The surface should be smooth and flat as possible. A slight texture may not affect the adherence , we do encourage you to give It a try.
Since these are Wall Planks made of wood, this will not stick to brick. I would apply this by itself.
Thank You for choosing Roommates! This wall plank is a peel & stick. You can simply remove the adhesive backing and stick where desired. They're also easy to cut if needed with any type of sharp knife, no saw needed. Thank You
It is recommended, if possible, to remove wallpaper before installation.
