Water-based Epoxy Colored Sand Floor Paint Seasonal Application Guide: Avoid pitfalls in winter and summer, increase efficiency in spring and autumn

1. Spring Application (March-May): Moderate humidity, focus on preventing "rebound"

 Optimal application conditions: Temperature 15-25°C, humidity 40%-60% (measured with a hygrometer), avoid the "return of the south wind" (weather when water droplets form on walls and floors).

 Key Points:

 Close doors and windows before application, and use a dehumidifier to reduce indoor humidity (apply to humidity ≤ 60%) to prevent moisture from returning to the base layer, which can cause blistering later.

 After applying primer and topcoat, maintain ventilation (but avoid strong winds to prevent rapid drying and cracking). Allow each coat to dry for 12-24 hours.

 Advantages: Optimal temperature and humidity ensure uniform curing of the material, minimize color variation, and allow for normal use within 7 days of application.

 2. Summer Construction (June-August): High temperature and high humidity, especially preventing bubbling and color shift

 Optimal construction time: 9-11 AM and 4-6 PM (avoid midday heat), with temperatures ≤30°C and humidity ≤70%.

 Key Points:

 Mix materials as needed. Use the colored sand and hardener within 1 hour of mixing (high temperatures accelerate curing, and excessive use can cause lumps and render the paint unusable).

 Apply thinly in multiple coats (each coat ≤0.5mm thick) to avoid thick coats that slow internal curing and wrinkles. If the temperature exceeds 30°C, dilute the paint with 5%-10% water (as directed in the product instructions) to extend its usable life.

 Keep the paint out of direct sunlight (use curtains to block out the heat) to prevent uneven drying times in different areas and color shifts.

 3. Autumn Construction (September-November): Suitable Temperatures, Focus on Preventing Over-Drying

Optimal construction conditions: Temperatures of 10-20°C and humidity of 30%-50%, making this the most suitable season of the year.

Key Points:

Maintain a moderate indoor humidity. If the air is too dry (humidity <30%), place a basin of water around the floor to prevent the coating from drying too quickly and causing cracks.

Close doors and windows within 24 hours after application to allow the coating to cure slowly. After 24 hours, gradually open windows for ventilation to improve adhesion.

Advantages: Uniform curing speed, high surface smoothness, and minimal potential for later problems.

4. Winter Construction (December-February): Low-temperature drying, focus on preventing slow curing and cracking

Optimal construction conditions: Temperature ≥10°C (work should be stopped if it falls below 10°C). Air conditioning or heating can be used to increase the temperature (but avoid allowing localized floor temperatures to exceed 20°C to prevent significant temperature fluctuations). Key Points:

Preheat the materials indoors for 24 hours before application (to avoid materials that are too cold and slow to cure after mixing). Increase the curing agent in the colored sand/curing agent mix (up to 10% according to the product instructions) to accelerate curing.

Extend the drying time to 24-48 hours per coat to avoid delamination caused by applying the next coat before it is completely dry. After application, close doors and windows and use heating to maintain a room temperature of ≥15°C for 7 days to ensure complete curing.

Avoid opening windows immediately after application (low outdoor temperatures can cause the floor to cool rapidly, leading to cracking). Open windows gradually for ventilation after 7 days.
