Generally, the flooring and the coat for the athletic facilities have various purposes such as a tennis, a table tennis, a basketball, a volleyball, a gymnastics, a track and athletics, as well as a group indoor and outdoor athletic field such as a school, an auditorium, a playground.

Such a sports facility coat is made of a material such as sand / earth or made of a solid material such as concrete or asphalt, or is made of a mat for proper elastic repulsive force and shock absorption depending on the use.

However, the coat of the same material as sand / soil is weak in terms of elastic repulsion and impact absorption, and the phenomenon such as dust rupture is severe, and it is difficult to maintain flatness because of a lot of repairs, It is not suitable for game use.

Also, since concrete and asphalt are too hard materials, they are very disadvantageous in terms of elastic reaction force and impact absorption. Matt has weak binding force with the base and is easily influenced by climate change and shrinks and expands, so cracks are formed. Urethane is finished with lower urethane There is a problem that material separation phenomenon easily occurs after construction with materials having different properties from acrylic surface layer.

In the present invention, a glass fiber fabric is provided to prevent cracking and enhance durability. In particular, the mesh-type glass fiber fabric has an effect of preventing the cracks of the flooring as a whole by enhancing the bonding with the base layer and strengthening the bonding with the lower latex layer by penetrating the acrylic resin layer between the mesh spaces.

The lower elastic layer was formed on the glass fiber fabric by applying an acrylate latex containing ethylene propylene diene monomer (amorphous macromolecule) particles having a size of 0.5 to 1.0 mm as a raw material for forming an elastic layer in the acrylic resin.

The upper elastic layer was formed on the lower elastic layer by applying an acrylate latex mixed with ethylene propylene diene monomer particles having a size of 0.5 mm or less as a raw material forming an elastic layer in the acrylic resin.

For elasticity layer construction according to the size of rubber particle, and durability / abrasion resistance / stability etc., the elastic layer is applied once for the adjustment of coat characteristics such as precision construction for flatness / uniformity, repulsion elastic force / It is more preferable that the application and curing operations of the acrylic resin containing rubber particles are carried out alternately by repeating a plurality of times.

First, the curing period of the asphalt should be at least 14 days before applying the acrylic acrylic flooring. The surface layer should be free of foreign substances such as oil and cement, because it weakens the adhesion between the acrylic material and the base layer. Water is poured and removed from the surface layer before applying the acrylic, and the portion buried 2 to 3 mm deep is displayed after 1 hour with a pencil or the like. But do not use crayons or oil pens.

b) forming an acrylic resin layer (200) for partial planarization on the aligned base layer
