1. What is SPO Glass Shading Heat Reduction Paint used for?

SPO Glass Shading Heat Reduction Paint is a water-based coating designed to lower interior temperatures in greenhouses, factories, and other glass structures. It filters out excessive sunlight, helping maintain cooler conditions.

2. How does it reduce heat buildup?

The paint’s reflective properties help deflect intense sunlight, preventing the interior from overheating. This keeps plants, equipment, and occupants safer and more comfortable, potentially reducing cooling costs.

3. Is it suitable for different types of transparent surfaces?

Yes. This paint adheres to glass, acrylic, polycarbonate, and various other transparent materials, offering broad usage possibilities in different environments.

4. How do I apply the paint?

You can mix the paste to your desired dilution ratio, then apply using a brush or a short pile roller. Ensure the surface is clean and dry before painting. A thin, even coat helps achieve optimal results.

5. How long does it take to dry?

Typically, the paint is touch-dry within 1–2 hours, depending on temperature and humidity. This quick drying time means you can re-coat or make adjustments sooner, minimising project downtime.

6. Will this paint block too much light for greenhouse plants?

You can customise the dilution to balance heat reduction with adequate light transmission for plant growth. Start with a lighter application and adjust coverage based on your specific shading requirements.

7. How long does the heat-reducing effect last?

When applied correctly, the paint provides a long-lasting, cooling barrier throughout the hot season. Reapply as needed if you notice diminished effectiveness over time or after heavy weather exposure.
