Goodcrete Concrete Sealer(other name: Floor Hardener, Concrete Hardener, Concrete Densifier, CS) is a water-base, 
inorganic concrete sealing/hardening/dustproofing/gloss generating chemical solution for some floors, it subdivides 
into Lithium-based Concrete Sealer, and Sodium-based Concrete Sealer.

Characteristics:
Environment friendly, colorless, odorless, non-toxic, non-flammable, release no VOC, easy to use.

Functions:  

01. Lasting sealing, hardening, anti-permeating, waterproofing, dirt-proofing; 

02. Anti-corrosion of acid, alkali and salt; 

03. Improving concrete floors compressive strength, friction coefficient, wear-resisting;

04. Anti-skidding, anti-tyre-marks;

05.  Reducing cracks and stains.

06.  Prolong the service life of finishing coating and the floor.

07.  After polishing, an immediate marble like gloss will appear and it will last forever.

08. The treated floor is easy to clean and maintain, and the color of the treated floor is not changed.

09.  Easy to use, efficiently reduces the labor cost and maintanance cost.

Benefits:
1. Environment friendly;
2. Easy to use,  efficiently reduce the labor cost;
3. Permanent function of sealing, hardening and anti-permeability etc after one-time application;
4. Giving the concrete structure all-sided protection so that largely decrease  the repair and maintenance cost.

 

Working Principle: 
Through the pores, Concrete Sealer penetrates into the concrete floors, reacts with the free calcium(Ca+), free 
potassium(K+)etc, then continuously generates calcium silicate hydrate, which finally solidifies and becomes an 
integral part of the concrete structure. In short, through filling in the pores and increasing the density of the 
floors it can play a role of hardening /sealing/dust-proofing/anti-skidding/anti-permeability/anti-corrosion.

Surface Treatment Before Using Concrete Sealer:
01. Freshly Finished Concrete Floor: No treatment need. 
02. Old Concrete Floor: To grind the surface even, repair the cracks, then sweep or scrab the surface clean to ensure 
     the Concrete Sealer can efficiently penetrate the surface.

Method of Using: 
1. Shake well before using. 
2. Apply with low-pressure sprayer, brush or roller to spray/brush/roll directly on  the clean concrete surface, application
    temperature at 5-35℃, and relative humidity 10-90% is the best. 
3. The areas that becomes dry too quickly, need to proceeds the second spraying immediately.

Coverage: 
Approximately 3-5m2/kg(150-200square feet/gallon), according to different quality and tightness of the concrete floor, 
the coverage is different.

Applicable Places:
Concrete floor, cement-mortar floor, color aggregate floor, emery floor, terrazzo floor, and self-leveling floor, whatever 
below and above ground, indoors and outdoors, new or old.

Limitations:
A. Not suitable for lightweight blocks, porous masonry etc similar products. 
B. Floors previously treated with curing or sealing agents, unless these coatings have completely worn off or have been
    removed by chemical or mechanical means.

Clean Up:  By soap and water.

Packing:  20kg/pail, 220kg/barrel(=5gallon/pail, 55gallon/barrel)

Storage Life:  Unlimited shelf life in the original and sealed condition.
