Markal 90900 Extra-large Liquid Paint Marker White

Product Description

The MARKAL 90900 is an extra-large liquid paint marker designed for marking and identification work across a wide range of industrial and trade surfaces. It uses an alcohol-based ink formulation that delivers bold, opaque white lines on materials including steel, iron, plastic, cardboard, glass, and pipe and tube stock. The extra-large tip size lays down high-visibility marks quickly, making it well suited for layout work, part identification, weld prep marking, and job-site labeling. Licensed tradespeople and industrial workers rely on this type of marker for durable marks that resist smearing once dry.

This marker sees common use in plumbing, pipefitting, fabrication, and general industrial environments where standard pens or chalk fail to show up on dark or reflective surfaces. It is effective on both ferrous metals such as steel and iron and non-porous surfaces such as glass and plastic. The alcohol-based ink adheres without primer or surface prep on most clean substrates, supporting fast-paced field and shop workflows.
