Harden the bare wood
Apply a coat of diluted urushi to the kiji to seal and stiffen the wood surface before any further work.

Foundational lacquerwork sequence and maki-e placement for a beginner moving from kintsugi to full lacquerware
A practitioner experienced in kintsugi and a single maki-e class wants to build basic lacquerware on wood panels and is unsure of the correct order of ground layers, the role of paper reinforcement, and where in the sequence a maki-e design should be introduced. The thread also touches on whether the full Wajima-style composite foundation is necessary for a hobbyist.
This page is written from one discussion thread. It records what practitioners reported and what they linked it to — not documented workshop practice. Every claim below links to the comment it rests on, so you can read it in context.
Raw urushi contains urushiol, a potent skin sensitiser. The reaction is delayed (often 24–72 hours) and can be severe. Practitioners in the thread note that gloves and long sleeves are standard precautions, and that once sensitised, even tiny exposures cause a blistering rash. The reaction is not a simple contact allergy that resolves; it is an immune response that can recur with increasing severity.
One commenter observes that the woodworking community's blanket refusal to recommend urushi stems from an overreaction to the urushiol risk, but the underlying hazard is real and the delayed onset of the reaction means a person may not realise they have been exposed until the rash appears.
What the thread establishes
The answer.
The thread establishes that the full multi-layer composite foundation associated with Wajima-nuri is one regional approach, not a universal requirement, and that a beginner can start with fuki-urushi on a simple panel. Where the full sequence is used, it proceeds from hardening the bare wood with diluted urushi, smoothing the grain with kokuso and sabi-urushi, embedding cloth or paper reinforcement in nori-urushi or mugi-urushi, building a smooth surface with further sabi-urushi, then applying nakanuri (the first coat of straight urushi), uwanuri (the final visible coat), a hardening coat of diluted urushi, and a multi-step polish. Maki-e and urushi-e are applied on top of the uwanuri after partial polishing; most kawari-nuri techniques go on the nakanuri layer; chinkin is engraved into a fully polished uwanuri surface. The thread stresses understanding the purpose of each step rather than mechanically copying a long list, and notes that historically the ground work and the decorative work were separate specialisations.
02
Smooth the grain and joints
Fill open grain, gaps, and joint lines with kokuso, ji-urushi, and sabi-urushi as appropriate to the defect.
03
Embed cloth or paper reinforcement
Adhere fabric or washi to edges, feet, or joined panels using nori-urushi or mugi-urushi, followed by ji-urushi and sabi-urushi to build the surface back up. The reinforcement adds structural durability and also limits wood movement caused by humidity cycling, because urushi is permeable to water vapour.
04
Build a smooth ground
Apply successive layers of sabi-urushi until the surface is completely flat and free of texture.
05
Apply nakanuri
Lay down the first coat of straight (undiluted) urushi. This is the middle coat that will carry most decorative work.
06
Sand nakanuri smooth
Flatten the cured nakanuri by abrasion before proceeding.
07
Apply uwanuri
Lay down the second coat of straight urushi. This is the final visible layer that will be polished to the finished surface.
08
Harden the uwanuri
Sand the uwanuri, then apply a thin coat of diluted urushi to harden and seal the surface.
09
Polish
Work through a multi-step polishing sequence, alternating between abrasion and rubbing in diluted urushi that is then wiped away, finishing with a final polish.
··Reported
What was reported
- Nori-urushi is a lacquer-and-rice-paste adhesive, distinct from mugi-urushi which uses wheat flour. ↗↗
- Maki-e and urushi-e are applied on top of the uwanuri layer, usually after it has been partially polished. ↗
- Most kawari-nuri techniques are applied on top of the nakanuri layer rather than the uwanuri. ↗
- Chinkin is engraved directly into a fully polished uwanuri surface and then infilled with gold leaf or powder. ↗
- Togidashi-maki-e embeds metal powder in a layer of urushi and reveals it by sanding the surface down, producing a fully flat finished surface. ↗
- Taka-maki-e raises the motif in shallow relief using several layers of urushi and filler materials, distinguishing it from the flat hira-maki-e. ↗
- Nashiji uses metal flakes embedded in urushi to create a pear-skin textured ground. ↗
- Choshitsu involves applying many layers of urushi in contrasting colours over the nakanuri and then carving through to expose the strata. ↗
- Ishime-ji is a textured surface made with powdered dried lacquer, applied over either nakanuri or uwanuri. ↗
- Historically and in larger production, the ground work (nuri-shi) and the decorative work (maki-e-shi) were performed by different specialists, each step being complex enough to constitute its own craft. ↗
- A lacquered chopstick can be completed in roughly five or six coats: diluted raw urushi, raw urushi, two colour coats, and two buffs of a translucent top layer. ↗
- When applying urushi to a curved or complex form, a small punt or suction-cup handle is attached so the piece can be rotated and the coat applied in one continuous pass, avoiding a visible seam between two separately cured applications. ↗↗
Limits of this source
What the thread does not answer.
- The opening post asks which specific type of washi is used for reinforcement; the thread discusses the function of the paper but does not settle on a particular grade or weight.
- The exact number of coats and the precise dilution ratios for each stage of the Wajima-style sequence are not specified; the thread gives the order but not the quantities.
- The thread does not address curing conditions (humidity, temperature, duration in a muro or furo) for any of the coats described.
- The relationship between the simpler fuki-urushi finish and the full composite sequence in terms of durability and suitability for tableware is mentioned but not fully worked out.
