Floorings

Industrial Floorings                            Sports Court Coating

 

Traditional flooring in the form of concrete or asphalt that in the past have been the most commonly used may not, in many cases, now satisfy the demands that have been placed on it. Bitumen floorings have poor solvent resistance while concrete floorings are easily attacked by chemicals and oils and have low abrasion, wear, and impact resistance.

Floor coatings are widely used to overcome all the problems that are mentioned previously and also to make the surface easily cleanable and enable it to maintain high degree of hygienety.

Azmeh Company provides coatings for the floor covering of two main classes of floorings:

I- Industrial concrete floor coatings are available in three types:

1.      Epoxy floor coating (for low mechanical loads and good water, chemical, and abrasion resistance) EPX16.

2.      Epoxy floor coating (for medium mechanical loads, good chemical resistance, acceptable gloss, and fast application) EPX26.

3.      Self levelling floor coating (for high mechanical loads, wear resistance, very good flexibility, and good water and chemical resistance) EPX06.

 

II- Sport Court Coating for bituminous and concrete substrates.

I- INDUSTRIAL FLOORINGS

The technical requirements that makes industrial floor coatings inevitable are:

1-Preservation of concrete surfaces from abrasion which prevent dusting of concrete floors.

2-Resistance to water especially in permanent wet areas.

3-Resistance to chemicals.

4-Providing an easy to clean substrates and maintaining a high degree of hygienity.

5-Preventing bacterial growth.

6-The need of various colours to provide pleasant working conditions and distinctive floor finish areas.

7-Slip resistance.

 

Different factors are to be considered for a successful protection of an industrial floor such as the right selection of the most suitable material, a proper surface preparation, and installation by a competent applicator.

 

A- EPOXY FLOOR COATING (for low mechanical loads):

Epoxy floors coated by EPX16 (two component epoxy coating) are used in areas where chemical and abrasion resistance are required. EPX16 is applied over primed substrates in relatively thin layers (up to 500 microns). Typical uses are in textile industries, chemical plants, stores and warehouses, workshops, garages and in light industrial plants.

B-SELF LEVELING EPOXY FLOOR COATING (for medium mechanical loads):

Epoxy floor coating (EPX26) is a good flow floor finishing coat, used in areas not exposed to high mechanical abrasion.  EPX26 should be applied over primed substrates in relatively thin layers (up to 1mm) to provide high chemical resistance, good durability under foot traffic and light industrial trucking, and an aesthetic appearance to floor surfaces.

Typical uses are in hospitals, laboratories, food and pharmaceutical industries, clean rooms, stores, shops, schools, industrial kitchens, canteens, showrooms, garages, and in all industries that require moderate traffic on plant floor.

C-EPOXY FLOOR COATING (For high mechanical loads):

Epoxy floor coating (EPX06) is a self leveling free flowing coating recommended for areas subjected to heavy wear. EPX06 should be applied over primed substrates to a thickness of approximately 2 to 4mm and is considered as heavy-duty floor covering providing a tough, skid, wear, and chemical resistant floor covering. In addition to the aesthetic appearance that provides to floor surfaces.

Typical uses are in abattoirs, breweries, pharmaceutical, dairies, food and soft drink factories, cold rooms and stores, chemical plants, battery rooms, oil refineries, and in all industries that require heavy traffic on plant floor.

II- SPORTS COURT COATING

Sport Court Coating “WT14” based on acrylic latex (Water base acrylic emulsion) is recommended for exterior or interior tennis court, Basketball, handball, volleyball and other sport courts and also for children playground, terraces, patios and walkways. WT14 has been especially formulated to create a skid resistant surface. It will help to weatherproof, protect and preserve the original surface and making it more attractive and provide a long lasting color in all climatic conditions. In addition, WT14 is an easy to apply economical floor coating providing exceptionally tough, flexible and durable finish.

Note:

WT14 is not recommended for use on a surface on which heavy vehicles may be parked.

Once applied, the court coat (WT14) does not normally require any particular attention. Cleaning can occur with low-pressure water with mild detergent solution. In case of the presence of any damaged area, the floor can be easily touched up by applying one or two coats of WT14 to the damaged area, after proper cleaning and preparation. If a renewal coat would be desired, a new coat of WT14 can be applied directly over cleaned and dry original coat.

 

SUBSTRATE TREATMENT

The right selection of suitable material for industrial or court coating does not ensure alone successful coating on the floor. A proper surface preparation of concrete surfaces and installation by a competent applicator should be performed to ensure long term bond between the concrete and the coating. Coating may fail to stick on the surface for many reasons such as dirt or dust is not removed during surface preparation, the surface is not dry or too smooth, salts are present on the surface of concrete, and finally the top layer of the concrete surface is weak.

 

For these reasons the surface preparation procedure required is as follow:

NEW CONCRETE New concrete must be cured at least 28 days at 21ºC with a relative humidity (RH) of 50%, or equivalent time. Laitance, the fine cement powder that come to the surface when concrete is laid, should be removed by mechanical means.
OLD CONCRETE Cleaning should be carried out by mechanical means using grinding or vacuum assisted shot blasting machine or by other mechanical means (sand blasing). Then all dust and loose debris should be removed using compressed air machine.

Other method of cleaning can also be used. Steam cleaning with detergent solution is best to remove oil and grease. Scrubbing with hot caustic solutions can also be used to remove mineral oils and greases. It is, however, necessary to wait for the concrete to dry out before coating.

Concrete contaminated by animal fats should best be removed by sand blasting or flame blasting.

A number of tests should be carried out over concrete surfaces prior to floor coating. The moisture content of concrete should be less than 5%. The tensile strength of the concrete surface should be not less than 1.0 MPa and the minimum compressive strength should be 3 MPa.

 

After cleaning of new or old concrete substrate, fill all cracks, holes, voids, and surface damage using STOP200  prior to priming. The following tables show the different stages to be followed when applying industrial flooring (Table 1) or Court coating (Table 2):
