Color steel tile can be renovated, color steel tile as a widely used building material, due to its excellent durability and aesthetics, by the majority of users. However, over time, the surface of the color steel tile may appear rust, aging and other problems, affecting its service life and appearance. At this time, it is necessary to renovate the color steel tile.
First, the choice of special paint for the renovation of color steel tiles.
The selection of special paint for the renovation of color steel tiles is the key to the renovation project, which needs to be comprehensively considered according to the surface condition, use environment, aesthetic requirements and other factors of color steel tiles. Generally speaking, the special paint for the renovation of color steel tiles needs to have anti-rust, anti-corrosion, wear-resistant, anti-aging and other properties, and also need to have good adhesion and hiding power. Commonly used special paints for the renovation of color steel tiles include: water-based paint, oil-based paint and powder coating.
Second, the construction technology of color steel tile renovation.
The construction process of color steel tile renovation mainly includes grinding, rust removal, painting and other steps. The following is the specific construction process:
Grinding: Grinding is the basic step of the renovation of color steel tile, mainly through sandpaper or grinder to remove the old paint film and rust on the surface, so that the surface of the substrate is smooth and flat, providing a good foundation for subsequent coating. When sanding, you need to be careful not to over-sand, so as not to damage the substrate.
Rust removal: Rust removal is a key step to ensure the quality of the coating. For slightly rusty color steel tiles, rust removal can be carried out by applying anti-rust primer after light grinding;For seriously rusted color steel tiles, you need to use sandpaper or a shovel blade to remove the rust before painting.
Painting: Painting is an important step in the renovation of color steel tiles, including two parts: primer coating and topcoat coating. Primer coating can improve the adhesion of the substrate to the topcoat and prevent corrosion;Topcoat coating can play a beautiful and protective role. When painting, it is necessary to apply the primer-topcoat sequence, and each layer of paint needs to be dried before the next layer of paint.
Cleaning: After the painting is completed, the construction site needs to be cleaned up, and the residual paint and garbage will be cleaned up to keep the construction site tidy.
3. Precautions for the renovation of color steel tiles.
The following points need to be paid attention to when carrying out the renovation of color steel tiles:
Before construction, the surface of the substrate needs to be inspected and treated to remove oil, impurities and old coatings on the surface
When painting, it is necessary to apply the primer-topcoat sequence, and each layer of paint needs to be dried before the next layer of paint.
During the construction process, it is necessary to maintain good ventilation to avoid personnel poisoning and fire accidents
After the painting is completed, the construction site needs to be cleaned up to clean up the residual paint and garbage;
In the construction process, it is necessary to pay attention to safety issues and take corresponding protective measures to avoid accidents.
