Flooring has become a common item in our daily lives, now widely used for decorative purposes. Not only is it aesthetically pleasing, but its affordable price also saves a significant amount of money. Flooring is also durable and withstands the test of time. Indoor flooring and outdoor flooring are typically categorized in civil engineering projects. Outdoor flooring usually refers to the construction layer applied after the initial base is leveled (through excavation or backfilling). This construction layer includes the original soil, sub-base, intermediate layer, and surface layer. The design elevation for indoor and outdoor flooring is determined by the designer based on the initial geological elevation and the building's function, usually indicated by a filled triangle with numbers. Indoor flooring follows a similar construction process to outdoor flooring but is affected by its application, resulting in differences in strength, thickness, and materials compared to outdoor flooring. This is why we differentiate between indoor and outdoor flooring. Some customers may complain about the poor performance of certain epoxy flooring, but sometimes the issues with the flooring are not due to its quality but rather to poor system design choices influenced by environmental factors. For instance, indoor flooring, if used outdoors, would significantly reduce its lifespan. Indoor and outdoor flooring have different selection criteria. Generally, outdoor flooring must have good weather resistance, while some flooring products may have excellent wear resistance, high cleanliness standards, or excellent corrosion resistance but poor weather resistance, which can lead to fading, cracking, and other issues over time, significantly shortening its lifespan. Therefore, when choosing outdoor flooring, it's crucial to consider its weather resistance and select the appropriate flooring product based on different needs. For example, UV-resistant flooring should have excellent weather resistance, while permeable flooring should have good weather resistance and excellent water absorption capabilities. Indoor flooring, on the other hand, does not need to consider weather resistance and should be selected based on specific needs. If corrosion resistance is required, choose a corrosion-resistant floor coating; if an anti-static environment is needed, consider epoxy anti-static flooring, and so on.
