Inquire About This Product
basic information
The "Seal Hard Skate Park Specification" is a construction method product provided through the following steps 1 to 4. [Patent pending] ◆1. Concrete Grinding (Renovation only) The roughened concrete surface is shaved down to remove surface irregularities. ◆2. Concrete Polishing For newly installed concrete: Smooths out trowel marks, trowel lines, and fine irregularities on the surface to create a smooth finish without roughness. For renovated concrete: Further smooths out grinding marks and fine irregularities from the surface that has been made even in the previous step, creating a smooth finish without roughness. ◆3. Penetrating Surface Hardener Seal Hard This is a concrete surface hardener that "penetrates" rather than "coats." It provides strong dust resistance and wear resistance to the concrete. Since it does not create a film on the concrete surface but densifies and strengthens the internal layers, it results in a concrete floor finish that is free from peeling. ◆4. Water Absorption Suppressor (Water Repellent) Aquapel Plus This is a concrete surface water absorption suppressor (water repellent) that "penetrates" rather than "coats." It does not create a film on the concrete surface but imparts water-repellent properties to the internal layers, allowing for long-term water absorption suppression effects as long as the surface does not wear down.

Detailed information
-

Surface Grinding A diamond blade is attached to a large grinding machine to remove the weak surface layer in advance and achieve a smooth finish.
-

【Seal Hard Application】 The penetrating concrete surface hardener "Seal Hard" will be applied. With the effect of Seal Hard, the surface of the concrete will gradually harden and change. Since Seal Hard is a non-film-forming penetrating type, it will not peel off. However, penetrating hardeners are vulnerable to rainwater; when exposed to rainwater, the penetrating components can dissolve and wash away.

Cleaning
-

【Application of Aquapel Plus】 The penetrating water-repellent agent "Aquapel Plus" will be applied. By applying Aquapel Plus, we compensate for the weaknesses of seal hard that are vulnerable to rain, transforming it into a strong, rain-resistant concrete. Since it is a non-film-forming penetrating type, it will not peel off.
