Concrete Surfaces Where Polyurea Application Will Be Made

The concrete class of the surface where Polyurea application will be made, should have sufficient hardness feature.

The surface should be smoothly glazed with the tray fitted on the glazing machine, an even and waveless surface should be obtained. The joint cutting process should be made in accordance with the general engineering principals. The relative humidity ratio of concrete should be equal to and below 4% to do the Polyurea coating.   

 

In order to make Polyurea application, it is preferred that the concrete of field
should have the technical specifications mentioned above. The surface of concrete, of which the floor preparation has been completely finished by us, should be robust, crack free, dry and have particles, dust etc. free. The surfaces should not include surface defects such as the pits, the cracks, the segregation and give off a cloud of dust. The surfaces that Polyurea was applied on, are guaranteed and robust.

 

Temperature and Humidity

In order to make a Polyurea application, the ambient and concrete temperature

should be between +5°C and +50°C. The humidity ratio of concrete should be unconditionally, equal to and below %4, conditionally, equal to and below %9,
the relative humidity ratio of ambient below %76 at  23°C. The relative humidity;

should be below the condensation temperature. The humidity ratio of concrete should be measured by using a hygrometer, if necessary, the ambient temperature should be increased. 

 

On the concrete surfaces suitable for making the industrial floor coating; the surface preparation is made in order to remove the low resistance grout layer of the loose particles and roughen the surface. The surface preparation should be made by shot blasting machine (Blastrac).

Usually, marble slimming machines and diamond tipped hand machines and rotatiger are used in the market. Marble slimming machine and diamond tipped hand machines do “slimming” in the micron range. Roughening is out of the question. The rotatiger is used to do roughening, but can not do the real roughening, only leaves the tatches on the floor in patches. Unfortunately, a surface preparation can not be performed as required via the usual methods. The surface preparation is the half of industrial floor coating work. Making an incorrectly surface prepared application similar to a construction with a non solid foundation is not wrong at all.

One of the most important advantages of the shot blast machine; is both to remove the grout layer by roughening and to make the surface oil and dirt free and ready for the liner process.

Every kind of dirt such as dust, paint, oil, grease, which will reduce or hinder
the adherence, should be cleaned off from the surface. If there are layers where the oil has deepened through, these layers may need to be removed. The polyurea can not be applied to the oily surface. The surfaces are made robust, clean and rough.

Mask51 application will be made to the prepared surfaces at the next stage. Mask51 is a bonding layer between polyurea and the surface on which the polyruea to be applied.  In order for the liner to work properly, adhere to the concrete, it is crucial that the surface preparation should be made in accordance with its specification. Therefore, we say, “the surface preparation is the half of industrial coating work”.

Application Definition:

The cleaned, crack and the joint repaired concrete surface without any humidity and water concerns, is made suitable for coating Mask51. The Mask51 liner is applied to the surface. After the Mask51 is impregnated on the surface as a single layer by a roller, the silica and the quartz is spilled upon the Mask51 impregnated surface. Mask51; fills up the spaces, increases the impact and the chemical resistant of surface, at the same time makes the following layers adhere to the surface. After the surface and joint repair is completed, The Mask 51 liner application is made.
