Can I use poster putty on textured walls?

Yes, and putty is actually the better choice on textured walls. It molds into the bumps and grooves that keep flat adhesive strips from making full contact, which gives it a stronger hold on surfaces like orange peel or knockdown texture.

• Roll and press: warm a small ball between your fingers, then press it into the wall texture.
• Use the corners: a dab at each corner and midpoint keeps the poster flat.
• Keep it lightweight: putty is meant for paper posters, not heavy or mounted prints.

For anything mounted on foam board or a heavier substrate, use a frame or hook instead, since putty cannot support that weight on any surface.
