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 />

PERFORMANCE<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 />

(PHONE: 444 4 595)<br />

Surface and Ambient Temperature<br />

The surface and ambient temperature should be between +5°C and +30°C whilst at<br />

application.<br />
