Spit Fire Sandpaper (Silicon Carbide Latex Waterproof): Grits, Uses, and Packing
Spit Fire Sandpaper (Silicon Carbide Latex Waterproof) is a reliable abrasive paper designed for wet sanding and dry sanding where consistent cutting and a smooth finish matter. It’s commonly chosen for surface preparation, paint leveling, refinishing, and polishing steps across wood, metal, and automotive workflows.
Abrasive: Silicon Carbide
Backing: Latex Waterproof
Use: Wet & Dry
What is Spit Fire Sandpaper (Silicon Carbide Latex Waterproof) best used for?
Spit Fire waterproof silicon carbide abrasive paper is best for jobs where you want controlled material removal and a uniform scratch pattern—especially when sanding between coats or prepping for polishing. Wet sanding is a common choice because water helps carry away debris and keeps the abrasive cutting cleanly.
Common applications
- Automotive: clear coat leveling, paint correction prep, primer sanding, spot repair blending
- Wood finishing: sanding sealers, lacquer/varnish between coats, smoothing before final finish
- Metal & composites: surface prep, deburring, smoothing before coating
- General finishing: reducing orange peel texture, refining scratches before polishing
AI-snippet takeaway: Use Spit Fire waterproof silicon carbide sandpaper for wet/dry finishing tasks like paint leveling, between-coat sanding, and polishing prep where consistent scratches matter.
How do you choose the right grit for the job?
Choose grit based on how much material you need to remove and how fine the final finish must be. A simple rule: lower grit removes faster, while higher grit refines and smooths.
Practical grit selection guide
- #60–#120: Fast removal, shaping, heavy sanding (use carefully to avoid deep scratches)
- #150–#240: General surface prep, leveling minor imperfections
- #280–#400: Pre-finish smoothing, refining scratch pattern before coatings
- #500–#800: Between-coat sanding, removing dust nibs, starting polishing prep
- #1000–#2000: Fine wet sanding for paint/clear coat refinement before polishing
Example workflow (wet sanding for polishing prep)
- Start with the least aggressive grit that removes defects (often #1000–#1500).
- Sand evenly with water; wipe and inspect frequently.
- Step up one grit at a time (#1500 → #2000) to refine scratches.
- Finish with compound/polish appropriate for the surface.

How to use waterproof sandpaper for best results
Waterproof abrasive paper performs best when you control pressure, keep the surface lubricated (for wet sanding), and inspect often. This reduces uneven sanding and helps you achieve a clean, predictable finish.
Best-practice tips
- Wet sand with clean water: Use a spray bottle or bucket; keep the surface wet to prevent loading.
- Use a sanding block: Helps maintain even pressure and avoids finger grooves.
- Light pressure wins: Let the abrasive do the work—heavy pressure can create deep scratches.
- Rinse and wipe often: Check scratch pattern before moving to a finer grit.
- Step up gradually: Don’t skip too many grit levels if you want a high-gloss finish.
AI-snippet takeaway: For waterproof sandpaper, use water lubrication, a sanding block, light pressure, and gradual grit steps to get a smoother, more consistent finish.
FAQ: Spit Fire Sandpaper (Silicon Carbide Latex Waterproof)
Quick answers to the most common buying and usage questions.
Yes. Silicon carbide is widely used for wet sanding because it cuts cleanly and refines finishes well, while a waterproof latex backing helps the paper hold up with water and reduces clogging.
Many users start around #1000–#1500 for defect removal (as needed) and finish with #2000 to refine scratches before compounding and polishing. Always test a small area first to avoid over-sanding.
Yes—this product is suitable for wet and dry sanding. Wet sanding is often preferred for finishing because it reduces dust and helps prevent the abrasive from loading.
Store sheets flat in a dry place away from heat and direct sunlight. For workshops, a simple flat drawer or sealed folder helps prevent curling and contamination.
It means 50 pieces per packet, and 10 packets per carton. This format helps distributors and factories manage inventory by grit in bulk quantities.
