MegaTamir K Yapısal<br />
Cement Based Structural Repair Mortar With Thick Filling<br />
PRODUCT DESCRIPTION<br />
Cement based structural repair mortar with polymer and fiber additive and with thick<br />
aggregate, which is resistant to temperature changes.<br />
AREAS OF USE<br />
MegaTamir K Yapısal is used along with MegaFilm AK in indoors and outdoors spaces,<br />
especially on underground, ground and underwater floors of all buildings, which are required<br />
to be sulfate and chlorine resistant, for waterproofing and beveling prior to final coating, for<br />
repair, for surface smoothing, and for the repair of the concrete and appurtenances, which<br />
may have been damaged due to abrasion by iron reinforcements.<br />
MegaTamir K Yapısal yields excellent results particularly in the case of beveling applications<br />
and the filling of rod clearances and drilling core gaps.<br />
PRODUCT ADVANTAGES<br />
• Yields effective results in structural repair applications thanks to high compressions strength.<br />
• Fit for use for the structural repair of any reinforced concrete <strong>construction</strong> elements.<br />
• Poses very high bonding capability.<br />
• Enables a lasting and smooth surface following the application.<br />
• Does not contain sulfate and chloride ions.<br />
• Resistant to water and frost.<br />
• Prepared and applied easily.<br />

APPLICATION PROCEDURE<br />
Application Surfaces<br />
Indoors and Outdoors Floors;<br />
- Cement based trowel coating<br />
- Concrete (MegaFilm or MegaFilm BB primer applied)<br />
Indoors and Outdoors Walls;<br />
- Cement based plaster (MegaFilm primer applied)<br />
- Concrete (MegaFilm or MegaFilm BB primer applied)<br />
Ceilings;<br />
- Cement based plaster<br />
- Concrete (MegaFilm or MegaFilm BB primer applied)<br />
Surface Preparation<br />
Concrete Surfaces;<br />
• The application surfaces should be dry, clean, sound and dust free, and should have been<br />
cleansed of oil, dirt or any materials that may prevent adhesion, and any such materials as<br />
mortar and cement residues should be scraped from the application surface.<br />
• Upon the completion of the surface cleaning, MegaFilm primer should be applied in a<br />
single coat with a brush and be left to dry for 1 to 2 hours in order to enhance the bonding<br />
strength and stabilize the surface absorption.<br />
• Exposed concrete surfaces should be applied MegaFilm BB exposed concrete primer in<br />
single coat and be left to dry for minimum 3 hours prior to the application of the adhesive<br />
mortar in order to enhance the adhesion strength.<br />
Iron Reinforcements;<br />
• Any rust on iron reinforcements, if applicable, should be cleaned.<br />
• Two coats of MegaFilm AK should be applied with a brush on the iron reinforcement, and<br />
MegaTamir K Yapısal should be applied subsequently before the primer dries.<br />
Application Methods<br />
• MegaTamir K Yapısal should be applied in equal thickness on all surfaces to be repaired<br />
or smoothed.<br />
• The surface should be finished with a moist sponge or a smoothing trowel following the<br />
application.<br />
Application Recommendations<br />
• The product should, once mixed, be used before the expiration of its pot life. Any product,<br />
the pot life of which has expired, should not be used during the application.<br />
• Any such foreign substance as lime, cement or plaster should not be added to the mortar<br />
prepared.<br />
• Any extra water should not be added to the mixture.<br />
• The product should not be applied on unsound surfaces. The soundness and the load<br />
bearing capacity of old surfaces should be checked prior to adhesion.<br />
• The surface should be preserved from air currents and water contact during and after the<br />
application.<br />
• The product should not be applied to such surfaces, which are exposed to risk of freezing<br />
within the next 24 hours, which are frozen or the frost of which is thawing.<br />
• Due care should be taken to ensure that the material is not exposed to direct sunlight in hot<br />
weather conditions, and the product should be mixed with cold water.<br />
• The product should not be applied on extremely windy weather conditions or on hot<br />
surfaces, which are exposed to direct sunlight; and in the cases, where application is<br />
imperative under such conditions, the environment and the surface should be prepared for<br />
application in advance.<br />
• The product should not be applied in rainy weather conditions, and the application surface<br />
should be preserved from rain for a period of 24 hours.<br />
• Refer to our technical support hotline for recommendation on different surface applications.<br />
