About Sanding Sequence Planner
A flawless finish starts with correct sanding. The golden rule is never to skip more than one grit grade - each grit must remove the scratch pattern left by the previous one, progressively refining the surface. This planner builds the right grit-by-grit sequence for your wood and surface condition, from coarse stock removal through to your chosen finish grit.

Method & Rules
Progress through grits: 80 -> 120 -> 150 -> 180 -> 220 ...Never jump more than ~one grade (avoid over ~1.7x increase)Each grit removes the scratches of the previous gritAlways sand with the grain, not across itRemove all dust between grits to avoid stray coarse scratches
Frequently Asked Questions
Why can't I jump from 80 to 220 grit?
Each grit leaves scratches of a certain size. A finer grit can only remove scratches slightly larger than its own - it cannot erase the deep gouges of a much coarser paper in reasonable time. Skipping grades leaves coarse scratches that stay invisible until you apply finish, when they suddenly show. Step through the grades.
What grit should I finish at?
For most furniture, 180-220 is the sweet spot - smooth, and open enough to take stain evenly. Go to 320+ only for oil finishes or between coats of lacquer. Beware over-sanding: past about 240 on some dense woods the surface burnishes and can reject stain, giving a blotchy result.
Does the wood species change the sequence?
Yes, to a degree. Soft, open-grained woods sand fast and can start finer; hard, dense woods may need an extra step and benefit from a slightly lower final grit to keep the surface receptive to finish. Resinous species clog paper quickly, so fresh abrasive and dust removal matter more.
