking and deflection.
• High bending and compressive strengths.
• Enables a smooth surface thanks to its self levelling nature.
• Applied easily and rapidly.
PERFORMANCE
Compressive strength ≥ 35 N/mm 2 TS EN 13892 - 2
Bending strength ≥ 5 N/mm 3 TS EN 13892 - 2
Abrasion resistance ≤ 10 cm 3 TS EN 13892 - 3

APPLICATION PROCEDURE
Application Surfaces
Indoors and Outdoors Floors;
- Cement based floors (MegaFilm primer applied)
- Concrete (MegaFilm or MegaFilm BB primer applied)
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 defects, which are deeper than 2 cm, should be repaired with MegaTamir İ or
MegaTamir K 24 hours in advance. In the cases, where structural repair mortar should be
used; MegaTamir İ Yapısal or MegaTamir K Yapısal may be preferred.
• Upon the completion of the repair process, MegaFilm primer should be applied in a single
coat with a brush and be left to dry for 1 to 2 hours in order to enhance the adherence and
stabilize the surface absorption.
• Exposed concrete surfaces should be applied MegaFilm BB exposed concrete primer in
single coat and be left to dry for minimum 3 hours prior to the application of the adhesive
mortar in order to enhance the adhesion strength.
Application Methods
• The mixture should be poured on the surface, on which MegaFilm or MegaFilm BB primer
has been applied, and be left to spread autogenously. The thickness of the layer should be
adjusted with a plain trowel and depth gauge bead.
• Spiked roller should be employed or spiked shoes should be worn during the application in
order to eliminate any air bubbles within the product and to facilitate the spreading.
• The mixture can spread autogenously within the first 15 to 20 minutes and should,
therefore, be applied to the floor within the said period of time.
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 foreign material should not be added into the product during the application.
• Any extra water should not be added to the mixture.
• 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 given to prevent the exposure of the material to direct sunlight in hot
weather conditions.
• 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 18 - 20 % of the product. (4.5 -
5.0 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 3 to 4 minutes following preparation. The product should be stirred in regular
intervals during the application.
Application Equipment
• Steel trowel
• Depth gauge bead
• Spiked roller
• Spiked shoe
Equipment Cleaning
The equipment used should be cleaned with water following the application before the
product dries.
