1. The quality of the concrete tennis court depends largely on the quality of the foundation. The concrete foundation should be marked with C20 or more and its thickness should be 150mm.
Flatness is good. Drainage gradient is 3‰-5‰. In the middle of the court, there is a 5MM expansion gap. Use straw or plastic film to cover the maintenance for 28 days.
2. Asphalt foundation (asphalt concrete)
Asphalt base structure: First, it is compacted and compacted with lime-soil—rolled with inorganic material and rolled—and laid with asphalt. Drainage gradient is 3‰-5‰. Four roads will be paved with road teeth and embedded pieces will be embedded. Maintenance of 7 days hard acrylic tennis court construction process:
Asphalt base ground DecoTurf® hard acrylic construction process:
1. Test the water: Test the water on the court and test the flatness of the site. After one hour of watering, mark with chalk in the sag water more than 3mm. Do not use crayon or oily pen to avoid contamination of the asphalt ground.
2. Filling up: Fill up one or two roads with professional materials to make the floor meet the flatness requirement of the tennis court so that the height difference between any two points per square meter is less than 3mm.
3, base coating: the use of professional primer material scratched the second floor of the entire field to make the ground more uniform, dense, and enhance the combination of the ground and the coating.
4. Reinforcement layer: Scrap the entire layer with acrylic filler to mix 60-80 mesh quartz sand. Stir thoroughly and apply with an imported rubber squeegee. Provide a uniform, dense cushion on the bottom layer to increase the strength of the course. It takes about 24 hours to dry.
5, texture layer: Acrylic speed control material mixed with acrylic color material after adding water The whole field scratching two acrylic speed control material is a mixture containing quartz sand 100% acrylic emulsion. Makes the textured surface thick and durable, improving the function of adjusting the ball speed and wear resistance. It takes 24 hours for each layer to dry and maintain.
6, the final decoration layer: Acrylic color material coated with a layer of acrylic paint color with water, without sand, fully stirred after the scratch. Makes the surface color colorful, with weather resistance and anti-ultraviolet light performance, more beautiful and durable. Drying and curing takes about 24 hours. Texture layer plus finishing layer a total of three layers of pigment.
7ã€Drawing: Measure the alignment line with acrylic white line lacquer to draw the court boundary line according to the international standard. Use the imported gluing machine to glue the tape tightly to the ground to prevent flashing. Brush the acrylic white line paint directly with a brush. Floor.
â—† Flexible acrylic tennis court construction process:
Bituminous Foundation DecoTurf® Acrylic Coating Process Acrylic Coating Finish Preparation:
1. Reinforcement layer: American DecoTurf® Acrylic Resurfacer acrylic filler is coated with a layer of acrylic filler filled with 60-80 mesh quartz sand. Stir thoroughly and apply with an imported rubber squeegee. A layer of homogeneous, dense cushion is provided on the bottom layer to increase the strength of the course and improve the quality of the entire scene. It takes about 24 hours to dry.
2. Elastic layer: Elastic rubber particles are coated with four layers (2 thick and 2 thin)
Crude rubber layer: Scrape with a rubber scraper. The crude rubber particles mixed in the special acrylic acid solution are stable in properties, enhance the flexibility of the course, make the playing more comfortable, and the player is not easily injured.
Fine particle layer: After the fine rubber particles were coated with water, they were evenly mixed and wiped with a rubber scraper. Blended with specially selected fine rubber particles to further increase the elasticity of the course, and level the rough surface of the rough rubber layer, so that the surface layer is even and uniform.
3, texture layer: the United States DecoTurf DecoBaseI acrylic material mixed with acrylic color material scratching the whole floor acrylic speed material is a mixture containing quartz sand and 100% acrylic latex. The diluted mixture can provide a thick and durable textured surface while also increasing the color and strength of the color coating, increasing wear resistance and adjusting ball speed. It takes 24 hours for each layer to dry and maintain. ,
4, finishing layer: American DecoTurf® DecoColor MP Classic acrylic color coated with a layer of acrylic acid dye diluted with water, without sand fully stirred with an imported rubber scraping scraping. Makes the surface colorful and pleasing to the eye, and has a strong resistance to climate and ultraviolet radiation, the ball scene is more beautiful and durable. Drying and curing takes about 24 hours.
Texture layer plus finishing layer a total of three layers of pigment
5, line: United States DecoTurf® White Line Paint acrylic white line painted line boundary line according to international standards for measuring the line, the use of imported adhesive tape machine will tape the line tightly stuck to the ground, to prevent flash, brush directly brush Acrylic white line paint layer.
Acrylic site construction process
Currently popular hard tennis courts (US, Australia) mainly use acrylic paints. According to different hardness and ball speed, can be divided into hard acrylic and elastic acrylic.
