Roll construction steps
Step 1- Floor detection
Using temperature and humidity agents to detect temperature and humidity, it is advisable to set the indoor temperature and surface temperature at 15 ℃. Construction should not be carried out below 10 ℃ or above 30 ℃. The relative air humidity for easy construction should be between 20% -75%.
Use a moisture tester to test 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 C20. Otherwise, suitable self leveling should be adopted to strengthen the strength.
The height difference of a 2m guiding ruler shall not exceed 4mm
The test result using a hardness tester should be that the surface hardness of the base layer is not less than 1.2 megapascals.
Possible symptoms at the grassroots level:
Pore cracks, humidity, dirt loosening, and lack of adhesion
Step 2- Floor Preparation
Use a ground polishing machine with appropriate grinding discs to polish the floor as a whole, and manually treat local areas.
Step 3- Self leveling construction - Primer
Absorbent base layers such as concrete, cement mortar, and leveling layers should first be diluted with a multi-purpose interface treatment agent in a 1:1 ratio before sealing and bottoming.
For non absorbent substrates such as ceramic tiles, terrazzo, marble, etc., it is recommended to use a dense interface treatment agent for bottoming.
Step 4- Self leveling construction - Mixing
Pour a pack of self leveling materials into a mixing bucket filled with clean water according to the specified water to cement ratio, and mix while pouring.
To ensure even self leveling and stirring, it is necessary to use a high-power, low-speed electric drill with a dedicated mixer for stirring.
Step 5- Self leveling construction - laying
1. Pour the mixed self leveling slurry onto the construction floor and use a specialized toothed scraper to scrape it slightly. Then, the construction personnel should wear specialized nail shoes and enter the construction floor, using the specialized self leveling to release air.
2. The drum gently rolls on the self leveling surface to release the air mixed in during stirring, avoiding bubbles, rough surfaces, and interface height differences.
3. After the construction is completed, please immediately close the site, prohibit walking for 5 hours, avoid heavy objects from hitting within 10 hours, and lay the floor after 24 hours.
4. During winter construction, the laying of flooring should be carried out 48 hours after self leveling construction.
5. After 12 to 24 hours of self leveling construction, perform precision grinding and polishing on the self leveling surface.
Step 6- Floor paving - Pre laying and cutting
Pre cut the required rolls according to the on-site size
Pre lay according to the on-site situation and cut the floor according to the on-site size< br /> If making a call or going up the wall, the wave and wall sections should be paved first, and then the flat sections should be made< br /> Due to the special circumstances on site, it is necessary to first pave the equipment site area. Therefore, the order of pile overturning should be carried out
Pave the required site for the equipment first, and then proceed with the paving and wall installation.
Step 7- Floor paving - Pasting
1. When laying the roll, fold one end of the roll up. First, clean the floor and the back of the roll, and then scrape the glue onto the floor. Different adhesives may have different requirements during construction, please refer to the corresponding product manual for specific construction.
2. The adhesive construction uses imported environmentally friendly water-soluble adhesive. After about 10 minutes of application, gently touch the adhesive with your fingers. When you feel the viscosity but do not touch your hands, it is a good time to lay carpets.
Step 8- Floor paving - Exhaust and rolling
1. After pasting the flooring, first use cork to push and flatten the surface of the floor and squeeze out air. Subsequently, use a 50 or 75 kg steel roller to evenly roll the floor and promptly repair the warped edges at the joints.
2. Any excess glue on the surface of the floor should be wiped off in a timely manner.
3. After 24 hours, proceed with slotting and welding.
Step 9- Floor paving - Splitting
Slotting must be carried out after the adhesive has completely solidified. Use a dedicated slotting tool to groove along the seam. To ensure secure welding, the seam should not be penetrated. It is recommended to groove at a depth of 2/3 of the floor thickness.
At the end where the seam opener cannot cut, please use a manual seam opener to sew at the same depth and width.
Before welding, residual dust and debris inside the groove must be removed.
Step 10- Floor paving - Welding seam
Manual welding or automatic welding equipment can be used for welding first.
The temperature of the welding gun should be set at around 350 degrees. At an appropriate welding speed (to ensure the melting of the welding rod), press the welding rod evenly into the prepared groove.
When the welding rod is semi cooled, use a welding rod leveler to roughly cut off the part of the welding rod that is higher than the floor level.
After the welding rod is completely cooled, use a welding rod leveler to cut off the remaining protrusions of the welding rod.
