Spc floor installation

1. Floor inspection

 

1. Use a temperature and hygrometer to detect the temperature and humidity. The indoor temperature and the surface temperature are preferably 15°C, and construction should not be below 5°C and above 30°C. The relative air humidity suitable for construction should be between 20% and 75%.

 

2. 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%.

 

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.

 

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

 

5. For the construction of stone-plastic 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.

 

2. Floor pretreatment

 

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

 

2. Vacuum and clean the floor with an industrial vacuum cleaner of not less than 2000 watts.

 

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

 

3. Self-leveling construction - primer

 

1. 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 interface treatment agent.

 

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

 

3. 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 of the base layer should not be greater than 8%.

 

4. The construction of the interface treatment agent should be uniform, and there should be no obvious liquid accumulation. After the surface of the interface treatment agent is air-dried, the next self-leveling construction can be carried out.

 

Fourth, self-leveling construction - mixing

 

1. 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.

 

2. In order to ensure even self-leveling stirring, a high-power, low-speed electric drill with a special stirrer must be used for stirring.

 

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

 

4. 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 fluidity. Too much will reduce the strength after curing.

 

5. Self-leveling construction - laying

 

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

 

2. Then, the construction personnel should wear 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 pits and the height difference of the interface.

 

3. Please close the site immediately after the construction is completed, prohibit walking within 5 hours, avoid heavy object impact within 10 hours, and lay the stone-plastic floor after 24 hours.

 

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

 

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

 

6. Floor paving - pre-laying and cutting

 

1. The floor should be placed on site for more than 24 hours, so that the memory of the material can be restored, and the temperature is consistent with the construction site.

 

2. When the blocks are laid, the two materials should be close to each other and there should be no joints.aqua stone spc flooring 

 

Seven, floor paving - paste

 

1. Select the appropriate glue and scraper for the stone-plastic floor.

 

2. When paving the tiles, please turn the tiles from the middle to both sides, and also clean the ground and the back of the floor and glue them.

 

3. Different adhesives have different requirements during construction. For details, please refer to the corresponding product manual for construction.

 

3. The excess glue on the floor surface should be wiped off in time.

 

Eight, floor cleaning and maintenance

 

1. The stone-plastic floor is developed and designed for indoor places, and should not be laid and used in outdoor places.spc stone plastic composite flooring

 

2. 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.
