Key benefits of using P40 sandpaper
When choosing an abrasive material, efficiency and durability are key. Our P40 grit sandpaper offers a number of advantages that will make your work easier and improve the final result:

Extra coarseness (P40): The perfect choice for quickly and effectively removing old paint, varnish, rust and for rough shaping wood and other surfaces. The P40 grit allows for aggressive material removal with minimal effort.
Premium abrasive material: Aluminum oxide provides a high level of hardness, sharp edges and long-lasting work surface without rapid wear. This means fewer paper changes during work.
Completely waterproof: The paper does not soften or disintegrate during wet sanding. Wet sanding effectively reduces the amount of dust in the air, cools the surface being sanded and extends the life of the paper.
Standard dimension 230 x 280 mm: Universal size that can be easily cut or folded for hand sanding, or mounted on orbital sanders and sanding blocks.
Incredible quality-price ratio: As part of a special PROMOTION, you will receive top-quality professional abrasive material at an extremely affordable price of only EUR 0.29 per piece.

Versatile use in the workshop and in the field
P40 sandpaper is indispensable for preparing surfaces for further processing. Due to its coarse structure and durability made of aluminum oxide, it is excellent for a wide range of tasks in the home workshop, car painting practice or on the construction site:
1. Rough woodworking
It is ideal for smoothing rough wooden surfaces, removing splinters, leveling unevenness and preparing wooden beams, planks or old wooden floors for further fine sanding and finishing. The coarse granulation quickly removes surface irregularities and prepares the wood for the application of impregnation or primer.
2. Removing paint, varnish and rust
Whether you are restoring old furniture, metal railings, radiators or vehicle parts, the P40 grit will quickly and effortlessly remove stubborn layers of old paint, varnish and corrosion. The aluminium oxide penetrates deep into the layers of rust and effectively removes them down to the bare metal, ensuring excellent adhesion of new protective coatings.
3. Car painting and putty sanding
Due to its waterproof properties, this paper is extremely popular in the automotive industry. It allows for precise wet sanding of automotive fillers and fillers, which prevents the raising of fine dust, reduces material heating and provides better control over the treated surface. This will allow you to achieve perfectly straight lines before applying subsequent layers.
Why choose alumina?
Aluminum oxide is one of the most popular and effective abrasive materials on the market, used in the professional industry. It is characterized by a high level of toughness and the ability to self-sharpen during the sanding process. When the particles wear down during the work, they break down under pressure and create new, sharp edges. This means that P40 sandpaper maintains its cutting power significantly longer than conventional sandpapers, saving you time and money by using less material to complete the same project.
Frequently Asked Questions (FAQ)
For which materials is P40 sandpaper suitable?
P40 aluminum oxide sandpaper is extremely versatile. It was developed for roughing wood, metal, plastic, painted and varnished surfaces, fillers and automotive putty. Due to the high hardness of the abrasive grains, it is also suitable for harder materials where rapid removal of surface layers is required.
What is the advantage of waterproof sandpaper?
Waterproof sandpaper enables wet sanding using water or special lubricants. Wet sanding offers several key advantages: it prevents the paper from clogging with particles of sanded material, drastically reduces dust in the work area, cools the treated surface and enables smoother and more even processing without deep, unwanted scratches.
Can I use this sandpaper on electric sanders?
Yes, the standard size of 230 x 280 mm can be easily cut into suitable formats (e.g. in half or thirds) and clamped into hand sanding blocks or orbital sanders that support mechanical clamping of the paper with clamps. Due to the durable backing, the paper will not tear during machine operation.
