One Quick Knowledge Question
You want to remove old paint from a wooden chair. Where do you start?
Meet the Grit System
Sandpaper isn't one thing — it's a system. Each grit number tells you how coarse (lower) or fine (higher) the abrasive is. Use coarse grits to remove material fast (old finish, deep scratches). Use finer grits to smooth. The pro move is to STEP UP through the grits — 80, then 120, then 220 — never skipping more than one level. Skip a step and the rough scratches from the previous grit show through your final finish.
The Grit System (Lower = Rougher, Higher = Smoother)
Skipping grits is the #1 mistake. People go from 80 straight to 220 thinking they're saving time. Then they stain it and every gouge from the 80 shows through. Step up. Always.
Three Sanding Tools
Sanding Block
Hand-held. Best for small surfaces, edges, between-coats. $3.
Orbital Sander
Electric, palm-sized. The workhorse for flat surfaces. $40-$80.
Detail/Mouse Sander
Triangle-tip, gets into corners. Detail work on furniture.
Watch It Done Right
How to Use It — The Five Moves
- Pick the right grit. Strip = 60-80. Smooth bare wood = 120. Pre-finish = 180-220. Between coats = 220. Final = 320+.
- ALWAYS sand with the grain. Sandpaper scratches in the direction you push. Sanding ACROSS the grain leaves visible scratches no finish will hide.
- Step up gradually. Never skip more than one grit. 80 → 120 → 180 → 220. Each grit removes the scratches from the last one.
- Wipe dust between grits. A tack cloth or damp rag picks up residue. Skipping this means coarse dust contaminating your fine sanding.
- Feel, don't look. Run your bare palm over the work. Your hand catches bumps your eye misses. Smooth like a baby's skin = finished.
Sanding is meditation. Don't fight the wood. Light pressure. Let the paper do the work. Push too hard and you'll make hollows, burn the wood, or wear through veneer.
The 'Free Furniture' Move
Curbs in your neighborhood throw out solid wood furniture every week — dressers, end tables, chairs. Most are dull, scratched, or paint-tired. Three hours of sanding and a coat of stain = a Restoration Hardware piece for the cost of a coffee.
The flip path: Curb-find → strip → sand → stain → finish → sell on Facebook Marketplace for $150-$400. People in my generation called that 'a Saturday job.' Now it's a small business.
Safe & Unsafe
✅ Safe
- Dust mask (N95) — sanding dust is bad for lungs
- Eye protection
- Work outdoors or with ventilation
- Vacuum between grits
- Empty sander dust bag often — fires happen
⚠️ Unsafe
- Sanding without a mask (long-term lung damage)
- Sanding lead-paint surfaces without proper PPE (pre-1978 homes!)
- Heavy pressure on power sanders (burns the wood)
- Sanding across the grain
- Wet wood — sandpaper gums up instantly

Sand a piece of wood through the full grit progression
Start at 80, step up to 120, 180, 220. Photograph the surface at each stage.
