Oil-Based vs Water-Based Paint Markers: Which One for Glass, Wood, Rocks and Fabric

Oil-based paint markers are the usual pick when a mark has to stay on a smooth surface such as glass, metal or plastic, and dried oil-based marks are harder to remove. Many water-based markers dry fast, layer cleanly on paper, wood and stone, and may wipe off smooth surfaces until sealed. Choose by surface and by how long the piece has to last, then check the specific marker's label, because ink base alone guarantees nothing.

Pick the wrong paint pens and the trouble shows up later: window art that won't come off in January, or pantry-jar lettering that smears the first time someone wipes the shelf.

What is the difference between oil-based and water-based paint markers?

Both kinds put opaque pigment on the surface, which is why a white paint marker shows up on a black card where a felt-tip disappears. The first difference is the base: water, or a nonwater base that may be oil or solvent. The rest of the formula, especially the binder or resin, also affects drying, adhesion and cleanup, so check the marker's listed surfaces and removal directions.

A Clemson University Occupational and Environmental Safety fact sheet describes water-based paints as paints that use water as the liquifying solvent for the pigments. Its companion sheet groups oil-based and solvent-based paints as "nonwater-based" and describes oil paint as pigment suspended in a drying oil (Clemson OES, water-based; Clemson OES, nonwater-based).

In practice, many water-based markers stay put on porous surfaces but may wipe off smooth ones. Our own Artline lines work this way: Decorite is wet-erasable on glass and plastic, and Poster Markers wash off non-porous surfaces. Oil-based markers are the usual choice where a mark must hold on a smooth surface. Formulas vary, so read the label.

Drying, cleanup and odor: what changes at the craft table

Drying and curing

Artline Poster Markers are fast drying, with colors that can be layered and overpainted without bleed-through, and Decorite colors can be layered once the ink has dried. The EK-400 is fast drying too. Touch-dry is not fully hardened, though, and Clemson notes that oil paint is slow-drying. Follow any cure guidance on the label.

Cleanup and mistakes

On a window, Decorite is wet-erasable, while Poster Markers wash off non-porous surfaces. For dried oil-based marks, start with the removal directions on the marker's label. If those call for a solvent, Clemson's safety office advises odorless mineral spirits over ordinary mineral spirits or turpentine, neoprene gloves when cleaning with them, and a window exhaust fan for ventilation. Check that the solvent is compatible with the surface by testing a hidden spot. The CPSC adds: keep solvents out of the drain unless local sewer rules allow it, and store solvent-soaked rags in a closed container, since they can catch fire on their own. For paint on skin, the CPSC says not to use solvents and to use soap and water, baby oil or a skin cleanser instead (CPSC Art and Craft Safety Guide).

Odor, ventilation and the AP seal

The U.S. Environmental Protection Agency lists paints, solvents, permanent markers and craft materials among household sources of volatile organic compounds, and its advice is to increase ventilation and follow label directions (EPA). The CPSC's guide puts it simply for markers: ensure appropriate ventilation or use water-based markers. Water-based is not hazard-free, though; Clemson notes some acrylics contain small amounts of ammonia and formaldehyde. Our Artline EK-400XF paint markers are low odor and xylene free.

For a classroom or a kids' craft night, look for the AP (Approved Product) seal. The Art and Creative Materials Institute says the seal marks products a toxicologist has evaluated as containing nothing in amounts toxic or injurious to humans, including children (ACMI). Artline Decorite sets and the EK-400 are AP Certified.

Which paint marker works on which surface?

The surface list on the specific marker decides it. As a starting point, water-based ink suits porous surfaces (paper, raw wood, unsealed stone) and temporary work on glass; oil-based ink suits smooth surfaces where the mark has to survive handling.

Glass, ceramic and plastic: the smooth surfaces

What are the best paint markers for glass?

Use water-based ink for glass art that should come off and oil-based ink for glass you want to keep. A second-grade teacher drawing a turkey on the classroom window wants it gone by December, so water-based ink is the right call. Artline Decorite is wet-erasable on glass and plastic, and Artline Poster Markers wash off non-porous surfaces, which suits window graphics and holiday lettering on a shop door.

For a keeper, like a labeled pantry jar or a hand-lettered vase, use a permanent marker such as the EK-400. For gold or silver lettering on a glass gift, Artline SUPREME Metallic is an instant-drying permanent marker for plastic, glass and many other surfaces, and it does not need shaking.

Porcelain and glazed ceramic

Both the EK-400 and Decorite list porcelain. Decorite is wet-erasable on non-porous surfaces, so the EK-400 is the permanent option for a porcelain display piece.

We don't make food-safe or dishwasher-safe claims for these markers, so keep designs away from food-contact and lip areas.

Plastic

Storage bins and toy boxes are smooth, so oil-based ink is the usual pick for permanent labels. Try a dot on the underside first, because plastics vary. For a label you plan to change each season, water-based Decorite is the friendlier pick because it stays wet-erasable on plastic.

Wood, rocks, paper and fabric: the porous surfaces

Which paint markers for wood work best?

Both types can work on wood; the finish and the weather decide which. Raw wood drinks ink along the grain, so lines can feather on rough pine. Sand the face smooth and, for crisp lines, seal or prime it first. For a decorative indoor sign, water-based Poster Markers layer easily. For a cedar planter label or a porch sign that will see rain, the EK-400 is a good candidate, since we list it for wood and for indoor and outdoor use. Our Artline paint marker collection carries it and its sister sizes.

Painted rocks

Water-based paint markers are a common choice for decorative rocks. Scrub the rock, let it dry completely, lay a white base coat on dark stone, and draw on top. We list stone among the surfaces for Artline Poster Markers. If the rock will live in a garden bed, consider a clear outdoor sealer, following the sealer's label and testing it over a scrap of the same marker first. For flower pots and garden stake labels, the Artline Garden Marker (EK-780) is rated quick drying, UV resistant and waterproof.

Paper and cardstock

For paper and cardstock, water-based ink is usually easier to layer and control. Decorite's high-density pigment shows on dark greeting cards and craft paper, and colors can be layered once dry. Poster Markers allow overpainting without bleed-through. For brush lettering, Artline SUPREME Brush Markers have a brush nib that draws both wide and fine lines.

Fabric

Fabric isn't on the surface lists for the EK-400 or Decorite, so use a marker built for cloth. The Artline Marker for Fabric (EKC-1) uses fast-drying, water-based pigment ink made for dark and colored fabrics, and the marks stay clear through repeated washing. The laundry marker is available in 3 colors and is ideal for light colored fabrics. Artline Shirt Markers use an iron-on setting process instead.

Which Artline markers are oil-based and which are water-based?

Oil-based: Artline Paint Markers

The Artline paint markers we carry include the Artline EK-400 2.3mm bullet, and the collection also carries the EK-409, EK-440 and EK-444. All four use the same permanent, oil-based, xylene-free pigment ink. We recommend the EK-400 for mural painting and arts and crafts as well as job sites. If your project is steel, pipe or welds rather than a garden sign, see our guide to the best paint marker for metal.

Water-based: Decorite, Poster Markers and the fabric marker

Decorite uses water-based pigment ink that is xylene free, acid free and fade resistant, for card, glass, porcelain, metal and plastic. The Artline Decorite marker sets come in a 1.0mm bullet, a 3.0mm flat tip and a brush nib, in pastel, metallic and neon packs. Poster Markers use highly opaque, water-based liquid pigment ink with valve action, rated water and fade resistant. The EKC-1 fabric marker is water-based too.

Alcohol-based and solvent-based: SUPREME Metallic, Garden Marker and Wetrite

Artline SUPREME Metallic and the Artline Garden Marker (EK-780) use alcohol-based ink. Wetrite (EK-47) uses hydrocarbon solvent-based ink and is specified for wet, non-porous surfaces such as metal, plastic and styrene foam.

How to prime a valve-action paint marker

Artline paint markers work by valve action, so ink has to be pushed down to the nib before the first stroke. Here's how we recommend priming one:

Paint Marker2.3mm bullet tipPoster Marker2.0mm bullet tipFabric Marker1.2mm bullet tip

1. Remove the cap and hold the marker with the nib pointing up.
2. Press the nib down once with your thumb to release air.
3. Replace the cap and shake the marker well.
4. Press the nib lightly a few times until ink flows. (Our tip: do this on scrap paper, not on your project.)
5. Don't press hard. Too much pressure causes blotting.
6. If the color fades mid-project, wipe the nib with a tissue or cloth.

Two more details: the ink cannot be refilled, and spare nibs are available for every size except the EK-444XF.
