Is it possible to get different weights for this paper sheet?
Yes, we offer other weight options such as E-weight and F-weight. We would be happy to discuss those options with you further.
What type of sanding applications can this product be used for?
This product is ideal for use on hardwoods, MDF (medium-density fiberboard), and carbon steel. They are typically used during the rough sanding stages before finishing surfaces up nicely before staining etcetera.
. How long does each Paper Sheet last approximately while using them regularly?
. The overall lifespan will depend on various factors linked to usage patterns and surface materials they are being applied to; unfortunately, there isn't one straight forward answer relating to how long they last when frequently used since that depends highly upon individual user techniques when applying pressure and their technique.
Aluminum oxide is a highly durable mineral that maintains sharp points on the grains for a longer period compared to natural abrasives like emery or garnet. The sandpaper features an open-coat construction where the abrasive grains are attached with some space between them. This design helps minimize the accumulation of dust on the paper's surface, preventing the abrasive points from getting clogged. The issue of loading, which often occurs when sanding soft materials, is effectively addressed by this open-coat construction. By reducing the clogging of the abrasive, the usable life of the sandpaper sheet is extended.
