Project Features：

1、Hard：After being treated with permeable sealing and hardening materials, the Mohs hardness of the ground will reach 8 to 9, and the Mohs hardness will be increased by about 45%.

2、 Wear Resistance：Permeable sealing and hardening materials can solidify various components in concrete into a hard entity to increase hardness and compactness. After the ground is hardened, the wear resistance will increase to more than 8 times. 

3、Dust Prevention：The permeable sealing hardening material reacts chemically with the silicate in the concrete to form a dust-free and dense whole on the concrete surface, permanently controlling the precipitation of concrete dust from the surface voids. 

4、Anti Slip：On general concrete floors, salt and alkali components can precipitate from the surface, causing slippage. However, the ground with permeable sealing and hardening materials is different. It forms a solid and dense whole on the concrete surface, and salt and alkali components do not precipitate from the surface. 

5、Compressive Strength：The compressive strength of the treated sample is 25% higher than that of the untreated sample, and the flexural strength is also improved.

6、Impermeability：Permeable sealing hardening materials can effectively penetrate into the concrete and react chemically with them, locking the pores inside, providing a permanent sealing effect on the concrete surface, and effectively preventing water, oil, and other surface contaminants from entering the concrete.

7、Weathering Resistance：Water spray has no adverse effect on the treated sample and can effectively prevent the passage of chloride ions. Tests have shown that the treated ground effect will not be affected by exposure to electromagnetic or water mist. 

8、Corrosion Resistance：The ground treated with permeable sealing and hardening materials will greatly improve the corrosion resistance of concrete. 

9、Brightness：The concrete floor treated with permeable sealing and hardening materials will have a marble like luster, and the longer it is used, the better the glossiness.

10、Environmental Protection：Permeable sealing hardening material is a concrete sealing, dustproof, wear-resistant hardening agent that is colorless, odorless, non-toxic, and nonflammable, and can make concrete strong and dustproof.

Construction Process：

Base surface Treatment

First, thoroughly polish the ground with a 50-300 mesh abrasive disc until it feels smooth, and thoroughly clean the ground dust with a vacuum cleaner or other tools to enable the ground pores to fully absorb material;

Spraying Material

Spray 1 to 3 layers of SPR-37102Na reinforced (1:1 water addition)/SPR-37105Li crystalline liquid concrete sealing and curing agent until there are crystals on the surface. Allow it to naturally permeate for 30 to 60 minutes, and then rinse the ground with clean water (crystal clear liquid concrete sealing and curing agent does not need to be washed), and use a floor cleaner to clean the surface crystals;

Preliminary Polishing

After curing (3-6 hours) and drying the ground, polish it 1-2 times with a 500 mesh abrasive plate;

Spraying Materials

SPR-37101C universal type/SPR-37105Li crystal permeable liquid concrete sealing curing agent is evenly coated on the ground with a spray, and the ground is washed with clean water after it reacts for about 10~30 minutes (crystal permeable liquid concrete sealing curing agent does not need to be washed), and the surface crystal is cleaned with a floor washer.

Fine Polishing

Use 800-3000 mesh abrasive discs for fine polishing until the surface meets the requirements for smoothness; If the place with extremely high brightness requirements can use a spray to spray SPR-37207C protective agent. After the surface is dry, it can be polished with resin abrasive disc. Overpolishing should be avoided; If waxing is required, apply the selected floor wax to the floor surface, without excessive application. After drying for about 1~3h, polish with a polishing pad to achieve the required brightness, avoiding excessive polishing.

Place Of Application：

1. Areas that require a clean environment and have certain requirements for dust content in the air, but are not suitable for use as surface coating materials.

2. Any cement based construction material surface such as new and old concrete base, terrazzo, cement based wear-resistant ground, and cement mortar surface that requires hardness, high wear resistance, and high impermeability both indoors and outdoors, such as factories, shopping centers, warehouses, parking lots, service stations, aircraft hangars, freight distribution centers, and other areas.
