Rubber flooring is very important in quality selection, but it is even more important in the selection of construction personnel. Understanding the construction process of rubber flooring before applying rubber flooring can make you more proactive in choosing construction team personnel.

Here's a detailed introduction to the construction process of Andatei rubber floor:

The quality standard of the foundation floor: hard, flat, dry, clean and free of cracks.

1. Hard: the foundation ground should be cement concrete finely plastered ground, and the compressive strength should be above C25;

2. Leveling: On the cement floor that has been plastered, the average height difference measured with a 4-square-meter ruler is not greater than 2mm; there are no pits with a diameter greater than 10mm and cracks greater than 3mm on the ground;

3. Drying: relative humidity of cement floor ≤7%; site temperature ≥15℃;

4. Clean: there is no cement ash, iron lumps, gypsum mud scars and other construction tools on the ground;

5. No cracks: There are no large or small cracks loose on the surface of the ground foundation.

Floor-detection

⒈ Use a temperature and hygrometer to detect the humidity and humidity. The indoor temperature and the surface temperature should be around 15°C. Construction should not be below 15°C and above 35°C. The relative air temperature suitable for construction should be ≤7%.

⒉ Use a moisture content tester to detect the moisture content of the base layer, and the moisture content of the base layer should be less than 7%.

3. The strength of the base layer should not be lower than the requirement of the strength of cement mortar C25, otherwise suitable self-leveling cement should be used to strengthen the strength.

⒋ Test results with a hardness tester, the surface hardness of the base layer is not less than 25 MPa.

⒌For the construction of rubber floor materials, the unevenness of the base layer should be less than 4 mm in the range of 2 meters of ruler, otherwise suitable self-leveling cement should be used for leveling.

Floor - Pretreatment

1. Use a floor grinder with more than 1000 watts equipped with appropriate grinding discs to polish the floor as a whole to remove paint, glue, paint and other residues, raised and loose plots, and empty plots must also be removed.

⒉ Use an industrial vacuum cleaner of not less than 2000 watts to vacuum and clean the floor. For cracks on the floor, stainless steel reinforcing bars and polyurethane waterproof opening adhesive can be used to lay quartz sand on the surface for repair.

Interface Agent - Primer

⒈Absorptive base layer such as concrete and cement mortar leveling layer should be sealed and primed with multi-purpose interface treatment agent diluted with water at a ratio of 1:1.

⒉ For non-absorbent base layers such as ceramic tiles, terrazzo, marble, etc., it is recommended to use a dense interface treatment agent for primer.

⒊If the moisture content of the base layer is too high (>7%) and needs to be constructed immediately, epoxy interface treatment agent can be used for primer treatment, but the premise is that the moisture content of the base layer should not be greater than 8%.

⒋The construction of the interface treatment agent should be uniform without obvious liquid accumulation. After the surface of the interface treatment agent is air-dried, the next self-leveling construction can be carried out.

Self-leveling construction - mixing

⒈ Pour a bag of self-leveling cement into a mixing bucket filled with clean water according to the specified water-cement ratio, and stir while pouring.

⒉ In order to ensure uniform self-leveling stirring, it is necessary to use a high-power, low-speed electric drill with a special stirrer for stirring.

3. Stir to a uniform slurry without agglomeration, let it stand and mature for about 3 minutes, and then briefly stir once.

⒋The amount of water added should strictly follow the water-cement ratio (please refer to the corresponding self-leveling instructions). Too little water will affect the fluidity, too much will reduce the strength after curing.

Self-leveling construction - laying

1. Pour the stirred self-leveling slurry on the construction floor, it will flow and open the ground by itself. If the design thickness is less than or equal to 4 mm, it needs to be scraped with a special tooth scraper;

2. Then, the construction personnel should put on special spiked shoes, enter the construction ground, and use a special self-leveling air roller to gently roll on the self-leveling surface to release the air mixed in the stirring to avoid bubbles and pits and the height difference of the interface. The site should be closed immediately after completion, walking is prohibited within 5 hours, heavy objects are avoided within 10 hours, and the rubber floor can be laid after 24 hours;

3. In winter construction, the laying of the floor should be carried out 48-72 hours after the self-leveling construction;

4. If the self-leveling needs to be finely ground and polished, it should be carried out 12 hours after the self-leveling construction;

Rubber Flooring - Pre-laid

⒈ Whether it is a coil or a block, it should be placed on site for more than 24 hours to restore the memory of the material and the temperature is consistent with the construction site.

⒉ Use a special trimming knife to cut and clean the burrs of the coil.

3. When the coil is laid, the overlap of the two materials should be overlapped and cut, generally requiring an overlap of 3 cm. Be careful to keep a knife cut. When the blocks are laid, there should be no joints between the two pieces of material.

glue-paste

⒈ According to the different types of rubber floors, you can choose super-strength floor glue, two-component rubber floor glue, and other special floor glue.

⒉ When using two-component rubber floor glue, please note that it must be stirred evenly according to the specified ratio.

⒊ Coiled material: Please roll up the coiled material separator, use a vacuum cleaner to clean the ground and the back of the floor, and then use a suitable scraper to scrape the glue.

⒋Block material: Turn the block material from the middle to both sides, and also clean the ground and floor and scrape the glue.

⒌The super-strength floor glue should wait about 10-20 minutes after scraping the glue. The two-component rubber floor glue can be pasted after squeegeeing.

Rubber Flooring - Exhaust, Rolling

⒈ After the floor is pasted, first use a cork block to push it flat and squeeze out the air, and then use 50 kg of steel to roll the surface. The two-component adhesive should be rolled again after 2 hours, and the warped edge of the splicing should be repaired in time. .

⒉ Please wipe the excess glue on the floor surface evenly in time.

⒊Welding must be carried out 24 hours after the floor is laid.

Rubber Flooring - Cleaning, Maintenance

⒈ "Andatai" brand series floors are developed and designed for indoor venues, and should not be laid and used in outdoor venues.

⒉ Please select the corresponding cleaning agent for regular cleaning and maintenance according to the method recommended by the manufacturer.

3. High-concentration solvents such as toluene, banana water, strong acids, and strong alkali solutions should be avoided on the floor surface, and inappropriate tools and sharp scrapers should be avoided or damage the floor surface.
