Did you have someone stain your concrete floor and it just turned out horrible? If so you might be interested in knowing how to remove the stain. Depending on what type of stain was used there is two possible ways to remove the stain. If the stain was a water based acrylic stain (paint) you could use a paint stripper to remove the stain from the concrete.
If however the stain was an acid stain or an acetone dye, you will not be able to use any type of strippers to remove or lighten the stain. You will have to grind the concrete with either a hand grinder fitted with a diamond wheel or use a stand behind grinder. Grinding will remove any type of stain that was used, so if your not sure I would begin with grinding the concrete. You want to make sure you don’t use a very aggressive diamond wheel or you will leave a rough profile.
When grinding concrete make sure you have a vacuum and respirator because the concrete dust is very harmful to your lungs. Hope this helps!

Here are a few photos of a recent job we just completed. Before we sealed the concrete, the concrete was ground down to show some light aggregate in the concrete. You can notice in the pictures that the concrete does not appear to be grey but more of a tannish color; a lot of times when we grind the surface of the concrete off, the underlying concrete will be a tannish color.
Concrete grinding and sealing is a very affordable floor option compared to polished concrete. Polished concrete consists of going over the floor over 9 times with a concrete grinder which is very labor intensive; concrete grinding and sealing gives a similar look to polished concrete, except it only consists of going over the floor 2-3 times with a concrete grinding and then applying a film forming sealer.
These concrete floors were ground down with a concrete grinder to expose some small aggregate in the concrete and then sealed with a polyurethane sealer. Concrete grinding and sealing is a great way to achieve a modern look inside a home.
Concrete grinding can fix many problems with surface defects in concrete.
Grinding the concrete can remove the top surface of the concrete that was weak due to a high water content, or it can remove the delaminating parts of the top of the concrete surface. Grinding is an excellent way to even out a concrete surface that was poorly finished.
Grinding is also useful in flattening a floor; whether if its a concrete basketball court, concrete foundation, or just a concrete floor in a warehouse. Concrete floors need to be flat so water won’t pool and so other floor coverings will sit on the surface properly.
Concrete grinding can be used to remove old paint that was used to seal a concrete surface. Grinding will provide a rough surface on the concrete so another coating can bond properly to the concrete. Majority of coating failures are caused by the surface not being prepped the right way.
