【Factory Floor】Permeable Concrete Surface Strengthening ◎ Case Study ◎ Seal Hard

We applied 【Seal Hard W】 to the floors of a first section listed company on the Tokyo Stock Exchange. This special finish includes joint filling and oil absorption suppression agents. It is a floor that protects the operation and functioning of the factory.

We constructed the factory floor that was newly established between 2019 and 2020. We applied [Seal Hard W, Petrotex, SSP100] for a company that manufactures industrial robots. This company has incorporated various flooring solutions up to the present. As a result of continuing with painted floors, they were troubled by high costs, peeling, lifting, and oil stains. Our company had products that could contribute to solving these issues. Seal Hard specializes in preventing peeling and lifting. Furthermore, to achieve a stronger floor, we divided the construction period into two phases with a W specification, boasting 1.4 times the wear resistance of the standard specification. Petrotex, made from oil absorption-reducing and permeable materials, can reduce damage from water and oil, serving as a countermeasure against oil splashes in factories. Additionally, to suppress cracks, we performed joint cutting followed by joint filling. SSP100 is one answer to preventing debris blockage and handling induced joints. It is a micro-elastic joint filler that follows concrete shrinkage. In factories with heavy traffic, corner chipping is inevitable, and this product helps prevent that. This has resulted in one of the highest quality concrete finishing floors in Japan. With such a high-quality floor, maintenance becomes extremely easy.

[Official HP] Seal Hard - Penetrating Concrete Surface Hardener

basic information

Seal Hard is a colorless, odorless, and environmentally friendly concrete surface hardener that is non-polluting. It is a colorless and transparent liquid primarily composed of sodium silicate. After application, it penetrates the surface of the concrete and undergoes a chemical reaction with the concrete components, generating a glass-like substance on the surface. This chemical reaction continues over time with regular water washing that replenishes moisture. Concrete strengthened by Seal Hard becomes more beautiful and glossy with use and regular washing, enhancing its shine without becoming slippery. Seal Hard W is widely used in warehouse and logistics center floors. The first application can be done after 7 days from the concrete pouring. The second application requires a curing period of at least 14 days after the first application. Additionally, maintenance remains easy and, due to polishing, results in a strong floor that is even more resistant to dirt, just like the standard specifications.
