Colored - Sand Water - based Polyurethane Mortar Flooring System

1. Product Overview

WANSHIELD®63122 Colored Quartz Polyurethane Mortar is a four-component, waterborne self-leveling flooring system combining the advantages of organic polymers and inorganic materials with decorative aesthetics. It is mainly developed as a 4 – 6 – millimeter medium – load – bearing polyurethane mortar self – leveling floor for applications that demand chemical resistance, rich appearance, beauty, and durability. It is suitable for load – bearing self – leveling floors and has characteristics such as stain resistance, no delamination, compression resistance, wear resistance, corrosion resistance, and temperature resistance.

Key Features:

Chemical resistance (acids, alkalis, solvents).

Decorative versatility (customizable colors/patterns).

Durability (compressive strength ≥40MPa). Its tensile strength exceeds that of ordinary concrete, providing enhanced structural stability.

Compared to cement – based products, it has higher toughness. This property effectively reduces the risk of cracking.

Wide – Range Temperature Adaptability: -20°C to +75°C
Vicat softening point ≥140°C
Abrasion resistance ≤0.15g/100r
Slip resistance (dry COF ≥0.6)

Applications

In food processing factories, dairies, breweries, and distillation workshops, where the floor needs to withstand the impact of food production processes, including exposure to various ingredients, cleaning agents, and changes in temperature and humidity.
In pharmaceutical intermediate production workshops and laboratories, where a clean, durable, and chemically resistant floor is required to meet strict hygiene and safety standards.
In both wet and dry processing areas, as well as refrigerated and frozen zones, due to its ability to adapt to different temperature and humidity conditions and its resistance to water and cold.
In chemical processing plants, pulp and paper mills, large – scale clean warehouses, and storage areas, where the floor is constantly exposed to chemicals, heavy loads, and the need for easy cleaning and maintenance.

3. Application Guidelines

Surface Treatment Before Construction

Concrete substrate ≥C25 with ≥1.5MPa pull-off strength
Moisture content <10%
Surface profile: ICRI CSP 3 (50-100μm) via mechanical abrasion

For All New and Old Concrete Floors: The concrete strength must reach C25 or above, and the pull-out strength should not be lower than 1.5MPa. Thoroughly remove surface stains and loose soil until reaching the solid concrete layer. For any concrete damaged, loosened, or contaminated by substances due to exposure to chemicals, it should be removed until the solid concrete is exposed.
For Painted Old Floors: Completely sand off the loose or incompatible old paint coatings. If the underlying concrete surface or a clean, dry, and intact compatible coating is exposed, it can be left without further removal.
For Oil-Stained Floors: When the oil stains seriously affect the adhesion of the floor coating to the base surface, the oil-stained floors should be thoroughly cleaned and sanded.
For New Concrete Floors: Ensure that the floor has passed the curing period and the moisture content is less than 10%. It is crucial to use mobile sandblasting tools and grinding equipment to treat the concrete surface to achieve the appropriate surface roughness.
For other surfaces: If the product is to be used on other substrates, please consult the Technical Department of Yantai Wanhua.
For detailed instructions on base surface treatment, please consult us to obtain relevant materials.

Construction Conditions
Coating Environment Temperature: 15 – 30°C. The base surface temperature should be at least 3°C higher than the air dew-point temperature.
Coating Environment Humidity: <80%, and the moisture content of the concrete base surface should be less than 10%.
Ventilation Conditions: Ensure that the construction site is well-ventilated and dust-free. However, there should be no strong wind to avoid bringing in dust and affecting the appearance.

Mixing Methods:

Step	Components	Ratio	Mixing Parameters
1	A+B+D	5.48:5.71:var	300rpm/1min @>35°C
2	Add C	20 parts	800rpm/2min @15-35°C

After determining the stirring time, it should be kept consistent throughout the construction process. Inconsistent stirring time for each group may cause differences in surface color and texture.

During the mixing process, use a straight-edge trowel to scrape the raw materials adhering to the sides and bottom of the container. This operation should be carried out at least once to ensure complete mixing.
Only the raw materials in the factory-packed containers need to be fully mixed. Temperature will affect the construction time and product curing time.
Different mixing machines may lead to differences in fluidity. It is recommended to use the recommended mixing head for mixing.

Primer Coating

After applying the primer coating, allow it to dry for 24 hours (when the ground temperature is 20°C; the lower the temperature, the longer the curing time). Then, proceed with the surface coating construction.
If the primer coating has been applied for more than 72 hours or is contaminated, it is necessary to sand and vacuum the surface again before constructing the surface coating.

Surface Coating

Apply the coating to the required thickness with a trowel or squeegee. To ensure the flatness of the surface layer, the amount of coating used should be kept above 4 kg/m². In the early stage of spreading, the fluidity is low, but it will gradually level out through defoaming operations to achieve a flat surface.

Installation:

Base coat: 1mm (0.9kg/m²), cure 24h @20°C
Top coat: 3-5mm (6-10kg/m²), trowel-applied
Walkability: 24h, full cure 7 days

4. Packaging & Storage

Component	Package	Qty	Shelf Life
A	Plastic pail	5.48kg	6 months
B	Plastic pail	5.71kg	6 months
C	Composite bag	20kg	6 months
D	Pouched	0.2-1kg	6 months

Storage: 5-30°C in dry, ventilated area.

Storage and Transportation Conditions: The paint should be stored in a sealed, dry, cool, and well-ventilated environment at 5 – 30°C, away from high temperatures and fire sources. During transportation, the materials should be stacked steadily, and the carriage environment should be kept dry, enclosed, and protected from moisture and frost.
Shelf Life: Starting from the production date, under the required storage conditions, the shelf life of the product in its original packaging is 6 months.

5. Safety & Compliance

Before use, carefully read the construction instructions and warning labels on the packaging container. When constructing, wear a gas mask and other protective equipment. Avoid inhaling paint mist and skin contact with the paint.

PPE Requirements:

NIOSH-approved respirator
Chemical goggles + nitrile gloves

First Aid:

Skin: Soap/water → seek medical help if irritation persists.
Eyes: 15-min flush → immediate ophthalmologist visit.

Fire Rating:

This product is not classified as a flammable liquid, explosive, oxidizer, corrosive, toxicant, or radioactive hazardous material during storage and transportation, and is not a hazardous product.

NFPA 704: 0-1-0
Extinguishing: CO₂/dry chemical
In the absence of other fire-fighting agents, a large amount of fog-like water can also be used for spraying. After the fire is extinguished, the spilled materials should be cleaned up (refer to the leakage and spillage treatment section).

Leakage and Spillage Treatment

For a small amount of leakage or spillage, the materials can be washed away with water. In case of a large-scale leak, collect and recycle the materials, and wash the contaminated ground with water or detergents. The disposal of waste compounds must comply with local government environmental regulations.
