What types of surfaces are unsuitable for adhesive mounting?

Surface Preparation

When installing solar flexible panels, it’s crucial to ensure the surface is suitable for adhesive mounting. A poorly prepared surface can lead to a weak bond, compromising the integrity of the installation. Avoid using adhesive on surfaces with high moisture content, such as damp wood or concrete. For wooden surfaces, lightly sand them to create a rough texture, allowing the adhesive to grip better. Use a clean, dry cloth to wipe away dust and debris.

Types of Unsuitable Surfaces

Porous materials like brick, stucco, or rough-finished concrete are not ideal for adhesive mounting. These surfaces provide too many gaps for the adhesive to seep into, reducing its effectiveness. Additionally, surfaces with oil or grease residues, such as old paint or varnish, can prevent the adhesive from bonding properly. In such cases, use a surface cleaner or degreaser to remove the contaminants before applying the adhesive.

Surface Stabilization

To ensure a stable surface for adhesive mounting, consider using a surface stabilizer or primer. These products create a strong bond between the surface and the adhesive, preventing slippage or movement over time. For example, on a metal roof, use a metal primer to create a strong bond between the adhesive and the roof surface. This will help prevent the solar panel from shifting or detaching due to wind or weather conditions. Always follow the manufacturer’s instructions for the specific adhesive and surface stabilizer being used.
