I can't wait to see what kind of traffic the title of this blog draws. Over the past week we have tackled the acid staining of our concrete floor.
Parts of the project were as easy as I thought they would be, and other parts were much more difficult. I'll start from the beginning.
We used kona brown colored stain from Butterfield - mainly because I could get it locally. Most experts recommend doing a test spot in an inconspicuous area. So we did. Our test spot revealed a color we liked and gave us the confidence to continue.
We started by moving everything out of the room.
Once we were finally done cleaning the concrete, it was time to do some acid. I mean stain the floor. We used a hand pump sprayer, just like a garden sprayer. The manufacturer warns you not to use a sprayer with metal parts. I don't know what will happen, but I envision a MacGyver style explosion. Laying the stain down is pretty simple. You just work your way out of the room and let it dry.
Here is another mistake I made that you don't have to. Make sure your stain is completely dry before you neutralize it. It will save you some clean up time. The stuff that is still a bit wet contaminates your clean up solution and makes cleaning up take longer. It may also make some designs you aren't happy with. After it is completely dry, you need to neutralize it with a solution of baking soda and water. Then you need to work your tail off trying to clean up the baking soda residue with clean water - before the residue drys on the surface.
We ended up doing a second coat, mostly to hide some of the mistakes I made when I washed my stain off too early - but partially because we wanted a darker shade.
Halloway House floor finish. Even though mistakes were made, we couldn't be happier with our floor.
