site repair construction, repair the ground and joint filling of expansion joints: the repair ground adopts professional ground repair materials.
(if the ground levelness drop is too large, it can only be remedied by other methods) the next process can be carried out after the repair is completed and the materials are completely dry.
After spraying, the next process can be carried out only after the materials are completely dry.
After mixing the repair materials evenly, scrape and apply them to the marked ponding and repair it flat.
.
pure water-based surface coating material is used for the construction of color surface layer, which is a two-component material ratio (A: B = 1; 0.09).
Construction process of pure water-based silicon Pu course Youzheng sports 18971153177 plastic track course material production and sales + supporting professional construction water cube course project construction adopts pure water-based silicon Pu (WPU) environmental protection materials, which are polymerized from a variety of water-based polymer materials, green environmental protection, non-toxic and tasteless, no toxic smell during production and construction, and no solvent is added, It is more environmentally friendly and durable than oily stadium materials.
the construction of color texture layer coating adopts pure water-based texture layer material, which is a two-component material ratio (A: B = 1; 0.09).
It is the proportion of two-component materials (A: B = 1; 1.25).
Add an appropriate amount of water (depending on the weather) according to the ratio (A: B = 1:1) and apply the scraping process on the surface of cement concrete or asphalt concrete.
The WPU marking coating added and stirred evenly according to the specified proportion (A: B = 1:2) shall be evenly brushed between the two masking papers with a brush, and the masking paper can be torn off after the surface of the marking coating is dry..
After coating and scraping, the next process can be carried out only after the materials are completely dry.
After mixing the waterproof materials according to a certain proportion, they shall be painted on the ground with a roller or scraper.
The construction of reinforcing layer adopts pure water-based reinforcing layer materials.
For the expansion joints, the thermal expansion and cold contraction of the ground in the future shall be considered.
After the construction, the residue of the ground and the dust on the surface of the old cement foundation will be removed.
Measure the flatness of the ground while cleaning, and mark the area with accumulated water of more than 2mm with chalk for later repair.
.
special outdoor waterproof materials shall be used for waterproof treatment construction.
After the texture layer coating is fully cured, mix group A and group B of water-based surface coating evenly according to the specified proportion, and then spray it on the texture layer evenly with roller or spraying machine.
Since the silicon Pu stadium has so many advantages, let’s introduce the construction process of the silicon Pu Stadium: the ground grinding treatment of the stadium.
After the reinforcing layer coating is fully cured, mix group A and group B of water-based surface coating evenly according to the specified proportion, and then spray it on the reinforcing layer evenly with roller or spraying machine.
The marking construction of the court shall be measured and positioned according to the standard size, the line position shall be marked with the canvas line, and then the masking paper shall be pasted on the court along the canvas line.
It can also adjust the durability and softness of materials according to different kinds of courses.
