Looking for advice from anyone with experience. My family has built a new hunting cabin on the family farm. It is 1000 square feet on a new concrete slab. We are looking to stain the concrete floors. What kind of stain do I need to use? I see etching acid stains but the colors are very limited. Can I use a non-acid stain instead? We want the semi-transparent stain so that it has a marbled look. Can anyone offer any advice?
