Brief Introduction:

Goodcrete Nano 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 and  service life, and after polishing, can get the floor an

immediate and permanent gloss. It divides into Lithium Silicate Concrete Hardener, Sodium Silicate Concrete Hardener.

Characteristics:

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

Technical Data:

Appearance: Colorless, odorless clear water like liquid

Solid Type: Lithium silicate

PH value: 11

Freezing Point(°C): 0°C

Specific gravity: 1.1g/cm3 

Flash Point(°C): Non flammable

VOC Content: Solvent-free; zero VOC

Service Life:  25 years

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.

08.  If not polishing, the gloss will gradually appear after  natural walk for a period of time.

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.

Coverage: 

For C25 or above concrete floor, about 3-5m2/kg(150-200square feet/gallon), 

For terrazzo floor, about 6-8m2/KG.

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.
