If the concrete is contaminated with grease or oil, degreasing prior to etching is suggested otherwise the concrete will not etch evenly or adequately. A suitable degreaser like Nu-EcoSafe Degreaser is recommended as this is also a water-based product that is more environmentally friendly that its competitors. Several applications may be required to ensure a clean finish.
Acid etching is a vital part of the preparation process to ensure a perfect finish. Always consult the technical data sheets to ensure you use the correct mixing ratio for your concrete surface. Dan Blum October 18, at pm Permalink. Eli Richardson February 8, at pm Permalink.

Some of these are a blend of chemicals, including muriatic acid and phosphoric acid, and some contain very mild non-toxic acids. These specialized chemicals are a safer alternative to muriatic or hydrochloric acid as they give off fewer fumes, and the eco-friendliness of some products means that they do not require neutralization. However, they can be more expensive and some of them less effective.
Let us take a look at the types of acids available for etching concrete. Muriatic acid is the most common and most effective acid used for etching concrete. Muriatic acid is an unrefined variant of hydrochloric acid, and can be identified by its yellow hue, which is due to its high iron content.
It is a very powerful acid that is used to clean masonry of rust and excess mortar, but it can also eat away at fabrics and corrode most metals. It can burn skin and the noxious fumes can damage your lungs and nasal passages if inhaled.
This is why great care needs to be taken when working with muriatic acid. As well as being found in gastric acid — also known as stomach acid — hydrochloric acid is also used to process steel, treat swimming pools , and is used in the manufacturing of batteries.
Hydrochloric acid can also be used in the etching of concrete. It is just as powerful as muriatic acid and therefore the same amount of care should be taken when handling it.
Phosphoric acid is a weak acid that is found in household cleaning detergents and is often used as a food additive. It is far safer to work with than muriatic acid and hydrochloric acid. The downside is that along with being less effective, it is not widely available and it is more expensive. Citric acid is found in citrus fruit and is widely used in the food manufacturing industry. Because it is a weak acid, it has a longer reaction time than muriatic acid or hydrochloric acid, which means that it takes longer to etch the surface of the concrete.
Just like phosphoric acid, it is safe to use and less protective gear needs to be worn, although it does come at a higher price. This is a specialized product that is designed for ease of use in DIY projects. It is environmentally friendly and safe to use around plants and lawns.
The formula does not contain dangerous chemicals or noxious fumes. Etching concrete can be a daunting task. You can start by gathering the supplies that you will need and then follow the steps below. As long as you have all the supplies necessary and follow the safety precautions, you will be all set to begin etching concrete with muriatic acid.
What follows is a step-by-step tutorial on how to acid etch concrete with muriatic acid. Once you have gathered all the necessary supplies and safety gear, you will be ready to begin etching your garage floor. Be sure to read the tips and tricks at the end of this article on etching concrete successfully.
Remove all equipment and furniture from the room. Anything that has to remain in the room needs to be covered with plastic sheeting to protect it from potential splashing of the acid.
It is important to remove all dust, debris, oils, or dirt from the surface of the concrete before proceeding with the acid wash. A patch of oil or a bit of debris can act as an acid resistant that will stop the etching in that area, thus creating an uneven surface on the concrete. Begin by sweeping the floor thoroughly and then use an industrial degreaser to remove any grime, dirt, or oil from the surface of the concrete.
