What does acid etching do to concrete?
It remove the silicates the give concrete its smooth finish and creates a profile for mechanical adhesion.
How are you going to wash the concrete to get rid of all of the acid? If you don't get rid of all the acid, paint is not going to stick.
Etching of the old concrete with muriatic acid is sometimes done to slightly roughen the surface. There are also commercially available bonding agents available at concrete suppliers and at some home centers.
Muriatic acid,used for etching concrete and changing PH level in pools is a watered down hydrochloric acid available at most paint and hardware stores and Home Centers.
Nitric acid is the most effective, but can be dangerous to handle. Muriatic acid, which is sold to etch concrete, and sulphuric acid are also effective, as are a variety of chemical blends and slurries, called mordants, depending on exactly what kind of etching you are doing.
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… Read More
The difference between the two intaglio processes of etching and engraving is the use of acid. Engraving is a form of dry point and etching uses acid.
Hydrochloric acid is hydrogen chloride gas dissolved in water. It is a strong, highly corrosive, poisonous acid that has millions of uses in thousands of fields, from etching metal to cleaning concrete to digesting food in your stomach to lowering the pH of swimming pool water. It is also known as muriatic acid.
a stronger etching formula
Undetailed info: it has to do with "bathing" the etching sheets in mild acid baths
HF, Hydrofluoric acid.
it is affected by acid or etching
Cleans it and roughens it, usually so paint will stick better.
By applying "Hydrofluoric" acid.
Also used are hydrogen fluoride (HF) and sodium fluoride (NaF).
HF or Hydroflouric Acid
To prep the surface use quikrete etching stain. Quikrete offers a semi-transparent stain that gives it a two-tone look. It comes in a variety of colors. I know Lowe's offers it for around $25-$30 a gallon. Also they have a product that is etch and stain in one. Only certain Lowe's carries it. You may be able to special order it in.
It is used to regenerate solutions of sulfuric and hydrofluoric acid, and for etching leaded glass.
No. Muriatic acid will not remove paint from concrete. Muriatic acid will etch bare concrete though.
To test a concrete floor for sufficient dryness before painting you should tape a two foot by two foot square of (clear) plastic film to the floor, wait 48 hours and see if the concrete is darker under the plastic or if any condensation has occurred on the underside of the plastic. If so then the floor is not dry enough. If no condensation or darkness, paint.
It dissolves glass, hence its use in glass etching.
There are no chemicals that will soften concrete once it has set, but Muriatic acid (Hydrochloric acid) will etch/dissolve concrete over time.
Things found in etching creams: Barium Sulfate, Sulfuric Acid, Sodium Bifluoride, and Ammonium hydrogen difluoride. Hydrofluoric acid is the main ingredient that will etch glass. Overall, the cream is a diluted form of hydrofluoric acid. It's not nearly as dangerous as pure hydrofluoric acid but still, be very cautious when using it.
Etching is the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal (the original process-in modern manufacturing other chemicals may be used on other types of material
You can acid wash colored concrete. In addition to acid washing, it is a good idea to seal colored concrete as well so it does not stain.
No battery acid is too thin and will not stay in place plus there's not enough sulfuric acid in the liquid to do the etching.
An etchant is an acid that is used in etching. The chemical composition varies with the item to be etched but all are acid based.
I have etching in my inground concrette pool and i need to know how to fix it. the pool was made in 1973 i bought the house three years ago.
muriatic acid should not cause discolouration to concrete it will eat it away though.
They use hydrofluoric acid for glass etching and polishing. Also they use it for production of gasoline.
This depends on the type of acid. To put this simply: yes, there are certain acids which can dissolve concrete.
An etching is done by engraving the picture (with the help of acid) in a copper plate, which is used for printing a number of copies. It is usually black and white. An oil painting ismzde by applying oil paint with brushes on a canvas or board. Click link below to learn more about etching.
One of th more common acids used in jewellery making, cleaning and etching would be hydrofluoric acid, or HF(aq).
Richard J. Simonsen has written: 'Clinical applications of the acid etch technique' -- subject(s): Dental acid etching
yes,you use acid
It's a physical change because the chemical composition of the glass is not altered.
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Phantom of the Opera 1943, Georgette, the publisher's assistant, throws etching acid at Claudin.

Baking soda is the best way to remove acid stains from concrete. Dawn may remove grease stains from concrete. Vinegar is another great solvent for grease stains.
Any time you remove material (acid) you shorten the life of the original structure. By how much? That would depend on the amount of etching was done and how deep.
Acid overdosing destroys total alkalinity which leads to etching of the Marbelite surface. Always dilute acid before dosing, and add to the weir while the pump is running
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
Etching is a process to produce semiconductor devices. It is also used in printing. Wet etching and Dry etching are possible.
For acid etching during the sealant-application procedure, the teeth should be etched with phosphoric acid. It needs to remain on each tooth for a minimum of 15 to 20 seconds.
No, it is a chemical change. The glass is changed into new substances where it is etched.
The best approach here is to consider neutralizing the acid. a solution of baking soda and water will do the trick. Battery acid is strong and acidic. Any damage occurred to the concrete will be permanent. The effects you see from the acid coming in contact with the concrete will vary based on how much acid there was and how long it was left to etch into the surface. Hydrochloric and muriatic acids will eat… Read More
Etching is done with acid, its used to eat away material that is exposed to it and material that is covered is untouched Engraving is actually carving something with tools You could have found this out yourself using something thats available these days, called a SEARCH ENGINE
