💧 Why Water Matters When Applying PU Foam

Do you really need to spray polyurethane foam with water? Yes — and in this video, we explain exactly why. When working with one-component PU foam, water is not optional. It’s a key part of the curing process. Without proper moisture, foam cannot achieve its full mechanical strength, insulation performance or long-term durability. 🔬 What happens without water? One-component polyurethane foam cures through a chemical reaction with moisture. If the surface is not properly sprayed (at temperatures above 0°C): The foam structure may become irregular Air voids can form inside the joint Insulation properties decrease Mechanical strength may be reduced The risk of secondary expansion increases That’s why professional contractors always use a fine water mist before and after application. 🛠 Pro Tip from the Job Site 💡Use a garden sprayer that creates a fine mist 💡Spray the surface lightly before application 💡Spray again after each layer 💡Apply foam in layers for deeper joints 💡Always follow manufacturer guidelines Small detail. Big difference! Proper water spraying means better structure, better insulation and long-term performance.
