Prepare the wall surface
Make sure the wall is:
- Clean
- Dry
- Flat and stable
Suitable surfaces include:
- Tiles (smooth and slightly textured)
- Painted walls (except latex paint)
- Plaster & drywall (only with a primer/undercoat)
- Glass / acrylic glass
- Plastic, metal, and other smooth surfaces
Ensure the surface is clean, dry, and free from dust, grease, and oil before application.
