Megaİzo Lastik 7
Polymer Emulsion And Cement Based, Double Component,
Semi Elastic Waterproofing Material
PRODUCT DESCRIPTION
Semi elastic waterproofing material comprised of cement based powder component and
polymer emulsion based liquid component, which can be applied prior to the top coating
material.
AREAS OF USE
Megaİzo Lastik 7 is applied for waterproofing before the top coating material in such wet
spaces as bathrooms, kitchens and balconies, in terraces, and in such wet spaces as
decorative pools and small sized water tanks. It is suitable for use on horizontal and vertical
surfaces of indoors and outdoors spaces.
double coat on the surface. Once the primary coat thoroughly dries, the secondary coat
should be applied as perpendicularly to the primary coat.
• Edge and corner joints should be beveled with MegaTamir İ and MegaTamir K repair
mortars in order for the maintenance of waterproofing.
• In the cases, where beveling is not performed; Megaİzo Bant should be applied to such
inadequately waterproof spots as edge and corner joint spots in order to ensure the
maintenance of insulation.
• Depending on the nature of the application surface; the secondary coat may be applied after
the placement of Megaİzo File on the primary coat. In the cases, where net reinforcement is
necessary; the net shall be laid on the primary coat before it dries.

APPLICATION PROCEDURE
Application Surfaces
Indoors and Outdoors Walls;
- Cement based plaster (MegaFilm primer applied)
- Concrete (MegaFilm or MegaFilm BB primer applied)
Indoors and Outdoors Floors;
- Cement based trowel coating (MegaFilm primer applied)
- Concrete (MegaFilm or MegaFilm BB primer applied)
Surface Preparation
• Application surfaces should be sound, clean, dust-free, and free from molding oils and
other foreign substances. Such materials as mortar and cement residues should be peeled off.
• 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.
• 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.
• 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
• Megaİzo Lastik 7, the mixture of which should have been prepared, should be applied in
Application Recommendations
• Due care must be taken to ensure that the insulation material is not damaged by mechanical
impacts in the cases of coating over the insulation.
• The product should not be applied against negative water pressure.
• 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 foreign material should not be added into the product’s components of the product
during the application.
• 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 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.
