Are you sure you really understand these "hidden rules" in the construction of the parking lot ground?

Now that the society is getting more and more developed, people's requirements for life have become higher. It is common for parking lot construction to be epoxy floors. Epoxy floors are divided into oily epoxy floors and water-based epoxy floors. For flooring with water leakage, oily epoxy flooring cannot be used, because the oily epoxy flooring is dense after sealing, and water vapor cannot be discharged, which will easily cause deformation, hollowing, bubbling and peeling of the floor paint, but it is oily. The gloss of floor paint is relatively water-based, and the price is half cheaper. Therefore, most of the real estate epoxy floors use oily floors.

The base surface treatment is mainly to clean up the floating ash and the loose cement slurry layer. Generally, dry grinding (dust floating everywhere) is used. This process is very critical and directly affects the adhesion between the floor paint and the ground. Or the peeling phenomenon is mostly caused by the poor treatment of the grassroots level, so we must strictly control the quality of dry grinding.

Epoxy resin primer is a component, it is a single component, so it can be used alone without mixing with component B. Generally, it needs to be applied twice to ensure that the primer is effectively combined with the ground and must not be missed. Because the primer is a transparent material, the effect of brushing can be seen at a glance. The epoxy primer bonding layer also seals and waterproofs.

Epoxy quartz mortar is mixed with epoxy sand paint nail component (single component) and quartz sand to fully coat the ground to increase the hardness and strength of the ground. After the quartz sand layer is fully scraped, it is polished and smoothed. After the epoxy mortar layer is completed, dry grinding must be performed, otherwise the ground may be uneven, and more epoxy putty is needed to smooth the surface. It also causes poor flatness of the epoxy floor finish in large-scale construction in the later stage, and the appearance is extremely poor. Good, contrary to the flatness of the model construction, the acceptance of the floor paint may not pass, so we must pay great attention.

Chongqing floor construction workers will see that the paint is colored in the middle of construction, and must use two components. Among them, component A belongs to colored paint and component B belongs to curing agent. It is absolutely impossible to save it halfway, because if the topcoat is applied by brush It is not thick enough to easily penetrate the bottom, or it is easy to peel after the later wear, but the color in the middle must match the top coat, and the thickness of the brush must be ensured in the middle.

The top coat is a key floor construction process. It must be constructed strictly in accordance with the ratio. Otherwise, the paint is easy to be removed at a later stage and the thickness of the brush must be controlled. The thickness of the topcoat is about 1.0 mm. We can't directly measure it with the naked eye or tools, and it's impossible to conduct on-site sampling tests. Generally, we control the thickness of the topcoat by controlling the number of materials entering the site. Generally speaking, oily floor finishes are 0.6 kg / sq. And water-based floor finishes are 0.8 kg / sq., So we must require the number of materials to be registered for inspection to ensure the thickness of the floor finish.
