WANSHIELD®62238 Solvent-Free Epoxy Self-Leveling Topcoat for Floor Coating

Physical & Chemical Properties

*Includes water (168h), oil (120# solvent, 72h), alkali (20% NaOH, 72h), acid (10% H₂SO₄, 48h).
Note: Data are typical values; actual performance may vary with conditions. Specifications are non-binding.

Construction Requirements

• Concrete strength ≥C25; the flatness should meet the requirement of a 2m alignment ruler with an error within 3mm.
• 28-day curing period required before application to achieve the best results.
• Ambient temperature: 5–35°C (avoid application below 5°C). as it may affect the project quality and the strength of the cured paint film.
• Substrate moisture ≤5%; ambient humidity ≤80%. Otherwise, problems such as blistering may occur, affecting the appearance.
• Ensure dust-free and ventilated environment (avoid strong airflow).

2. Surface Treatment:

• Grind the substrate to remove contaminants, loose layers, and create a rough surface for enhanced adhesion.

3. Primer Application:

• Use WANSHIELD®62201 Solvent-Free Epoxy Primer or WANSHIELD®62305 Universal Epoxy Primer.

• Apply via trowel or roller (0.15–0.25 kg/m²).

• Ensure no missed coating areas and avoid over – coating. If necessary, apply a second coat of primer or repair the missed coating areas.

4. Intermediate Layers:

• Mortar: Mix WANSHIELD®62208 (A:B) with 80–120 mesh quartz sand; trowel-apply.
• Putty: Mix WANSHIELD®62208 (A:B) with quartz powder; fill voids and level.

5. Topcoat Application:

• Mix WANSHIELD®62238 (A:B=5:1) thoroughly; pour and spread with notched trowel.

• Use spiked roller to eliminate bubbles and enhance leveling.

Construction Parameters

• Mixing ratio (by weight): A:B = 5:1. use a high – speed mixer to stir thoroughly.

• Pot life (25°C): 1.5 hours after mixing (1 hour after pouring). The higher the temperature, the shorter the pot life. Construction is generally not recommended when the ambient temperature during construction is higher than 35°C.

• Diluent: Not allowed.

• Recoat interval: The next construction process can be carried out only after confirming that the coating is completely dry. Usually, 24 hours under standard conditions (25°C, 60% humidity).

Note: Drying time varies with temperature, humidity, film thickness, and ventilation. Higher temperatures shorten drying time.

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.
