Long-lasting slippery condition. Resistant to wear and rainwater. Proven track record in both new construction and renovations at famous skate parks.

The "Seal Hard Skate Park Specification" is a construction product provided through the following steps 1 to 4. ◆1. Concrete Grinding (for renovation only) The roughened concrete surface is shaved down to remove surface irregularities. ◆2. Concrete Polishing For newly installed concrete: The surface's trowel marks and fine irregularities are smoothed out to create a surface without roughness. For renovated concrete: The surface, which has had irregularities removed in the previous grinding step, is further smoothed to eliminate grinding marks and fine irregularities, resulting in a surface without roughness. ◆3. Penetrating Surface Hardener Seal Hard This is a concrete surface hardener that is "penetrated" rather than "applied." 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 Inhibitor (Water Repellent) Aquapel Plus This is a concrete surface water absorption inhibitor (water repellent) that is "penetrated" rather than "applied." 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 inhibition effects as long as the surface does not wear down.

A weathered concrete park that has been neglected for 20 years has been revived into a skate park that is even smoother than newly built parks.

Seal Hard Skate Park Renovation Specifications - Surface Concrete Grinding: The uneven surface will be leveled using a large grinder made by American company STI. - Joint Leveling Grinding: The raised joint areas will be ground down using a medium grinder to level the height and eliminate the step. - Joint Filling Repair: Joints that were 10-20mm wide will be filled with American-made fast-setting repair mortar. - Surface Depressions Resin Filling Repair: Areas that remain depressed after grinding will be filled with a special American-made resin. - Surface Concrete Finish Grinding: Finish grinding will be done to create a smooth surface. - Application of Penetrating Surface Hardener Seal Hard: This will enhance wear resistance and create a surface that can withstand wear from skateboarding. - Application of Penetrating Water Absorption Inhibitor AquaPel Plus: This will suppress rainwater penetration and prevent surface deterioration due to rain. - Skateboard Test Run Confirmation: The finished surface will be tested with a skateboard to confirm that it provides the necessary grip for skateboarding. The penetrating concrete surface hardener was weak against rain and had low effectiveness outdoors. Therefore, by combining diamond grinding with the water absorption inhibitor "AquaPel Plus," we have eliminated this weakness and developed a method specifically for skate parks, which is currently under patent application.

A skate park highly praised by skaters with a concrete surface finish. The smooth concrete surface is perfect for skating and lasts long even outdoors!

The "Seal Hard Skate Park Specification" is a construction method product provided through the following steps 1 to 4. [Patent pending] ◆1. Concrete Grinding (for renovation only) The rough concrete surface is ground 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 is "penetrated" rather than "applied." 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) Aqua Pel Plus This is a concrete surface water absorption suppressor (water repellent) that is "penetrated" rather than "applied." It does not create a film on the concrete surface but imparts water-repellent properties to the internal layers, allowing it to maintain its water absorption suppression effect for a long time as long as the surface does not wear down.

"Seal Hard," a penetrating concrete hardener that makes floors shine brightly with just a wash.

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, producing a glass-like substance on the surface. This chemical reaction continues over time with moisture replenishment through regular washing with water. Concrete strengthened by Seal Hard becomes more beautiful and glossy with use and regular washing, without becoming slippery even when glossy. Since Seal Hard penetrates rather than being applied like paint, it does not peel off, and a single application can provide a semi-permanent effect. This, along with ease of maintenance, leads to significant cost savings. Developed by L&M in the United States and currently marketed by LATICRETE, Seal Hard has over 40 years of proven performance in the U.S., where many factories, stores, and logistics centers that have been treated still maintain their beautiful condition. It may be referred to by various names such as concrete hardener, concrete strengthening agent, or penetrating concrete surface hardener.

The floor of the Super Center PLANT Kurobe store was constructed with "Seal Hard Premium." It features a combination of good appearance, high durability, and low maintenance.

Seal Hard is a colorless, odorless, and environmentally friendly concrete surface hardener that is non-polluting. It is a colorless, transparent liquid primarily composed of sodium silicate, which penetrates the surface of the concrete after application and reacts chemically with the concrete components to produce a glass-like substance on the surface. This chemical reaction continues over time with regular water washing that replenishes moisture. Concrete reinforced with Seal Hard becomes more beautiful and glossy with use and regular water washing over the years. Even when a gloss develops, it does not become slippery. Seal Hard Premium is widely used in commercial facilities and public property floors. In addition to the commercial facility examples introduced this time, there are numerous achievements in public and private properties, including art museums, museums, and logistics centers. The application of Seal Hard is done in two parts. The first application can be done after the eighth day following concrete placement, and the second application can be done at least 14 days after the first application. Due to the inclusion of polishing in the specifications, the surface is finished to be smooth and glossy from the time of completion, and maintenance is very easy. It results in a glossy floor while retaining the texture of the concrete.

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.
