Acrylic or Oil-Based Paint Markers: Choosing by Surface
Paint markers are the fastest-growing category on the counter and the one with the most confusion attached, because two quite different products sit side by side under the same name. Choosing the wrong one is the most common reason a marker gets brought back.
Water-based acrylic markers
These are acrylic paint in a pen. They dry fast, they are permanent on porous surfaces once dry, and they clean up with water while wet.
Best on: paper, card, canvas, primed board, raw and sealed wood, terracotta, and anything with a surface the paint can key into.
Weaker on: glass, glazed ceramic, metal and plastic. They will sit on those surfaces and scratch off.
They also layer well, which matters for illustration — a second colour goes over a dry first without lifting it.
Oil-based paint markers
These use an oil-based paint and a solvent carrier. They dry slower, smell noticeably stronger, and require ventilation.
Best on: glass, metal, plastic, stone, glazed tile, dark surfaces of any kind.
Where they shine: opacity. Metallic and light colours from an oil-based marker cover a black surface in one pass in a way water-based markers rarely manage.
Trade-offs: slower drying means more smudging risk, layering needs patience, and clean-up needs solvent.
Choosing by job
- Sketchbook, illustration, canvas: acrylic.
- Lettering on dark card: oil-based metallic.
- Glass jars, mirrors, tile: oil-based.
- Painted wood signage: acrylic.
- Model and miniature detail: acrylic, fine nib.
- Fabric: acrylic, heat-set. Oil-based will not work.
Both types are listed with their intended surfaces under paint markers and pens.
Priming a new marker
Valve-action markers need priming, and doing it on the work is how people ruin a first piece.
- Shake vigorously with the cap on — the mixing ball should be audible — for at least thirty seconds.
- Press the nib down on scrap paper repeatedly until paint flows.
- Test the line on the same scrap.
Re-shake periodically during use. Pigment settles, and a marker that starts strong and goes pale usually just needs shaking rather than replacing.
Nib size
Fine nibs for detail and lettering, medium for general work, broad and chisel for fills and large lettering. Chisel nibs give both a thin and a thick line depending on the angle, which makes them the most versatile single choice.
A big colour range with the wrong nib is less useful than a small range with the right one. Buy the size you will actually use.
Storage
Store markers horizontally. Stored upright, pigment settles to one end and the marker either floods or runs dry depending on which way up it was.
Caps on firmly. A partly open cap dries a nib within a day, and a dried nib on a valve marker is usually the end of it.
Sealing the finished piece
On anything that will be handled — a painted mug, a jar, a tile — a clear sealant substantially extends the life of the work.
Match the sealant to the marker: water-based varnish over acrylic markers, solvent-safe sealant over oil-based. And test on a scrap first, because some sealants reactivate marker ink and smear it.
Nothing done with a marker is food-safe or dishwasher-safe unless the product explicitly says so. Keep painted areas away from the rim and the mouth of drinkware.
Markers alongside paint
Markers and brush paint work well together — a base laid in with brushed acrylic and detail added with a marker once dry is a common and effective approach.
Just keep the chemistry consistent: acrylic markers over acrylic paint, and let each layer dry fully. Paint sets are under acrylic paint sets, and mediums for the brushed layers under pouring and fluid mediums.

Key points
- Water-based acrylic markers suit porous surfaces: paper, canvas, wood, primed board.
- Oil-based markers cover dark and non-porous surfaces — glass, metal, plastic, stone — far better.
- Shake before priming, and prime on scrap paper, not on the work.
- Store markers horizontally so pigment does not settle at one end.
- Nib size matters more than colour range for line work; buy the size you will actually use.
- Acrylic markers can usually be heat-set on fabric; oil-based ones cannot.
