muriatic acid should not cause discolouration to concrete it will eat it away though.
yes,you use acid
Concrete is very hard. To do any good in etching it you need something very strong. Muriatic Acid is the only thing that I have found that works. How strong you mix it depends on the concrete. Some concrete that was poured with a lot of water in the mix will need less Acid. Concrete that is smooth and hard will take more. Muriatic Acid is caustic. Read the direction. Use rubber gloves; safety glasses; and a respirator. For a large project, such as a driveway or Patio. Use a plastic garbage can. Fill with 10 gallons of water. Carefully pour one gallon of Muriatic Acid into the water and mix with a wooden paddle. Take a plastic watering can and fill it with the solution. Wet your concrete with a water hose, then carefully pour the Acid solution onto the concrete. It will bubble and foam. This is the acid etching the concrete. Let it set for about 15 min. Scrub with a stiff push broom, and then rinse with a water hose. The acid will kill plants and grass. Steve Schillinger sds@knology.net = Safety Note = Make sure you put the water in the garbage can first--adding water to acid is a sure way to get splashed with concentrated acid.
First you must pressure wash as best as possible. Next you need to acid wash the concrete. Finally you should be able to neutralize the acid with a vinegar and water solution. Let dry. You should prepare the whole floor this way.
Try a mixture of 75% water, 25% muriatic acid (hardware stores). [wear protective gloves, googles, boots]
its is something that neutralizes the concrete! :)
from my point of view muriatic acid can not soften concrete but can affect minimal with the help of pounding the surface and spraying or painting with muriactic acid then repeating several times until it breakdown
Muratic acid is another name for hydrochloric acid, so it is not the same thing as sulfuric acid.
i want to clean algi from pontoons on my pontoon boat,,can muratic acid be used??????
With a strong acid, like muratic acid used to clean concrete. Gold will be unaffected by the acid. However if it's gold plated or a gold alloy (not 24K gold) it will react to the acid.
You do not use muratic acid with car batteries. You use sulfuric acid. You use about 35% Sulfuric acid and 65% Distilled (de-ionized) water
muratic acid
It is inorganic.
Muratic acid. Or however you spell it. 1/3 acid/ water. Do not use if it is sealed or stained.
Call poison control. That is hydrochloric acid.
That depends on what you're trying to clean off. Technically, muratic acid removes some of the chemicals that make up the surface of the concete. If the stain is deep you'll need to use a stronger concentration of the muratic acid. If it's just a weak surface stain, you can dilute the acid. The muratic acid will destroy any clothing, especially cotton, that it touches. Even a drop will disolve the cotton where it touches. Concentrated muratic acid that gets in your eyes can cause blindness, so make sure you wear something to protect your eyes. It burns if you get the acid on your skin, so wear gloves and have plenty of water nearby. Beyond that, just put water in a plastic pail then add muratic acid to get to the concentration that you want. I use an automotive wheel cleaning brush to clean with muratic acid, I also wear rubber gloves when I'm using the stronger concentrations. Brush it on, work it a little then rinse it off with water. It takes a small amount of concrete off the surface and changes the appearance of the concrete, but it also removes the stain.For cleaning concrete, I would recommend using a citrus degreaser instead of muriatic acid. It is much more environmentally friendly, and you don't have to be a chemist to use it. You can purchase it at any professional construction material supply store. Available in 1 gallon and 5 gallon. It also smells a lot better than muriatic acid!!
Muratic (not muractic) acid is a concentrated HCl solution.
Formula: HCl
