MegaSıva Makine Dıº
Cement Based, Machine Applied Plaster With Enhanced
Adherence For Outdoor Use
PRODUCT DESCRIPTION
Cement based, machine applied plaster for outdoor use with filling material content in
appropriate granulometry, which has been enriched with special chemical for enhanced
workability and strength.
AREAS OF USE
MegaSıva Makine Dıº is used in outdoors spaces on prime coated gas concrete, prime
coated concrete, briquette, brick and natural rock vertical surfaces and ceilings.
PRODUCT ADVANTAGES
• Ensuring high bonding to the surface, the product does not cause spalling and poses high
bonding strength.
• Functions as both roughcast and fine plaster with a single coat application.
• Easily and rapidly applied by machine.

APPLICATION PROCEDURE
Application Surfaces
Outdoors Walls;
- Gas concrete (MegaFilm primer applied)
- Concrete (MegaFilm or MegaFilm BB primer applied)
- Briquette
- Brick
- Vertical surfaces of natural rock
Ceilings;
- 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 1 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 should be preferred.
• The application surfaces should be moisturized with water, where necessary.
• Upon the completion of the surface cleaning, 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 bonding
strength and stabilize the surface absorption.
• Gas concrete surfaces should, prior to the application of the product, be applied MegaFilm
primer and the water absorption of the surfaces should so be reduced.
• 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 application thickness should range between 1.0 cm and 2.5 cm in single coat. In the
cases where the application thickness is to exceed 2.5 cm, an additional coat of maximum 2
cm thickness should be applied upon the sufficient hardening of the primary coat.
• The surface should be gauged and finished after the application.
Application Recommendations
• The surface should be moisturized intermittently for a period 7 days following the application
in order to enhance the endurance of the plaster.
• The product should not be applied to gypsum surfaces.
• The product should, once mixed, be used before the expiration of its pot life. Any product,
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.
