The first step in refinishing is often the most labor-intensive, requiring the removal of thick paint, heavy rust, or deep burrs. 80 grit sanding sponge uses P80 aluminum oxide to aggressively strip away these layers. The 100 × 70 × 25mm sponge body allows the operator to apply force to flat panels while conforming slightly to edges, preventing the gouging that a rigid block would cause on curved metal or wood.
In furniture restoration, P80 strips thick varnish and paint. In metal fabrication, it removes heavy mill scale and rust before welding or coating. In architectural renovation, it clears peeling paint from old walls and trim. For on-site repairs without power tools, the sponge provides the necessary cutting force by hand.
Post-Strip Preparation
After the heavy stripping, the surface will be rough and covered in deep scratches. It must be smoothed with a P120–P180 medium grit before any finish is applied. Using the P80 sponge dry provides the fastest cut, while dampening it slightly reduces airborne dust during indoor demolition work.
Dongguan Sansha Abrasives Co., Ltd. supplies these coarse sponges in bulk for renovation contractors and hardware distributors. The sponge density is checked against the approved sample to ensure it withstands the high pressure of heavy stripping. Small test batches ship in three days, and large bulk orders take about a week. The transaction requires a 50% deposit, with the final balance cleared after inspection.
