Product Information
Full details
The Prep Plastic Sanding Block 551 is an essential tool for DIY enthusiasts and professionals seeking a perfectly flat finish on various materials. Its primary benefit lies in its ergonomic design and secure sandpaper retention system, which ensures consistent pressure across flat surfaces while maintaining flexibility for contoured areas. Users should note that while it provides excellent control, it requires specific sandpaper sizing, meaning you must cut standard sheets into smaller strips before application.

FAQs
Can I use this for wet sanding?
Yes, the Prep Plastic Sanding Block is designed to handle both wet and dry sanding tasks without damaging the tool.
How should I cut my sandpaper?
Cut a standard 9x11 inch sheet into four equal-sized strips to fit the dimensions of the block.
Is the sanding block flexible?
It is rigid enough to maintain a flat surface but designed with materials that allow it to conform to gentle curves and body contours.
How do I secure the paper?
Lift the top of the block, place the paper over the spikes, and press the top down until it locks.
What surfaces is this best for?
It is ideal for wood, automotive bodywork, drywall, and general surface preparation tasks.
Troubleshooting
Sandpaper keeps slipping during use
Ensure the sandpaper is pushed fully onto the metal spikes and that the top cover is snapped into the locked position.
The sandpaper is tearing
Reduce the amount of downward pressure applied; use a steady back-and-forth motion rather than aggressive pushing.
Metal spikes have become clogged with debris
Use a stiff-bristled brush or compressed air to clear the area around the spikes to ensure a tight grip on the next sheet.

- Ergonomic handle reduces user fatigue

Setup, Compatibility & Care
To prepare your block for use, take a standard 9-inch by 11-inch sandpaper sheet and cut it into four equal strips. Open the block by lifting the top cover, which exposes the integrated metal spikes. Align your sandpaper strip over these spikes and push the cover back down firmly; the spikes will penetrate the paper and lock it into the chassis.
After each use, tap the block to remove loose dust. If you were performing wet sanding, rinse the block under clean water and pat it dry with a shop towel. Store the block in a cool, dry environment to keep the plastic casing and internal spikes in optimal condition.
