Moving on to staining the floor. I will say that this ended up being more work than I had planned but there are a few things I should have done a little different in hindsight.
I said earlier that I used Legacy Industrial black acid stain for the floor. My idea behind this was mostly that I didn't want to deal with aged epoxy in 5 or 10 years. The acid stain will get its own nicks and chips but with it being a very organic color pattern, the hope is that it will not show the blemishes later on. Time will tell on that.
While on the topic of Legacy Industrial I have to say that Scotty was great to work with. I am sure he gets these calls all of the time but he took the time to walk me through this project. Thanks!!
The first task is to test the concrete to see how it will color. The acid stain reacts differently to the varying compositions of the concrete so the colors will be different between each application of different finished slabs. That and I wanted to get a marbled light grey with black in some areas.
My test location was the shop which is the small room at the top of the far RH single garage. I was going to go ahead and stain this anyway and was OK if there was some differences there. Benches will line the walls and hide most mistakes anyway.
My first sample is the larger area. I purposely made it a light coat with the thought that I could add more later to get the dark spots. I needed to do that so that is why there is a dark section surrounded by a lighter section.
I ended up liking this a lot. After the acid does its thing you wash it off to get the loose stuff off. At the same time you get to see it wet and that is an indicator of how t will look with the clear epoxy on when it's all done.
So far, so good. Wrong. This ended up being where I made first mistake.
I went ahead and stained the floor. This is seriously messy stuff and comes out in the yellowish-brownish liquid. It is about the viscosity of water and it is easy to splash it on the walls. You'll see that soon enough.
There are a few ways to apply this. I had tried the spraying bu that ended up being too messy on my newly pained walls so I went with a mop. It is not easy (impossible) to wring out a mop with this acid stain in it so I used a cheap one that would not hold much.
