Silicon PU is a new generation of stadium materials developed on the basis of PU stadium materials. It is a scientific combination of polyethylene materials and materials containing organic silicon components, which fundamentally and effectively solves the shortcomings of PU stadium materials in terms of easy foaming, environmental protection construction, service life, daily maintenance, etc., and has revolutionary and innovative performance, It is a new generation of environmental protection product replacing two-component PU.

Foundation inspection and repair
Check the compactness of asphalt foundation or the strength of cement foundation, the flatness of foundation and drainage slope, which must meet the foundation requirements of runway specifications. Check whether there are other residues dripping from civil works on the ground, and remove dust. Use quartz sand asphalt repair material to fill uneven places and gaps.
● Primer laying
The components of A and B and granular materials shall be mixed and stirred in the mixing tank according to the required proportion, the amount of catalyst and diluent added shall be adjusted according to the local temperature, and the mixing speed and time shall be controlled. After mixing evenly, the materials shall be paved to the required thickness at one time, and the paving surface shall be plastered with tools to make the surface smooth.
● Cleaning construction
Components A and B (excluding rubber particles and rubber powder) shall be mixed and stirred in the mixing bucket according to the required proportion, the amount of catalyst and diluent added shall be adjusted according to the local temperature, the mixing speed and time shall be controlled, and after mixing evenly, the primer shall be evenly coated with trowel or scraper. The surface is now smoother.
● Self textured finish paint construction
The two-component special self textured surface slurry is prepared in proportion, and is sprayed and paved on the cured clear slurry by airless pressure spraying machine. This layer will form a self textured texture layer before fully curing, and its anti-skid effect after curing meets the standards of IAAF.
● Site marking
Measure and position according to the standard size, apply the scribing paint in two layers, and clean the site when the paint is cured.
Applicable venues: runways around football fields, basketball fields, badminton courts, tennis courts, sports fields, parks, and schools.
