Classroom teachers across the country are often faced with decorating restrictions due to fire codes and school rules. For years they have also tried to figure out how to get their posters and signs to stick to the cinder block walls in the classroom.
The following tips should work, individually or in-combination, for just about any wall. Try them out and your classroom will be decorated in no time!
Tip #1: Hot Glue Gun
A low-temperature hot glue gun is a great tool for getting posters, banners, trimmers, and more to stick to the cinder block classroom walls. At the end of the year, the glue pulls off easily from the wall and does not do any damage.* Always use caution and only use the hot glue gun when students are gone for the day. Make sure to unplug it after use!
*If the paint on your classroom walls is old and flaking, there is a chance that the glue could peel some of the paint off when it is removed. Test in a small, inconspicuous spot before decorating the whole classroom!
Tip #2: Sticky or Blu Tack
Remember that blue, sticky putty that you saw fleetingly during teacher training? That was Sticky or Blu Tack. It is a reusable, synthetic rubber compound that can be stretched and manipulated to just the shape you need. While it traditionally comes in blue, the blue coloring can leave a bit of a residue (especially if you use a generic brand) so you may want to try the white depending on the color of your classroom.
Tip #3: Stikki-Clips
Stikki-Clips were specially designed to adhere to any surface – including cinder block and brick walls! They make switching out anchor charts and students’ work throughout the year a breeze. The unique adhesive is even good for painted surfaces and the clips can be re-used again and again.
Tip #4: Display Strips
Self-sticking display strips like “Cling Thing Display Strips” are removable strips that adhere to walls, doors, metal, plastic, cinder block walls, and more. They allow you to display posters, anchor charts, student work, alphabet and number lines, and more. Some of them can even “re-gain” their stickiness with a light spritz of water! At the end of the year, they peel off without damaging the paint or surface behind them.
