Hillary carpet construction process and technical index
Basic ground conditions
1. The ground must be flat, clean, dry, free of cracks, empty, moldy, oil-free, smooth, smooth, smooth, smooth, smooth, and free of seepage, and the water content of the grass is less than 8 %. If the carpet does not meet the above conditions, it is liable to produce bad symptoms such as sticking, sticking edge and opening joints.
2. Human rights PVC woven carpet has high toughness and strong texture. In the treatment of the ground, need to brush a layer of self-flow flat coating, self-flow flat brush requirements uniform can not have a knot. Brush self-leveling will make the carpet and the ground better fit, if not brush the ground, also need to clean the ground without dust attachment.
Pre-paving

2. Site Testing
1. Ground requirements: flat, bright, dry, no sand, no cracks, no seepage, leakage.
It is advisable to use a temperature hygrometer to measure temperature and humidity. The indoor temperature and surface temperature should be 15 ℃
Under 5 ℃ and above 30 ℃ construction, suitable for construction relative air humidity between 20 %-75 %.
3. The moisture content of the base should be less than 3 % by using the water content tester.
The strength of the base should not be lower than the requirement of the concrete strength C-20, otherwise the suitable self-flow level should be adopted
Reinforcing intensity.
5. The test result of using hardness tester shall be the surface hardness of the base not less than 1.2 MPa.
6. For the construction of silari woven carpet products, the flatness of the base should be within 2 meters of the square
The difference between height and height is less than 2 mm, otherwise the suitable self-flow level should be used for leveling.

3. Site pre-treatment:
To deal with the problems found in the surface inspection.
IV. Self-leveling Construction
1. According to the situation in the field, the construction process of cementing automatic level is referenced.
(Self-flow level thickness is 2mm, if ground condition is bad, the thickness of self-flow level should be adjusted on site)
2, immediately after the construction, please close the site, no walking for 5 hours, 10 hours to avoid heavy impact,
Carpet laying in 24 hours.
In winter, the laying shall be done 48 hours after the construction of self-leveling, and the indoor temperature shall be kept above 15 degrees before the paving.
If it is necessary to grind and polish the self-flow level, it should be done after drying.
Preparation of tools:
1. Cutting tools, shovels, ink, tape measure, edge knife, art knife, steel ruler, etc..
Cleaning tool vacuum cleaner, rag, shoe cover, mop, broom, etc..
Bonding material Hanggao K188 / Domestic high quality floor adhesive

Prelaying and cutting
1. All Silari woven carpet should be prelaid, that is, pre-cut and cut according to room size and laid flat on site for 24 to 48 hours(winter room temperature should be up to the standard, 48 hours), so that the material memory reduction, temperature is consistent with the construction site.
2. Spread out the carpet. The two rugs overlap with each other by 5cm, then cut in the middle along the overlap area.
As far as possible, the length of the carpet should not exceed 8 meters during construction, so as to avoid uneven contact between the carpet and the ground. (Proposal for advance construction drawings)
The carpet used in the same space must have the same batch number.
7. Carpet paving

1, please choose to use German Hankao environmental protection water glue and professional tools, or use high-quality domestic brand adhesive, the glue laying activated carbon carpet should be tested before use. If you need to use other brand glue after testing.
2. Roll up half the length or width
The carpet, start scraping the glue, then spread the floor
The carpet, and with the cork roll back and forth from the middle
Rub the edges and squeeze out bubbles. Two edges.
Try to get close.
3, block material pasting, please turn the block from the middle to both sides, the same ground and carpet back clean after glue paste.
4. Roll the carpet evenly with 50 or 75 kg steel rollers and
In time to repair the stitching edge.
5. After laying it, it can be used until it is completely dry. (48 hours)
Different adhesives will require different requirements during construction. Please refer to the corresponding product specification
