About Us

Rainbow Chalk Markers was first launched in 1994 developing and promoting its first product the Liquid Chalk marker. Through extensive advertising we became the market leader of this product. This lead to us obtaining the trade mark LIQUID CHALK in 1999.

Our knowledge of water-based products began to expand and further products were developed and brought to market, with the water-based Steel-writer and our DIY Grout Pen.

Rainbow Chalk Makers went onto invest into automated machinery so as to keep up with the growing market. Due to an increase in production it was necessary to expand. We moved to Essex in 2001 where we have recently had to double the size of the site, all of our manufacturing is carried out here where we distribute around the world.

We specialise in water-based non-toxic inks and paints, which are completely environmentally friendly and all conform to the ASDM-D4236 requirements.
