Goodcrete Concrete Sealer(Floor Hardener)

Professional Manufacturer, Core Technology!
International First-class Quality, But Competitive Price!

Provide OEM service.

Goodcrete Concrete Sealer (other name: Floor Hardener, Concrete Hardener, Concrete Densifier, CS) is a 

lithium-based, inorganic silicate chemical solution especially for the sealing/hardening/dustproofing etc of 

some floors, it's colorless, odorless, environment friendly, non-toxic, non-flammable, free of VOC and easy to 

use. It produced by inorganic silicate, catalysts and other additives through high temperature emulsification. 

It is a low alkaline active-copolymer, can efficiently penetrate into the concrete structure, seal the pores and 

continually  increase the floor's hardness, strength, friction coefficient and  service life, and after polishing, can get the floor an immediate and permanent gloss.


Absolutely environment friendly, colorless, odorless, non-toxic, non-flammable, release no VOC, easy to use.

Functions and Benefits:  

01. Lasting sealing, hardening, anti-permeating, dust-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 new floors' cracks and stains.

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

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

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

10.  Become integral part of the floor.

11.  Easy, fast and safe to use, efficiently reduces the labor cost and maintanance 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:

1. Clean the surface, thoroughly remove dirt, oil, laitance, coating, paint or any contaminants that retard Concrete

    Sealer penetrating into the surface, if necessary could use polisher to coarsely grind the floor first to open the pores.

2. For new poured concrete, construction need after at least 7days curing.

Method of Using: 

1. Shake well before using.

2. Coverage: About 3-5m2/kg.

3. If a matt surface is wanted:

Spray(or brush/roll) CS evenly and wet the concrete surface, keep the surface wet at least 30minutes, the area become  dry too quickly, need an immediate additional spraying.

4. Air temperature at 5-35℃, and relative humidity 10-90% is the best, when temperature >35℃, please sprinkle water  to cool down the surface first.

5. If a gloss surface is required, please refer to following process:

   1). Coarsely grind the floor by 50-200mesh (wet or dry grinding) abrasive disc;

   2). Spray CS evenly on the floor, coverage: 0.1-0.2KG/m2, keep the floor wet at least 30minutes;

   3). Grind to 400mesh (wet or dry grinding);

   4). Polish to 800mesh (dry polish);

   5). Spray CS again, coverage: 0.1KG/m2;

   6). Polish to 1500-2000mesh (dry polish);

6. Avoid the surface suffer from water, rain and freeze within 24h after construction, after 4hours, the floor can be walked on, and after 7days, the treated surface can be open to heavy traffics or start following works.


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.
