Product Name: Like Nu Concrete Restoration Mix

Description: Developed and refined over 30 years of use in the commercial concrete restoration market. Like Nu is a ready to mix blend of modified cement and our proprietary chemical binder. This unique formula allows the material to be applied with a garden pump sprayer instead of commercial squeegee and trowel making it ideal for homeowner use.

Chemical Composition:

Calcium Oxide (CaO)

Silicon Dioxide (SiO2)

Aluminum Oxide (Al2O3)

Iron Oxide (Fe2O3): 0.5-6%

Magnesium Oxide (MgO)

Sulfur Trioxide (SO3): 1-3%

Other Minor Constituents: Potassium Oxide (K2O), Sodium Oxide (Na2O), Titanium Dioxide (TiO2)

Physical Properties Powder:

Color: Gray

Fineness: Typically passes through a 325 mesh sieve (approximately 45 microns)

Specific Gravity: 3.10-3.25

Physical Properties Liquid Solution:

Color: Cloudy White

Applications:

Concrete Restoration: Like Nu is used to restore concrete to its natural grey finish.

Handling and Storage:

Store in a dry, cool, well-ventilated area away from sunlight, moisture and humidity.

Do not store near flame.

Do not freeze.

Protect from direct sunlight and extreme temperatures.

Avoid contact with eyes, skin, and clothing. Use appropriate personal protective equipment (PPE) when handling.

Follow proper lifting and handling techniques to prevent injury.

Precautions for Safe Handling: Do not breathe dust. Do not get in eyes, on skin, or on clothing. Wash hands and other exposed areas with mild soap and water before eating, drinking or smoking and when leaving work. Avoid contact with eyes, skin and clothing. Handle empty containers with care because they may still present a hazard. Do not handle until all safety precautions have been read and understood. Cutting, crushing or grinding hardened cement, concrete or other crystalline silica-bearing materials will release respirable crystalline silica. Use all appropriate measures of dust control or suppression, and Personal Protective Equipment (PPE).

Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures.

Safety Precautions:

Avoid inhalation of dust. Use respiratory protection in dusty environments.

Wash hands thoroughly after handling. Do not eat, drink, or smoke while working with cement.

In case of contact with eyes or skin, rinse immediately with plenty of water and seek medical attention if irritation persists.

Wear gloves impervious to water to prevent skin contact. Wear safety glasses or  goggles when handling concrete to prevent contact with eyes. Wearing contact lenses, when using concrete, is not recommended. Wear gloves impervious to water and protective clothing to prevent skin contact. Wear respiratory protection (i.e. mask).

Description of First-aid Measures First-aid Measures General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label where possible).

First-aid Measures After Inhalation: When symptoms occur: go into open air and ventilate suspected area. Obtain medical attention if breathing difficulty persists. Inhalation of gross amounts of modified cement requires immediate medical attention.

First-aid Measures After Skin Contact: Remove contaminated clothing. Brush off, then immediately flush skin with plenty of water for at least 60 minutes. Wash contaminated clothing before reuse. Get immediate medical advice/attention.
First-aid Measures After Eye Contact: Rinse cautiously with water for at least 60 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Get immediate medical advice/attention.

First-aid Measures After Ingestion: Rinse mouth. Do not induce vomiting. Immediately call a poison center or doctor/physician.

Most Important Symptoms and Effects Both Acute and Delayed

Symptoms/Injuries: Causes severe skin burns and eye damage. May cause respiratory irritation. Skin sensitization. May cause cancer.

Symptoms/Injuries After Skin Contact: Cement may cause dry skin, discomfort, irritation, severe burns, and dermatitis. Exposure of sufficient duration to wet cement, or to dry cement on moist areas of the body, can cause serious, potentially irreversible damage to skin, eye, respiratory and digestive tracts due to chemical (caustic) burns, including third degree burns. A skin exposure may be hazardous even if there is no pain or discomfort. Cement is capable of causing dermatitis by irritation and allergy. Skin affected by dermatitis may include symptoms such as, redness, itching, rash, scaling, and cracking. Irritant dermatitis is caused by the physical properties of cement including alkalinity and abrasion. Allergic contact dermatitis is caused by sensitization to hexavalent chromium (chromate) present in cement. The reaction can range from a mild rash to severe skin ulcers. Persons already sensitized may react to the first contact with cement. Others may develop allergic dermatitis after years of repeated contact with cement.

Symptoms/Injuries After Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of clinker dust, dry cement powder or with wet cement can cause moderate eye irritation, chemical burns and blindness. Eye exposures require immediate first aid and medical attention to prevent significant damage to the eye. Symptoms/Injuries After Ingestion: May cause burns or irritation of the linings of the mouth, throat, and gastrointestinal tract. Chronic Symptoms: May cause cancer.

FIRE-FIGHTING MEASURES

Extinguishing Media
Suitable Extinguishing Media: Use extinguishing media appropriate for surrounding fire.
Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire.

5.2. Special Hazards Arising From the Substance or Mixture
Fire Hazard: Product is not flammable.
Explosion Hazard: Product is not explosive.
Reactivity: Wet cement is alkaline and is incompatible with acids, ammonium salts and aluminum metal. Cement dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride.

5.3. Advice for Firefighters
Precautionary Measures Fire: Exercise caution when fighting any chemical fire.
Firefighting Instructions: Use water spray or fog for cooling exposed containers. Do not get water inside containers. Do not apply water stream directly at source of leak.
Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection. Hazardous Combustion Products: None.

Environmental Considerations:

Modified cement production involves the release of carbon dioxide (CO2) emissions, primarily from the calcination of limestone and combustion of fossil fuels. Use cementitious materials judiciously to lower environmental impact when feasible. Like Nu helps in implementing sustainable practices such as optimizing mix designs, maximizing the use of supplementary cementitious materials, and limiting concrete waste removal.
