Scotch Brite and abrasive sponge

Sponge & Abrasive Roller

To clean and prepare surfaces before sanding, use:

• Fragile plastics: degrease with isopropyl alcohol, then rub with an abrasive sponge.
• Resistant plastics (PD, PP, PEHD): soak the sponge in thinner and rub the part.

Choosing the right sanding sponge

Several criteria determine your choice:

• Type of grit:
  • Fine grit (150–240) for precise finishes.
  • Medium grit (60–80) for quick and effective sanding.
  • Coarse grit (24–50) for stripping and rough sanding.
• Flexibility: a soft sponge conforms to curved surfaces, ensuring even sanding.
• Durability: for intensive use, choose a durable sponge that will last longer.
• Material to work on: choose according to the substrate (wood, metal, plastic).

Available grit sizes

• 24 – 50: stripping, rough sanding
• 60 – 80: quick sanding
• 100 – 120: finishing roughing
• 150 – 240: precise finishing
• 320 – 600: very fine finishing
• 800 – 1200: removal of lacquers and paints

Surfaces of use

• Wood: restoration, smoothing, preparation before painting or clears.
• Metal: removal of rust, old paints, preparation before new painting.
• Plastic: smoothing edges, preparation for better adhesion of paints or adhesives.
• Drywalls: sanding joints and small imperfections before painting.

Sponges vs Abrasive Rollers

• Abrasive sponges:
  • Flexible, perfect for curved or irregular surfaces.
  • Ideal for precision work and detailed finishes.
• Abrasive rollers:
  • Designed to quickly cover large flat surfaces.
  • More durable, suitable for intensive sanding.

Common applications

• Finishing work: smoothing between layers of paint or clears.
• Repairs: preparation of damaged surfaces before intervention.
• DIY: polishing, deburring, preparation of substrates.
• Preparation before painting: ensures a smooth base for optimal paint adhesion.

Application method

1. Surface preparation: clean and dry surface, removal of grease and dirt.
2. Choice of sponge / roller: select the grit size suitable for the work to be done.
3. Application: make circular movements applying even pressure.
4. Control: regularly check the surface condition, adjust grit size for finishing.
5. Cleaning: remove dust residues with a clean cloth or vacuum cleaner.
6. Final inspection: ensure the surface is smooth and ready for painting or clears.
