Peeling is caused by one of a few things.
For Dura-Rubber, peeling can occur due to specific factors related to its application and environment. Here are some potential causes for peeling with Dura-Rubber:
1. Improper Surface Preparation
• Dirt, Grease, or Oils: Make sure the surface is thoroughly cleaned of dirt, oils, grease, or any other contaminants before applying Dura-Rubber. These can prevent the coating from bonding properly.
• Roughing Up the Surface: For optimal adhesion, the surface should be roughened or sanded if it’s too smooth. This helps create a better surface for Dura-Rubber to grip onto.
2. Moisture or Humidity
• Moisture Content: Dura-Rubber needs to be applied to a dry surface. If there’s any moisture (either in the substrate or in the air), it can interfere with the coating’s bond and cause it to peel. Make sure the surface is completely dry before applying.
• Moisture Underneath: If moisture is trapped beneath the coating (for example, due to improper drying time or water vapor from the substrate), it can cause bubbling or peeling. Ensure proper ventilation and curing time for the coating.
3. Application in Inappropriate Conditions
• Temperature: Dura-Rubber should be applied within the specified temperature range (usually between 50°F and 90°F). Too high or too low temperatures can affect how well the product bonds to the surface.
• Wet Surfaces: Avoid applying Dura-Rubber when it’s raining or there’s high humidity in the air, as this can prevent the coating from curing properly.
4. Curing Issues
• Not Enough Curing Time: If the coating hasn’t had enough time to fully cure before exposure to the elements, it can peel off. Make sure you follow the recommended drying and curing times as specified by the manufacturer.
• Too Thick a Layer: If the Dura-Rubber is applied too thickly, it may not cure properly in the inner layers, leading to peeling. Follow the recommended application thickness.
5. Incompatible Surfaces
• Surface Material: Ensure that the substrate (such as concrete, wood, or metal) is compatible with Dura-Rubber. Certain materials may need a primer or additional preparation before the coating adheres correctly.
• Previously Coated Surfaces: If the surface was previously coated with another material, you’ll need to ensure that Dura-Rubber is compatible with that coating. In some cases, you may need to remove the old coating completely to prevent issues.
6. Contamination or Improper Mixing
• Unmixed Components: If you’re using a two-part Dura-Rubber system, make sure both parts are mixed thoroughly before application. Improper mixing can cause curing issues and lead to peeling.
• Contaminants in the Mix: Ensure that no foreign materials (like dust or dirt) get into the coating while mixing or applying it.
If you’re noticing peeling with Dura-Rubber, I would recommend inspecting the surface preparation, environmental conditions, and curing times to pinpoint the issue. Would you like more specific troubleshooting steps or help with the application process?
