Floor Detection

Floor detection

✦Use a temperature and humidity meter to detect the temperature and humidity. The indoor temperature and the surface temperature are preferably 20℃-30℃. Construction is prohibited when the temperature is lower than 20℃; the relative air humidity suitable for construction should be between 20%-75% .
 

✦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 3%.
 

✦The strength of the base layer should not be lower than the requirement of concrete strength C-20, otherwise suitable self-leveling should be used to strengthen the strength.
 

✦The result of testing with a hardness tester is that the surface hardness of the base layer is not less than 1.2 MPa.
 

✦For the construction of PVC floor materials, the unevenness of the base layer should be less than 2 mm in the range of a 2-meter ruler, otherwise suitable self-leveling should be used for leveling.

Floor pretreatment

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

✦Use an industrial vacuum cleaner of not less than 2000 watts to vacuum and clean the floor. Before paving the floor, there should be no floating dust or debris on the ground.

✦For cracks on the floor, stainless steel reinforcing bars and polyurethane waterproof adhesive can be used to repair the surface with quartz sand.

Self-leveling construction - primer

✦The absorbing base layer such as concrete and cement mortar leveling layer should be sealed and primed after being diluted with water at a ratio of 1:1 with a multi-purpose boundary treatment agent.

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

✦If the moisture content of the base layer is too high (>3%) and it needs to be constructed immediately, epoxy interface treatment agent can be used for primer treatment, but the premise is that the moisture content should not be greater than 8%.
 

✦The 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

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

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

✦Stir until there is a uniform slurry without agglomeration, let it stand and mature for about 3 minutes, and stir once briefly.
 

✦The amount of water added should be strictly in accordance with 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

✦Pour the stirred self-leveling slurry on the construction floor, it will flow and level the ground by itself, and it can be scraped slightly with the help of a special tooth scraper.
 

✦Then, the construction personnel should put on special spiked shoes, enter the construction ground, and use a special self-leveling air release roller to gently roll on the self-leveling surface to release the air mixed in the stirring to avoid air bubbles and pitted surfaces and the height difference of the interface.
 

✦After the construction is completed, please close the site immediately, prohibit walking within 5 hours, avoid the impact of heavy objects within 10 hours, and lay the PVC floor within 24 hours.
 

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

✦If the self-leveling needs to be finely ground and polished, it should be carried out after the self-leveling is dried.
 

Floor cleaning and maintenance

✦The PVC series floor is developed and designed for indoor places, and should not be laid and used in outdoor places.
 

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

✦High concentration solvents such as formaldehyde and banana water, strong acid and strong alkali solutions should be avoided from pouring on the floor surface. The use of inappropriate tools and sharps to scrape or scratch the floor surface should be avoided.
