Hello! Thank you for taking the time to review our product. I apologize for any inconvenience or dissatisfaction in our product. One issue you may encounter is caused by oil, grease splatter, drywall dust and fingerprints. We recommend the surface be dirt and grease free before applying the Fasade decorative panels with the double sided adhesive tape. Cleaning is an essential step. Additionally, we recommend that you install the Fasade backsplash panels to a smooth, flat surface. If proper adhesion is difficult or impossible, a recommended adhesive can be applied to the back of the tile to allow good adhesion. We recommend a high-quality polyurethane construction adhesive be applied to the back of each panel in these cases. The recommended adhesive is Loctite® PL Premium for a permanent application. We would be happy to assist you with any questions, concerns, or frustrations that you encountered with your order. We want you to be satisfied with the outcome of your project and enjoy it for years to come. Please contact customer care at 800.434.3750 with any questions so we may help to resolve the trouble you may have experienced with your installation. Thank you
