By etching a concrete surface you are providing the adhesion needed for the paint to stick. For paint to stick the surface must be rough - it cannot be smooth or slippery in anyway or the paint will simply peel off.
Like doors and frames they need to be sanded back before they can be painted. The reasoning being that otherwise the gloss finish will not allow the paint to stick. By sanding it to create a rough finish so the paint has something to stick to.
When I say rough however - Don't misunderstand me as to think it should be really rough. The surface should still seem rather smooth however as long as its not glossy.
In the same way concrete needs to be etched or roughened so that paint can adhere to the surface. You can do this in two ways.
One is to use Hydrochloric Acid - Simply dilute it 1:10 or stronger if required and then tip it onto the concrete. Broom in and when fizzling has stopped rinse off. Make sure you rinse it off properly or it also will repel the paint.
Your other option which is becoming the more popular now (as people don't seem to follow instructions with the first and always and have problems) is to use a dinosander. Sand the surface down and rinse off - This is problem proof and easy to do. You can hire one from your local hire shop.
As I say both will work but the latter is becoming more popular as you can't go wrong.

Etching concrete indoors with muriatic acid?
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.

YES!
Can you paint the concrete floor as soon as muriatic acid etching dries?
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.

How is acid etching concrete used in the process of creating decorative patterns or textures on concrete surfaces?
Acid etching concrete is used to create decorative patterns or textures by applying an acid solution to the surface of the concrete. The acid reacts with the minerals in the concrete, creating a chemical reaction that etches the surface and reveals a unique design. This process can be used to add visual interest and texture to concrete surfaces, making them more aesthetically pleasing.
How to etch concrete for a decorative finish?
To etch concrete for a decorative finish, you can use a combination of acid etching and staining techniques. First, clean the concrete surface thoroughly and apply an acid etching solution to create a rough texture. Then, apply a concrete stain or dye to add color and depth to the etched surface. Finally, seal the concrete with a protective coating to enhance durability and longevity.
When etching concrete on basement steps will muriatic acid eat through the drain pipe at the bottom of the steps?
YES!
How can I create a unique design by etching concrete?
To create a unique design by etching concrete, you can use various tools like acid, stencils, or engraving tools to carve patterns or images onto the surface of the concrete. Experiment with different techniques and designs to achieve a personalized and distinctive look.
What is the best etching solution for concrete surfaces?
The best etching solution for concrete surfaces is a mixture of muriatic acid and water. This solution effectively removes dirt, grease, and other contaminants from the concrete surface, preparing it for further treatment or coating. It is important to follow safety precautions when using muriatic acid, such as wearing protective gear and working in a well-ventilated area.
What safety precautions should be taken when using concrete etching acid for a project?
When using concrete etching acid, it is important to wear protective gear such as gloves, goggles, and a mask to prevent skin and eye irritation. Work in a well-ventilated area to avoid inhaling fumes, and follow the manufacturer's instructions carefully to ensure safe handling and disposal of the acid.
What is the best concrete etching solution for preparing a surface for painting or sealing?
The best concrete etching solution for preparing a surface for painting or sealing is a muriatic acid solution. It effectively removes dirt, grease, and other contaminants from the concrete surface, allowing for better adhesion of the paint or sealant. However, it is important to follow safety precautions and instructions when using muriatic acid, as it can be hazardous if not handled properly.
What will increase bonding of old and new concrete?
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.
Can you use apple cider vinegar to etch concrete?
Apple cider vinegar can be used to etch concrete, but it is not as effective as stronger acids like muriatic acid. The acetic acid in vinegar may help remove surface stains and slightly etch the concrete, but the results will be minimal compared to harsher chemicals. For significant etching or preparation for sealing, using a dedicated concrete etching solution is recommended. Always take proper safety precautions when working with any chemicals.
In what household product would you find hydrochloric acid?
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.
