Impact on the durability of the coating / Preparation of the substrate is necessary.

Impact on the durability of the coating / Preparation of the substrate is necessary.

Proper adjustment of the substrate is essential for maintaining the durability and lifespan of the paint.

The lifespan of metal coatings is generally considered to be around 10 to 30 years. The factors that influence this lifespan can be broadly categorized into the following four: Surface Preparation: Proper adjustment of the metal surface before painting is crucial. Cleaning and treating the surface improves the adhesion and durability of the coating. Number of Coats: It is also important to adhere to the appropriate number of coats. Ensuring sufficient coating thickness enhances the corrosion resistance of the metal. Type of Paint: The type of paint used significantly affects the lifespan. It is necessary to select appropriate paint that matches the metal's usage environment, considering factors like weather resistance and chemical resistance. Painting Techniques, Climate, and Surrounding Environment: The skills used in the painting process and the construction environment are also important factors. By employing appropriate painting techniques and considering climate conditions and the surrounding environment, the quality and lifespan of the coating can be improved. By properly managing these elements, the lifespan and corrosion resistance of metal coatings can be maximized. For more details, please refer to the PDF below.

Primer required, prevents peeling.

Primer required, prevents peeling.

If you apply topcoat paint without a primer, it will peel off. Compared to products that have both primer and topcoat, those without primer have weaker adhesion to the substrate, making the paint film more prone to peeling.

When comparing products that only have a topcoat without a primer to standard painting products that include a primer, it was found that the products without a primer easily had their paint film peel off. Primer paint has the dual effect of preventing rust and strongly adhering to the substrate and base material, so it cannot be omitted. Although the primer is not visible, it plays an important role in maintaining corrosion resistance. Additionally, if the primer is not applied properly, the topcoat may be applied unevenly or show inconsistencies, resulting in an unattractive finish. Furthermore, the primer enhances the permeability of the paint, allowing the topcoat to adhere better, which can improve the durability and anti-corrosive properties of the paint film. In other words, the primer is a crucial step that significantly affects not only the appearance but also the performance and lifespan of the paint. Therefore, omitting the primer greatly increases the likelihood of having a paint job that peels easily or products that are prone to rust, making it essential to always apply an appropriate primer.

The relationship between blasting and painting.

The relationship between blasting and painting.

In painting, proper surface preparation (substrate treatment) is essential to achieve a good finish. The most effective method for surface preparation is blast treatment.

"Surface preparation" refers to the process of preparing the underlying material or substrate. Metals are melted, cooled, and solidified during the manufacturing process, but when exposed to high temperatures, they combine with oxygen in the atmosphere to form a film known as an oxide layer. If painting is done without removing this oxide layer and impurities, contaminants will mix between the paint and the substrate, leading to poor adhesion. Additionally, the functionality of the paint will not be realized due to the influence of impurities, preventing it from performing as intended. However, by using blasting to prepare the substrate, the surface oxide layer, rust, and other contaminants can be completely removed. Furthermore, by using angular abrasives, countless fine irregularities are created on the substrate, increasing the surface area for paint adhesion and preventing peeling. By cleaning and preparing the substrate with blasting before painting, the lifespan of the paint film can be extended two to three times, providing long-term economic benefits.

Magnetic High-Pressure Water Stop "DP-SW Method"

Magnetic High-Pressure Water Stop "DP-SW Method"

Revolutionary method for deck slab water leakage! With pinpoint waterproofing, leakage can be stopped in as little as one day.

The "DP-SW Method" is a groundbreaking technique that allows for water stoppage in deck slabs, which were previously considered impossible to seal. It utilizes a combination of ultra-strong neodymium magnets and high-pressure injection plugs, approaching the water leakage from the outlet. Water leakage that reaches the deck plate through cracks in the concrete of the deck plate floor is not only difficult to identify the leakage path but can also cause the deck plate to shift sideways, leak from various points, spread rust, and cause the concrete to swell, leading to further leakage. In large commercial facilities and buildings, extensive investigations and construction can be challenging due to structural constraints. Our company addresses issues related to water leakage, especially when full waterproofing is not feasible due to time and cost constraints. 【Features】 ■ Uses GSC's uniquely developed magnetic high-pressure plugs ■ Fixed in place using magnets at leakage points such as ceilings for work ■ Minimizes the construction area by approaching from the leakage outlet ■ No need for extensive investigations; partial water stoppage work reduces construction time and costs ■ Reduces stress on the building compared to conventional methods, extending the building's lifespan *For more details, please refer to the PDF document or feel free to contact us.

Roof sheet waterproofing method "High Tough EG"

Roof sheet waterproofing method "High Tough EG"

Contributing to energy savings with a lightweight external insulation sheet waterproof system.

"High Tuff EG" is a comprehensive system that includes total design from the base deck plate, insulation board, High Tuff EG sheet, to accessories (High Tuff Metal), all constructed by our qualified professionals with responsibility. The High Tuff EG sheet uses a waterproof sheet made of ethylene propylene rubber as the main material, laminated with a strong polyester mesh, excelling in "weather resistance, impact resistance, and wind pressure resistance," while also considering the global environment. Additionally, by employing a mechanical fastening method that secures the sheet and insulation board with dedicated fasteners, and a hot air fusion method that integrates the overlapping parts of the sheet with hot air, we have eliminated issues such as bubbling and peeling of the waterproof sheet, which are drawbacks of conventional roofing waterproofing methods. With the installation of the High Tuff EG Solar Frame (related product), it becomes possible to install solar panels on the sheet waterproof roof (High Tuff EG). [Features] ■ A comprehensive system from deck to waterproofing (responsible construction by our company) ■ High weather resistance, high impact resistance, high wind pressure resistance, high water tightness ■ Energy-saving effects ■ Lightweight roofing ■ Mechanical fastening method, etc. *For more details, please download the PDF or feel free to contact us.
