Paint marker

From Wikipedia, the free encyclopedia

A paint marker is a type of marker pen that is used to create permanent writing on a variety of surfaces from paper to metal to stone.

Unlike most permanent markers the ink is an oil based paint and generally requires shaking before use, similar to an aerosol spray paint can. In addition to that, the line is very opaque and unlike spirit-based or other permanent inks, does not fade due to exposure to UV light, and overlays all other colors beneath it. Paint markers like permanent markers generally contain the toxic compounds xylene or toluene, introducing some danger when used.

Like spray paint these markers give off volatile organic compounds which can be dangerous when not used in a well ventilated area or with a particulate mask. Gloves can also be worn to avoid absorption through the skin. Also like spray paint these types of markers are not truly permanent as they can be removed using high pressure cleaning, paint thinning solvents such as acetone, or they can simply be painted over.

Another type of paint marker is the solidified paint pen. This is a type of marker, often contained within in a twist tube, that is a cylinder of semi-hardend oil-paint with a pointed tip. As you write with it it wears down the point, and you need to advance to in order to continue writing. The marker leave a mark similar to that of chalk. It is useful for marking on wet or oily surfaces. It is sold under the brand name MeanStreak in the United States. It is made by Sanford, the maker of sharpies, but there are many different brands and types of solidified paint pens.
