Whiteboard Post-It 3M FWS4X3 fixed 1220 x 914 mm, white surface

Post-It 3M FWS4X3 fixed 1220 x 914 mm is a permanently mounted writeable surface with a white finish designed for wall installation. The 1220 x 914 mm working area provides a medium-sized board suitable for offices, classrooms, meeting rooms and planning spaces. The white surface accepts both dry-erase and permanent markers and is engineered for easy cleaning: dry-erase ink wipes away with a cloth while permanent marker can be removed with water and a cloth. The flexible material adheres securely to smooth vertical surfaces and can convert walls or large panels into continuous writing areas without the bulk of a framed board.

Advantages

The Post-It Flex Write Surface combines versatility and simplicity: it works with dry-erase markers for temporary notes and with permanent markers when a lasting mark is required, and both types are removable with simple cleaning methods. Installation is straightforward — unroll, peel, and stick — allowing rapid conversion of existing walls or tables into functional whiteboard space. The material is designed to stick securely while removing without damage, providing a durable, low-maintenance solution for collaborative environments.

• Office meeting rooms and huddle spaces for planning and presentations
• Classrooms and training rooms for teaching, diagrams and group work
• Project planning areas, Kanban walls and visual management boards

How to use

Prepare a clean, smooth, dry vertical surface. Measure and position the Post-It Flex Write Surface to align with the desired area. Unroll the product, peel back the adhesive liner progressively and press the surface firmly against the wall to remove air bubbles. Use dry-erase markers for temporary notes and brainstorming; erase with a dry cloth or eraser. For important or long-term markings, use permanent markers and remove them later with water and a cloth as needed. If small areas need repositioning during installation, lift gently and reapply while maintaining surface cleanliness.

Usage recommendations

The white surface performs best on clean, smooth walls or panels; avoid textured or heavily painted surfaces for optimal adhesion and removability. When using permanent markers, test a small inconspicuous area first and remove with water promptly to minimize staining. For large installations, work with a second person to ensure even application and to avoid trapped air. Store unused portions rolled and protected from dust and extreme temperatures.
