How to use
For maximum adhesion, durability, and performance, follow these essential steps when applying GMAX Polyurethane Foam Sealant:
1. Clean the Surface 🧼
✔ Ensure the application surface is free of grease, dust, and debris.
✔ A clean surface enhances bonding strength and ensures a long-lasting seal.
2. Prepare the Foam 🔄
✔ Shake the polyurethane sealant spray foam for 1 minute or at least 20 times.
✔ This step is crucial to ensure proper mixing and foam quality.
3. Moisten the Surface 💧
✔ Lightly spray the surface with water before application.
✔ Moisture improves adhesion and enhances foam expansion.
4. Apply the Foam Evenly 🎯
✔ Spray slowly and consistently to maintain the correct polyurethane-to-gas ratio.
✔ Avoid spraying too quickly to prevent improper expansion and adhesion.
5. Allow to Dry & Trim Excess ✂
✔ Let the foam fully cure before making adjustments.
✔ Use a cutter to trim any excess foam for a neat, professional finish.
6. Finishing Touches 🎨
✔ Once dry, the foam can be sanded or painted for a smooth and polished look.
By following these steps, you ensure high efficiency, superior insulation, and long-term durability when using GMAX Polyurethane Foam Sealant in all your sealing and insulation projects.
