A Meeting Room Whiteboard on a Roll

Post-it DEF4X3 is a 3 ft x 4 ft roll of Super Sticky dry erase surface, which 3M list as 91.4 cm x 1.21 m, enough to turn a meeting room wall, a classroom panel or a table top into a whiteboard.

This is the middle size of the range and the one most often chosen to replace a tired wall board. 3M suggest resurfacing old whiteboards or chalkboards with it, creating horizontal work spaces on tables and desks, or going bigger and covering a wall.

3M describe the material as stain-proof and say it erases cleanly every time. Their pack tiles add that it is easy to install with no tools required, and that it sticks securely and removes cleanly. The range is made to stick to painted drywall and steel, glass, finished wood and existing boards, and the sheet can be cut to fit.

Our title rounds the size to 1200 x 900 mm; measure your space against 3M's figure of 91.4 cm x 1.21 m before you cut.

Finish the setup with whiteboard markers and cleaners, or compare whiteboards and dry erase products.
