Common Mistakes to Avoid When Using Polyurethane Sealants
Polyurethane sealants are versatile products that offer excellent adhesion, flexibility, and durability. However, even experienced professionals can make mistakes when using these sealants. To ensure optimal performance and longevity, it's crucial to avoid these common pitfalls. 1. Improper Surface Preparation: One of the most common mistakes is neglecting proper surface preparation. Surfaces must be clean, dry, and free of contaminants like oil, grease, and loose paint. Failure to adequately prepare the surface can lead to poor adhesion and premature sealant failure. 2. Incorrect Application Temperature: Polyurethane sealants are sensitive to temperature. Applying them in extreme cold or heat can affect their curing time and final properties. It's essential to follow the manufacturer's recommended temperature range for optimal performance. 3. Over-Application: Applying too much sealant can lead to excessive curing time, poor adhesion, and unsightly excess material. It...
