Hard mortar (hard industrial concrete)

Hard mortar (hard industrial concrete)

Properties and effects:


Ability to stick to fresh concrete Compressive strength of about 1000 kg/cm2 and higher resistance to acids and bases than concrete Applicable on all concrete surfaces High resistance to freeze and thaw cycles No dust generation and ease of implementation High resistance to mechanical loads Very high wear resistance Reduction of execution time compared to other floor coverings






It is a layer of industrial concrete with a thickness between 1 and 2 cm. This floor covering is based on soft cement materials and chemical compounds with higher compressive strength and impact resistance, which is dry sprayed on fresh concrete and is completely consistent with concrete, and it is applied to the dry sprayed parts after treatment (screws and trowels). Drawing) is completely smooth, integrated, hard and resistant to wear. The life of flooring is 20 years. This minimum life of flooring is almost constant for all places, even in places with heavy traffic and heavy machinery. Amount of consumption: depending on the conditions and surface usage, about 3 to 7 kg of hard mortar is needed to cover one square meter.



The above product can be stored for 12 months in the original packaging and away from moisture and sunlight.



Physical and chemical state:


packaging method:

It is supplied in 20 kg bags.




In environments where the temperature reaches above 50 degrees Celsius or there is flammability, hard mortar flooring must be used instead of epoxy or any other flooring. It is better to use hard mortar in environments with long distances. Compared to epoxy, it is more economical and its execution time is faster. It can be used in places that are under pressure, as well as the floors of manufacturing and industrial factories, warehouse floors, cold floors of houses, parking lots, airports, ports and terminals, educational and military centers, power plants and printing houses.


Method of Use:

Hard mortars are done in two ways: spraying and mortaring, which is used for places with low traffic and is a surface hardener. Depending on the desired surface use, sprinkle the powder on the concrete sections to absorb the moisture of the concrete. Achieving a smooth and uniform surface by using an electric (butterfly) trowel, pay the surface level. Use the trowel when there is a slight indentation when you walk on it, and after finishing troweling, start treating the hardened concrete by spraying water. Note: The temperature of the floor covering is between 5 and 35 degrees, and these conditions must be constant for 2 days after the application of hard mortar. Shrinkage joints must be 5 cm lower than the finished surface of the hard mortar, and the depth of the joints must be 5 cm and wide. It should be 1 to 1.5 cm, and before applying hard mortar, it is better to apply 10 cm of fresh concrete and then apply floor covering. You cannot replace this flooring with fresh concrete, but you can reduce the thickness of fresh concrete and use hard mortar. Due to the expansion joints, which is one of the requirements of hard mortar flooring, this flooring is not the same as epoxy flooring. It should be noted that these joints are made with a cutter and these joints depend on the distance between the concrete slabs and it is between 24 and 30 times the thickness of the concrete and the maximum distance between the joints is 5 meters. It is not recommended to use antifreeze for flooring because it reduces the strength of the flooring. brings down Washing should be done once every 6 months (use water and normal cleaning materials, do not use acid). You can use anti-shrinkage concrete additive to prevent cracking. If the concrete under the work is old, be sure to use new concrete. and glue should not be used. Fresh concrete means concrete that has passed 12 hours since concreting
