Acid is generally mixed at a ratio of 3 parts water to 1 part acid for sufficient strength to etch properly. Ideally you want to test the strength needed first before doing the entire floor. You can do this by first mixing a small solution in your watering can starting at a 5:1 ratio.
How do you etch concrete with muriatic acid?
Clean the concrete surface. Dampen the surface to be etched with clean water. Put on protective gear. Mix an acid solution by pouring 1 part acid into 10 parts water. Pour the mixture into a plastic garden watering can. Sprinkle the mixture evenly across the surface of the prepared concrete.

What happens if you don’t etch concrete before epoxy?
In Closing. New concrete must be etched before applying the epoxy. The smooth surface of unaltered concrete won’t bind with other materials, such as epoxy or paint. As a result, epoxy will peel and lift away, failing to adhere to the surface.
Does vinegar etch concrete?
Etching – Vinegar’s ability to dissolve CaCO3 will dull your marble, travertine, concrete and terrazzo surfaces. It may “clean” the surface but it is also dissolving pits into the finish and effectively dulling it. This will affect marble, travertine, concrete and concrete terrazzo surfaces.
Do you have to acid wash concrete before epoxy?
Concrete floors require preparation before applying an epoxy coating system. The preparation usually involves cleaning the surface to remove oil and other unwanted contaminants and “profiling” the concrete by etching with acid or by mechanical abrasion (ie; shot-blasting or etching with a diamond grinder).
Should you etch old concrete?
Etching is a crucial step in preparing concrete for painting. It gives the surface tooth to adhere to, so your paint is more likely to stick for a long time. Most concrete paints require etching and if they don’t, do it anyway. Don’t skip this step if you want a long-lasting painted concrete floor.
How do you apply hydrochloric acid to concrete?
To clean and etch concrete, mix one part muriatic acid to 10 parts water. Brush or spray the acid solution on the concrete, wait eight to 10 minutes, then neutralize the acid by spraying the surface with a mixture of one cup of ammonia in one gallon of water.
How soon can you paint after etching concrete?
It mostly depends on the type of concrete surface you are etching on. Generally speaking, it can take up to 30 minutes for a surface to be etched and 10 days for the surface to be ready for paint.

Can I sand concrete instead of etching?
Yes, you will need to grind in order to remove the sealer at the surface and provide a proper profile for the coating. You cannot acid etch. The reason is that the sealer prevents the acid from reacting with the minerals in the concrete since the concrete is sealed.
How do you etch a concrete slippery?
3 Answers. You can make the surface a bit rougher by using an acid etch. Muriatic acid & water is commonly used to clean concrete prior to sealing or painting. A strong solution allowed to sit will actually etch the slippery surface away.
How do you seal etched concrete?
To acid etch, you must first dilute the acid, which minimizes its potential danger. Then you must spray the concrete surface with the acid, scrubbing vigorously. Next, you have to neutralize the acid before washing down the concrete surface for a final time.
What does citric acid do to concrete?
Citric acid is an organic acid naturally present in fruits, one of the ingredients that can be used as a retarder in a concrete mixture. The results obtained the greater the addition of citric acid the longer the hardening of concrete and the greater workability of concrete.
Does citric acid etch concrete?
The chemical reaction of citric acid with the top layer of calcium hydroxide creates the etching of the concrete surface. The de- gree of etch is controlled by the strength of the citric acid, dwell time, agitation, and temperature of the substrate.
Do you seal concrete before epoxy?
New slabs of concrete should be allowed to fully cure for 30-60 days before a coating is applied. If a sealer was previously used on the concrete (if water beads up on the surface), do not use epoxy. Any cracks or concrete spall should be filled and stabilized before a new epoxy coating is applied.
Can you seal concrete without etching?
