## Long description

Proline PROBUILDER sandpaper sheets K40, pack of 5, are coarse abrasive sheets designed for substantial material removal and aggressive surface preparation. These sheets are suitable for both manual sanding and use with compatible sanding blocks or machines. They are intended for rough sanding, shaping, and removing paint, rust or heavy coatings from wood, metal and other solid surfaces prior to further finishing.
Advantages
The coarse K40 grit provides rapid stock removal and effective shaping of uneven surfaces, saving time on initial preparation. Durable abrasive grains and a backing designed for flexibility allow consistent performance during manual use or when mounted on sanding tools. Supplied in a compact 5-piece pack, the sheets are convenient to store and replace during medium- and large-scale jobs.
Suitable for
Rapid removal of old paint and rust from metal surfaces
Shaping and leveling rough timber before fine sanding
Preparing surfaces for welding, priming or repainting
Heavy sanding of solid workpieces and rough carpentry tasks
Key specifications
Grit: coarse (K40) for aggressive material removal
Quantity: 5 sheets per pack
Compatibility: for hand sanding and use with standard sanding blocks or compatible sanding machines
Suitable substrates: wood, metal and other solid surfaces
How to use
Select the K40 sandpaper sheet and secure it to a suitable sanding block or machine pad, or hold it firmly for manual sanding. Work with even pressure and follow the grain on wood where applicable to avoid deep scratches. For metal surfaces, move the sheet consistently across the area to remove paint or rust, checking progress frequently to avoid excessive material removal. Replace the sheet when abrasive performance declines or the backing becomes compromised.
Usage recommendations
Use proper personal protective equipment such as gloves, eye protection and a dust mask when sanding. Begin with K40 for heavy removal and switch to finer grits as you approach the desired surface smoothness. Avoid applying excessive heat or pressure that could clog the abrasive or damage the workpiece.
