Precision Refinement: SiaSpeed 1950 6-Inch PSA Sanding Discs

Optimized Intermediate Finishing with SiaSpeed Technology

When your project moves from heavy shaping to precision refinement, the SiaSpeed 1950 6-inch 150-grit sanding disc provides the perfect balance of stock removal and surface uniformity. Engineered with high-performance semi-friable aluminum oxide, these discs are designed to deliver a consistent scratch pattern that serves as the ideal foundation for final primers and topcoats.

Designed for professionals in automotive refinishing, cabinetry, and metal fabrication, the 150-grit series is a versatile workhorse. The Pressure Sensitive Adhesive (PSA) backing ensures a perfectly flat, secure bond to your backup pad, while the integrated multi-hole pattern provides industry-leading dust extraction—keeping your surface visible and your lungs protected.

Rapid Flatting and Clog-Resistant Performance

The 150-grit SiaSpeed 1950 is specifically tuned for intermediate “flatting” tasks where accuracy is paramount. Whether you are leveling body filler or smoothing out composite repairs, this disc is built to work efficiently without the frustration of premature loading.

Key features that drive productivity include:

  • Electrostatic Open Coating: Strategically spaces the abrasive grains to allow dust to escape, significantly extending the life of the disc.

  • Specialized Stearate Layer: An advanced anti-clogging treatment that prevents “pilling,” especially when sanding “soft” materials like fresh primer or resin.

  • FSC-Certified Paper Backing: A robust, environmentally conscious foundation that provides the necessary stiffness for flatting edges and transitions without tearing.

Application:

  • Sanding of coatings and impurities
  • Sanding out unevenness at the edges of repaired surfaces
  • Flatting of body filler and composite materials
  • Fine sanding of primer filler
  • Keying of old and new lacquers
  • Producing a matt finish on old and new lacquers for blending
