WANSHIELD®63238 Floor Coating Ultra-Wear-Resistant Polyurethane Topcoats

Product Applications

4. Application Guidelines

Surface Preparation:

1. For all new and old concrete floors: The concrete strength must reach C25 or above. 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.
2. 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.
3. 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.
4. For new concrete floors: Ensure that the floor has passed the curing period and the moisture content is less than 6%. It is crucial to use mobile sandblasting tools and grinding equipment to treat the concrete surface to achieve the correct surface roughness.
5. For other surfaces: If the product is to be used on other substrates, please consult the Technical Department of Yantai Wanhua Energy Conservation and Environmental Protection New Material Co., Ltd.

Concrete strength ≥C25, moisture <6%.

Remove oil/contaminants (sandblasting recommended for new concrete).

Application Conditions:

Coating Process:

1. Mix components per specified ratio

2. Apply via squeegee + cross-roller technique

3. Allow 24h recoat interval at 25°C/60% RH

Note: The drying time is measured under standard conditions (25°C, 60% humidity) and is for reference only. The drying speed varies greatly under different temperatures and humidities, and is also affected by factors such as film thickness, ventilation conditions, and underlying coatings. Generally, the drying time shortens as the temperature rises and lengthens as the temperature drops.

Before formal project construction, the buyer must conduct tests in an environment consistent with the construction conditions to ensure the reliability of the coating system for the specific project. Formal construction is regarded as the buyer’s recognition of the product’s performance inspection. If the above operations are not followed, all responsibilities shall be borne by the buyer.
