"Permeable Concrete Surface Hardener RC Gardex PROTECT" is a surface hardener primarily composed of alkali silicate that penetrates the concrete surface, gradually reacting with calcium ions in the concrete to produce calcium silicate, thereby hardening and densifying the floor surface. Additionally, because it integrates with the concrete, unlike paints and similar products, it does not peel off, and its effects continue semi-permanently. It prevents dust and reduces maintenance efforts. As the concrete surface becomes denser and its strength increases, deterioration is suppressed, resulting in minimal dust generation and reduced cleaning efforts. The surface hardener excels in enhancing the strength and stain resistance of the concrete surface. Therefore, it is applicable in areas with heavy foot and vehicle traffic, such as logistics centers, various warehouses, stores, parking lots, factories, convention halls, and airports, as well as in maintenance shops that are prone to certain types of chemical damage. For more details, please contact us or refer to the catalog.

The penetrating concrete surface protector 'RC Gardex PROTECT' is a surface protector primarily composed of alkali silicate that penetrates the concrete surface, reacts with calcium ions in the concrete, and generates calcium silicate and other compounds within the concrete's pores, making the concrete surface hard and dense. This results in features such as 'improved abrasion resistance, durability, and waterproofing,' 'prevention of hairline cracks,' 'dust prevention and reduced maintenance effort,' 'stain resistance,' 'cost-effectiveness,' and 'safety' (while waterproofing is improved, it is not a waterproofing material). The surface protector is excellent for protecting concrete (extending its lifespan), making it ideal for concrete structures that will be used for a long time. The concrete will appear wet after application. For more details, please contact us or refer to the catalog.

The gel structure is also flexible, resulting in less expansive force and improved durability against freeze damage. For more details, please contact us or refer to the catalog.

• Waterproofing work
• Tile work

Tile exterior walls are recognized for their design and durability, and now many apartment buildings standardize tile finishes. However, issues such as peeling, cracking, water leakage, and efflorescence (white bloom phenomenon and dirt streaks) arise due to aging and some construction problems, which have become a source of concern. These phenomena occur due to shrinkage, temperature changes, and moisture content changes that lead to relative deformation between layers, as well as freeze-thaw cycles affecting the concrete structure, base mortar, and the mortar and tile interface. "RC Gardex for Tile Exterior Walls" penetrates from the tile joint area into the concrete structure without compromising the tile's design. It reacts with calcium ions and other substances in the pores through silicate, providing long-term expectations for "high waterproofing performance," "prevention of salt damage and freeze damage," "suppression of carbonation," "crack repair," and "prevention of efflorescence." Additionally, the reaction products form an inorganic polymer gel, which is very effective in suppressing tile peeling (initial) and inhibiting carbonation.
