Hi @zangsf1! Thank you for your interest in Abolos peel and stick mirror tiles. To answer your question, these backsplash tiles are made as DIY tiles, they are a simple and easy peel-and-stick installation.

Things to watch out for during installation:
*Abolos peel and stick tiles can be installed over most structurally sound substrates if they are clean, smooth, dry, and free of dust, wax, soap scum and grease such as hardiebacker or drywall.
*Please note this tile cannot be used in a water submerged environment, such as a pool or shower backsplash.
*Tiles can be cut using a score and snap cutter.

Hope that helps and happy shopping! -Abolos
