Hello Clemmie! ! I apologize for your inconvenience with the tape installation. 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 essential. Additionally, we recommend that you install the Fasade backsplash panels to a smooth, flat surface. Occasionally, even after properly preparing the substrate, the surface can still have bows, high spots, ridges or uneven areas that may cause an issue with the double sided adhesive tape.
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. Please feel free to contact customer care for any further question or troubleshooting tips at 800.434.3750. Thank you!
