3. The site must be surrounded by a complete drainage system and must have an open channel design.
4. The site shall be designed with single-sided drainage, and the drainage slope shall reach 4-8.
5. The flatness shall not exceed 3mm when measured with 3m highway ruler.
6. There is no cracking, sand and powder on the surface of the ground base.
7. The new cement ground base must be hardened after 30 days (winter time 1-2 times), before the site can be laid.
8. Before laying the pitch, the pitch must be acid-washed and sanded to ensure that the base surface is free of any grease, oil, dust, mud and other debris.

Two, asphalt ground base requirements
1. The ground base must be laid with hot melt asphalt, and emulsified asphalt is prohibited. The mixing ratio of hot melt asphalt paving shall be in accordance with the national standard of secondary highway and above.
2. The site must be surrounded by a complete drainage system and must have an open channel design.
3. The site shall be designed with single-sided drainage, and the drainage slope shall reach 4-8.
4. The flatness shall be measured with a 3-meter highway gauge and the error shall not exceed 3mm.
5. Asphalt surface without peeling loose and cracking.
6. New asphalt must be hardened for 20 days before it can be laid on the site.
7. Before laying the pitch, ensure that the base surface is free of grease, oil, dust, mud and other debris.
8, only to lay a good foundation to make durable court material surface.

Construction process:
The base surface treatment → laying elastic layer → laying strengthening layer → laying wear-resistant surface layer → marking → clearing the field is completed.
First, the base surface treatment
Before construction, the site shall be pickling, grinding and filling, and the curing period shall be no less than 20 days.
Two, laying elastic layer
With TB100 (solvent can be added to adjust the construction consistency), with flat scraper or tooth scraper laid on the base surface, each laying thickness can not exceed 1.5mm, each laying time interval before a dry solid shall prevail (generally about 10 hours, specific depending on the site weather conditions), until laid to the required thickness. [Note: After the elastic layer is laid and dry solid, the ground flatness shall be tested by the water standing method. The water standing shall be repaired and then the reinforcing layer shall be laid.]
Three, laying strengthening layer
With TB200 (solvent can be added to adjust the construction consistency) with rubber scraper in two laying about 0.8mm thick on the elastic surface, laid after the surface is smooth.
Four, laying wear-resistant surface layer
PB-3 according to A component: B component: special sand = 9:1:5 fully mixed stirring evenly, laid on the strengthening surface, generally laid two. (Smooth surface can be made without special sand)
Five, the cross line
Measure and position according to the standard size, mark the line position with canvas line, and then paste the line on the court with the beautiful pattern paper along the canvas line, mix it with the special marking paint G008 in proportion, and brush it evenly between the two beautiful pattern paper with a brush, and tear off the beautiful pattern paper when the material surface is dry.
Six, the completion of clearing.

Precautions for use:
● When mixing the material, it must be weighed accurately and stirred evenly.
● The whole process of construction each working procedure must be kept clean before construction.
● Indoor site must ensure good ventilation effect.
● The site should be maintained for more than 5 days after laying before it can be put into use.
● It is strictly prohibited to wear leather shoes, high heels or easy to drop the color of sports shoes.
● It is strictly prohibited to cut and squeeze. The surface should not be rubbed with hard objects to avoid damage or rupture.
● It is strictly prohibited to use acid, alkali and other corrosive chemicals on the floor and keep away from fire and high temperature, so as to avoid deformation of the floor.

Construction and maintenance period:
1. After the completion of laying, it is necessary to maintain the ground material for 10-15 days before it can be used
2. During the construction and maintenance period, personnel should be prohibited to walk around, trample, wear and tear
3. During construction and maintenance, it should be prevented from standing water for a long time and cloudy tide.
4. During maintenance, air bag, cracking and other situations should be repaired by construction professionals in time.
5. If the weather is cloudy or wet for a long time or in winter, extend the maintenance period appropriately
6. After the maintenance period, due to the new characteristics of the material, it can be very good waterproof, ultraviolet protection, wear resistance and so on.

Service life maintenance:
1. The plastic court can be used all weather under the condition of certain drainage facilities.
2. The plastic court shall only be used for athletes' training and competition, sports and fitness exercise, and shall not be used for other purposes.
