We ripped up the carpets then we set forth to clean, and scrape off the glue and white residue that is on concrete. We rented a big rotary polisher/scrubber thingy, put our rubber boots on and scrubbed some more. It took a full day to get the concrete clean enough for our intents and purposes.
I did my measuring and computing for the faux tile design I am going to stain. then we had to tape it off in the proper grids.
After all the cleaning and scraping, sanding, scouring and so forth there are still many bits of residue and discoloration in the concrete. My back is sore and I also think that because I am using Behr concrete stain (which soaks into the concrete and residue) instead of an acid stain ( which would react with the chemicals in the concrete) the residue and white stuff will blend and add character. So we are done with the scrubbing.
After all the cleaning let it dry then use some sort of concrete repair or thin set concrete to fill any holes or gouges, large cracks etc. Allow that to dry then sand smooth. Vacuum, use a damp cloth to pick up any extra dust allow to dry again...
Then you can tape off your design. Or use stencils, etch with a dremel whatever you desire. after that is over make certain there is no particles etc and begin the staining.
I wanted to point out a problem we have to deal with on our floor.... the spray painted J.A. you can see it above in the photo. I am hoping it disappears with the many coats of stain that we are going to
I will post more later after I actually stain the concrete.
I think this can save you a huge chunk of change on changing your flooring, *but* it is labor intensive and you need to stay focused and complete all the steps if you want a nice looking finished product.
Stay tuned... see If I stay focused and end up with a nice looking finished product.
