What is the difference between acid stain and concrete stain?
The main difference between an acid stain and a water based concrete stain is how they interact with the concrete. Acid stains have a muted more natural coloring. They penetrate into the concrete’s pores and interact with it’s natural coloring.
Are acid stained concrete floors slippery?
Like any hard, smooth surface, stained concrete can become slippery when wet, especially if it has been coated with a high-gloss sealer. For concrete floors or walkways exposed to moisture or in areas with a lot of foot traffic, there are ways you can increase the slip resistance without affecting the color.
How long do you leave muriatic acid on concrete?
Use a brush or sprayer to apply the acid directly over the stained area. Surround the area in question with a neutralizing agent. Leave the acid on for twenty minutes, then scrub. Repeat if needed.
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.
What does hydrochloric acid do to concrete?
Acid etching involves allowing the reaction of a dilute hydrochloric acid solution with the concrete surface, then rinsing off with water. The acid chemically reacts with surface laitance1, dissolving it and allowing it and other water-soluble contaminants to be washed away.
Do you have to acid wash concrete before staining?
Schmidt also warns against acid etching of floors before staining. A lot of people think they need to acid etch the concrete like they do before applying a paint or coating, to get the paint to adhere.

Is acid stain better than water based?
Water-based stains are nonreactive products. They’re more popular than acid stains in some scenarios and in other scenarios they’re not. We’re not depositing pigment, we’re creating a chemical change…so an acid stain is only as effective as the slab’s ability to react.
