Efficient Cutting on Joint Compound and Paint

Wall sanding requires fast material removal to prevent surface fuzzing caused by excessive rubbing. Sanding discs for drywall use silicon carbide grain (aluminum oxide is also available) in grits from P80 to P220. Diameters include 125mm, 150mm, and 225mm, with a multi-hole configuration for dust extraction.

Applications in Construction and Renovation

These discs level skimmed joint compound and remove nibs and brush marks between latex coats. They shape and blend gypsum board seams along tape and compound. For renovation, they strip loose old paint and flaking filler. On ceilings, the flexible backing follows minor undulations, preventing grooves along the seams when used with pole sanders.

Selecting Diameter and Hole Patterns

The 225mm disc covers wall area quickly for broad leveling, while 125mm and 150mm sizes suit corners, edges, and patch repairs. Both long-reach dust-extraction sanders and hand-held units can use these discs, with hole patterns matched to the machine's extraction layout.

Supply and Payment Terms

Grit, diameter, and hole pattern can be quoted based on your equipment. Samples are provided for approval before bulk production. Small orders ship in about three days; larger orders take roughly one week. Terms are 50% deposit, with the balance paid after inspection and before shipment.
