Can I Use a Grinder to Roughen the Surface of My Concrete Instead of Acid Etching?
Yes. Using a grinder is a great method for surface profiling concrete. However, it is very labor-intensive and there is a risk of damaging the surface of the concrete if the person doing the grinding is inexperienced. This process usually calls for a professional, which can be costly. Etching concrete with muriatic acid is by far the most cost-effective method.
