"Portuguard Plexus" is a composite silicate-based surface impregnation material made by mixing silicates and auxiliary components. It penetrates the fine voids of concrete substrates through an inorganic impregnation system, modifying and densifying the structure of the substrate's surface layer. It excels in water resistance, durability, and chemical resistance, effectively improving waterproofing, preventing carbonation, suppressing erosion from chloride ions, enhancing freeze-thaw resistance, and preventing efflorescence. [Features] - Penetrates the fine voids of PC concrete materials, modifying and densifying the structure of the substrate's surface layer. - Reacts with calcium ions to produce C-S-H crystals and sodium hydroxide, filling fine voids. - By impregnating this product, its components crystallize with the unreacted parts remaining on the concrete surface, modifying and densifying the PC concrete. - As an inorganic impregnation material, it is also environmentally friendly. *For more details, please refer to the PDF document or feel free to contact us.*

The "Portuguard AF System" is a protective method that can maintain the texture of concrete (design quality) for an extended period. It uses a water-based fluororesin clear coat for the top layer, which has low contamination and excellent weather resistance. The coating has oil-repellent and hydrophilic properties that reduce the adhesion of contaminants, making it easier for them to wash off with rainwater. Two types of topcoat materials are available: "completely matte" and "30% gloss." 【Features】 ■ Suitable for substrates such as exposed concrete, PC boards, and extruded cement boards. ■ Allows for pattern color adjustments and localized coloring that blends seamlessly with the exposed finish. ■ Color clear finishes can be customized to match the building's use and design. ■ The materials used are registered as F☆☆☆☆. ★ We are currently seeking cooperative contractors (individuals are welcome). Please feel free to contact us. You can view the catalog and photo collection of achievements via "PDF Download."
