Choosing a Finish for Furniture Made in Vietnam
June 15, 2026
Finish decides how a wood product is judged. Customers rarely notice a joint, and they always notice a surface that feels rough, marks with a glass of water or arrives three shades off the sample.
It is also the step with the widest quality spread among Vietnamese factories, because it depends on dust control, spray discipline and drying space rather than on machinery you can point at.
The finish families
Penetrating oil. Soaks into the wood rather than sitting on it. Natural look and feel, easy to repair with a wipe, forgiving of small defects. Low water and heat resistance, and it needs re-oiling once or twice a year outdoors. Standard for outdoor acacia and for butcher blocks and boards.
Hardwax oil. Oil with a wax component that builds a thin surface film. More protection than straight oil, still repairable locally. Popular for interior tables and flooring in Europe.
Polyurethane lacquer. Solvent based, sprayed, usually a sealer plus one or two topcoats. The workhorse of Vietnamese export furniture. Hard, water resistant, available from matt to gloss, cheap and fast. Repairs badly: a deep scratch means stripping a whole surface.
UV cured coating. Roller or spray applied and cured under UV lamps in seconds. Very hard and very consistent. Requires flat parts and a line, so it suits panels, flooring and doors rather than shaped parts.
Water based coating. Lower emissions, less odour, increasingly requested by European buyers. Costs more, raises the grain so it needs a de-nib sanding step, and it is less forgiving of humidity during application.
Paint. Primer plus topcoat, usually on rubberwood or MDF. Hides the substrate completely, so it is paired with the cheapest acceptable material. Requires excellent surface preparation because paint shows every filled defect.
Cost, lead time and durability, in relative terms
| Finish | Relative cost | Added lead time | Durability | Repairable |
|---|---|---|---|---|
| Oil | Low | Low | Low | Very easy |
| Hardwax oil | Medium | Low | Medium | Easy |
| PU lacquer | Low to medium | Medium | High | Hard |
| UV coating | Medium | Low on a line | Very high | Hard |
| Water based | High | Medium to high | Medium to high | Medium |
| Paint | Medium | High | Medium | Medium |
Paint carries the most lead time because of preparation, filling, sanding between coats and the rejection rate. Buyers routinely underestimate this and then wonder why a painted range quotes longer than a stained one.
Writing a finish specification a factory can actually hit
Most finish disputes come from a specification that is a word. “Natural oil” or “walnut stain” is not a specification.
A workable finish spec has six parts.
The system. Name the family and the number of coats. For example: sealer plus two coats two component PU.
The sheen. As a gloss value at a stated angle, not “matt”. Matt means different things in two factories.
The colour. Against a physical limit sample, not a photograph or a digital colour code. Wood substrates make digital references useless.
The substrate condition. Sanding grit before finishing, and whether the grain is filled.
The coverage. All faces including undersides and backs, or stated exceptions. This matters for moisture as much as for looks, as covered in the moisture content guide.
The test. If the product needs one: a water resistance, a cross hatch adhesion or a scratch test, with the standard named.
Colour matching on a variable substrate
This is where acacia programmes go wrong. Acacia has genuine board to board colour variation. Put one stain over it and you get a range, not a colour.
Two habits fix it.
Approve a range, not a piece. Sign a light limit sample and a dark limit sample and state that production must fall between them. Any piece outside the range is rejectable, any piece inside it is not.
Agree the sorting rule. Does the factory sort boards for colour before glue up, so each top is internally consistent? That costs yield and it is the difference between a table that looks designed and one that looks assembled from scrap. Say which you want.
Also name the light source for matching. A colour approved under warm workshop light and inspected under retail LED will look like a different colour.
Rubberwood avoids most of this because it is pale and even, which is one reason it is the default for stained and painted programmes. See the acacia versus rubberwood comparison.
Outdoor finishes are a maintenance decision
Outdoor acacia is almost always oiled, because a film finish outdoors eventually cracks and peels and then has to be stripped rather than refreshed.
The consequence is that your customer has to re-oil. If they do not, the wood greys and surface checks appear, and you will receive that as a complaint.
Two ways to handle it. Supply care instructions in the carton and make them explicit about frequency. Or specify a pre-weathered grey finish so the greying is the intended look rather than a fault. The second option removes the complaint entirely and some brands now prefer it.
What to inspect
At the sample stage: sheen, colour against both limit samples, coverage on undersides, and feel with your hand across the grain.
In production: the same checks on a random sample, plus a look at the drying area and the dust levels. Almost every finish defect in a Vietnamese plant is contamination, not coating.
The quality inspection guide covers where finish checks fit into the wider inspection sequence.
Frequently asked questions
Which finish is most durable for a dining table?
A two component polyurethane lacquer or a UV cured coating gives the hardest, most water resistant surface. Oil looks and feels better and repairs easily, but it marks with water and needs re-oiling. Pick based on whether your customer will maintain the piece.
Why do colour samples never match in production?
Wood is not a uniform substrate. The same stain on a light acacia board and a dark one gives two different results. Approve a colour range with a light and a dark limit sample rather than a single piece, and match under a named light source.
Is a water based finish available in Vietnam?
Yes, and it is increasingly common because European customers ask for it. It costs more, needs better spray discipline and raises the grain so it takes an extra sanding step. Expect a price and a lead time difference.
