Quartz-Based Surface Hardener Mortar


The product is a cement-based, ready for use surface hardening material containing quartz aggregates of a special particle size and chemical additives enhancing product performance, which is applied through spreading in the form of powder on freshly finished floor concrete that would experience medium to heavy loads.

It conforms to TS EN 1504 – 2 / April 2008 standard.

It can be used safely on the floors of industrial plants, garages and parking lots, hangars and mechanical workshops, fuel stations, warehouses, and interior and exterior spaces. It is applied on fresh concrete surfaces where a high degree of mechanical resistance is required, and where dusting is not desired to happen on concrete surface.


It is easy to apply on freshly finished floor concrete. Thanks to its content of special chemical additives, it absorbs the water content of the floor concrete on which it is applied, and establishes a single structure with concrete after completion of finishing process. It is 2-4 times more resistant to abrasion than normal concrete surface. It has high adhesion ability. It is resistant to frost-thaw cycle.


The application of the surface hardener  is intended to increase the abrasion, dusting, and impact strengths of concrete and screed on the upper part of concrete, and has no effect on the pressure, tensile, and bending strengths of concrete. Any incorrect projection defects as well as application cracks that may occur in the screed concrete would  be entirely reflected on the surface hardener. A vibrojig should be used to correct the concrete surface to which the surface hardener is to be applied. The floating and monolithic screed applications should be selected based on project requirements. The jigs are placed according to the project. Cement grout should be removed from the concrete surface. The concrete surface is checked before spreading the material. The spreading application should be carried out after completion of the hardening process so that a footprint with a depth of 0.5 - 1.5 cm is left when concrete is pressed depending upon ambient and weather conditions. EKOKAT SURFACE QZ surface hardener must not be spread from far distances when applied in order to prevent the aggregates contained in the surface hardener from dissolving. The product should be sprayed and smoothed as homogeneously as possible. First, 2/3 of the total consumption amount is spread on the concrete surface and spread by machine. The spread material should be allowed to get dampened by absorbing water out of concrete, and the surface hardeners should be integrated to the concrete through the application of a disk finishing process. Then the remaining material should be spread on the concrete surface as in the first application and the same works should be repeated. A fine finishing process should be applied after completion of the rough finishing process. The fine finishing is the one that is performed with a knife. The finishing process with a knife should be done until the desired Brightness is achieved. After the application  of the surface hardener is completed, the surface is cured so as to prevent shrinkage cracks and to provide a dust-free medium. The curing process should be done certainly in the summer and winter. After the application is completed, the joints of the jigs should be cut with a width of at least 4 mm in order to form joints. Joints should be filled with a suitable mastic. The concrete to which EKOKAT SURFACE QZ is to be applied should have a class of at least C25 (350 doses) with a minimum thickness of 15 cm.


Properties such as water and cement in concrete can cause slight color differences. Care must be paid to the timing at the time of application, and correct finishing methods should be used. At the time of application, the effects of wind and sun should be taken into consideration at exterior spaces, and the ambient temperature should be between +5 ° C and +35 ° C. Application should not be performed under very humid and hot weather conditions. It is normal to observe color differences through the drying process. Concrete is recommended to have no additives except under special conditions.
