Eco Concrete Etcher is a water-based non-hazardous, non-corrosive, biodegradable, odorless, VOC free, non-flammable concrete etching and cleaning solution. This advanced formula incorporates a special blend of organic chemicals and surfactants for the most effective user and environment friendly concrete etching solution available. It does not contain phosphoric or hydrochloric (muriatic) acids which present health and environmental risks including toxic fumes and corrosive run-off.

Traditionally concrete has been etched with hydrochloric acid also known as muriatic acid. The main disadvantages of muriatic acid is that it is a corrosive liquid made from hydrogen chloride gas which is very difficult to handle. It will aggressively corrode metal surfaces and it fumes excessively making it very difficult to use in enclosed spaces. It is also dangerous for human beings as contact with the skin causes burns, ulcers and dermatitis of the skin. Contact with the eyes can lead to partial or complete loss of vision. Burning of the mouth, esophagus, and stomach occurs after swallowing hydrochloric acid.

The threshold for tolerably safe exposure is 10 parts per million (ppm); even brief exposure to 35 ppm can irritate the throat. Individuals cannot stand being exposed to concentrations in the range of 50 to 100 ppm, and exposure to 1,300 to 2,000 ppm of hydrochloric acid is fatal. According to the American Association of Poison Control Centers Surveillance System In 2002, 3,452 individuals exposed to hydrochloric acid of which 22 people had a severe reaction, with life-endangering medical complications that resulted in disability, and 2 died from exposure.

The problems of muriatic acid has led to the need for an environmentally and user friendly alternative and hence the development of Eco Concrete Etcher to eliminate the above risks and harmful effects. This product is also ideal for cleaning, degreasing and acid etching concrete floors, walls, basements, garages, factories, warehouses, driveways, swimming pools, patios, and containment areas prior to coating, staining or sealing. Use on concrete, masonry, cinder block, brick, mortar joints and grout to properly prepare substrates for optimum penetration and adhesion of stains, paints, industrial coatings, and sealers. It also removes dirt, clay, mortar deposits, rust and efflorescence and reduces the pH of new concrete which can burn off sealers, paints and stains.


Eco Concrete Etcher is available as a ready to use product available in quart bottles, 1 gallon jugs, 5 gallon pails, 30 gallon drums or 55 gallon drums which all ship as non hazardous. Eco Concrete Etcher covers approximately 100 to 200 sq. ft. per gallon depending on the concrete porosity. Apply with a pump up sprayer or watering can and scrub the surface with a stiff brush for 15 minutes without allowing the product to dry out. Rinsing thoroughly with water 2 or 3 times to neutralize the etching action.

In the video below an egg is lowered into the Eco Concrete Etcher solution and it can be seen that almost instantaneously the product begins to dissolve the calcium based shell of the egg. The product uses the same kind of reaction to react with the alkaline concrete to open up the pores to make it more absorbent for sealer application.
