Yes, you need to prep a painted wall before tiling. Start by cleaning the surface thoroughly to remove any grease or dirt. Lightly sand the wall to create a rough texture, ensuring better tile adhesion. Repair any cracks or holes and apply a primer suitable for the adhesive you’ll be using. Taking these steps will provide a more durable and long-lasting tile installation.

Questions and answers

Do I need to remove paint before tiling a wall?
You don't necessarily need to remove all the paint, but the surface should be cleaned, lightly sanded, and primed to improve tile adhesion and durability.
What kind of primer should I use on a painted wall before tiling?
Use a primer that is compatible with the tile adhesive you plan to use; this helps create a better bond between the paint and the tiles.
Can I tile directly over a glossy painted wall?
No. Glossy surfaces should be sanded to a dull finish to create a rough texture that helps tiles stick more securely.
